I have the following usage of the p:selectOneMenu:
<p:selectOneMenu id="selectField"
value="#{someBean.someField}"
converter="#{selectItemConverter}" var="x" editable="true">
<f:selectItems
value="#{selectItemsBean.getSelectItems(tab, field)}" var="si"
itemLabel="#{si.label}" itemValue="#{si}" />
<p:column>
<h:outputText value="#{si.label}" />
</p:column>
<p:column>
<h:graphicImage library="images" name="noway_16x16.png"
title="#{si.disabledReason}" rendered="#{si.disabled}" />
</p:column>
<p:ajax event="change" update="#form" partialSubmit="true" process="selectField" />
</p:selectOneMenu>
As you can see, I use custom content in combination with editable=true. When I submit the form, the Converter gets the label of a selected item as the value, not the actual value. In the HTML page, the values are correct, e.g. <option value="C">C-style mounting</option>. With editable=false, the correct value (e.g. C is sent to the converter, with editable=true the converter retrieves C-style mounting.
What I want is that the user can either select one of the pre-defined items in the list and the server submits that value of the item OR the user enters something and that is submitted as value. But the current behavior is a bit strange - or am I just wanting too much?

I'm new to jsf and not sure how to frame the question in a right way. I'm doing a name lookup functionality and my input form is as follows:
Accept input from a text field.(Backed by managed bean and
getters and setters)
Invoke the action using command button.
Display it back on the UI.
I'm not able to paste the entire code because of confidentiality.
<h:form>
<p:outputLabel value="ABC" />
<p:inputText id="a" value="#{mybean.variable}" size="10" />
<p:commandButton value="Check" actionListener="#{mybean.getName()}" update="name">
</p:commandButton>
<p:inputText id="name" value="#{mybean.Value}" />
</h:form>
The above mentioned works fine,However I have 5 input text fields and their corresponding action methods like as follows:
<p:outputLabel value="DEF" />
<p:inputText id="b" value="#{mybean.variable1}" size="10" />
<p:commandButton value="Check" actionListener="#{mybean.getName()}" update="name" >
</p:commandButton>
<p:inputText id="name" value="#{mybean.Value}" />
</h:form>
and so on.
When I put all the text boxes and their corresponding actions,the input is not passed to the backend and the console does not display anything.
Any help appreciated.
Thanks.
I want to make a footer in dataTable and I need to update when the values inside the DT changes.
The problem is that ajax update simply don't occurs.
I've tried two ways:
<p:dataTable
id="dataTableAvaliacao" var="aluno"
value="#{alunoAvaliacaoMB.alunos}">
<p:column>
<p:inputText id="inputNota"
value="#{aluno.getNota(avaliacao.property).vlNotaString}">
<p:ajax event="change"
update=":form:dataTableAvaliacao:mediaAluno, :form:dataTableAvaliacao:mediaAvaliacao" />
</p:inputText>
</p:column>
<p:columnGroup type="footer" id="mediaAvaliacao">
<p:row>
<p:column
footerText="Nota média da avaliação" />
</p:row>
<p:row>
<ui:repeat value="#{alunoAvaliacaoMB.colunasAvaliacoes}"
var="avaliacao">
<p:column id="colunaMedia"
footerText="#{alunoAvaliacaoMB.getMediaAvaliacao(avaliacao.property)}"/>
</ui:repeat>
</p:row>
</p:columnGroup>
<p:dataTable>
The update doesn't occurs...
