Unable to establish the name of the entity class
Click HELP for text formatting instructions. Then edit this text and check the preview.Hi
I have a Object CourseOffering, which has a list of TaAssignments associated with it. It is a one to Many relationship between CourseOffering and TaAssignment.
Now the TaAssignment object has a field workTypeCode which is of type StuWorkTypes entity.
This issue is that, I am able to display the TaAssignment list related to a CourseOffering object. But when I click on any row of TaAssignment. I get the following error:
Unable to establish name of entity class edu.cmu.heinz.hcis.entity.StuWorkTypes_$$_javassist_19
I first add a new TaAssignment object for a selected CourseOffering. Then I go back to my initial screen and traverse to the list of TaASsignment objects associated with the selected CourseOffering.
Now the TaAssignment dataTable is clickable on each row. When I click on any row I get the above error.
Let me paste some code for reference.
First the entity class(StuWorkTypes)

The place where I get it is when I click on a row on the above dataTable. If you notice,it calls the method loadTaAssignment in the backing bean.
Let me know if you require the CourseOffering dataObject. Which has a one to many relationship association to TaAssignment.
I will paste the association only at this point.

Please let me know if anything is wrong with the entity StuWorkTypes. And the reason why it says, "Unable to establish the name of the entity class, edu....StuWorkTypes.
Any suggestions would be very helpful.
