问题
I can import the Play2 project in eclipse, and work on scala files, but the problem is I can't open view files likes 'index.scala.html'. When I try to open the file I get following error.
Could not open the editor: Editor could not be initialized.
java.lang.NoClassDefFoundError: scala/util/parsing/input/Positional

But there is no problem opening other files. I don't know what's wrong. btw, I used typesafe-activator to create play project.
I will appreciate any suggestions, solutions or workarounds to make it work.
Thank you.
