I am looking for solution that p:overlayPanel content should update it self while clicking commendButton or commendLink. But its showing blank white p:overlayPanel when i click the button. The updating with the p:overlayPanel id in that button or link. I have tried many ways nothing worked out. Is my code wrong?
Please suggest some solution.
Here is my code :
<ui:repeat id="profiles" value="#{items.lstProfiles}" var="profile">
<p:commandLink id="profileLink" value="show" update="moviePanel"
actionListener="#{dashBoardController.showProfileOverlay}"/>
<p:overlayPanel id="moviePanel" for="profileLink" hideEffect="fade"
dynamic="true" style="width:300px; height: 150px;">
<h:panelGrid columns="2">
<h:outputText value="Name : "/>
<h:outputText value="#{dashBoardController.selectedProfile.name}"/>
</h:panelGrid>
</p:overlayPanel>
</ui:repeat>
Usually dynamic="true" should do the job but some times it fails.So to update the contents inside the Overlay.
There are many ways to do this by tweaking Jquery.
Simplest one I can think of is:
Since ui:repeat generates dynamic ID for p:overlayPanels you can update by providing unique css class name from every iteration.
In Primefaces you can select a component using css class also using: #(.myclass).
And so you can update that component also:- update="#(.mystyle)"
Example:
<h:form>
<ui:repeat var="patient" value="#{dataCenter.patientList}">
<p:commandLink value="#{patient.firstName}" id="patientNameLnk" update="#(.overlay-class-#{patient.patientId})"/><br/>
<p:overlayPanel for="patientNameLnk">
<h:panelGroup styleClass="overlay-class-#{patient.patientId}">
#{patient.firstName}
#{patient.lastName}
#{patient.dob}
</h:panelGroup>
</p:overlayPanel>
</ui:repeat>
</h:form>
In the above example css class name for every h:panelGroup will be generated as overlay-class-<PATIENT_ID> so every h:panelGroup will have unique class name(if patientId is unique).
Note: Note that I'm updating h:panelGroup inside p:overlayPanel because if you update p:overlayPanel then it might start flickering(it happened to me while executing above example).
I'm using RichFaces with JSF to develop a simple app. One page of this app contains several collapsiblePanel elements. Some of the collapsiblePanel elements are nested, but never more than a second layer.
I would like to provide links or buttons on the page to expand all and collapse all collapsiblePanel elements on the page. How can I do that?
The elements currently use the switchType="client" attribute to let the client handle the expanding and collapsing. I suspect that using a type of ajax instead may help, but I'm not sure nor do I know how I would take advantage of it.
Update: My question may be easier to understand if I include an example of what I'm trying to do:
<h:form>
<a4j:commandButton actionListener="#{bean.setDefaultExpanded(true)}"
render="reportPanel" value="Expand all" />
<a4j:commandButton actionListener="#{bean.setDefaultExpanded(false)}"
render="reportPanel" value="Collapse all" />
<h:panelGrid id="reportPanel">
<ui:repeat var="account" value="#{bean.results.entrySet().toArray()}">
<rich:collapsiblePanel expanded="#{bean.defaultExpanded}">
<ui:repeat var="chargeGroup" value="#{account.value.entrySet().toArray()}">
<rich:collapsiblePanel expanded="#{bean.defaultExpanded}">
<h:outputText value="content: #{chargeGroup.value}" />
</rich:collapsiblePanel>
</ui:repeat>
</rich:collapsiblePanel>
</ui:repeat>
</h:panelGrid>
</h:form>
The <rich:collapsiblePanel> has the expanded attribute, you can bind it to bean property and control the expansion from there. Something like this
<rich:collapsiblePanel id="panel1" expanded="#{bean.expanded}" …>
<a4j:commandButton actionListener="#{bean.togglePanels()}"
… render="panel1, panel2, …"/>
The switchType controls where the content is pulled from, not how you expand/collapse the panel.
I had the same problem when click individual panels and then expand/collapse all. This work for me (richfaces 4.2.3):
<h:commandButton immediate="true" action="#{controllerBean.toggleMin}" value="collapse all" >
<a4j:ajax render="panel1 panel2"></a4j:ajax>
</h:commandButton>
<h:commandButton immediate="true" action="#{controllerBean.toggleMax}" value="expand all">
<a4j:ajax render="panel1 panel2"></a4j:ajax>
</h:commandButton>
...
<rich:collapsiblePanel id="panel1" immediate="true" expanded="#{modelBean.expanded}" header="Title text" switchType="client">
...
</rich:collapsiblePanel>
...
I have a datatable from which I open with a click on an image the <rich:modalPanel>. But the <rich:componentControl for="panel" attachTo="showPreview" must have the exact id, in my case below: showPreview, but as my link is inside a dataTable, it will be generated like 1:showPreview 2:showPreview.....n:showPreview
Is there any way to know in which line of the table i am, to get a dynamic binding?
