<div>Sounds good, so I guess a generic tool
that can help resolve the fact models across rules/processes.<br>
The UI can then utilize this tool when needed.<br>
<br>
When you gonna work on that? :)<br>

Thanks.<div><div class="h5"><br>

<div>This is not about using expressions to resolve values at
runtime, you can consider a data mapper a tool to create those
expressions based on the data available. This kind of tools can
be also used for Rules as well, so the process designer is just
one component that can use that. </div>

</div>
<div>The idea is </div>
<div>1) recognize that we have a Person (Person object and person

<div>2) look for its fields (age, name, address)</div>
<div>3) look for the already defined variables in the scope where

Can't think right now why it would be useful to have

<div>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. <br>
<br>
a) Have ability to map data
outputs of a task to data
inputs of the connected
tasks(s) with a single
button click<br>
b) Ability to visualize the
data flow of the process<br>
c) Notifications of
dependency errors when users
decide to remove a process
var, globals, imports, etc<br>
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.<br>
<br>
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 :)<br>
<br>
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.<br>
<br>
Thanks.<br>

I want to

<br>
I want to
remove the
need of
declaring

the mapping

<br>
When you have
lots of
workflow, it's
start to be
very annoying.<br>
<br>
I'm thinking
of moving this
declaration of
mapping to do
it at runtime.<br>
<br>
Like having a
spring
configuration
file to
declare all
variables
needed for a
series of
workflow.<br>
<br>
And next do
the mapping of
variable by
IOC with work
item or
something like
that.<br>
<br>
I want to keep
the scope
variable
between
process and
work item.<br>
<br>
I want to make
easier the
work of people
doing the

the tool for

Any idea ?<br>
