I am creating a mock-up using PrimeFaces 5.1. The sortBy feature is throwing up a NPE. Tracing the stack lets me believe that initially it needs a default sortBy attribute at the datatable level. Here's the XHTML. Did anyone manage to use the sortyBy feature of PrimeFaces 5.1 datatable?

Simply put "h:form" element was missing. That's all.

Below is my code for my file upload page and I can't figure out why when the upload is done it doesn't update my datatable with if the upload was successful or not. I could do a like a do not render til after update but don't think that is supported with the fileupload command. I did a system out on my list and it does have the values in it so the list is fully populated and ready to display but my datatable isn't showing anything? Am I missing something?

Edit: After a bunch of testing and code rewriting I have got it partially working but it seems like it doesn't like to render in my template code... So I was wondering if there may be something wrong in my template code.
Template code:

After a bunch of testing and deleting and rewriting like all my code I have figured out it was a stupid error with layouts and the <f:view> so I removed that and
<p:ajaxStatus onstart="statusDialog.show();"
onsuccess="statusDialog.hide();" />
And everything seemed to work fine!
I am new here :)
I have got a problem with one of my first web-apps written using JSF.
I wrote a simple template, it looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html
PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<p:layoutUnit position="west" header="West - menu" style="font-size: 15px;">
<h:form>
<ui:include src="menu.xhtml"/>
</h:form>
</p:layoutUnit>
<p:layoutUnit position="center" header="Center - content" style="font-size: 15px;">
<h:form id="contentForm">

</p:layoutUnit>

And in another file (obrazek.xhtml) I wrote this code:
<?xml version="1.0" encoding="UTF-8"?>

</p:panelGrid>
</h:form>
</ui:define>
</ui:composition>
</h:body>
</html>
I wanted to insert some code into "content" primefaces layoutUnit.
IDEA: It has to be 2 pictures and if I click on one of them, AJAX should show the value from ManagedBean using h:outputText. (it always adds +1 to the value :))
The problem is: if I dont add templating** into obrazek.xhtml everything works fine, but if I add:
<ui:composition template="template.xhtml">
<ui:define name="content">
CODE FROM FORM "PHOTOS" (the one about I called upper that "is no templated"**)
</ui:define>
</ui:composition>
while I am clicking on some picture nothing happens. Just "#" is added to my URL and it looks like that:
http://localhost:8080/obrazek.xhtml#
And my ManagedBean also:
#ManagedBean(name = "pic", eager = true)
#SessionScoped
public class PictureBean {
private int val1;
private int val2;
public void addValue1(){
val1 += 1;
}
public void addValue2(){
val2 += 1;
}
GETTERS AND SETTERS FOR VAL1 VAL2
}
I have rummaged all the web looking for the answer but uselessly.
Could anyone here help me? :)
Pardon for so long post and not coloured syntax, have to figure out "how to" do it, first :D
I have spring integrated with JSF and I am facing a strange behavior:
I hit the command button the action method in the managed bean is hit successfully (I removed it in the below example).
The Ajax update works perfect and the form is updated.
I hit another button the action method now in the managed bean isn't hit.
The panel is restored to the initial view and it freezes on this view.
I can't get the form updated except if I refresh the page and these steps are repeated.

Update:
I created a very simple single page and I noticed that when I remove the <h:head></h:head> tags the ajax works like a charm BUT without the fancy primefaces UI, and when I add the tags the ajax stop (this is normal cause <h:head></h:head> tags fetch all the needed JSs and CSSs), What Can I Do?

