I have problem with 4 ifs in my code on jsf. I have to check 3 parameteres and when it is ok show appropriate message. Why its doesn't work? In dataGrid it works in c:when
<h:outputLabel value="#{msg.deleted}" class="delete" rendered="#{((!advertisement.isStarted) and (!advertisement.isActive) and (!advertisement.isFinished))}"/>
<h:outputLabel value="#{msg.done}" class="done" rendered="#{((advertisement.isStarted) and (!advertisement.isActive) and (advertisementisFinished))}"/>
<h:outputLabel value="#{msg.realize}" class="realize" rendered="#{((advertisement.isStarted) and (advertisement.isActive) and (!advertisement.isFinished))}"/>
<h:outputLabel value="#{msg.open}" rendered="#{((!advertisement.isStarted) and (advertisement.isActive) and (!advertisement.isFinished))}"/>
All time I dont understand solution of BalusC
I have:
public boolean isIsActive() {
return isActive;
}
public void setIsActive(boolean isActive) {
this.isActive = isActive;
}
public boolean isIsStarted() {
return isStarted;
}
public void setIsStarted(boolean isStarted) {
this.isStarted = isStarted;
}
public boolean isIsFinished() {
return isFinished;
}
public void setIsFinished(boolean isFinished) {
this.isFinished = isFinished;
}

I'm unable to set true false value to a boolean variable
I have the following code
Form.xhtml
<ui:composition xmlns="http://www.w3.org/1999/xhtml">
<h:form>
<p:panel id="work" styleClass="panelNoBorder">
<p:fieldset toggleable="true" toggleSpeed="500" legend="Core">
<h:panelGrid columns="2" styleClass="panelNoBorder"
rendered="#{javaMB.formNotComplete and !javaMB.formRejected}">
<p:outputLabel value="Form Number"/>
<p:row>
<p:inputText id="formNumber" value="#{javaMB.formNumber}" maxlength="10">
</p:inputText>
</p:row>
<p:outputLabel value="Result"/>
<p:row>
<p:inputText id="result" maxlength="10"
value="#{javaMB.result}">
</p:inputText>
</p:row>
</h:panelGrid>
</p:fieldset>
</p:panel>
</h:form>
</ui:composition>
public class JavaMB {
private boolean formRejected = false;
private boolean formNotComplete = true;
public boolean isFormRejected() {
return formRejected;
}
public void setFormRejected(boolean formRejected) {
this.formRejected = formRejected;
}
public boolean isFormNotComplete() {
return formNotComplete;
}
public void setFormNotComplete(boolean formNotComplete) {
this.formNotComplete = formNotComplete;
}
public void initializeWorkFlow() {
logger.debug("Form: " + FormEntity.getFormId());
if (workflow.getActionType().getActionTypeId() == '5') {
this.setFormNotComplete(false);
} else if (workflow.getActionType().getActionTypeId() == '7') {
this.setFormRejected(true);
} else {
}
}
}
The set values are placed inside an if statement , The if Statements work perfectly fine
The problem is that I can't display correctly boolean value. There are NO errors in the console,
this.setFormNotComplete(false);
this.setFormRejected(true);
Any ideas how to solve this issue?
the database has the values for Approved and Not approved, So if the record has a 5 or 7 It must hit those values and not display the panel
In database we have a table workflow and the action type IDs
The action type Ids being set to record has a 5 being approved or 7 being Rejected
Upon these values the setFormNotComplete(false 7 if setFormRejected(true must act
<h:panelGrid
rendered="#{javaMB.formNotComplete and !javaMB.formRejected}">
if (workflow.getActionType().getActionTypeId() == '5') {
this.setFormNotComplete(false);
} else if (workflow.getActionType().getActionTypeId() == '7') {
this.setFormRejected(true);
} else {
For boolean fields the getter method name should be is<First letter capitalised field name> but yours is not.
public boolean isformRejected() should be public boolean isFormRejected() and public boolean isformNotComplete() should be public boolean isFormNotComplete()
So your class should be as follows.
