[jbpm-issues] [JBoss JIRA] Commented: (JBPM-895) null pointer when create new sub process definition

[Victor Ruiz (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBPM-895?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12506583#action_12506583 ] 

Victor Ruiz commented on JBPM-895:
----------------------------------

It affects version jBPM 3.2.6 too since I've seen it.
I've used binding='late' attribute in my live environment (since sub-process loading is done by means of jPDL).
I've used Michael Thiele solution in my test environment (since sub-process loading is done programatically).
