[JBoss jBPM] - Re: Using Drools for jBPM decision
by turpin_vincent
hi,
First thanks for answering me so fast. Actually i understood that the problem comes from the data handler witch return "null" in spite of "toDeliver" or "toEnd". But i can't find why, the file AccountAproval.drl is correctly parsed and even if when the rule doesn't evaluate to setOutcome("toDeliver"), it return null, i think that the condition in the rule is evaluated (if the syntaxe condition isn't correct i get an error about that).
For the moment i just can add that i'm working from this example: http://docs.jboss.com/seam/latest/reference/en-US/html/drools.html (chapter 14.3) btw that's why i execute the same rules again on the transition 'toDeliver' (to be closest from the example) and there is no difference if i delete this part:
| <action class="org.jboss.seam.drools.DroolsActionHandler">
| <workingMemoryName>accountApprovalWorkingMemory</workingMemoryName>
| <assertObjects>
| <element>#{actor}</element>
| <element>#{orderStock}</element>
| </assertObjects>
| </action >
I'm going to try an other way with less code in the process and more in the java class like in this example: http://www.jboss.org/community/docs/DOC-11096.
I give my java class too (mabe it will help) i think that the problem can come from the fact that i dont know if i have to declare again the data handler in this class or if the code in the process is enough.
