Leonardo Uribe commented on MYFACES-3554:
-----------------------------------------
I checked it again and the problem was not in UIStub, instead it was caused
because one facelet component was removed from the component tree, but note by
facelets algorithm, instead by some other logic in RenderResponse time. The fix
is just add that rule to the condition inside PostAddPreRemoveFromViewListener.
Manipulation of the components created by facelets algorithm should be avoided,
but still the trick is valid.

> 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