public class JavaMB {
private boolean formRejected = false;
private boolean formNotComplete = true;
public boolean isFormRejected() {
return formRejected;
}
public void setFormRejected(boolean formRejected) {
this.formRejected = formRejected;
}
public boolean isFormNotComplete() {
return formNotComplete;
}
public void setFormNotComplete(boolean formNotComplete) {
this.formNotComplete = formNotComplete;
}
public void initializeWorkFlow() {
logger.debug("Form: " + FormEntity.getFormId());
if (workflow.getActionType().getActionTypeId() == '5') {
this.setFormNotComplete(false);
} else if (workflow.getActionType().getActionTypeId() == '7') {
this.setFormRejected(true);
} else {
}
}
}
I am studying a PrimeFaces AutoComplete demo. I shortenied it from the full showcase demo. http://www.primefaces.org/showcase/ui/input/autoComplete.xhtml
AutoCompleteBean.java
#ManagedBean
public class AutoCompleteBean {
private Query query;
private List<Query> queries = new ArrayList<Query>();
#PostConstruct
public void init() {
queries.add(new Query(0, "Afterdark", "afterdark"));
queries.add(new Query(1, "Afternoon", "afternoon"));
queries.add(new Query(2, "Afterwork", "afterwork"));
queries.add(new Query(3, "Aristo", "aristo"));
}
public List<Query> completeQuery(String query) {
List<Query> filteredQueries = new ArrayList<Query>();
for (int i = 0; i < queries.size(); i++) {
Query skin = queries.get(i);
if(skin.getName().toLowerCase().contains(query)) {
filteredQueries.add(skin);
}
}
return filteredQueries;
}
public void onItemSelect(SelectEvent event) {
FacesContext.getCurrentInstance().addMessage(null, new FacesMessage("Item Selected", event.getObject().toString()));
}
public Query getQuery() {
return query;
}
public void setQuery(Query query) {
this.query = query;
}
}
Query.java
public class Query {
private int id;
private String displayName;
private String name;
public Query() {}
public Query(int id, String displayName, String name) {
this.id = id;
this.displayName = displayName;
this.name = name;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getDisplayName() {
return displayName;
}
public void setDisplayName(String displayName) {
this.displayName = displayName;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
#Override
public String toString() {
return name;
}
}
I omitted a Convert class, which I think is not that relevant.
search.xhtml
<h:form>
<p:growl id="msgs" showDetail="true" />
<h:panelGrid columns="2" cellpadding="5">
<p:autoComplete id="queryPojo" value="#{autoCompleteView.query}"
completeMethod="#{autoCompleteView.completeQuery}" var="query"
itemLabel="#{query.displayName}" itemValue="#{query}"
converter="queryConverter" forceSelection="true" />
<p:commandButton value="search" oncomplete="PF('dlg').show()"/>
</h:panelGrid>
</h:form>
I have three questions for this:
1) completeMethod="#{autoCompleteView.completeQuery}": completeQuery method is called without passing a parameter, but it's defined as completeQuery(String query). How does this work?
2) value="#{autoCompleteView.query}". Query is an object defined in AutoCompleteBean. How can this Query object take user input string as its value? Usually InputText's value is good for taking user's input, which is a String value.
3) Can I still add an attribute "action=..." to the p:autoComplete componenet?
The converter class that you omitted here plays the real game.... Lets see your questions
As you see converter class overrides 2 methods
getAsString and getAsObject
1)the value
completeMethod="#{autoCompleteView.completeQuery}
gets refactred to
autoCompleteView.completeQuery(autoCompleteView.query);
as you can find to string method in Query class.
2).as converter is defined for autocomplete it calls getAsString method to render on screen. when selected getAsObject method is called to convert string value to object(Query).
3)you can use ajax select event
<p:ajax event="select" listener="#{autoCompleteView.someMethod}">
or call a remoteCommand by onSelect attribute in p:autoComplete
<p:autoComplete id="queryPojo" value="#{autoCompleteView.query}" onSelect="someRemoteCommand();"
completeMethod="#{autoCompleteView.completeQuery}" var="query"
itemLabel="#{query.displayName}" itemValue="#{query}"
converter="queryConverter" forceSelection="true" />
<p:remoteCommand name="someRemoteCommand" update="queryPojo" actionListener="#{autoCompleteView.execute}" />
Originally I have this form for user input and do a search.
<h:form id="wordForm">
<h:panelGrid columns="4">
<h:inputText id="word" "
value="#{wordController.word}" />
<h:message for="word" />
<h:commandButton id="search" value="search"
action="#{wordController.search}" />
</h:panelGrid>
</h:form>
Now I want to use PrimeFaces for autocomplete feature, and this is my new form with Autocomplete. How can I replace the new form with the above form?
