t:tree2 + MyFaces Core: FacesException: facet 'x' already has a child associated
I'm experiencing problems using t:tree2 with MyFaces Core that I don't
get with the JSF RI.
When I run the application with MyFaces Core I get this error
(detailed stack trace below):
javax.faces.FacesException: facet 'reportGroup' already has a child associated.
What could be causing this issue?
Here're the configuration details:
- Tomahawk 1.1.5 snapshot
- MyFaces Core 1.1.5 (doesn't work) / JSF RI 1.1_02 (works)
- Oracle ADF Faces
- JDeveloper 10.1.3.2.0 + Oracle OC4J 10.1.3.1.1 (embedded)
Here's the stack trace:
javax.faces.FacesException: facet 'reportGroup' already has a child
associated. current associated component id:

Re: t:tree2 + MyFaces Core: FacesException: facet 'x' already has a child associated
Posted by Mike Kienenberger <mk...@gmail.com>.
Well, you didn't post any page code, but the short answer is MyFaces
has better error reporting :-)
A facet can only have one child. Apparently you've specified multiple
children for reportGroup.
If you need mutiple children, enclose them in an h:panelGroup.
