Hello,
I'm getting confused with something I think may be my mishandling of conversations. I have a DepartmentList.xhtml screen that has a commandButton that takes me to a DepartmentEdit.xhtml to create new Department entities. After creation I'm returned immediately to DepartmentList (no intermediate review page like the default seam-gen).
The first time I create a Department it works great. If I immediately try create another Department I get exceptions on DepartmentEdit.xhtml. Sample exception dump below, but essentially it can't find properties of DepartmentHome. (I can cut the field its complaining about out of my screen and it will toss its lunch over another DepartmentHome field.)
I show the code in DepartmentList.xhtml that links to DepartmentEdit.xhtml. I also show the save button code in DepartmentEdit.xhtml and included DepartmentEdit.page.xml.
Thanks in advance for any clues.
