Hi,
Here's a note from http://wiki.apache.org/cocoon/RhinoWithContinuations that
explains what's going on:
NOTE: Captured continuation does not save the state of the variables, but
rather pointers to the variables. Example: two continuations will share one
instance of the local variable declared in the function, if those two
continuations were created during execution of the same call of this
function. -- Vadim
The result of this is that when you set the form variable to the search
results form, you change the form variable in the earlier continuation too
so when you click the Back button and submit, an instance of "form B" does
the processing instead of "form A".
Probably the easiest thing to do here is to use two different variables for
the two forms. If this is awkward (e.g. you're generating forms in a loop),
you can also use a page local variable to get the behavior you want.
