[jira] [Created] (MYFACES-3410) Method parameters only work on
'top-level' managed beans
Method parameters only work on 'top-level' managed beans
--------------------------------------------------------
Key: MYFACES-3410
URL: https://issues.apache.org/jira/browse/MYFACES-3410
Project: MyFaces Core
Issue Type: Bug
Environment: MyFaces 2.1.4, Tomcat 7.0.21 (also tried JBoss AS 7)
Reporter: Kennard Consulting
When using JSF 2's 'method parameters' feature:
#{fooBean.add(42)}
The evaluation fails when trying on a child object:
#{fooBean.foo.add(42)}
As a workaround you can use:
<ui:param name="_foo" value="#{fooBean.foo}"/>
#{_foo.add(42)}
But this seems like it should work without needing ui:param?
See attached test case.

Werner,
It's a good point. It occurred to me too. But I tried it in Tomcat 7 and got the same result. The attached test case is for Tomcat 7.
Regards,
Richard.

---------------------------------------------
This appears to have been fixed somewhere along the line. It is broken in Tomcat 7.0.21, but fixed in Tomcat 7.0.25.
Would it be worth figuring out how this happened? It's not JSF (I used MyFaces 2.1.4 both times) or el-api.jar (both Tomcats use 2.2.FR), so I guess it must be in the EL implementation somewhere?
Could you help get some regression tests around this?

--------------------------------------
Just a comment from a bystander, this also could be a bug in the underlying jboss el implementation.