My Environment
Primefaces:3.5
JSF-Mojarra:2.2
Spring:3.2.3.RELEASE
In case anyone faces the same issue. I noticed that the Primefaces showcase is using JSF-Mojarra-2.1.22. I downgraded my JSF-Mojarra version from 2.2 to 2.1.22 and it worked like a charm.
If I am not wrong, I guess it should be reported to primefaces (if it isn't a current issue).
I defined a composite component (actually a few) and when I try to re-render a component inserted with I get the error mentioned:
<f:ajax> contains an unknown id ':contentFrm' - cannot locate it in the context of the component j_idt40
If I simply replace:
<et:pageContent formId="contentFrm">
with
<h:form id="contentFrm">
<div>
then everything works fine
Here is the relevant code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"

<h:form id="#{cc.attrs.formId}">
<div class="#{cc.attrs.styleClass}">
<composite:insertChildren/>
</div>
</h:form>
</composite:implementation>
</html>
This is how I use the composite

Some more tests.. using same component get's the same result.. for example the following code gives similar error (even replacing render="accountSummaryLines" with render=":accountSummaryLines")..

<f:ajax render="accountSummaryLines" />
</h:commandButton>
</et:div>
</et:pageContent>
</ui:define>
</ui:composition>
The only way I got this particular example working is using render="#form" like so..
It cannot be found because the composite component is by itself a NamingContainer. The real valid client ID would be :idOfComposite:contentFrm where idOfComposite is the (auto)generated ID of the composite component itself. If you do a View Source in webbrowser and locate the <form> in question, then you'll see it.
You need to give the composite component a fixed ID
<et:pageContent id="contentFrm">
and use exactly this ID on a plain HTML element which wraps the composite's content, e.g. <div> or <span>.
<composite:implementation>
<div id="#{cc.id}">
<h:form>
<div class="#{cc.attrs.styleClass}">
<composite:insertChildren/>
</div>
</h:form>
</div>
</composite:implementation>
We have a list to be displayed under a panel of the screen where all the code in which the fields are repeatable are kept under a different Facelet file. While I am trying to render an image based on the listener's action for an ajax event I am getting some problem to update the image with ID as JSF is generating an ID with the index in the middle due to the use of <ui:repeat> like so repeatForm:repeat:2:redimage.
This is the main page:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

</p:panel>
</ui:repeat>
</h:form>
</h:body>
</html>
This Facelet is repeatable based on the list size within the panel.
MyScreen.xhtml this is the include Facelet file:

<h:panelGroup style="display:block;text-align:left;width: 320px">

<h:outputText value="#{label.primaryCov}" />
</h:panelGroup>
<h:panelGroup style="display:block;text-align:left;width: 240px">
<h:selectBooleanCheckbox value="#{repeatListVar.abcInd1}" />
<h:outputText value="#{label.commGenLiab}" />
</h:panelGroup>
<h:panelGroup style="display:block;text-align:left;width: 180px">
<h:outputText value=" #{label.eachOccur}" style="text-align:left" />
</h:panelGroup>
<h:panelGroup style="display:block;text-align:left;width: 130px">
<p:inputMask mask="#{label.limitAmtMask}" id="genLiabEachOccAmt"
value="#{repeatListVar.a25GLEOAmt}" required="true"
style="width: 90px">

</p:inputMask>
<h:graphicImage id="redimage" url="/images/icons/redIcon.png" rendered="#{repeatListVar.testA25GLEOAmtInd}" />
</h:panelGroup>
This ends up generating IDs for the <h:outputText> that look like: repeatForm:repeat:2:redimage. But because we're using the <f:ajax> tag, we only need to specify "redimage". The tag takes care of the work of finding out what the real ID is.
We are calling a method in the listener and set the value of boolean indicator to either true or false which is false by default. The indicator is used to render the image.
But when we are using this <f:ajax> to render the image based on the indicator value, I am getting the error
malformedXML: During update repeatForm:repeat:2:redimage not found
How is this caused and how can I solve this?
This should work. I see only 2 possible causes:
Your bean is request scoped and does not preserve the <ui:repeat> value. Fix the bean constructor's job and/or put the bean in the view scope.
Your HTML output is syntactically invalid and is therefore confusing the JavaScript code who is responsible for updating the HTML DOM tree. You should not use <html> and <h:body> in the include file. It would be duplicated in the HTML output. You should only use it in the master page. The include page should look like this:
<ui:composition
xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets">
<h:panelGrid columns="4" border="0" width="90%">
...
</h:panelGrid>
</ui:composition>
Do not duplicate <html>, <h:head> and/or <h:body> in there.
