Bug 30005 Can't create linked source folder in new java project wizard [build path]
Build: I20030122 1) Open the new java project wizard 2) Enter a name, hit next 3) Click "Add Folder" on the "Source" tab. -> dialog comes up that doesn't have an option to create a new folder 4) Click cancel. Click "Browse" next to the output folder field -> this dialog allows you to create a new folder (even a linked folder) 5) Click cancel. Finish the wizard. 6) Open the java build path property page 3) Click "Add Folder" on the "Source" tab. -> now the dialog allows you to create a new linked folder. It should allow you to do this from the wizard.
