Forums - CSHTML5

The problem is happening if a class inheriting from UserControl assignes the following member of another class inheriting from UserControl:

public static bool line12_useCustomDefinedMineral = false;

The following causes a javascript unhandled exception each time it is executed in the browser starting the second time it is executed but no error in the simulator:
Result.line12_useCustomDefinedMineral = (checkBoxUseCustomMineral != null && checkBoxUseCustomMineral.IsChecked.HasValue && checkBoxUseCustomMineral.IsChecked == true);

The following is a workaround, WHICH IS BASICALLY THE SAME CODE, does NOT cause an error in the browser anymore:
if (checkBoxUseCustomMineral != null && checkBoxUseCustomMineral.IsChecked.HasValue && checkBoxUseCustomMineral.IsChecked == true)
Result.line12_useCustomDefinedMineral = true;
else
Result.line12_useCustomDefinedMineral = false;

Exception in google chrome:

Hi

Please be sure to use CSHTML5 v2 instead of v1

Please let me know if it fixes the issue (it should).

Thanks
