Problem using foreach inside tabpanel

[zizou84]

I am using Jsf 1.2 (with facelet 1.1),seam 2.2.0 and richfaces 3.3.0 in my project.

I need to create dynamic tabpanel usinj jstl librairy (1.2)

My code looks like this:

<rich:tabPanel id="tapPanel" width="700" rendered="#{myManagedBean.typeObservation!=null and myManagedBean.typeObservation.size()>0}">

         

        <c:forEach items="#{myManagedBean.typeObservation}" var="cap">

            <rich:tab label="Tab#{myManagedBean.codeObservation}">

     ...

      </rich:tab>

        </c:forEach>

    </rich:tabPanel>

The problem that even my managed bean is not empty and contains more than one item,i got tabpanel with only one tab.
