Leonardo Uribe created MYFACES-3663:
---------------------------------------
Summary: UIViewRoot.createUniqueId() should generate unique ids
for all the component tree.
Key: MYFACES-3663
URL: https://issues.apache.org/jira/browse/MYFACES-3663
Project: MyFaces Core
Issue Type: Bug
Reporter: Leonardo Uribe
Assignee: Leonardo Uribe
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
