Let say that I want to create a variable set of <rich:tab> elements within a <rich:tabPanel> component. So I tried to do that way:
<rich:tabPanel switchType="client" ...>
<ui:repeat value="#{myBean.myTabs}" var="tab">
<rich:tab name="#{tab.name}" label="#{tab.label}"/>
</ui:repeat>
</rich:tabPanel>
But it didn't work, as no tab is rendered. I also got the following message in the logs:
j_id174: tab panel has no enabled or rendered tabs!
This problem seems to be encountered by others people, for example here.
So as suggested by the previous thread, I replaced my <ui:repeat> by a <c:forEach> but the problem still occurs.
I have a way to solve this problem using the binding attribute of my <rich:tabPanel> component:
<rich:tabPanel switchType="client" binding="#{tabNavigationBean.tabPanel}"
</rich:tabPanel>
and then in my Java bean:
private HtmlTabPanel tabPanel; // + getter and setter
public void setTabPanel(HtmlTabPanel tabPanel) {
this.tabPanel = tabPanel;
if (tabPanel != null) {
createTabs();
}
}
private void createTabs() {
Application application = FacesContext.getCurrentInstance().getApplication();
HtmlTab newTab = null;
for (DedicatedPageTab dpt : getDedicatedPageTabs()) {
newTab = (HtmlTab) application.createComponent(HtmlTab.COMPONENT_TYPE);
newTab.setLabel(dpt.getLabel());
newTab.setName(dpt.getName());
tabPanel.getChildren().add(newTab);
}
}
This code is working.
However, my question is to know if I can solve my problem without using the binding attribute (i.e. a 100% pure XHTML solution)?
<a4j:outputPanel id="out">
<rich:tabPanel>
<c:forEach items="list" var="var">
<rich:tab label="#{var.name}" switchType="client">
content
</rich:tab>
</c:forEach>
</rich:tabPanel>
</a4j:outputPanel>
Yes, it is possible, but difficult. Here are some notes I have:
Use c:forEach to create tab tags inside tabPanel inside outputPanel. reRender outputPanel on tab removal, add, or name change

I'm using p:button with onclick action. (I can't move to p:commandButton, because of legacy outcome navigation in faces-config.xml and custom navigation history in db):
<p:remoteCommand name="unlock_tt" actionListener="#{ttEntityMBean.unlock()}"/>
<p:button value="#{msgs['button.ok']}" outcome="#{ttEntityMBean.navigationMenuItemToRedirect.navigationRule}" onclick="unlock_tt()"/>
Generated by primefaces javascript looks like
onclick="unlock_tt(); window.open(....)"
And after clicking button, unlock_tt() in browser initiated, but immediatly broken by page redirecting, so backed java method didn't execute.
Should I make unlock_tt() or java call async to be sure it will be executed before browser leaves page?
Upd: I'm thinking to use p:commandButton, if it is possible to get to-view-id programically, like in this question:
Programmatically get navigation case <to-view-id> from faces-config.xml by outcome
<p:commandButton action="#{ttEntityBean.unlock()}"/>
public String unlock() {
//some business logic
return OutcomeResolverHelper.getRuleFor(navigationMenuItemToRedirect.navigationRule)
}
This should reduce number of requests
I'm not sure this will work but can you try this :
Instead of :
<p:remoteCommand name="unlock_tt" actionListener="#{ttEntityMBean.unlock()}"/>
<p:button value="#{msgs['button.ok']}" outcome="#{ttEntityMBean.navigationMenuItemToRedirect.navigationRule}" onclick="unlock_tt()"/>
do:
<h:panelGroup>
<f:ajax event="click" listener="#{ttEntityMBean.unlock}"/>
<p:button value="#{msgs['button.ok']}" outcome="#{ttEntityMBean.navigationMenuItemToRedirect.navigationRule}" />
<h:panelGroup>
Don't forget to remove onclick and your remotecommand.
This should wrap a panelGroup around your button. PanelGroup implements ClientBehaviorHolder so it can get f:ajax tag in its children. Thus when you click on it it should trigger the listener.
The easiest way was migration from p:button to p:commandButton, which allows to execute some java-code in action method before redirect. The core is programmical translation of navigation rule, defined in faces-config.xml to base url, usable in explisit jsf-2.0 style:
//receive base url from <to-view-id> tag
public static String resolveOutcomeRule(String ruleName) {
FacesContext context = FacesContext.getCurrentInstance();
ConfigurableNavigationHandler configNavHandler = (ConfigurableNavigationHandler)context.getApplication().getNavigationHandler();
NavigationCase navCase = configNavHandler.getNavigationCase(context, null, ruleName);
return navCase.getToViewId(context);
}
//decorate it with faces-redirect=true and our custom navigation
public static String resolveOutcome(NavigationMenuItem item) {
return resolveOutcomeRule(item.getNavigationRule()) + "?faces-redirect=true&menu=" + item.getId();
}
//controller-method
public String cancelEditTT() {
super.unlock();
return FacesUtil.resolveOutcome(getNavigationMenuItemToRedirect());
}
//new jsf button:
<p:commandButton value="#{msgs['button.ok']}" action="#{ttEntityMBean.cancelEditTT}"/>
This solution provided 1-step redirect instead of 2-step old one.
