NullPointerException with message: "Argument Error: Parameter message is null"
Hi,
What is the cause of such a message... am I missing configuration file?
I am seam newbie.
I am using jboss-4.2.3.GA, jboss-seam-2.1.1.CR1 and MySQL 5.0.67.
The program is a variation of the todo example with seam-gen generated forms and an expanded process-definition. Should rather ask on the jBPM list ?
I am posting here because this message seem to have been addressed in JBSEAM-3318 for the seambay example.
I didn't quite understand how what was fixed.
Below is stack trace and further down are the variables when the exception was thrown (collected with JBDS 2.0.0.Beta1).
Thank you for any help or clue.
