Which inserts all the component\'s chi

Answer 1

I've encountered the same problem and managed to find children of a composite component within it's facet 'javax.faces.component.COMPOSITE_FACET_NAME'.

In Java it's like this:

// we are within some method of UIComponent
UIComponent childrenHolderFacet = getFacets().get("javax.faces.component.COMPOSITE_FACET_NAME");
Iterator childrenIt = childrenHolderFacet.getChildren().iterator();
...

In JSF it's something like:

#{component.getFacets().get("javax.faces.component.COMPOSITE_FACET_NAME").children}

Hope it helps.
