Crash during creation of grid

[Pellaeon]

Hi,

I am new to TeeGrid. I use Rad Studio 12 Community Edition Delphi.

I have the following situation. I have an existing program and have dragged a TeeGrid into the GUI. I simply dragged it into the GUI, created two columns and did nothing else.
When I start my program now, I get an access violation. It happens in Tee.Grid.RowGroup.pas in the method TRowGroup.ChangedBands. FRows is nil and therefore an access results in a crash (see attached image).

How can I solve this? As I wrote: I only added the control to my GUI and startet the program, nothing more.
I have created a simple test program in advance. There it works fine. I have no clue what the problem could be.

Best regards
Pellaeon

PS: and another hint: it would be cool to have an installer of the TeeGrid for the licensed version for Community Edition users. I followed the instructions in this post: https://www.steema.com/support/viewtopi ... ity#p79148. But that's awkward. So a better solution would be nice. Atm I can't use 1.18 because there is no binary version for download.
