Flex Builder 3 warning: “CSS type selectors are not supported in components”

Posted by: Kenneth in Flex, Work, tags: components, css, FB3, Flex, Flex Builder 3, mxml, stylesheets

I have been seeing this warning ever since i switched over to FB3. The moment FB3 went live, i did not have the luxury of doing a proper migration. Everything was pretty much in FB2 version and as long as it worked, nothing else matters.

But yesterday, seeing 600+ warnings was an eyesore compared to this:

What i have done is to remove all these from all my components and leave all the stylesheets declarations at the Application mxml.

<mx:Style source=”/location/to/some/Style.css”/>

Found the solution from here.

You might wanna check one of your css files. The error may exist because you are missing a ‘.’ to the left of one of the items that you declared there.
For example the following css declaration will throw an error:
FormHeading{ paddingTop: 15;
}

To fix this, all you have to do is:
.FormHeading{ paddingTop: 15;
}
