R: R: R: how can i do to get activity's transitions?

Thanks a lot for your reply, using the extended attributes is the nearest solution to my needs.

Oggetto: Re: R: R: [shark] how can i do to get activity's transitions?

For most conditions, a Boolean or a 3 values enumeration is enough
(the classical 'accepted?' or 'document status' variable).
Also don't forget if you allow success to take values -1, 0 and 1
(considering you have 2 conditions + a fallback transition),
you need some way to tell the user what those values mean.

A more elegant solution if you realy need such behaviour is to add extra
informations to the action using extended attributes

eg, add the following extended attributes to your action:
RESULT_VALUE_success="1, Operation is successful"
RESULT_VALUE_success=0", Operation is unsuccessful"

You can then use the adminmisc interface to query extended attributes of
current action and show options to user
(please note, this is currently how the shark swing client determines
you have to update/read some variables)
