Greetings,
Sorry to disturb your weekend. I cannot seem to get a
PickManiplulationRenderer to allow direct manipulation of my FlatField,
however, if I use a DirectManipulationRenderer it works fine.
Please see the attached code. In the line:
display.addReferences( pmr, dataRef );
if you change "pmr" to "dmr" the direct manipulation behaves normaly,
but when using "pmr" it does not. I thought that since
PickManiplulationRenderer extended DirectManipulationRenderer, that it
should behave the same way. It this correct? Is there something wrong
in my code?
Many thanks!!
-kevin.