<h:form>
<p:growl id="msgs" showDetail="true" />
<h:panelGrid columns="2" cellpadding="5">
<p:autoComplete id="wordForm" value="#{autoCompleteView.query}"
completeMethod="#{autoCompleteView.completeQuery}" var="query"
itemLabel="#{query.displayName}" itemValue="#{query}"
converter="queryConverter" forceSelection="true" />
<p:commandButton value="search" oncomplete="PF('dlg').show()" **action="#{wordController.search}"** />
</h:panelGrid>
</h:form>
More specifically, I think I still need to somehow use "action="#{wordController.search}" in P:CommandAction button so that I don't need to change anything else in backend. But How do I pass the query parameter to the "wordController.word" variable? Because now "action="#autoCompleteView.query" takes the user input.
How can I modify this without significant change to current bean code? Do I have to unify the original search bean WordController with the new AutocompleteView bean? because now the user input is accepted into AutoCompleteView bean.
AutoCompleteView.java
#ManagedBean
public class AutoCompleteView {
private Query query;
#ManagedProperty("#{queryService}")
private QueryService service;
private List<Query> selectedQueries;
public List<Query> completeQuery(String query) {
System.out.println(query);
List<Query> allQueries = service.getQueries();
List<Query> filteredQueries = new ArrayList<Query>();
for (int i = 0; i < allQueries.size(); i++) {
Query skin = allQueries.get(i);
if(skin.getName().toLowerCase().contains(query)) {
filteredQueries.add(skin);
}
}
return filteredQueries;
}
public void onItemSelect(SelectEvent event) {
FacesContext.getCurrentInstance().addMessage(null, new FacesMessage("Item Selected", event.getObject().toString()));
}
public Query getQuery() {
return query;
}
public void setQuery(Query query) {
this.query = query;
}
public void setService(QueryService service) {
this.service = service;
}
public List<Query> getSelectedQueries() {
return selectedQueries;
}
public void setSelectedQueries(List<Query> selectedQueries) {
this.selectedQueries = selectedQueries;
}
}
Edited per suggestion:
#Named
#RequestScoped
public class WordController {
private String word;
// For AutoComplete suggestions
private Query selectedQuery;
#Inject
private QueryService service;
#Inject
private Word wordObject;
public void search() {
if (word != null && !word.isEmpty()) {
wordObject.searchWord(word);;
...
}else {
System.out.println("Query can't be null!");
}
}
public List<Query> completeQuery(String query) {
List<Query> allQueries = service.getQueries();
List<Query> filteredQueries = new ArrayList<Query>();
for (int i = 0; i < allQueries.size(); i++) {
Query skin = allQueries.get(i);
if(skin.getName().toLowerCase().contains(query)) {
filteredQueries.add(skin);
}
}
return filteredQueries;
}
public String getWord() {
return word;
}
public void setWord(String word) {
this.word = word;
}
public Query getSelectedQuery() {
return selectedQuery;
}
public void setSelectedQuery(Query selectedQuery) {
this.selectedQuery = selectedQuery;
}
}
Question: Originally, my 'word' is filled through an "h:inputText" in JSF view and search() is called in JSF:
<h:commandButton id="search" value="Search!" action="#{wordController.search}" />
Now, how do I get "selectedQuery" from completeQuery() method, and then use it to fill "word" and then call search() method?
I am currently implementing a orderable list using PrimeFaces' component, embedded inside a . I was able to get the list to appear properly with my items. However, when I saved the list and submitted it back to the server, the rearranged items did not get reflected in the backing bean for some reason. Since the Primefaces showcase was able to see the changes, what am I doing wrong?
