FeatureLayer does not scale to changes in map scale

Featurelayer is not behaving as expected in release build when applying a DefinitionExpression and using either MODE_ON_DEMAND or MODE_SNAPSHOT.

FlashBuilder 4:
- Works properly in debug build
- Does not work in release build

The featurelayer:
mode = MODE_ON_DEMAND // MODE_SNAPSHOT - neither update when map scale changes
contains points. On demand should reapply definition at new extent. Snapshot should have fetch all features for the layer.

The workflow:
Map is zoomed to a county boundary. A definition query is applied to the featurelayer based on some criteria. Features in visible extent are correctly returned and rendered.

Zoom in or out 1 or more levels and featurelayer DOES NOT refetch features or properly scale itself. The layer just never updates. It does pan correctly though.

See screenshots attached.

It is strange that you're seeing a difference between debug and release builds. It may be a security issue. What are the url's you're using when you run each build? Can you provide source code that duplicates this issue?

Debug: using ASP.NET development server
http://localhost:3000/PublicViewer/flex_bin/index.html

Release: IIS
http://localhost/txwrapr/index.html

Can you provide source code that duplicates this issue?

I can send you the source offline if you provide me an email. Let me know...
