Dear All,
I'm currently facing a problem with an addon solution.
- Built a custom BO with 3 [0,n] subnodes nested into each other, here's the data model:
- When creating an instance via the QA User Interface (and thereby new (sub)node items), these implicit parent-child relations work wonderfully out-of-the-box: When you select a row, the respective entries in the table bound to the subordinate node will be displayed therein.
- BUT: When you save, close and reopen the same instance, no content of the subnodes beneath level 1 will be displayed anymore:
- Double checked with a query to make sure these subnode items actually exist in the database, they do:
Some strange facts about this:
- I have another (very simple) UI here which was created by a student of mine, also with 3 subnodes where this works fine, also when opening a saved BO instance
- Spent AGES fiddling around with UI Designer properties and SADL queries by parent node ID crashing for no reason (by the way: it is sooooo awful not to be able to debug this unholy silverlight blackbox!), no improvement.
- Then I re-bound all lists and data fields (to backend nodes and elements) and it worked! For 10 minutes. Then, when testing the UI, although I hadn't changed anything in the meanwhile, I ran into a silverlight exception(which provided no valuable information at all, as usual). Afterwards it stopped working and never worked again !?
Now my questions:
- Has anyone had any similar problems and found a solution?
- Is there something particular to consider here?
Appreciate all hints and comments!
Kind Regards
Pablo
