You must explicitly define the id's. Id's can be defined on the component or
element.
<component jsfid="lastName" extends="requiredInputText" id="lastName" ≶
<attributes≶
<set name="value" value="#{myBean.lastName}" /≶
</attributes≶
</component≶
*And/OR*
<component jsfid="requiredInputPanel" extends="panelGroup"≶
<element renderId="1" jsfid="requiredInputText" id="lastName" /≶
<element renderId="2" jsfid="message"≶
<attributes≶
<set name="for" value="lastName"/≶
<set name="styleClass" value="errors"/≶
</attributes≶
</element≶
</component≶
>Second question, can I define a component that extends requiredInputPanel

The inheritance only has the capability of overriding attributes of the parent
and contained elements. Overriding an element will replace the element. The
"signature" for inheritance is the renderId of the element.
There is not a way to override an attribute "horizontally" meaning you cannot
specify a jsfid that represents containment similar to the generated clientId
of the JSF component.
"myPanel/lastName/validator/validator1"
I might be interesting think about being able to apply customizations to a
subtree "horizontally". This would allow you to slip in an override without
restructuring the hierarchy of the inheritance. Challenge would be
creating/requiring a unique id to represent containment. IdÂ’s generated by the
component could not be correlated to the metadata component id's.
In short, the only way to override a validator of an element of an extended
component would be to replace the element.
<component jsfid="requiredInputPanel" extends="panelGroup"≶
<element jsfid="inputText" renderId="1" id="lastName" ≶
<validator jsfid="commonsValidator"≶
<attributes≶
<set name="client" value="false" /≶
<set name="server" value="true" /≶
<set name="type" value="required" /≶
</attributes≶
</validator≶
</element≶
<element renderId="2" jsfid="message"≶
<attributes≶
<set name="for" value="lastName"/≶
<set name="styleClass" value="errors"/≶
</attributes≶
</element≶
</component≶
>Also, any suggestions on accomplishing this are welcome.
