I have two entity EJB's with a one to many set mapping relationship (all CMP), this seems to work nicely with 1.4.0, upgrading to 1.4.4 breaks things though when try to get the set from the parent EJB (the set returned is null). The getter method is getCategories().Oddly enough if I print the categories field value within the EJB method, it shows up correctly, but getCategories() called from another session bean returns null. Has anyone else had any issues similar to this in 1.4.4? Hani
