This is very similar to issue 144718. Repro: 1) Select and expand a source folder which contains some hidden entries such as a CVS sub-folder or .#* files. 2) On the folder, choose New -> Java Class... (for example) in the context menu. 3) Press Finish. The result is that all the hidden entries are shown as blank items for a second or so, which as in issue 144718 creates an unpleasant visual "bounce" effect, which gives the false impression that there's much more going on than just a simple file being created. Product Version: NetBeans IDE Dev (Build 200810181401) Java: 1.6.0_04; Java HotSpot(TM) Client VM 10.0-b19 System: Windows XP version 5.1 running on x86; Cp1252; en_US (nb)
PS: As with issue 144718, this seems to be only reproducible once for any given folder (per NetBeans session).
Same effect when deleting a file. I just had this hapen to me on a folder with ~30 hidden files, which looks atrocious as almost the whole treeview appears to be replaced by a long list of blank items for a second or two.
I guess reporter talks about projects view, but this looks to me as general explorer issue, passing there, please reassign if I'm wrong, thanks.
Both in Files and Projects view. Generally I work more with the Files view than with the Projects view.
This problem was probably introduced in 93a01020bf5a where FileObject was replaced by FolderChildrenPair which is used as key for FolderChildren. The problem is that each time setKeys() is called, the key for hidden file (e.g. file beginning with .) is different (seq. number in FolderChildrenPair is increased). It should be resolved by fixing issue 150747. *** This issue has been marked as a duplicate of 150747 ***
