This seems to be behaving correctly.  <fb:case/> only performs its child 
bindings if its id matches the value of the union's case widget.  Since 
you just set the case widget's value to "FALSE" via the first fb:value 
binding, the <fb:case id="TRUE"> will not be executed.

If you want that group of bindings to always be executed you should be 
able to just remove the fb:case wrapper.
