There are ${6 + 2} bears in the cave !! !!Comment ….
Having to use Tomcat outside the IDE is a kludgy way to preview your work … any suggestions (other than putting the EL in attribute values)? Is this a limitation of Eclipse or the MyEclipse plug-in? If so, will it be corrected in a future release?
You are correct the preview panel does not evaluate expressions. I don’t know that supporting that is comming in a release anytime soon as EL expressions can get quite complex and embedding a real-time processor to parse them, while not having a running container is not going to work. For simple examples like this it’s ok, but for examples more complex it could be a real bear.