second way (based on this answer on SO: How to ajax update an item in the footer of a PrimeFaces dataTable?):
<p:remoteCommand name="refreshFooter" update=":form:dataTableAvaliacao:outputMediaAvaliacao"/>
<p:dataTable
id="dataTableAvaliacao" var="aluno"
value="#{alunoAvaliacaoMB.alunos}">
<p:column>
<p:inputText id="inputNota"
value="#{aluno.getNota(avaliacao.property).vlNotaString}">
<p:ajax event="change"
update=":form:dataTableAvaliacao:mediaAluno" oncomplete="refreshFooter();" />
</p:inputText>
</p:column>
<p:dataTable>
<f:facet name="footer">
<h:outputText colspan="1" value="Nota média da avaliação:"/>
<ui:repeat value="#{alunoAvaliacaoMB.colunasAvaliacoes}"
var="avaliacao">
<h:outputText id="outputMediaAvaliacao"
value="#{alunoAvaliacaoMB.getMediaAvaliacao(avaliacao.property)}"
</ui:repeat>
</f:facet>
I've also tried
<p:remoteCommand name="refreshFooter" update=":form:outputMediaAvaliacao"/>
If I put
<p:ajax event="change"
update=":form:dataTableAvaliacao:mediaAluno, :form:dataTableAvaliacao" />
in the first way, it works, but I don't wanna update all dataTable every time.
What I'm doing wrong? is it a bug?
Referring on 2nd way from your question that you based on this answer...
actually it is possible to update p:dataTable footer (even from within table itself)...but with one modification of your code.
Reason why your implementation does not work is that you did not take into account that <h:outputText id="outputMediaAvaliacao"../> is wrapped with ui:repeat.
In that case, p:remoteCommand is not able to find h:outputText component ID defined in update attribute because that ID does not exist in DOM:
ui:repeat is actually copying h:outputText as many times as list from value attribute is long and appending all parent IDs to newly created native HTML components
<span id="form:dataTableAvaliacao:avaliacao:0:outputMediaAvaliacao">...</span>
<span id="form:dataTableAvaliacao:avaliacao:1:outputMediaAvaliacao">...</span>
<span id="form:dataTableAvaliacao:avaliacao:2:outputMediaAvaliacao">...</span>
...
(you can see the same using DOM inspector of your favorite browser)
SOLUTION
After you learn and understand all facts stated above (like I did :) ), solution is quite simple:
wrap ui:repeat with some parent element and assign ID to parent element. For example like this
<f:facet name="footer">
<h:outputText value="Nota média da avaliação:"/>
<h:panelGroup id="footerPanel">
<ui:repeat value="#{alunoAvaliacaoMB.colunasAvaliacoes}"
var="avaliacao" id="avaliacao">
<h:outputText id="outputMediaAvaliacao" value="#{alunoAvaliacaoMB.getMediaAvaliacao(avaliacao.property)}" />
</ui:repeat>
</h:panelGroup>
</f:facet>
and modify p:ajax of p:inputText to update newly created element after text is changed
<p:ajax event="change" update=":form:dataTableAvaliacao:footerPanel" />
On this way all children elements of h:panelGroup will be updated (meaning only footer will be updated and not entire table).
And now, after you solved updating, you can focus on designing of all UI elements under h:panelGroup to make them fit your requirements.
I'm trying to help users fill in entity Id numbers on a submittal form. I can't use a pulldown because there are 1000's.
In a PF dialog, I'm able to copy a selected value to the main form but I'm hardcoding the actionaListener into the commandLink to tell the popup dialog which h:textInput box on the main form to copy the value to and to render. If I have three h:inputText boxes I would then need to duplicate three p:dialogs.
For example in my p:dialog I would have a column in the datatable as such:
<h:commandLink value="Select This Item" onclick="PF('dlg').hide()">
<f:ajax render=":myForm:text_field_1" event="click"
listener="#{bean.popDownId1(item.id)}" />
</h:commandLink>
How can I pass those variables myForm:text_field_1 (the form name and field) to the p:dialog so that it becomes a more generic popup dialog? Also is there a way to not have to code a listener method for each field (popDownId1, popDownId2, etc...)As a bonus I'd also like to externalize the dialog and include it in every xhtml page instead of cutting and pasting as I'm doing now.
