the proper way to do that as a patch, etc?

I disabled the constraint to see if it was actually going to write the correct

It's one of those errors that chains up to the Hibernate save so there's no

I do this the way you suggest in bold. I implement it using custom Actions
which use Java code to create new process instances.

Can you post the specific code that is having problems? Here is a sample of
script code I use, where contractSummary is a variable placed into the workflow
context in Java code:

I think you can do all that. I dont see "$myVar" in your code sample, and your
second sentence didn't quite finish. Look at decision nodes, and look at the
script elements and variable tags in jpdl. Take a look in the docs and post
here if you need clarification.

I am handling this in my workflow application similar to the second way you are
considering, by adding a "cancel" node and linking that with transitions. I
only link it to the major nodes though, and assume that it can make it to a
major node before being cancelled.

I love the graphical design editor in Eclipse, but I often find that by editing
the actions/script in the XML not carefully enough, or sometimes even just
saving, closing, and opening it again, I get an error and cannot open the file
in the designer. I then go through a slow and arduous process
That seems like the perfect solution, and I just wasn't aware of that XML
parsing functionality. I'll test it out. Thanks Alex!

Has anyone defined swimlanes externally to the process definition? (Does that
even make sense?) I have many workflows that involve the same swimlanes, and
right now I am cutting and pasting the XML into each process, which is not the

I am trying to figure out the best way to do this as well. Please share any

I dont have a jBPM answer for you, but if you create the new schema in a

of Toad Xpert Edition) to generate a schema diff SQL script. If you do so,

You would not need to send any input to a node, but rather you would need to
send the input to a specific process instance which is waiting for that input
