Simple error in configuration

Question

Folks,

I' am getting below error :

Design mode: (reason: ERROR: Load Verify). It may require classes (such as Adobe AIR components) that are not supported by design mode. Check the Eclipse error log for more details. Main.mxml "Design view" Problem

What could be the problem ?

Answer 1

As kyohiro said, it is a known issue. Note: It is a warning, not an error. Your project should still be compilable and runnable.

Answer 2

Seems that this is a known issue:

Good find.
