I was thinking about adding a custom node which contains an action which actually is a container for other actions. This container action has a fixed set of pluggable actions. For example suppose I want a node where I need to perform A, B and C in sequence. I could model it using three consecutive nodes or I could add a node with configuration:
| <node>
| <A class="com.xxxxxxx.ImplementationA">
| <B class="com.xxxxxxx.ImplementationB">
| <C class="com.xxxxxxx.implementationC">
| </node>
|
Of course I could also create a single action with:
| <node>
| <containerAction class="com.xxxxx.containerAction">
| <A class="com.xxxxxxx.ImplementationA">
| <B class="com.xxxxxxx.ImplementationB">
| <C class="com.xxxxxxx.implementationC">
| </containerAction>
| </node>
|
But then I need to parse the configuration of A, B and C actions myself. I woud end up with a containerAction containing a configuration property with xml containing other action configuration.
So I felt the need to have action configuration which is recursive and some kind of container actions.
Since I don't see a way to do this right now in Jbpm (only one action allowed) because I prefer not to parse configuration in the execution of the handler and don't want to add a separate node for each action child, I came up with the multiple action node idea.
Anyway, I'm still searching the best solution, also considering the limited time constraint (you know how it feels ;-)).
thx,
Olivier.