I am relatively new in jsf.
I have a jsf page someDetails.xhtml, in which I have an output link
<h:outputLink value="#{someTaskController.completeTask(taskId)}?taskId=#{taskId}">Assign Ticket</h:outputLink>
On clicking on this link, the method completeTask should be called and do something.
The problem is, when the jsf page someDetails.xhtml is opened(in browser), the method completeTask is getting called and does all the task, which should only happen on clicking the link.
What should I do ? Please help
You're using the wrong tag for your purpose, use command link instead:
<h:commandLink value="Assign Ticket" action="#{someTaskController.completeTask()}">
<f:param name="taskId" value="#{taskId}" />
</h:commandLink>
You can access taskId inside method completeTask() like this:
public void completeTask() {
Map<String,String> params =
FacesContext.getExternalContext().getRequestParameterMap();
String taskId= params.get("taskId");
// do your business action...
}
I'm in the middle of building a web application (Spring 4, Primefaces 5.1 and JPA).
While one of my xhtml-pages has no problems working with its ManagedBean, the others won't really work. To be more specific, the UI input components (like inputText) won't call any setters from the managed Beans.
I've already run my Tomcat (8) on debug mode, which showed me that the page calls the get-methods, but no set-methods at all. If I try to persist something, all values are null (or 0, in case of an int-value). (it even persists an object into the database with all values null, though I have declared some #NotNull constraints which should be taken to the database configuration via JPA)
So, question is: How can I make my inputFields work with the fields of my ManagedBean? (Eclipse also shows me in the editor, that theoretically, the connection to the fields is there, it knows the managed bean, the field and the get-/set-methods)
SoftwareManagedBean.java
#ManagedBean(name = "swmb")
#ViewScoped
public class SoftwareManagedBean extends AssetManagedBean implements
Serializable {
private String bezeichnung;
private Software neueSoftware;
// +some more private fields, every single one with its get-/set-method
#Override
public String getBezeichnung() {
return super.getBezeichnung();
}
#Override
public void setBezeichnung(final String bezeichnung) {
super.setBezeichnung(bezeichnung);
}
//instantiante the field "neueSoftware"
public void createEmptySoftware(){
if(neueSoftware != null)
return;
this.neueSoftware = new Software();
}
//Persist Software with values from inputFields
public void addSoftware() {
createEmptySoftware();
neueSoftware.setBezeichnung(getBezeichnung());
softwareService.addSoftware(neueSoftware);
//...
neueSoftware = null;
}
viewSoftware.xhtml
<h:body>
<p:dialog header="Neue Software anlegen" widgetVar="SwNeuDialog" width="60%"
closeOnEscape="true" draggable="false" resizable="false" position="center">
<h:form id="SwDlgForm">
<h:panelGrid columns="3" border="0" >
<p:outputLabel for="swBezeichnung" value="Bezeichnung: " />
<p:inputText id="swBezeichnung" value="#{swmb.bezeichnung}"
label="Bezeichnung" required="true" />
<f:verbatim/>
<p:outputLabel for="swKategorie" value="Kategorie: " />
<p:selectOneMenu id="swKategorie" value="#{swmb.kategorie}" label="Kategorie" required="true" >
<f:selectItem itemLabel="Kategorie wählen" value="#{null}" noSelectionOption="true"/>
<f:selectItems value="#{swmb.kategorieListe}" var="kat" itemLabel="#{kat.bezeichnung}" itemValue="#{kat}"/>
</p:selectOneMenu>
<p:commandButton value="neue Kategorie hinzufügen" />
<!-- + some more input fields -->
<p:commandButton value="Speichern" action="#{swmb.addSoftware()}" onclick="PF('SwNeuDialog').hide()" resetValues="true" process="#this"/>
<p:commandButton value="Abbrechen" onclick="PF('SwNeuDialog').hide()" resetValues="true" process="#this"/>
</h:panelGrid>
</h:form>
</p:dialog>
<!-- dataTable -->
</h:body>
AssetManagedBean.java
#ManagedBean
public abstract class AssetManagedBean {
//name of the hard-/software
private String bezeichnung;
//+ some more fields with get-/set methods
public String getBezeichnung() {
return bezeichnung;
}
public void setBezeichnung(String bezeichnung) {
this.bezeichnung = bezeichnung;
}
I hope that code is sufficient to see the problem, since the rest of the code follows the same structure. I think, the problem could lie within the xhtml file, but I don't see where or why. I've got the SpringBeanFacesELResolver (or however it is called), I've already looked through the code and compared it to another xhtml page and its Managed Bean, but there are no differences anymore. (though one is working, one not)
My debugger showed, how the working class/page (viewAdministration.xhtml) called the get-/set methods of the managed bean:
opening dialog window: get...(), set...()
clicking the commandButton to submit/persist: get() (old Value), set() (new Value), get() (new Value)
Another get() (called by the add... method)
(+ another get() for the dataTable on the main page)
on viewSoftware.xhtml, it looks like this:
opening dialog window: get()
clicking the commandButton to submit/persist:
another get() called by the addSoftware method
As you can see, when I try to submit, there is no set or get.
