I am new to this Website My issue is related to SelectBooleanCheckbox in primefaces.
Whenever I submit my form, the checkbox gets unchecked.
I am using dynamic tabview.
Here is my xhtml code:-
<h:form id="form" >
<p:panel id="tagsPanel" >
<p:tabView id="tabView" style="background-color:transparent;background-image:none;" var="tabKey" value="#{MBean.Names}"
dynamic="true" >
<p:dataGrid var="appSettingsList" value="#{appSettingsMBean.tabData[tabKey]}" columns="1" styleClass="plainDataGrid">
<h:panelGrid columns="2" border="0" cellspacing="0" cellpadding="0" columnClasses="JspContent12 ,JspContent22" width="100%" >
<p:column escape="false" >
<p:selectBooleanCheckbox value="#{appSettingsList.resultValues.checkboxValue}" style="float:left" id="checkBoxValue"
rendered="#{appSettingsList.currentValues != null and appSettingsList.currentValues.size() > 0 and
appSettingsList.displayType.equalsIgnoreCase('single') and appSettingsList.dataType.equalsIgnoreCase('boolean')}">
</p:selectBooleanCheckbox>
</p:column>
</h:panelGrid>
</p:dataGrid>
</p:panel>
<p:panel border="0" id="buttonRow" style="text-align:center;border-width:0;border-style:none;background-image:none;" >
<p:commandButton value="Save" id="save" actionListener="#{MBean.saveSettings()}" ajax="false" style="width:130px" />
</p:panel>
</h:form>
The checkboxes remain checked when tabs are changed and save btn is clicked
But,when only the save btn is clicked,it gets unchecked
Any help will be appreciated...
Here,
<p:commandButton ... ajax="false" />
Ajax is turned off. Thus a full page refresh is performed after submitting the form. That the checkbox got unchecked suggests that the bean doesn't properly keep its state, or that you're performing business logic in a getter method, which causes it to return a fresh new model everytime instead of the one holding the submitted values.
You've 2 options:
Just use ajax. I.e. get rid of ajax="false". If you intend to update certain parts of the view on submit, then just specify update attribute accordingly.
Make sure that your bean doesn't mess with the state or getters.

So i have designed a simple form having selectOneListbox / selectManyMenu elements which I am using to generate a piece of text based upon the user selections.
It's working fine. Now what I want is when the user clicks 'clear' button, the selections should be undone and the page should come back to the initial state(no selections).
How can I achieve this ?
xhtml
<h:form>
<h:panelGrid columns="6" style="margin-bottom:10px;" cellpadding="5" columnClasses="label, value">
<p:panel>
<h6 style="width:10.4em;background-color:#ACBECE;">Comment Type</h6>
<!-- comment type -->
<p:selectOneListbox id="basic1" value="#{decisionTreeBean.option1}" style=" font-size: 12px;background-color:silver;width:12em; height:10em; border-style:solid !important;border-width:0.5px !important; border-color:grey !important;">
<f:selectItems value="#{decisionTreeBean.commentType}" var="X" itemLabel="#{X}" itemValue="#{X}" />
</p:selectOneListbox>
</p:panel>
<p:panel>
<h6 style="width:10.4em;background-color:#ACBECE;">MTCN</h6>
<p:selectManyMenu id="advanced1" value="#{decisionTreeBean.option2}" showCheckbox="true" style="font-size: 12px;background-color:silver;width:12em; height:10em; border-style:solid !important;border-width:0.5px !important; border-color:grey !important;">
<f:selectItems value="#{decisionTreeBean.mtcns}" var="X" itemLabel="#{X}" itemValue="#{X}" />
</p:selectManyMenu>
</p:panel>
</h:panelGrid>
<!-- Text Area -->
<p:inputTextarea id="decisionNotes" readonly="#{facesContext.renderResponse}" value="#{decisionTreeBean.decisionNotes}" styleClass="dispostionInputTextArea" autoResize="true">
</p:inputTextarea>
<br/>
<p:commandButton id="generateBtn" value="Generate Text" action="#{decisionTreeBean.generateText}" update=":#{p:component('decisionNotes')}">
</p:commandButton>
<p:commandButton id="clearBtn" value="Clear" action="#{decisionTreeBean.clearText}" update=":#{p:component('decisionNotes')}">
</p:commandButton>
<p:ajaxStatus onstart="PF('statusDialog').show()"
onsuccess="PF('statusDialog').hide()" />
<p:dialog widgetVar="statusDialog" modal="true" draggable="false"
closable="false" resizable="false" showHeader="false">
<p:graphicImage value="/images/ajax-loader.gif" />
</p:dialog>
</h:form>
In my bean, I have a clear method which clears the content of the textarea. I want this button to undo the selections as well as part of the ajax call.
