Comment 2 Jan Stola 2009-10-20 15:09:10 UTC 
Reproducible. On the other hand, this use case doesn't have much sense => lowering priority.
Comment 3 Michel Graciano 2009-10-20 16:18:56 UTC 
IMHO, since it is normally for prototype, the UI should have an validation about how many rows and columns it could 
accept. If user wish to define an higher value he should define it by code which avoid OOME in IDE. Maybe we can address 
it by some NetFIX member.
Comment 4 Jiri Kovalsky 2009-10-21 21:18:08 UTC 
Honza Stola agreed to review and integrate possible patch coming from the NetFIX [1] team.

Comment 5 Michel Graciano 2010-01-25 16:04:31 UTC 
How many rows and columns should we accept?
Comment 6 Jiri Kovalsky 2010-01-26 04:47:32 UTC 
I would say not to be too much restrictive it could be like 50 columns and 100 rows? Or 100 x 100 maximum?

proposed patch

I have limited the number of rows and columns to 100.  If this is exceeded the the row/column spinner is reset to the previous safe value and an error message in red to that effect to output at the bottom of the dialog.
Comment 8 Jiri Kovalsky 2010-03-22 14:21:03 UTC 
Honzo, can you please review and integrate the patch? Thanks!
Comment 9 Jan Stola 2010-03-23 16:20:26 UTC 
I have applied the patch with several changes. There were few layout-related problems and it was possible to exceed the row/column limit using Insert button. These problems should be fixed now => marking the issue as fixed.
