[esb-issues] [JBoss JIRA] Updated: (JBESB-1966) EsbActionHandler cannot put property value of an object in jBPM scope to ESB message

[ https://jira.jboss.org/jira/browse/JBESB-1966?page=com.atlassian.jira.plu... ] Jacky Cheung updated JBESB-1966: -------------------------------- Description: I am developing application on JBossESB with jBPM as the workflow engine. In my process definition (jpdl), I have the following node: <node name="retrieve record"> <action name="fetch record" class="org.jboss.soa.esb.services.jbpm.actionhandlers.EsbActionHandler"> <esbCategoryName>Test</esbCategoryName> <esbServiceName>TestService</esbServiceName> <bpmToEsbVars> <mapping bpm="request.studentName" esb="studentName"/> </bpmToEsbVars> <esbToBpmVars> <mapping esb="status"/> </esbToBpmVars> </action> <transition name="ok" to="decide notify parent"/> </node> I got the following exception when jBPM transits into the node Caused by: org.mvel.PropertyAccessException: unable to resolve property: request at org.mvel.optimizers.impl.refl.ReflectiveAccessorOptimizer.getBeanProperty(ReflectiveAccessorOptimizer.java:374) After debuging, I discover JBpmObjectMapper has a bug that breaks the feature. Line 157 of the class (in JBossESB 4.3) is objectName = expression.substring(0, dotPosition-1); In my example, the content of expression variable will be "request.studentName" and the objectName will be "reques". This is wrong. The expectation is "request". The fix to this bug is simple. Just remove "-1" from the line so that the line should read as... objectName = expression.substring(0, dotPosition); I checked EsbNotifier and I found it call the same class. That means this bug will affect EsbNotifier as well. At the moment, I can change the bpm attribute to "processInstance.contextInstance.variables.request.studentName" to workaround the bug but my XML becomes difficult to read. I also breaks in JBossESB 4.4. The fix is very simple but critical (from my point of view). was: I am developing application on JBossESB with jBPM as the workflow engine.
