Bug 8808 Class folder: Must use create to add an existing folder
Build I20020129 "Add Folders..." does not show the project itself. I have to do the following trick to add an existing folder as class folder: Press "Create folder" Enter the name of the existing folder (hopfully it's in the project root :-) Voila BTW: I can't do this a second time - the UI tells me it already exists - which is OK. To be consistent with other dialogs "Create Folder" should always warn about existing projects.
