JSF 2 Composite Component rendering problem

My composite component (cc) creates an inputText-Field. The important part is, that it is rendered depending on the models property "visible". The model is given to the component via parm "name".

<cc:interface>
  <cc:attribute name="name" required="true"/>
</cc:interface>
<cc:implementation componentType="ch.sbi.pt.components.PMSInputText">
      <h:inputText value="#{cc.attrs.name.value}" rendered="#{cc.attrs.name.visible}"/>
</cc:implementation>

In the view i have a panelGrid with 2 cells/row: the first row has a label and my cc, the second is not important. The label renders itself with the same model-property as my cc does.

<h:panelGrid columns="2">  
   <h:outputText value="Name" rendered="#{person.name.visible}"/>
   <sbic:pmsInputText name="#{person.name}"/> 
   <h:outputText value="Next Label"/>
   <sbic:pmsInputText name="#{something.name}"/>
</h:panelGrid>

The result (and problem) is the following, if "visible"-property returns "false": None of the components are rendered (perfect!) BUT the cc resulting HTML leaves an empty cell (e.g. <td></td>) which results in a ugly layouted HTML-Table (offset one cell):

<table>
<tbody>
<tr>
<td></td>
<td>Next Label</td>
</tr>
....

As far as I understand this has to do with the lifecycle (jstl vs. jsf): my cc renders before the <h:outputText../> but how can i get rid of the empty cell (e.g. <td></td>)? Am i missing something here?

Thanx for your help, experts! Marc

This is fully expected. The composite component is rendered. Only its children are not. You need to move the rendered attribute to the composite component instead.

<sbic:pmsInputText name="#{person.name}" rendered="#{person.name.visible}" />
