In project tree, use context menu to invoke "New->Spring config" In the dialog, select the following options:

• File name: "test"
• File set: "<new fileset>"
• Schema: "Spring 1.x DTD"

In the next dialog ("New Fileset Name") enter "test" as a name for the new fileset. So far everything looks fine. Now try to repeat the sequence. The second time around, I see invalid values in the "File set" dropdown (see screenshot). It looks like the previously generated fileset (using "<new fileset>" option) is being represented with invalid label ("<new fileset>" instead of expected "test").
