I see the below css generated, here i did not find the image colHdrGrad.png anywhere in the jar file. I guess because of this i am, not getting the background color.

*.rf-edt {

overflow: hidden;

background-color: #FFFFFF;

border: 1px solid #C0C0C0;

}

*.rf-edt-hdr, *.rf-edt-tbl-hdr {

background-image: url(/RichfaceLiferayDemo/rfRes/colHdrGrad.png?v=4.0.0.Final&db=eAFjZJBjZDBiZBBh!H!y7QfG!00nzzMwAQA3dwcq&ln=org.richfaces.images);

}

*.rf-edt-tbl-hdr {

border-bottom: 1px solid #C0C0C0;

}

*.rf-edt-b {

overflow-x: hidden;

overflow-y: auto;

width: 100%;

}

*.rf-edt-spcr {

height: 0px;

font-size: 0px;

}

*.rf-edt-ftr, *.rf-edt-tbl-ftr {

border-top: 1px solid #C0C0C0;

background-color: #cccccc;

}

*.rf-edt-ftr-fzn {

vertical-align: top;

}
