Agreed, Designer already supports
transformations to do what you are asking for, but the data
editors should allow users to use this feature better. Will look
at it.
Thanks

Just a quick comment about mapping data,
I think that we need a specialized component to do that,
because is a cross cutting concern.
No matter if we are mapping task inputs and task outputs or a
form field, we need a graphical mapping component to take care
of that.
We need a graphical way to do something like
Input: Person -----> Person.name ---- <mapped to>
----> name
and the other way around
Output Person.name <----<mapped to>--- name

There are a number of ideas floating around on this -
and yes data mapping within a BPMN2 process is probably
now one of the hardest things to set up and maintain.
a) Have ability to map data outputs of a task to data
inputs of the connected tasks(s) with a single button
click
b) Ability to visualize the data flow of the process
c) Notifications of dependency errors when users decide
to remove a process var, globals, imports, etc
d) Ability to "copy" existing data elements such as
variables/globals/imports/etc from an already existing
process or a process template..this has been asked in
the community already and we are looking at it.
jBPM follows the BPMN2 specification for data setup and
mapping closely which is a good thing as it does not
introduce any wrappers around it (you might see other
tools use extensions elements for this heavily). I don't
think writing wrappers is a good idea, however making
working with data as simple and intuitive as possible
for users is very important so any
ideas/thoughts/contributions are very welcome :)
Jean-Jacques, If you want to jump on IRC and I'd be
happy to talk to you in detail about all of this as
well.
Thanks.

The problem is that BPMN2
specification requires the variables to be defined.
What you will need to do is to modify Designer to
automatically create the required variables according
to the IO specification of the tasks you have.
Unfortunately this is not as easy as it sounds ;).
Designer keeps a representation of the process in
JSON format. That JSON is then converted into BPMN2
when it is saved. When you open a process Designer
first converts it from BPMN2 to JSNO back again.
You will need to tweak the
Marshalling/Unmarshalling process..
The classes in charge of this are:
org/jbpm/designer/bpmn2/impl/Bpmn2JsonMarshaller.java
and
java/org/jbpm/designer/bpmn2/impl/Bpmn2JsonUnmarshaller.java
