I’m trying to use IWDBJQGrid without success with Delphi XE5 and IW 15.2.21.
Whenever the grid is connected to an open dataset via a datasource the application fails with an AV. The error message is “Invalid pointer operation”.
The same error happens if I run the demo project.
If I change IWJQDBGRID with IWDBGrid everithing is fine.
I’m starting to think that it may be an installation/configuration problem of my machine. However this problem happens just if I use IWJQDBGrid.
Can anyone who may have experienced something similar give me some clue to where to look?
Thanks in advance
Fabrizio
I can't recreate this. The demo project works correctly in all tested scenarios.
Did you modify the demo In any way? If so, can you please attach the modified project here?
Regarding your installation: Please check the library path. See if it contains a path to any older IW version installed on your machine. If so, remove it and rebuild the app.
