[ClickEvent : Cannot read Propery 'value' of null]

Hi, I'm getting the following error (in browser console) "Cannot read Propery 'value' of null".

what happens is this, i try from a uniLabel, i put a simple "Showmessage('1'); " just for testing purposes.

by the attached video to understand the problem. it happens that it works randomly sometimes and simply stops working the event and starts displaying the message in the browser console (but in debug nothing appears in delphi). I checked if it could have an influence from somewhere else, but we isolated the form and the bug persisted. any idea how to solve? in this case we need the click to display the information in a panel on the side, that's all, call a simple function.

Sorry, do not enter the component correctly.

What I am using is the TUniMDbGrid component that is part of the mobile packages but it does not have the DrawColumnCell function.

Begin

   Excel: = CreateOleObject ('Excel.Application');

   Excel.Visible: = false;

   Excel.WorkBooks.Open (FileSource.Text);

   ExcelSheet: = excel.Workbooks [1] .WorkSheets [1];

   DData: = Excel.WorkBooks [1] .Sheets [1] .Cells [1,1];

End;

 

When I use this function in uniGui it's message:

[Export information to excel]

Thanks for the help, was using the visual component, when I used only via command, it worked perfectly.

[Export information to excel]

Possibly not, because if you remove the SMExportToXLS component from the form it normally opens

[Export information to excel]

I installed the SMSExport package and put the components SMEDatasetDataEngine1 and SMExportToXLS but when I enter the screen that includes these components it gives the message:
Raised exception class EConvertError with message 'Can not assign a nil to TFont'

Please any tips?

Thank you
