Werner Punz commented on MYFACES-2884:
--------------------------------------
Ok I tried it with MyFaces 2.0.1, and could not reproduce it without ext-val,
the funny stuff however is that if the form has an id form I get following
error:
java.lang.IllegalStateException: component with duplicate id "form" found
Caused by:
java.lang.IllegalStateException - component with duplicate id "form" found
By changing the forms identifier to something else I am able to run it without
errors.
The problem is not there on the latest 2.0.2-SNAPSHOT trunk.