XHTML Snippet:
<h:form id="confirmDialogForm">
<p:confirmDialog id="arrangeProjDialog" widgetVar="arrangeDlg" width="600"
header="Meeting Order"
appendToBody="true" message="Drag and drop to rearrange meeting order">
<p:orderList id="arrangeProjDialogList"
value="#{adminMeetingListBean.orderProjList}"
converter="#{adminMeetingListBean.rowConverter}"
var="po"
controlsLocation="left"
styleClass="wideList"
itemLabel="#{po.projectTitle}"
itemValue="#{po}"
>
<f:facet name="caption">Proposals</f:facet>
</p:orderList>
<p:commandButton value="Save" ajax="true" process="arrangeProjDialogList #this"
actionListener="#{adminMeetingListBean.updateProposalMeetingOrder}" onclick="arrangeDlg.hide();">
</p:commandButton>
<p:button value="Cancel" onclick="arrangeDlg.hide(); return false;" />
</p:confirmDialog>
</h:form>
Backing Bean:
public void updateProposalMeetingOrder() {
if (selectedMeeting != null) {
orderProjTitles.get(0);
meetingService.updateMeetingProjSequence(orderProjList, selectedMeeting.getMeetingId());
}
}
The List is a list of POJO "ProposalOrderRow" objects. This has the definition:
public class ProposalOrderRow implements Serializable {
private static final long serialVersionUID = -5012155654584965160L;
private int dispSeq;
private int appId;
private int assignmentId;
private String refNo;
private String projectTitle;
public int getDispSeq() {
return dispSeq;
}
public void setDispSeq(int dispSeq) {
this.dispSeq = dispSeq;
}
public int getAppId() {
return appId;
}
public void setAppId(int appId) {
this.appId = appId;
}
public String getRefNo() {
return refNo;
}
public void setRefNo(String refNo) {
this.refNo = refNo;
}
public String getProjectTitle() {
return projectTitle;
}
public void setProjectTitle(String projectTitle) {
this.projectTitle = projectTitle;
}
public int getAssignmentId() {
return assignmentId;
}
public void setAssignmentId(int assignmentId) {
this.assignmentId = assignmentId;
}
}
Converter:
#FacesConverter("proposalOrderRowConverter")
public class ProposalOrderRowConverter implements Converter {
private List<ProposalOrderRow> orderRows;
#Override
public Object getAsObject(FacesContext context, UIComponent component, String newValue) {
if (newValue.isEmpty()) {
return null;
}
for (ProposalOrderRow item : orderRows) {
String refNo = item.getRefNo();
if (refNo.equals(newValue)) {
return item;
}
}
return null;
}
#Override
public String getAsString(FacesContext context, UIComponent component, Object value) {
if (value == null) {
return "";
}
ProposalOrderRow row = (ProposalOrderRow) value;
String output = row.getRefNo();
return output;
}
public List<ProposalOrderRow> getOrderRows() {
return orderRows;
}
public void setOrderRows(List<ProposalOrderRow> orderRows) {
this.orderRows = orderRows;
}
}
This problem is caused by appendToBody="true" in the confirm dialog. Setting it to false solved the problem.

I have a simple page where a I use <ui:repeat> and it gets the value from a backing bean.
The initial request will give it an empty list. The postback then will invoke an action that will change the model behind the <ui:repeat> but it is not rendered?!
I debugged through it and I saw that the <ui:repeat> evaluates the value at restore view phase but thats it. When it reaches render response it does not use the latest value from my bean. Is that the expected behavior?
How can I make that work? Do I have to write my own repeat tag?
I can't really tell what could be the problem without some of your code, but these are the basics:
Backing bean:
public class ObjectService{
private DataModel objectDataModel;
private List<Object> objectList;
private Pagination paginationHelper;
private ObjectDao objectDao = new ObjectDao();
private String queryOption;
public void setQueryOption(String queryOption){
this.queryOption = queryOption;
}
public String getQueryOption(){
return this.queryOption;
}
public <E> PaginationHelper getPagination(final List<E> list) {
pagination = new PaginationHelper(10) {
#Override
public int getItemsCount() {
return list.size();
}
#Override
public DataModel createPageDataModel() {
return new ListDataModel(list);
}
};
return pagination;
}
public void setPagination(PaginationHelper pagination) {
this.pagination = pagination;
}
public List<Object> getObjectList(){
this.objectList = objectDao.readObjectsWhere(queryOption);
return this.objectList;
}
public void setObjectList(List<Object> objectList){
this.objectList = objectList;
}
public DataModel getObjectDataModel(){
if (objectDataModel == null) {
objectDataModel = getPagination(getObjectList()).createPageDataModel();
}
return objectDataModel;
}
public void setObjectDataModel(DataModel objectDataModel){
this.objectDataModel = objectDataModel
}
public String changeModel(){
objectDataModel = null;
return null;
}
}
XHTML page:
...
<h:form>
<fieldset>
<label>
<span>Option:</span>
<h:inputText value="#{objectService.queryOption}" />
</label>
<h:commandButton action="#{objectService.changeModel}" value="request data" />
