问题
since I'm using custom skin classes in Flex I'm getting an error, when trying to open the design view in Flash Builder:
Description Resource Path Location Type
Unable to resolve resource bundle "components" for locale "en_US".
Unable to resolve resource bundle "core" for locale "en_US".
Unable to resolve resource bundle "effects" for locale "en_US".
Unable to resolve resource bundle "layout" for locale "en_US".
Unable to resolve resource bundle "skins" for locale "en_US".
Unable to resolve resource bundle "styles" for locale "en_US".
I tried a lot with setting locales in compiler arguments - but I thinks this error is directly related to a locale problem. When I check the flex framework directories "C:\Program Files\Adobe\Adobe Flash Builder 4\sdks\4.0.0\frameworks\projects\spark\src\spark" - here are the original skin classes located - I can see all the "missing" folders.
Anybody has a clue about that issue?
回答1:
I could solve my problem by adding following Library Path to the Project settings / Flex Build Path:
C:\Program Files\Adobe\Adobe Flash Builder 4\sdks\4.0.0\frameworks\locale\en_US
It seems that the Flex compiler knows the path when working with the standard skins but somehow it can't find it when dealing with custom skins.

If any issue like this type, means it can not found your file path
Go to Project --> Property-->Flex Build Path-->Source path-->Add Folder --> locale\en_US
which file error show on Description
here is additional source folder can be add outside of the main source folder

In addition to what the previous answers here already address, there is another possible cause.
This error appears also when a required locale is missing from the SDK itself. The list of existing SDK locales can be found at SDK.INSTALL.DIR/sdks/VERSION.NO/frameworks/locale. If a required locale is not there, then you need to create it with the copylocale command.
For more information, see Creating a new locale for i18N capable application.
