Now my section is built with Seam and RichFaces. Here, some RF components are showing "borders". That is the case in a "spacer", which should be invisible and within a "extendedDataTable" in the headers where the sorting icons are located.
As you can imagine, that doesn't look good. Screenshots:
My guess is that the external CSS's are causing that... Since I cannot change the external css files: any idea if I can set a style to overwrite that border?
