I've just started trying to use CVS within IDEA 3.0. I have a hierarchy of files that are checked out and inside a "web application". When right clicking on any of the files, the CVS menu presents "add" and "checkout" as the only CVS command options.
I'm pretty sure that I can access CVS though because I can perform a CVS checkout into another directory from within IDEA.
To add a little more strangeness check the following out:
1) unzip a clean copy of tomcat 4.1.12
2) from within IDEA checkout my web application into ]]>/webapps
3) add the web application to my current project
These steps will show the checked-out directory hierarchy under webapps in the "web" interface/tool/whatever, but no actual files are shown. They're definitely there though, I checked.
