FRM-41014 - Cannot set attribute of null canvas item
abladbSep 2 2010 — edited Sep 2 2010Hi there,
I have a problem in my application. Everytime I place the cursor on whatever item of the same block the error occurs, so i think the problem is on the Block but I don't know how to handle it.
Actually, it happens when:
- On text items, when I place the cursor on it.
- On Lov buttons, after choosing/canceling the LOV.
- On calendar Buttons, after choosing/canceling the calendar.
- and so on the rests of diferent items of this block.
I have to say that this is not the only block on my canvas. Their block's items don't show this error.
So this is the information I guess you need to help me:
All the block's visible items has a Canvas attached.
All the non-visible has set the canvas property to NULL, and the visible property to NO.
The block is a DB block.
Any suggestion? Thank you all!!!
