I tracked down the problem to a table column having all null values, it is not the index of a list, but the key of a map:
<map name="definitions" cascade="all"> <key column="PROCESSDEFINITION_" /> <map-key column="NAME_" type="string"/> <one-to-many class="org.jbpm.module.def.ModuleDefinition" /> </map> it is the NAME_ column that contains all null values, when I populate the column with proper values for each row it works fine the problem must in this case be related to an improper process definition (the contents of the tables are deserialized from XML), I'll let you know if this is actually the case -- Wouter Zoons - [EMAIL PROTECTED] http://www.andromda.org/ _________________________________________________________ Reply to the post : http://galaxy.andromda.org/forum/viewtopic.php?p=2566#2566 Posting to http://forum.andromda.org/ is preferred over posting to the mailing list! ------------------------------------------------------- This SF.Net email is sponsored by the 'Do More With Dual!' webinar happening July 14 at 8am PDT/11am EDT.
