And another AV, TTMSFMXGrid 2.2.2.9

FMX TMS FMX UI Pack
1

Hi, just found another ugly AV within TTMSFMXGrid.
Reproducable steps:

1. New Project + TTFMSFMXGrid
2. Insert TStyleBook with UseStyleManager := True and load any style. Connect with Form1.
3. set 1 cell with combobox or comboedit and set some strings within ComboItems
4. Event OnCellComboCloseUp: Fill another cell with Itemindex from ComboItems or whatever

Everything works until......you close Application and find EInvalidPointer + AV
Run Application with DebugMode.
It won?t happen if you have no Style activated !

Problem seems to be within FreeStyle.

Thanks for fixing!
Regards

Hi,

see following code. (Really easy to reproduce)

1. Use TStylebook and load style. Set UseStyleManager := True
2. Form1.Stylebook := Stylebook1
3. set in one Column: Editor := etCombobox or etComboEdit
4. Start app (F9/Debug Mode)
5. Close app
-> Runtime Error (if you just close app and have done nothing) or EInvalidPointer (if you edit cell with combo Editor and close app afterwards)

Regards.

Were you able to reproduce?

We have already answered your question by email. We are able to reproduce this issue, but when copying and pasting the TTMSFMXGrid in the same form, removing the original grid, the issue isn't reproducible anymore. It's still unclear why the invalid pointer occurs, we are still investigating this.

Sorry to bother you again:
Issue with Combobox still exists in TTMSFMXGrid 2.2.3.0!
Adapttostyle := true, Stylebook connected, UseStylemanager := true
AV happens after close/Destroy of Form with grid and you edited a cell with Combobox before
NO AV when Adapttostyle := false

Please fix,
Thanks &
Kind Regards