public void clearText() {
this.decisionNotes=" ";
}
(for brevity I have included just 2 columns here in xhtml. There are in total 5 separate selection columns with same functionality)
I would simply reset the values of the Menu/Box in the bean method too:
public void clearText() {
this.decisionNotes=" ";
this.option1 = null;
//and so on...
}
Then you just need to update the components in the update attribute of your button. But I'd update the whole form instead of each component if you want to refresh nearly each component in the form. So just use update="#form":
Note: The default process value of p:commandButton is #form. So your clear button will process the whole form on every click altough it doesn't need to. I'd set it to process="#this", so it will just perform it's action.
I have a table in a form. One of the columns in the table displays a row of buttons to edit and delete the table entries. When I delete an entry callign the controller from a button's action attribute, it works as expected.
But once I have added a dialog to let the user confirm the deletion, a wrong entry is deleted. It is always the last entry in the current table. I have no idea what the reason could be - I am using the same DataTable var for the button and for the dialog.
I am working with JSF 2 (Mojarra 2.1.6) and Primefaces 3.5 deploying on JBoss 7.1.1 on a Suse 12.2 machine.
The form:
<h:form id="downloads">
<ui:include src="components/table.xhtml"/>
</h:form>
The table:
<ui:composition>
<p:dataTable value="#{controller.currentLevelResources}"
var="download" id="downloadTable" scrollHeight="120" rows="10">
<p:column sortBy="#{download.name}">
<f:facet name="header">Name</f:facet>
<h:outputText id="downloadName" value="#{download.name}" title="#{download.description}" />
</p:column>
...
<p:column>
<ui:include src="menuBar.xhtml"></ui:include>
</p:column>
The menu bar:
<ui:composition>
<p:commandButton id="edit"
action="#{downloadEditController.editResource(download)}"
icon="ui-icon-gear" title="Edit" oncomplete="updateStyles()"
update=":downloads" />
<p:commandButton id="delete" onclick="deletedDlg.show();"
icon="ui-icon-trash" title="Delete" oncomplete="updateStyles()" />
<p:dialog header="Delete confirmation" widgetVar="deletedDlg"
resizable="false">
<h:panelGroup layout="block" style="padding:5px;">
<h:outputText
value="The Resource #{download} will be deleted. Proceed?" />
</h:panelGroup>
<p:commandButton id="deleteBtn" value="Delete"
oncomplete="deletedDlg.hide(); updateStyles(); "
action="#{downloadEditController.deleteResource(download)}"
process="#this" update=":downloads">
</p:commandButton>
<p:commandButton value="Cancel" type="button"
onclick="deletedDlg.hide();" />
</p:dialog>
If I replace the dialog with this, everything works:
<p:commandButton id="delete" icon="ui-icon-trash" title="Delete"
action="#{downloadEditController.deleteResource(download)}"
oncomplete="updateStyles()" update=":downloads" />
Creating a <p:dialog> for every row is not a good idea.
For starters you had better create a single <p:dialog> outside your <p:dataTable>.
Next thing that I would do is to set the id or the row var in your bean upon delete button click and in case of confirmation in dialog use that id or the row var from bean to delete.
