wxGrid, wxMSW2.8.0rc1 and "invalid value for a cell with bool editor!"

[Volker Bartheld]

Hello!

I'm running the little wxGrid example prog below and get the "invalid
value for a cell with bool editor!"-assertion for a click on every odd
cell checkbox. cellval as used in %WXDIR%\src\generic\grid.cpp:1343 is
"0" and I don't see a reason why this should be considered invalid.

Strange that the code

         wxString cellval( grid->GetTable()->GetValue(row, col) );
 
         if ( cellval == ms_stringValues[false] )
             m_startValue = false;
         else if ( cellval == ms_stringValues[true] )
             m_startValue = true;
         else
         {
             // do not try to be smart here and convert it to true or false
             // because we'll still overwrite it with something different and
             // this risks to be very surprising for the user code, let them
             // know about it
             wxFAIL_MSG( _T("invalid value for a cell with bool editor!") );
         }
     }

refers to static wxString ms_stringValues[2]; element via a boolean
index but obviously the comparison fails. This used to work with
wxW2.7.0 if I remember correctly.

Am I missing something here?

Thanks for clarifying.

Volker
