PrimeFaces p:accordionPanel inside ui:repeat or c:forEach - jsf

Question

I'm trying to create multiple accordionPanels.
I tried to include this tag inside repeat elements (e.g. c:forEach).
The accordionPanel is well rendered, but I'm unable to switch from one tab to another.
These are some codes I tried:
<ui:repeat value="#{myBackingBean.myList}" var="o">
<p:accordionPanel dynamic="true" cache="true" multiple="true" widgetVar="accordion">
<p:tab title="Title 1">
#{o.data_one}
</p:tab>
<p:tab title="Title 2">
#{o.data_two}
</p:tab>
</p:accordionPanel>
</ui:repeat>
And also
<c:forEach items"${myBackingBean.myList}" var="o">
<p:accordionPanel dynamic="true" cache="true" multiple="true" widgetVar="accordion">
<p:tab title="Title 1">
#{o.data_one}
</p:tab>
<p:tab title="Title 2">
#{o.data_two}
</p:tab>
</p:accordionPanel>
</ui:repeat>
Both of these codes produces a list of accordionPanels, each with two tabs.
But I'm unable to switch from one tab to another: If I click one tab it does not open nor close (except for the last accordionPanel).
Noteworthy, if I put two or more accordionPanels by hand (without JSF loops) they works.
Also, I've checked the requests the browser sends when I try to open/close a tab. The requests I intercept are like:
<?xml version="1.0" encoding="utf-8"?><partial-response><changes><update id="mainForm:tabView"><![CDATA[
// something that always use the id of the HTML tag of the _last_ accordionPanel
</update></changes></partial-response>
How can I put an <accordionPanel> inside an <ui:repeat> or <c:forEach> so that I can still switch the accordionPanel's tab?

Its the problem with the widgetVar when you put p:accordion in ui:repeat, it will generate Accordion Panel components with different/dynamic Ids but not with different/dynamic widgetVar when you explicitly specify widgetVar like you're doing in your code.
Which is basically name to Javascript Object to access the Client side Api functions of p:accordion.
So If you are not using that widgetVar of p:accordions anywhere, Remove widgetVar attribute, then the widgetVar will be generated dynamically.
If you still want to use widgetVar, give dynamic name yourself, for example:
widgetVar="accordion_#{o.data_one}"
Note: I tried the above strategy with only on ui:repeat.
Using:Primefaces 3.5 and JSF 2.1.13 and its working for me.