This is how your delete button could look like, set the download var in prepareDataForDeletion action and show the dialog...
<p:commandButton id="deleteConfirmation" icon="ui-icon-trash" title="Delete"
action="#{downloadEditController.prepareDataForDeletion(download)}"
onsucess="deletedDlg.show();"/>
Regarding your current anomaly: it's because all your dialogs have the same widgetVar and each next one is overriding the previously declared one all the way until the last one. You could dynamically give them a different widget names like so widgetVar="deleteDlg_#{someIndex}", but this makes no sense if you can have just only one reusable dialog whose content is updated before opening.
I use a Primefaces carousel component to display a list of items. What i would like to do is show a commandButton on every carousel item which triggers a method on the bean to confirm or decline the entry.
Now it works only for the first entry of the carousel. Clicking on another entry does not invoke the action confirmResource. I guess it has something to do with the IDs but i can't figure it out.
Here's the form:
<h:form id="form" prependId="false">
<p:carousel id="resourceCarousel" value="#{resourceRatingBean.resourceProposalList}" var="var" rows="1" itemStyle="width:500px; height: 400px; text-align:center;" circular="true">
<p:column>
<h:panelGrid columns="1" cellpadding="3">
<p:graphicImage value="/cache/images/#{var.imagePath}" width="100"/>
<h:outputText value="#{var.imagePath}" />
<h:outputText value="#{var.name}" />
<h:outputText value="#{var.description}" />
</h:panelGrid>
<p:commandButton value="confirm" action="#{resourceRatingBean.confirmResource}" process="#this">
<f:setPropertyActionListener value="#{var}" target="#{resourceRatingBean.ratedResource}" />
</p:commandButton>
</p:column>
</p:carousel>
</h:form>
I see two likely problems here:
The process="#this" is likely an issue as this will only invoke the process of the invoke the action of the commandButton and not the changes in the carousel component. Try setting this attribute to resourceCarousel or #form instead.
If you are still having issues and using JSF 2 + EL 2.2, then instead of depending on setPropertyActionListener to set the value of a managed property, then instead you can pass the argument var to an actionListener method through an EL expression.
Here is an example:
<p:commandButton value="confirm" actionListener="${resourceRatingBean.confirmResourceListener(var)}"
this="resourceCarousel" />
I do not know if this is possible using just primefaces and JSF but I have a panel, which is collapsed on View Entry. I can open the Panel which has a checkbox that triggers an update of the Panel.
The problem is that when the panel is updated by Ajax, the Panel is collapsed again. But I want to retain the current open status of the Panel. It should no close on update. Is this possible?
I use PF 3.2 and JSF2.1
<p:fieldset style="width:200px;height:300px;overflow:auto;">
<h:outputLabel value="Available Applications"
style="font-weight: bold;font-size: 14px;" />
<br />
<br />
<h:panelGroup>
<ui:repeat var="category"
value="#{epsEditController.subscriptionCategoryVOs}">
<p:panel header="#{category.applicationCategory.name}"
id="panell" toggleable="true" closable="false" toggleSpeed="500"
collapsed="true"
widgetVar="panel_#{category.applicationCategory.name}">
<h:panelGrid columns="2" border="0">
<h:outputLabel value="Select all"
style="font-weight: bold;float:left;" />
<p:selectBooleanCheckbox value="#{category.allSelected}">
<p:ajax event="change"
listener="#{epsEditController.selectionChanged(category)}"
update="panell" />
</p:selectBooleanCheckbox>
</h:panelGrid>
<ui:repeat var="subcat"
value="#{category.applicationSubcategoryVOs}">
<p:selectBooleanCheckbox value="#{subcat.selected}"
title="#{subcat.applicationSubcategory.name}"
itemLabel="#{subcat.applicationSubcategory.name}" />
</ui:repeat>
</p:panel>
</ui:repeat>
</h:panelGroup>
</p:fieldset>
The reason the panel was collapsed after each update is caused by using a static collapsed="true" on the panel. This can be fixed in one of two ways
Just updating the content of the panel and not the panel
Keeping track of the state of collapsed state of the panel via ajax and use that state as the value of the collapsedattribute
Updating the content
By putting the form within the panel and only updating that form you effectively update the content instead of the panel. This makes sure that only the form is refreshed and the panel state is kept intact.
