Hello,
As I can see in your code, you are assigning the 'OptionList1Click' method twice to different objects.
First on TOptionItem on line 49:
::oItems_PriGru:OnClick := "OptionList1Click"
And also on the TOptionList OnClick event.
For that reason you are receiving two events when ever a click is performed, the first one with oSender as TOptionItem object, and the second one as a TptionList. Since the property nImage is only available on TOptionItems, a RTE arised when oSender was a TOptionList.
The easiest way to solve this problem is simply deleting the TOptionList:OnClick event. That's all.
BTW, this may function on previous versions of Xailer because the Windows API does not provide a Click message for any control but we decided to include it on Xailer control some time ago.
I include with this message your project corrected.
Regards,
