No, the getList() (called in the LDM load()) is only called once. For the buttons add, edit and delete, the processng is like this:
- ldm.load() (which calls getList()) - button.onSubmit() - ldm.detach() (called two times) For the save button, the processing is: - button.onSubmit() - ldm.load() - ldm.detach() (called two times) I've discovered another anomaly in my code. When I choose a record and click the edit button, the record is displayed in the edit group. If I then choose cancel, the edit group is no longer displayed and the ddc selection is null. I then choose another record from the list and edit and the previous record information is displayed in the edit group even though the ddc shows the newly selected record. I added get/set for the selectedRecord and set breakpoints, but those methods are never called. Since the edit group components use PropertyModels, shouldn't the get method be called each time the page is submitted?
