In the init event of a subclass of the custom object from _base.vcx, I have the following code:

this.addobject("de","dataenvironment")
this.de.addobject("cursor1","cursor")
this.de.cursor1.alias="custs"
this.de.cursor1.cursorsource="customers"
this.de.cursor1.database="cc"
this.de.cursor1.nodataonload=.f.

I get the error:
"Object class is invalid for this container" upon attempting to instantiate the dataenvironment object.

I have tried using the container class instead of the custom class with the same results.

I heard this can be done. Does anyone know what I am doing wrong here?
TIA