So, to summarize:
no setter called by trying to submit
the code on viewSoftware.xhtml and SoftwareManagedBean is similar to another, functioning ManagedBean + xhtml page (I've compared it again and again)
annotations in Managed Beans are the same (#ManagedBean, #ViewScoped)
the inputFields are inside a form (
I'm totally clueless, but I think it is some small mistake from my side that I can't just see.
I've searched through the web and especially stackoverflow, but all the problems and answers I've found couldn't help me finding what's wrong
Even without inheriting from a superclass it won't work (tried that out too)
I hope, you can help me. If this post is lacking some information, I'm sorry about that, I tried my best to not let this post grow too big and still get as much relevant information in it as possible.
So, I have found my mistake (or at least, I think I have). Only took me 2 weeks, but anyway...
I tried to test it out more specifically, wrote test classes and an xhtml page. Nothing worked (from simple Input over Dates to own classes).
The solution to this problem was to disable ajax on my commandButton (ajax="false"). When I tried to understand more of it, I realized that the commandButton opening the dialog window was nested in a facet inside a dataTable, and thus it had problems to properly set the values of the input fields.
So, thank you for your help. Maybe/hopefully this can or will help some other people later as well.
From the first glance at the code, without reading it whole, try putting process="SwDlgForm" on your command buttons, instead of process="#this". If that doesn't solve the problem, I'll read more carefully and try to help.
The calendar component gets hidden behind the accordion item, no matter what z-index value you assign to the component, be it for accordion/calendar it simply won't budge, can some one help me on this. I'm using RichFaces 4.2.0.
Sample code:
<h:form>
<rich:accordion style="z-index:10;" id="acrdion" switchType="client">
<rich:accordionItem id="acdItm" header="Overview:">
<rich:calendar value="#{bean.date}" datePattern="dd/M/yy"
id="Cal1" style="z-index:100;"/>
</rich:accordionItem>
</rich:accordion>
<h:form>
You can workaround this issue by overriding the rf-ac-itm-cnt class as follows:
<h:outputStylesheet>
.rf-ac-itm-cnt {
overflow: visible;
}
</h:outputStylesheet>
I'am using JSF/PF anf I can't make a graphicImage work. Reviewing the tons of topics published on forums, this PF's graphicImage seems to be so tricky. I am obviously doing somethig wrong, but, as long as I am replicating code that worked for others (see post), it must be something in the environment of the component. I hope to find a solution here, i'm stuck for weeks. Thanks
Here is my original question in PF forum:
I encounter a problem rendering the image. I have followed the code explained and I correctly retrieve the id for image to display in a separate method:
public StreamedContent getStreamedImage() {
StreamedContent streamedImage = null;
UIViewRoot uiRoot = FacesContext.getCurrentInstance().getViewRoot();
System.out.println(uiRoot.getClientId());
UIComponent component = FacesContext.getCurrentInstance().getViewRoot().findComponent("itemDataForm:imagesTbl:itemImgComp");
Map attributes = component.getAttributes();
Integer image_id = (Integer)attributes.get("item_img_id");
if(image_id != null && editionItem != null && editionItem.getImages() != null){
for(ItemImageView img : editionItem.getImages()){
if(image_id.intValue() == img.getId()){
streamedImage = new DefaultStreamedContent(new ByteArrayInputStream(img.getImage()), "image/jpeg");
}
}
}else{
streamedImage = new DefaultStreamedContent(new ByteArrayInputStream(editionItem.getImages().get(0).getImage()), "image/jpeg");
}
.......
I could't manage to retrieve the (always null) so I tried with attribute and it works. So, the DefaultStreamContent is loaded, by the image doesn't render at all. My code for xhtml:
<p:dataTable id="imagesTbl" var="itemImg" value="#{itemEditionBean.editionItem.images}">
<p:column>
<h:panelGrid columns="1">
<h:outputText value="#{itemImg.id}"/>
<p:graphicImage id="itemImgComp" value="#{itemEditionBean.streamedImage}">
<f:attribute name="item_img_id" value="#{itemImg.id}"/>
</p:graphicImage>
</h:panelGrid>
</p:column>
</p:dataTable>
Exactly the same that the code working in this topic above. PS: I have mt dataTable enclosed within a tab. Maybe a dependency on the enclosing component, or form, or what?
There is a huge amount of code from other related topics that can be viewed in the link below:
http://forum.primefaces.org/viewtopic.php?f=3&t=4163&p=39751
Based on another page I found on building dynamic images, <f:param .../> should be used to supply a parameter to the getStreamedImage() method rather than <f:attribute .../>. Are you using a ConversationScoped backing bean? I was having the same problem displaying dynamic images, but found that there is a problem using them with ConversationScoped beans. I switched my backing bean to Session scope and now it works fine.