Here is more actual code:
form.xhtml
<h:form id="myForm">
<h:panelGrid columns="3">
<p:outputLabel value="Manager Employee Number: " />
<h:panelGroup>
<p:inputText id="managerId"
title="Type Employee Id or click the ? to search for their Id"
value="#{bean.department.manager}" >
<f:validator validatorId="com.company.app.EmployeeIdValidator" />
</p:inputText>
<p:commandButton title="Click here if you don't know their Employee Number"
id="managerId" value="Lookup Id"
onclick="PF('dlgManager').show();" type="button" >
</p:commandButton>
other fields and submit button
</h:form>
<p:dialog id="popup" modal="false" widgetVar="dlgManager" dynamic="true" >
<f:facet name="header">
<h:outputText value="Employee Number Finder" />
</f:facet>
<p>Search using any keyword.</p>
<h:form>
Keyword: <p:inputText id="search" value="#{employeeSearch.searchString}" />
<p:commandButton value="Search"
action="#{employeeSearch.searchByKeyword}">
<f:ajax execute="#form" render="output" />
</p:commandButton> (Enter keywords separated by spaces)
<p:dataTable id="output" var="employee" value="#{employeeSearch.employees}">
<p:column headerText="Action">
<h:commandLink value="Select" onclick="PF('dlgManager').hide()">
<f:ajax render=":myForm:managerId" event="click"
listener="#{bean.popDownManagerId(employee.id)}" />
</h:commandLink>
</p:column>
other columns(employee name, phone number, etc...)
</p:dialog>
you can see that I'd need to copy the dialog and tweak it a bit for every field on my form where I want to do an employee number lookup.
onclick="PF('dlgManager').show();">
onclick="PF('dlgSupervisor').show();">
onclick="PF('dlgFloorChief').show();">
EDIT
When applying BalusC's answer, if I add a second lookup Id button, the popup dialog to select an employee id has a command link which is tied to only the ManagerId field
action="#{bean.popDownManagerId(employee.id)}"
Also, when the second lookup id button is pressed the previous search results are still listed so the select command link would be referencing the wrong field to update
popup dialog
I am working on a form which has two datatables. In the first datatable, I am displaying the radio buttons and checkboxes, whereas the second datatable contains
selectOneMenu(s). Value change listener has been implemented on the selectOneMenu and on value change, the subsequent fields gets populated based on the selection.
Everything works fine except that when I select the value from the dropdown, the checkbox and the radio button values are cleared.
f:ajax event="change" has been used for the change event on selectOneMenu. Looks like the whole page gets refreshed and the values are cleared.
I also tried using f:ajax by updating the id of the datatable in which the selectOneMenu is present.
<p:dataTable styleClass="borderless" id="inResultTable" var="result" value="#{RequestBean.fooFields}" rendered="#{not empty RequestBean.fooFields}">
<p:column style="width:150px;">
<f:facet name="header">
<h:outputText value=" " />
</f:facet>
<h:outputText value="#{msg[result.fldLabel]}" />
</p:column>
<p:column>
<f:facet name="header">
<h:outputText value="" />
</f:facet>
<ui:repeat value="#{RequestBean.fooFields}"
var="itm">
<h:selectOneMenu value="#{itm.indFieldValue}"
rendered="#{result.lvlid==itm.lvlid}"
style="width:250px;padding-right:150px;text-align: left;">
<f:selectItems value="#{RequestBean[itm.indField]}" />
</h:selectOneMenu>
<h:selectOneRadio value="#{itm.indFieldValue}" rendered="#{result.lvlid==itm.lvlid and result.fldType=='radio'}"
style="width:250px;padding-right:150px;text-align: left;">
<f:selectItems value="#{RequestBean[itm.indField]}" />
</h:selectOneRadio>
<h:selectManyCheckbox value="#{itm.indFieldCheckBox}" rendered="#{result.lvlid==itm.lvlid and result.fldType=='selectbox'}">
<f:selectItems value="#{RequestBean[itm.indField]}" />
</h:selectManyCheckbox>
</ui:repeat>
</p:column>
</p:dataTable>
<p:dataTable styleClass="borderless"
id="resultTable" var="result"
value="#{RequestBean.depFields}">
<h:selectOneMenu value="#{RequestBean.field4Value}"
valueChangeListener="#{RequestBean.processValueChange4}"
rendered="#{result.lvlid=='5' and result.fldType=='selectbox'}"
style="width:250px;padding-right:150px;text-align: left;">
<f:selectItem itemLabel="--Please Select--" itemValue="#{null}" />
<f:selectItems value="#{RequestBean[result.field]}" />
<f:ajax event="change" render="#form" />
</h:selectOneMenu>
...
