Currently i switched from version 11.12.14.12 to version 13.2.4.12 and i encounter a problem by using the NFormulaEngine.
The problem can simply be reproduced:
- Take the example code from your help site: http://helpdotnetvision.nevron.com/System_FormulaEngine_Formula_Engine.html
- Execute it.
- At engine.Variables.Add() an System.Exception with the message "Cannot compare a variant with null variant" will be thrown.
By simply switching back to the old version the problem is gone, but that's not the kind of workaround i like to do.

The problem occurs because the == operator was defined for the NVariant class, but we did not check for nulls. The problem is fixed and the fix will appear in the next service pack.
