In #1120 a exploded directory or war file is required. Why do I need it ? I don't want to have another directory created. I use my web resource Root Directory as "exploded" directory. This worked very well before #1120:
I wrote the path into the exploded directory textbox and deactivated "Create web module exploded directory". IDEA used the settings there.
If I have to do jsp-page manipulation in an exploded directory to see the changes in "real-time" and after that synchronize it with my "real" web-directory then I have much to do which is not very comfortable.
It would be fine to declare a exploded directory without the need to create a new dir.
