UIViewRoot setId called on UIComponentClassicTagBase throws
UnsupportedOperationException
-----------------------------------------------------------------------------------------
Key: MYFACES-1881
URL: https://issues.apache.org/jira/browse/MYFACES-1881
Project: MyFaces Core
Issue Type: Bug
Affects Versions: 1.2.4-SNAPSHOT
Reporter: Leonardo Uribe
The latest myfaces core 1.2.4-SNAPSHOT throws this exception, because setId was
disabled.
This is because javax.faces.webapp.UIComponentClassicTagBase try to set its id:
We have two options here:
1. do not set its id on UIComponentClassicTagBase
2. call super.setId and super.getId properly on UIViewRoot.
I don't know if there is side effects (a component without id? what happens
when its state is saved and restored?).
Suggestions?
This is the exception
