Description

Imagine a composite component for a text, where the attribute "asText" decide if a tc:in or a tc:out is used.

<cc:interface>
  <cc:attribute name="value"/>
  <cc:attribute name="asText" default="false"/>
</cc:interface>
<cc:implementation>
  <tc:in id="in" value="#{cc.attrs.value}" rendered="#{!cc.attrs.asText}"/>
  <tc:out id="out" value="#{cc.attrs.value}" rendered="#{cc.attrs.asText}"/>
</cc:implementation>

Without a layout manager the component show either the tc:in or the tc:out as expected.
Within a segment layout the component use two segments. One for the tc:in and the second for the tc:out.
If "asText=true" the first segment is empty and the second segment shows the tc:out.
If "asText=false" the first segment shows the tc:in and the second segment is empty.

This might be not the expected behavior, which I think is that the composite component uses only one segment.

As a workaround you can wrap the tc:in/tc:out with a panel:

<cc:implementation>
  <tc:panel id="wrapper">
    <tc:in id="in" value="#{cc.attrs.value}" rendered="#{!cc.attrs.asText}"/>
    <tc:out id="out" value="#{cc.attrs.value}" rendered="#{cc.attrs.asText}"/>
  </tc:panel>
</cc:implementation>

 

And the 'rendered' attribute on the composite component container doesn't work within a segment layout which should be definitely fixed.
