User development, A new message was posted in the thread "Converting a variable back": http://community.jboss.org/message/529694#529694 Author : Jochen Mader Profile : http://community.jboss.org/people/jochen_mader Message: -------------------------------------------------------------- Solved it. looks like the documentation is lacking a little. To actually use the converter one needs to edit jbpm.execution.hbm.xml and add the converter to the converter typedef. Pretty hard to figure out and probably woth adding it to the docs.     <!-- ### TYPEDEFS ####################################################### -->   <typedef name="converter" class="org.jbpm.pvm.internal.hibernate.ConverterType">     <param name="org.jbpm.pvm.internal.type.converter.BooleanToStringConverter"    >bool-str</param>     <param name="org.jbpm.pvm.internal.type.converter.ByteToLongConverter"         >byte-long</param>     <param name="org.jbpm.pvm.internal.type.converter.CharacterToStringConverter"  >char-str</param>     <param name="org.jbpm.pvm.internal.type.converter.DateToLongConverter"         >date-long</param>     <param name="org.jbpm.pvm.internal.type.converter.DateToStringConverter"       >date-str</param>     <param name="org.jbpm.pvm.internal.type.converter.DoubleToStringConverter"     >double-str</param>     <param name="org.jbpm.pvm.internal.type.converter.FloatToDoubleConverter"      >float-double</param>     <param name="org.jbpm.pvm.internal.type.converter.FloatToStringConverter"      >float-str</param>     <param name="org.jbpm.pvm.internal.type.converter.IntegerToLongConverter"      >int-long</param>     <param name="org.jbpm.pvm.internal.type.converter.SerializableToBytesConverter">ser-bytes</param>     <param name="org.jbpm.pvm.internal.type.converter.ShortToLongConverter"        >short-long</param>     <param name="com.hre.portaldb.crosscommon.base.internal.DataEntityToLongConverter">dataEntity-long</param>   </typedef> -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/529694#529694
