Created attachment 123917 [details] .form files shown in "Projects" window .form files for java gui shown in "Projects" window. See pic for prove. Before that I switched to "Files" and browsed that files.
I've seen this a few times as well, but have never found a way to reproduce it. Have you? The picture shows that the nodes for the form data objects are there (with the .java extension), including the correct icon. They also work on opening, etc. The only problem is the additional nodes for the .form file. Looks like some race condition in recognizing the data objects or in creating nodes for them. It can be seen when expanding a package/folder with many forms that all the nodes both for .java files and the .form files appear first for a while, with unrecognized icons, then the .form nodes are removed and the .java nodes get the right icon. Seems this can sometimes get broken... I don't think this could be caused on the GUI builder side. Reassigning if someone has an idea...
I've seen this as well. I need a memory dump next time you see the problem... *** This bug has been marked as a duplicate of bug 202614 ***
