Decision Activity with Join finish don't work!
marc.carrio Apr 16, 2010 8:08 AMHi guys!
I use a jbpm4.3 with tomcat, mysql and jbpm-console 2.0 in Windows XP
I have the next simply process:
<?xml version="1.0" encoding="UTF-8"?> <process name="Alta" xmlns="http://jbpm.org/4.0/jpdl"> <start form="main/GestioUsuaris/Init.ftl" g="15,86,48,48" name="Nou Usuari"> <transition to="exclusive1"/> </start> <end g="615,108,48,48" name="Usuari d'alta"/> <task assignee="mary" form="main/GestioUsuaris/CA.ftl" g="454,82,100,80" name="Secretaria"> <transition to="Usuari d'alta"/> <notification template="task-assign"/> </task> <task assignee="mary" form="main/GestioUsuaris/Tel.ftl" g="212,36,100,80" name="Telefonia"> <transition to="Secretaria"/> <notification template="task-assign"/> </task> <decision expr="#{chkTel}" g="96,87,114,70" name="exclusive1"> <transition g="-16,-18" name="ok" to="Telefonia"/> <transition g="-23,7" name="ko" to="Nothing"/> </decision> <task assignee="mary" form="main/GestioUsuaris/Tel.ftl" g="211,178,100,80" name="Nothing"> <transition to="Secretaria"/> <notification template="task-assign"/> </task> </process>
The problem is after then 'Telefonia' task. the error that displays is:
org.jboss.resteasy.spi.UnhandledException: org.hibernate.NonUniqueResultException: query did not return a unique result: 2
org.jboss.resteasy.core.SynchronousDispatcher.handleApplicationException(SynchronousDispatcher.java:319)

I tested with a "join" after tasks and before ('Secretaria' and 'Nothing') task but the error is the same.
The examples don't have joins! How I can do a decission activity with "joined" finish?
Thanks a lot for advance!
