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.
