JSF Pages goes away

I'm working with JSF and PrimeFaces and I am using Facelets as view technology. But I got an issue for which I can't find out the cause of the problem and the solution.

This is the Facelets template:

<div id="right">
    <div id="top">
        <ui:insert name="top"></ui:insert>
    </div>

    <div id="content">
        <div id="content-top">
            <ui:insert name="content-top"></ui:insert>
        </div>
        <div id="content-content">
            <ui:insert name="content-content"></ui:insert>
        </div>              开发者_如何学Go      
    </div>                
</div>

I'm using <p:layout> and <p:tabView> in content-content. When I try to add for example <h:form> to content-top, then I lose content-content from my index. How is this caused and how can I solve this?

Problem resolved by removing form id Hope that help's someone