<p:panel header="#{category.applicationCategory.name}" id="panell"
toggleable="true" closable="false" toggleSpeed="500"
collapsed="true"
widgetVar="panel_#{category.applicationCategory.name}">
<h:form id="epsAppForm">
<h:panelGrid columns="2" border="0">
<h:outputLabel value="Select all"
style="font-weight: bold;float:left;" />
<p:selectBooleanCheckbox value="#{category.allSelected}">
<p:ajax event="change"
listener="#{epsEditController.selectionChanged(category)}"
update="#form" />
</p:selectBooleanCheckbox>
</h:panelGrid>
........
</h:form>
</p:panel>
Using EL instead of a fixed value
You can put EL in the collapsed attribute instead of the fixed collapsed="true". Something like
collapsed="#{myBean.toggleStates[category.applicationCategory]}"
You can then keep track of the state of the pannel via ajax calls
<p:ajax event="toggle" listener="#{myBean.toggleState(category.applicationCategory)" />
...'myBean' code:
Map<ApplicationCategory, boolean> toggleStates = new HashMap<>();
... prepopulate toggleStates on #init or something
public void toggleState(ApplicationCategory myCategory) {
toggleStates.put(myCategory, !(toggleStates.get(myCategory));
}
I have a composite displayed inside a dialog. I have an edit button that get the current bean #SessionScoped (item in a data table) and then update the UI. My app is very similar to a simple CRUD app like http://balusc.blogspot.com/2010/06/benefits-and-pitfalls-of-viewscoped.html.
The problem is that the UI is updated correctly when using <h:outputText/> but not when using a form element.
<h:inputTextarea value="#{cc.attrs.managedBean.assertionStatement}" />
<h:inputText value="#{cc.attrs.managedBean.assertionStatement}" />
<h:outputText value="#{cc.attrs.managedBean.assertionStatement}"/>
The UI shows an empty textarea and input but the outputText renders the correct value. The getAssertionStatement() is called 3 times which seems to be the correct behavior.
When I close the dialog and reopen it, everything (form element) is populated.
The dialog call (ag namespace is for composite component):
<p:dialog widgetVar="DataValueRuleDialog" modal="true" height="600" width="800">
<p:outputPanel id="DataValueRulePanel">
<ag:DataValueAssertion managedBean="#{dataValueAssertionController}" id="DataValueComposite" />
</p:outputPanel>
</p:dialog>
The composite that calls another composite:
<h:form id="DataValueForm">
<ag:assertionMetadataComponent
managedBean="#{cc.attrs.managedBean.dataValueAssertionBean.assertionMetadataBean}"
assertionStatementRows="5" />
<p:dataTable value="#{cc.attrs.managedBean.model}" var="item">
<p:column>
<f:facet name="header">Assertion Statement</f:facet>
<h:outputText rendered="#{item.profileBean.profileLocation == cc.attrs.managedBean.selectedComformanceProfile.name}" value="#{item.assertionMetadataBean.assertionStatement}" />
</p:column>
<p:column>
<p:commandButton rendered="#{item.profileBean.profileLocation == cc.attrs.managedBean.selectedComformanceProfile.name}" value="edit" immediate="true"
actionListener="#{cc.attrs.managedBean.editDataValueAssertion}" update=":DataValueComposite:DataValueForm">
</p:commandButton>
</p:column>
</p:dataTable>
</h:form>
When I remove the immediate=true the form is validated and since one of the required field (supposed to be populated) is missing, I got a validation error. This is why I have immediate=true but it should be necessary since all the items in the data table should be valid.
