Error compiling stylesheets

[mark goldin]

I am getting the following error:

Invalid Embed directive in stylesheet - can't resolve source
'Embed(source = "../../assets/BlueOnWhiteStyle/Open_Normal.svg")'.

Code in css is this:.caseLibraryIcon{

        image:  Embed(source='../../assets/BlueOnWhiteStyle/Open_Normal.svg');
}

Code in my mxml file is this:

_caseImage.source =
StyleManager.getStyleDeclaration('.caseLibraryIcon').getStyle('image');


Everything works, but build server fails with the above error.

Any idea?

Thanks
