> Key: MYFACES-3663
> URL: https://issues.apache.org/jira/browse/MYFACES-3663
> Project: MyFaces Core
> Issue Type: Bug
> Reporter: Leonardo Uribe
> Assignee: Leonardo Uribe
> Fix For: 2.0.17, 2.1.11

>
> In JSF 2.2 spec there is a change related to UIViewRoot.createUniqueId(). The
> javadoc says this:
> "... Generate an identifier for a component. The identifier will be prefixed
> with UNIQUE_ID_PREFIX, and will be unique within the non-NamingContainer
> child sub-trees of this UIViewRoot. ..."
> Thinking in MYFACES-3660, this fact becomes more evident. I think we should
> not wait to 2.2 and instead implement this is 2.1.x/2.0.x branches because it
> will improve the stability of the component tree under dynamic
> addition/removal.
> The suggested solution is do something like this:
> j_id__v_1
> j_id__v_2
> j_id__v_3
> j_id__v_4
> ....
> This solution will keep ids small and will not cause any conflict with
> facelet created components or components that receive the ids through
> UniqueIdVendor/NamingContainer hierarchy:
> j_id1
> j_id2
> j_id3
> j_id4
