I gave up using the Seam and richfaces implementations in the Jboss DevStudio 1.1.0 Beta 1 and am now using Seam 2.0.2.SP1 and richfaces 3.2.0.SR1. The issue is pretty simple: In richfaces-ui-3.2.0.SR1.jar and earlier versions, there is an \org\richfaces\taglib\inplaceSelect tag. There isn't one in the richfaces ui jar that is included in the DevStudio beta. So any facelets files that use that tag are failing when run in DevStudion beta 1. Is that an oversight, or is inplaceSelect coming back? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4158496#...
