Problems with Googlemap Lib & FlexBuilder

[Xantixts]

Hi,

Setup: Flex 3.2 - Builder
Googlemap-Lib: map_flex_1_19a.swc

In fact i want to use the googlemap lib as an rsl which is loaded from another server.
With the flex framework no problem. But i cant do it in the same way with googlemap lib.

Does anyone used the googlemap lib as crossdomain rsl?
My Problem is, that the lib seems to have no unsigned digest.
Or am i on the wrong way?

Thats my Error Message in FlexBuilder: No unsigned digest found in catalog.xml of the library,
/Documents/Flex-Workspace/Test-Viewer/lib_rsl/map_flex_1_19a.swc.
Compile the library with -create-digest=true and try again.

Many Thanks.
