Jay swaminathan commented on JBPM-1024:
---------------------------------------

Sorry, this is the error I get:

Error getting variable map: An exception of type "org.jbpm.JbpmException" was thrown.  The message is: couldn't deserialize object

Unfortunately, the exception is swallowed somewhere in the execution path.  Based on source code, its clear that it is unable to

readObject() for some reason.  However like I mentioned before, my class implements java.io.Serializable and all it has are three string instance variables.

> Storing an serializable object in a process should write an "R" in the column "converter" in table JBPM_VARIABLEINSTANCE.
> But the value of the field is "null".
> The cause:
> The converter ID is retrieved in class org.jbpm.db.hibernate.Converter at line 63.
> For the case of the SerializableToByteArrayConverter the ID is "null".
