[jboss-user] [JBoss jBPM] - Re: variable scope from a script

Create variable works indeed. It also works to update an already existing variable. So my problem is solved, thank you! However, IMHO, I find the behavior strange: - Even though a token is explicitely provided, setVariable elects to ignore it. Rather throw an exception stating the variable does not exist, but do not ignore that parameter; there is a two-parameter method for a more "agile" behavior. - createVariable can be used to create and update a variable. However "create" is much more specific about what is going to happen than "set", and I had not expected it to update also. Personally I find the following behavior more logical: - createVariable: create only but not update, exception if variable exists - updateVariable: update only, exception if not exist - setVariable: create if not exist, otherwise update Thanks!
