Morning Robert,
Thank you for your note.
I tried each suggestion, and for some reason, I just can't get any layer to draw when it's a type="feature".
All services are visible in ArcCatalog. Seem to work fine, I can see them, 'info' them.
I agree, this is not an issue with any widget coding.
Any other suggestions by chance?
I'm using Flex 2.4, perhaps try the 3.0 version?
Might be time to contact ESRi support.