My XHTML in JSF 1.2 looks something like this:
<h:dataTable styleClass="tb_tabletag" id="dtContentPosts" value="#{listOfObjects}" var="object">
<h:column id="columnnumber" >
<h:outputLink id="showPreview" value="#">
<h:graphicImage value="preview.png" />
<rich:componentControl for="panel" attachTo="showPreview" operation="show"
event="onclick"/>
</h:outputLink>
</h:column>
</h:dataTable>
...
...
...
<rich:modalPanel id="panel" autosized="true">
some stuff
</rich:modalPanel>
Thank you for any help!
Thanks Luiggi for your link, with the given source code,this helped me to find my simple trick:
i get now the number with: #{listOfObjects.indexOf(object)}
the only important thing is, that the modalPanel is in a <h:column></h:column> to receive the correct number
works perfect
I have a problem are that when I try update a component that not are in same xhtml.
Somebody know how to do?
thx
PD: im using primefaces 3.2
Sorry for my english
I think that I dnot explain very well.
I have a xhtml father with tis structure:
<h:panelGrid id="tabla">
<h:form id="formTripu" prependId="false">
<h:panelGrid id="fichaTripulante">
<ui:include src="path1" />
<p:spacer height="5px" />
<p:tabView dynamic="false" cache="true">
<p:tab title="#{bundleTrip.datosAdministrativos}">
<ui:include
src="path2" />
</p:tab>
<p:tab title="Datos Operativos ">
<ui:include
src="path3" />
</p:tab>
I wish to do are when for example in path1 I use a h:selectBooleanCheckbox like:
<h:selectBooleanCheckbox inmediate="true" id="checkExt"
value="#{bean.Obj.field}">
<f:ajax render="estadoTripu"
actionListener="#{bean.method}" />
</h:selectBooleanCheckbox>
estadoTripu are in path2 (otherxthml but in same form).
<p:panel>
<h:panelGrid id="datos" columns="5">
<p:column>
<h:selectOneMenu id="estadoTripu"
value="#{bean.Obj.Field2}">
<f:selectItems
value="#{bean.list}" var="item"
itemValue="#{item.id}" immediate="true"
itemLabel="#{item.desc}">
</f:selectItems>
</h:selectOneMenu>
</h:panelGrid>
</p:column>
</h:panelGrid>
</p:panel>
Witch is paht in render o f:ajax????
thx everyone
try this: (Its a trick I learned from BalusC :) )
add binding="#{components.mySelecOneMenu}" to your h:selectOneMenu
<h:selectOneMenu binding="#{components.mySelecOneMenu}" .....
This how you button should look like (more or less)
<h:commandButton value="doSomeThing">
<f:ajax render="#{components.mySelecOneMenu.clientId}"/>
</<h:commandButton>
add this to your faces-config.xml
<managed-bean>
<description>Holder of all component bindings.</description>
<managed-bean-name>components</managed-bean-name>
<managed-bean-class>java.util.HashMap</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
</managed-bean>
Here some detailed explanation of what I just recommend you to do
How do I break the tyranny of the clientID?
JSF component binding without bean property
if they are not in the same xhtml, do you include one in the other? If not, just change page and it will show the correct one.
But I don't think I correctly understand your question.
Add some code please
I find that component should be in same form an call ids start in form to component, its prefered put id every panelgrid, panel, etc because you have to call every component englobe comoponent that you want render.
I would like to be able to conditionally omit a footer from a PrimeFaces panel element:
<p:panel header="some text">
<f:facet name="footer">
#{message}
</f:facet>
<!-- ... -->
</p:panel>
I hoped that the rendered attribute would work:
<p:panel header="some text">
<f:facet name="footer" rendered="#{!empty message}">
#{message}
</f:facet>
<!-- ... -->
</p:panel>
But the footer is still rendered, with empty content. It appears that facet does not have the rendered attribute: http://www.jsftoolbox.com/documentation/help/12-TagReference/core/f_facet.html.
What's the right way to do this?
I was able to solve this by swapping the facet out for an attribute. To summarize:
This works
<p:panel ...>
<f:attribute name="footer" value="#{message}"/>
<!-- ... -->
</p:panel>
But this doesn't work
<p:panel footer="#{message}">
<!-- ... -->
</p:panel>
Neither does this
<p:panel ...>
<f:facet name="footer">#{message}</f:facet>
<!-- ... -->
</p:panel>
Nor this
<p:panel ...>
<f:facet name="footer">
<h:outputText value="#{message}" rendered="#{!empty message}"/>
</f:facet>
<!-- ... -->
</p:panel>
by "works" I mean:
"renders no footer — not just an empty footer — when #{message} is empty or null; otherwise, correctly renders the footer with the specified text."
PrimeFaces forum thread on this issue
You could declare a ui:param and let the template check the param while renderring.
