Error in python exported code when adding PropertyGrid OnChange event

[rjdza]

I am using Python 2.7.12 on Windows 10.

When adding an OnPropertyGridChanged event (PropGridChanged) I get the error "global name 'NULL' is not defined" when including the python export file in my project.

The offending line seems to be the NULL in the generated code:
self.pgSettings.Bind( pg.EVT_PG_CHANGED, self.PropGridChanged, NULL, this)

Everything seems to work as expected when I remove the NULL, this portion and just use:
self.pgSettings.Bind( pg.EVT_PG_CHANGED, self.PropGridChanged)

In the above, pgSettings is a wxPropertyGrid.

The PropertyGridManager event creates the code without the NULL, this portion.

I've not included any additional code as this seems to be a fairly simple problem and resolution. Please let me know if anything more is required.

I should have mentioned that I experienced this error in v3.5 RC1 and v3.5.1 RC1.
