<div class="jive-rendered-content"><p>Thanks Tihomir.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Unfortunately that doesn't work, I get a NullPointerException at org.jbpm.bpmn2.xml.TaskHandler.readDataInputAssociation(TaskHandler.java:120).</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>My reading of the code suggests <transformation> is not implemented in jBPM 5.2.0_Final.  To me, it seems readDataInputAssociation() only handles <assignment>.  And indeed, <transformation> is not listed as supported in chapter '6.3 Supported elements' of the documentation.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>The code looks like it's setup to always treat the <to> and <from> as an XPath expression, so I guess I'll have to go through the code to find out what it can do and how to do it.  Unless someone can point me to some documentation..?</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Thank you for your suggested alternatives, but to be honest, I don't really like them.  My goal is to make the process to be as 'business process' as possible, so a task to prepare the parameters for the next task is not in-line with that goal.  I'm only using domain-specific tasks, but I don't think it's their job to prepare their own input and output parameters from whatever format the caller uses.  I think there should be a way to map tasks' inputs and outputs in the process itself, and that's what I'm trying to do with these dataInputAssociation/dataOutputAssociations.  </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I will update this discussion thread with any progress I may make.  In the meantime, any other suggestions would be most welcome.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Thanks again.</p></div>
