The IDE tools need to catch up with the power of Seam. One thing for catching facelet file validity: I have a task in my ant build.xml file which creates an exploded EAR file. That is what I deploy during development. I have another task in the build.xml file which pushes all the current .xhtml file to the exploded EAR file. That way, if there is a mistake in a .xhtml file, I edit the file, save it, run the ant task to push the .xhtml out, and hit reload on the browser. Takes a few seconds and lets me check without needing to redeploy. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4075421#...
