Exactly the same problem here!
I finally got mine to work. It may be overkill as I don't really know which action solved it but between the two following, it solved the problem for me:
1. To the source path under the build path options I added the following folder:
C:\Program Files (x86)\Adobe\Adobe Flash Builder 4.5\sdks\4.5.1\frameworks\projects\spark\bundles\en_US
2. In the library path I added
C:\Program Files (x86)\Adobe\Adobe Flash Builder 4.5\sdks\4.5.1\frameworks\locale\en_US\spark_rb.swc
Of course, your folder structure may be different. Let us know so we can pinpoint eventually.
Well it worked for a couple weeks and now it's back. Anyone else had success solving this?
I don't have a solution, but i think i pinned the circumstance down to being generated when:
- You have a localised project
- You also embed a generic (non-localised) asset
In the case I used to file a bug report, including/removing an <s:Image> tag causes/removes the problem:
Note: In my builder I had an additional issue making it difficult to pin down - in that once the Design Mode Problem had been raised, even reverting the line of code that caused it didn't clear the problem report - took a couple of odd steps:
