I don't know if this is a environment problem or a general one. Anyway it is mad and took me a long while to find out what it is.
Here we go:
- I have a tabular form with standard APEX processing.
- The tabular form includes a single check-box column with y,n
- The check-box column is conditional
Now whenever I try to save my changes. Nothing happens. The "Mulit Row Update"-Process does not get executed.
After some analyzing I found out that there were no more hidden elements for the tabular form created. APEX just didn't know what to save.
If I take the conditional display away it works fine.
We use Application Express 4.1.0.00.32
Is this a known bug? Have you ever experienced something like that?
After some more investigation and a good hint from a colleague I found the real reason.
What I didn't mentioned: All columns where conditional and in that case APEX doesn't know where to add the hidden elements. I made another column unconditional and it worked (even with my conditional single check box).
Good to know! :)
