ICEfaces + Eclipse + Seam

So, I got tired of looking up ICEfaces tags in the documentation, and downloaded the ICEfaces plugin for Eclipse from here.  Then I tried to use the code completion feature.  No dice!  According to this bug, it's broken, and isn't likely to be fixed soon.  Ouch.   And I thought it was going to be smooth sailing.  Apparently this has been a problem since at least 2006.  The best thing I could do is to rename the "xhtml" files to "jspx".  Hope that Seam still works after this :(
