[jbpm-issues] [JBoss JIRA] Resolved: (JBPM-2791) jBPM variable mapping does not map correctly an empty String.

jBPM variable mapping does not map correctly an empty String. ------------------------------------------------------------- Key: JBPM-2791 URL: https://jira.jboss.org/browse/JBPM-2791 Project: jBPM Issue Type: Bug Security Level: Public(Everyone can see) Components: Runtime Engine Affects Versions: jBPM 3.2.7, jBPM 3.2.9 Environment: DATABASE: Oracle10g Reporter: Marek Baluch Assignee: Alejandro Guizar If I define the following variable mapping between ESB and jBPM (code bellow) and the mapped value (e.g. from ESB to jBPM) is an empty String then the result is null. <bpmToEsbVars> <mapping bpm="theBody" esb="BODY_CONTENT"/> </bpmToEsbVars> <esbToBpmVars> <mapping esb="BODY_CONTENT" bpm="theBody"/> </esbToBpmVars> The problem may lie in hibernate (http://opensource.atlassian.com/projects/hibernate/browse/HV-13). Also my test has shown that if I persist an object with some field set to an empty String then the object returned from the oracle10g database has the field value equal to null.
