[jboss-user] [jBPM] - Re: Exception retrieving task

jnorris [https://community.jboss.org/people/jnorris] created the discussion "Re: Exception retrieving task" To view the discussion, visit: https://community.jboss.org/message/744275#744275 -------------------------------------------------------------- Hi All, I'm pretty sure the issues with getting a task are due to the I18NText null values.  When a process is started a task is created.  There are also 2 rows created in the I18NText table.  The first row has a value for TASK_DESCRIPTIONS_ID and nulls for TASK_SUBJECTS_ID and TASK_NAMES_ID.  The second row has a value for TASK_SUBJECTS_ID and nulls for TASK_DESCRIPTIONS_ID and TASK_NAMES_ID.  I would think only one row would be created for a task.  Does anyone have a clue what's  going on? This is a critical issue for me and I have missed a deadline already because of it. I'd appreciate any help in resolving this matter. BTW, getting a list of tasks for a user works fine.  Any other methods such as getTask, claimTask, etc. all cause a null pointer exception to be thrown similar to the one included below: Jim