...
</p:dataTable>
N.B: The requirement is such that the datatable with checkbox and radio buttons has to be placed at the top. IDs cannot be used for the selectOneMenu in the second table since I am
populating the selecOneMenu(s) dynamically based upon the entries in the database.
I know that this might be a simple issue but didn't have any luck with the info posted on most websites.
Any help would be appreciated.
Here's your <f:ajax>.
<f:ajax event="change" render="#form" />
You didn't specify the process attribute. So it defaults to #this, which means that only the current input component is processed during submit. However, you specified a render of the whole form. So the whole form will be refreshed. However, the other input components aren't been processed during submit. So their model values won't be updated, which means that during render response the initial values will be redisplayed instead of the submitted values, which are in your case apparently blank/null.
You've basically 2 options:
Process the whole form during submit.
<f:ajax process="#form" render="#form" />
Or, update only those components which really needs to be updated.
<f:ajax render="clientId1 clientId2 clientId3" />
In your particular case I think option 2 isn't viable, so option 1 is the best one. Please note that I omitted the event attribute. It defaults to change already.
Unrelated to the concrete problem, I'm not sure what you're all doing in your value change listener method, but I only want to note that most starters abuse it for the purpose of manipulating the model values and that it don't always work quite as expected (changed model values are not reflected at all). If this is true in your case, then you should actually be using <f:ajax listener> instead.
See also:
When to use valueChangeListener or f:ajax listener?
The main reason for the values of Check boxes & Radio buttons getting cleared after a value change listener could be that the model values are not updated.
Value change listeners are called before updating the model.
For these kind of issues, it is very important to have an understanding of the JSF lifecycle.
Please try following code in your value change listener and see.
public void valueChange(ValueChangeEvent event){
PhaseId phase = event.getPhaseId();
if (phase.equals(PhaseId.ANY_PHASE))
{
event.setPhaseId(PhaseId.UPDATE_MODEL_VALUES);
event.queue();
return;
}
if(!phase.equals(PhaseId.UPDATE_MODEL_VALUES))
{
return;
}
// Your code
}
I didn't try this code with your example. Please let me know with complete example source code if it is not working.
Thanks.
My requirement is like this: I am having a text input and whenever a value change event occurs, a select many list box has to be populated. If there is no matching records found, then a text input has to appear instead of a select many list box.
<h:column>
<h:selectManyListbox size="3" value="#{hostInfoBean.gateKeeperendPointReference}" rendered="#{hostInfoBean.selectManyRendered}" id="gateKeeperendPointReference">
<f:selectItems value="#{hostInfoBean.gateKeeperendPointReferenceItems}" />
</h:selectManyListbox>
<h:inputText id="gateKeeperendPointReferenceText" size="30" rendered="#{!hostInfoBean.selectManyRendered}">
</h:inputText>
</h:column>
Also I am using a4j for the value change listener,
<a4j:support event="onchange" reRender="hostInfo:gateKeeperendPointReference" focus="GFacPath"
ajaxSingle="true" />
'selectManyRendered' is a boolean value which I am determining in the JAVA bean. The program works only for the default value of the boolean variable. If the boolean value is changed during runtime, then the toggle between the visibility of selectManyListbox and inputText is not working. Please help to fix this. Am i missing something?

Suresh
If the "rendered" attribute resolves to false, then the component isn't in your tree and can't be found as a "rerender" target. When you have components that are rendered conditionally you want to wrap them in a component that is always available as a target, like so:
<h:inputText value="#{myBean.text}" >
<a4j:support event="onkeyup" reRender="listZone" ajaxSingle="true" />
</h:inputText>
<h:panelGroup id="listZone">
<h:selectManyListbox value="#{myBean.list}" rendered="#{myBean.renderList}" >
<f:selectItems value="#{myBean.listItems}" />
</h:selectManyListbox>
<h:inputText size="30" rendered="#{!myBean.renderList}/>
<h:panelGroup id="listZone">
