Header file issue in datatypes.h

I am current working on upgrading engine from 16.1 to 17.0. After I upgrading all the header files, I found my module cannot compile due to the line of code in datatypes.h as follows:

Variant& operator =(const Property& other) { operator = ((Variant)other); return *this; }

The error message is as follows:

error C2440: 'type cast': cannot convert from 'const FlexSim::Property' to 'FlexSim::Variant'

I can make it compile either by commenting out this line or change this line to be

Variant& operator =(const Property& other) { operator = ((const Variant&)other); return *this; }

Is this a bug? Or there are reasons for this? How to make it compile without changing any header code?

Thanks, Hao

Sorry about the issue. This file compiles correctly in VS 2013 but not VS 2015.

You can fix it by changing line 1392 of datatypes.h:

From:

Variant& operator =(const Property& other) { operator =
((Variant)other); return *this; }

To:

Variant& operator =(const Property& other) { operator = (other.operator
Variant()); return *this; }

We will get this fixed on our end in the next version, but you can change it yourself manually to fix it now.
