Leonardo Uribe commented on MYFACES-1881:
-----------------------------------------
Trying to solve with option 1 throws this error:
java.lang.UnsupportedOperationException
at javax.faces.component.UIViewRoot.setId(UIViewRoot.java:458)
at
org.apache.myfaces.application.TreeStructureManager.internalRestoreTreeStructure(TreeStructureManager.java:112)

I believe we do the proposed in option 2 and make easier the life:
2. call super.setId and super.getId properly on UIViewRoot.
Less problem, non OO clean but works.

> 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
> Priority: Blocker
>
> 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?