The facet in the template could then be declared as:
<f:facet name="#{hideFooter == null or not hideFooter ? 'footer' : ''}">
#{message}
</f:facet>
Any page can then declare this param
<ui:param name='hideFooter' value='#{some rule}' />
and set the appropriate rule for the param. For any page that does not declare the param, the footer will be displayed.
Here's what I did in trying to conditionally render a facet within a composite component.
<composite:interface>
<composite:facet name="header" required="false" />
</composite:interface>
<composite:implementation>
<p:panel>
<c:if test="#{empty component.facets.header}" >
<f:facet id="#{cc.attrs.id}_default_header" name="header">
all sorts of stuff here
</f:facet>
</c:if>
<c:if test="#{not empty component.facets.header}">
<composite:insertFacet id="#{cc.attrs.id}_custom_header" name="header" />
</c:if>
<composite:insertChildren id="#{cc.attrs.id}_content"/>
</p:panel>
</composite:implementation>
This let's the user of the composite component supply the header facet if they want, and if they don't, we supply a default. Obviously, instead of providing a default, you could simply not do anything.
This mixes c:if in jsf controls, but we didn't see any adverse effects.
I have come across a similar issue with plain JSF. I am not sure how a <p:panel> is rendered, but if it is rendered as a table, you can try this:
First, declare a CSS-class like this:
.HideFooter tfoot {
display: none;
}
Then set that class conditionally on the panel:
<p:panel styleClass="#{renderFooterCondition ? null : 'HideFooter'}">
The footer is still rendered in the JSF-sense, but it is not displayed and does not take up any space in the page when viewed by the user-agent.
I successfully solved this problem using ui:fragment
<ui:fragment rendered="...Test...">
<f:facet name="footer">
...
</f:facet>
</ui:fragment>
works for example to conditionnaly render the footer of a primefaces datatable (the rendered attribute of the facet does not work).
Not sure how well this would work for your footer, but I had the same issue with a legend I was trying to conditionally render. I fixed it by using the rendered on anything inside the facet tag.
<p:fieldset>
<f:facet name="legend">
<h:outputText value="#{header1}" rendered="#{header1.exists}"/>
<h:outputText value="#{header2}" rendered="#{not header1.exists}"/>
</f:facet>
content
</p:fieldset>
I had difficulty trying c:if with my ui:repeat, so this was my solution. Not quite the same as your problem, but similar.
Facets are not intended to render HTML, which is why it doesn't have the rendered attribute. Facets add functionality to a page. The term facet is probably a poor choice of name. It's very ambiguous.
..if the list compiled by ITworld's Phil Johnson has it right, the
single hardest thing developers do is name things.
ie.
JSF facets
A project facet is a specific unit of functionality that you can add to a project when that functionality is required. When a project facet is added to a project, it can add natures, builders, classpath entries, and resources to a project, depending on the characteristics of the particular project. JSF facets define the characteristics of your JSF enabled web application. The JSF facets specify the requirements and constraints that apply to your JSF project.
The JSF facets supply a set behaviors and capabilities to your web application.
This is a counter-answer to the answer from Ludovic Pénet.
This worked for me in <f:facet name="footer"> in selected p:column items of a p:dataTable (Primefaces 5.3):
...
Note how I have the ui:fragment inside the f:facet, not outside (not wrapping) it. It definitely completely removes the entire row when every footer facet is tested to NOT render (as far as I can tell, independent of the content within the ui:fragment).
Try with this, from primefaces web page
<p:columnGroup type="footer">
<p:row>
<p:column colspan="3" style="text-align:right" footerText="Totals:" />
<p:column footerText="your value in ajax" />
<p:column footerText="your value in ajax" />
</p:row>
</p:columnGroup>

For those who landed here trying to hide the footer, instead of header, but the syntax component.facets.footer didn't work, should try this:
<p:panel id="panelContent">
<c:if test="#{not empty cc.facets.footer}">
<f:facet name="footer" height="100%">
your content
</f:facet>
</c:if>
</panel>
Why don't you enclose the content of the footer into a panelGroup which has the rendered attribute?
This way:
<p:panel header="some text">
<f:facet name="footer">
<h:panelGroup rendered="#{!empty message}">
#{message}
</h:panelGroup>
</f:facet>
<!-- ... -->
</p:panel>
I do it in my weapp and it works, no footer is rendered.
I don't use primefaces though, I do it with h:datatable, but I think that it must works with p:panel too.
I try this solution and ok. (http://www.coderanch.com/t/431222/JSF/java/dynamically-set-panel-header-condition)
<rich:dataGrid value="#{myMB.student.list}" rendered="#{!empty myMB.student and !empty myMB.student.list}" var="st" rowKeyVar="row">
<rich:panel>
<f:facet name="header">
<h:panelGroup id="panelHeader">
<h:outputText value="Just one student" id="header1" required="true" rendered="#{!myMB.manyStudents}"/>
<h:outputText value="#{row+1}º Student" id="header2" required="true" rendered="#{myMB.manyStudents}"/>
</h:panelGroup>
</f:facet>
<rich:panel>
