ui:repeat is rendered in a later phase than c:forEach. Here's an explanation.

c:forEach is the way to go here, since this is invoked in view build time.

ui:repeat is invoked during view render time, so p:panel would have no knowledge of the data being created by ui:repeat.

What do you mean by `dynamic content`, could you show us an example? Your provided example would work perfectly fine with `c:forEach`. – Menno Apr 29 '13 at 13:10
Ok ,I'm using selectoneMenu to show show details of the selectect item – FERESSS Apr 29 '13 at 13:15

when the user select an item the content of panel is showing according to the selected one ..I have a problem with foreach so I work with repeat – FERESSS Apr 29 '13 at 13:17
Could you specify the problem you are experiencing? – Menno Apr 29 '13 at 13:26

You could switch to using <h:dataTable> to iterate over the components:

<h:dataTable var="var1" value="#{composantbean.categorie.proprietes.toArray()}">
    <h:column>
        <h:outputText value="#{var1.nomProp }(#{var1.unite}  )"  />
    </h:column>
    <h:column>
        <h:inputText value="" />  
    </h:column>
</h:dataTable>

Enclose it within a <p:panel> to make it work. Otherwise, make use of <c:forEach> as it's a good fit for your use case.
