I'm using Richfaces 3.3.1.CR2 in a Seam 2.1.2.CR2 application. I'm testing with Firefox 3.0.10, and recently installed the Web Developer Plugin 1.1.6
( https://addons.mozilla.org/en-US/firefox/addon/60 ). When running my app, Web Developer emitted several warnings that seemed to be Richfaces related. To check, I pointed my browser to the Richfaces Live Demo site, and received the same warnings. Most are related to org/richfaces/skin.xcss (e.g., unknown property warnings, error in parsing warnings, etc.).
I'm not sure if these are valid warnings or simply an artifact of Web Developer, but thought I'd raise the issue.
please feel free to rise jira issue with warnigns details attached.
