I would like to modify an instance of a workflow (not the workflow definition) on the fly by adding/removing task nodes in JBPM.
Ex if there is a workflow definition with nodes A-> B-> C-> D and there are 10 instances running, is it possible to change one of these instances a-> b-> c-> d by adding a new task node like a-> b-> b1-> c-> c1-> d.
Let me know if this is at all possible in JBPM.

According to [JBPM-769] the way to use ones own identity implementation for task assignment is to specify a handler class.
The example given is...
| <task name="create jira task">
| <assignment handler="com.owens.OwensAssignment">
| <expression>this.expressiontext-->is[injected].in.the.expression.field=>of-the<--assignment[handler].class</expression>
| </assignment>
| </task>
|
However it appears that it is not possible to specify the expression via the Process Designer, it can only be entered directly into the XML.
So, is there something I'm missing, or should a feature request be created to permit the inclusion of an expression when using a custom handler?
Thanks in advance
Steve
