Hi
There is a filter for css files that scans for expressions, but it is only
enabled if type is text/css (at least in MyFaces).
I guess it should be something related to that core. In MyFaces the filter
is located in Resource.getInputStream() implementation.
The javadoc of Resource.getInputStream() says this:
"... Any EL expressions present in the resource must be evaluated before
serving the bytes of the resource. Note that due to browser and server
caching, EL expressions in a resource file will generally only be evaluated
once, when the resource is first served up. Therefore, using EL expressions
that refer to per-request data is not advisable since this data can become
stale. ..."
If you need to override this code, a ResourceWrapper checking for
getContentType() can do the trick.
