Guy, I haven't used 1.1 in a while, but I think I hit a similar problem
with component binding in 1.2. If I tried to add the some UIComponent
instance to two different parents, the second parenting would always
undo the first. What you're doing is fairly similar, though you create
each component anew with each invocation of getForm(), so it may not be
quite the same. Have you tried duplicating getForm(), say, getForm2(),
and binding each form to a different method just to see what happens?
