Kennard Consulting commented on MYFACES-3554:
---------------------------------------------
Your mention of the (MyFaces-specific) PostAddPreRemoveFromViewListener event
is very interesting. The Mojarra/MyFaces team had previously settled on the
following approach to dynamic component tree manipulation:

However there has recently been discussion that this may need to be clarified
in the spec, possibly with a new event (such as
PostAddPreRemoveFromViewListener). Would you care to weigh in on

> Hi guys,
> Thanks again for all the great work you do on MyFaces!
> There appears to have been an identical regression between MyFaces 2.0.11 and
> 2.0.12, and between MyFaces 2.1.5 and 2.1.6. My apologies for not picking
> this up earlier. This regression is likely related to a suite of unit tests I
> gave you in MYFACES-2935, though unfortunately I guess my suite didn't cover
> this particular bug?
> I attach 4 versions of the same sample application. You'll see it works for
> the 2.0.11/2.1.5 versions, but not the 2.0.12/2.1.6 versions. To reproduce:
> 1. Run the app
> 2. On the opening page click on contact 'Homer Simpson'
> 3. Click Edit
> In the regressed versions you will see:
> java.lang.IllegalStateException: component with duplicate id "form:j_id_b"
> found
