ECSS parser is too aggressive when encountering non-standard CSS properties: selector omitted entirely ------------------------------------------------------------------------------------------------------ Key: RF-11741 URL: https://issues.jboss.org/browse/RF-11741 Project: RichFaces Issue Type: Bug Security Level: Public(Everyone can see) Components: skinning Affects Versions: 4.1.0.CR1 Reporter: Karsten Wutzke Labels: ecss, parsing, skinning Fix For: 5-Tracking When defining rules like {code} .shadow { -webkit-box-shadow: 4px 4px 5px '#{richSkin.additionalBackgroundColor}'; -moz-box-shadow: 4px 4px 5px '#{richSkin.additionalBackgroundColor}'; box-shadow: 4px 4px 5px '#{richSkin.additionalBackgroundColor}'; } {code} in an ECSS file to create skin-dependent drop shadows, RF 4 will omit the above rule entirely and no shadows will be rendered. BTW it would be better to just omit the invalid properties instead of the entire selector (box-shadow: ... alone works). Most browsers don't support the box-shadow yet, so defining proprietary properties *must* be possible. Note, this applies to a lot more properties than the above.
