AF Data Reference Programming : Null value for timeContext in GetValue.

I am currently working on a Data Reference that has to use the timecontext.


I have overloaded the AFDataReference class and in particular the GetValue and GetValues functions.


In the GetValues (plural) the time context is defined as a AFTimeRange and I do can use the timeRange in my AFDataReference overloaded class.


In the GetValue (singular) the timecontext is passed as an "object" as it can be either a AFTime or an AFTimeRange.


The issue is that I get a null pointer exception when I try to cast the object to an AFTime.


In the VisualStudio debugger, I can see that tje timeconext is "null" while the parameter in the calling funtions AFAttribute.GetValue(AFTime) is properly set with and AFTime object....


Has anyone encountered this issue ?


Thanks in advance.
