Hi John,
PLP's can be a real bi%&h whe nyou're doing this kind of thing -
the reason for it is annoying but fairly simple - to actually load
any step of the plp, the *calling page* of the plp is reloaded
every single time. For example, if your object's edit handler
contains the cfa_plp tag call, it is being reloaded every
step/every iteration. This can be a real problem when using input
scopes, as if you start with a blank object, you'll often end up
with it overwriting the output scope with a blank object each time
you refresh.
There are some other reasons your problem can occurr, but I'd suggest
looking at that calling file first, and see if a little conditional
logic around the input object can fix it.
Give me a yell if you need any help (and if you get completely fed
up or you know fusebox, I'll give you a tag to completely replace
Plps <grin>)
cheers,
Toby
