source: josm/trunk/src/org/openstreetmap/josm/gui/dialogs/RelationListDialog.java@ 3146

Last change on this file since 3146 was 3102, checked in by Gubaer, 14 years ago

fixed #4651: Ability to download incomplete relation from selection
fixed #4098: Popup Menu entry "download relation members" in relation dialog should be "download incomplete relation members"
fixed two NPEs in RelationListDialog and SelectionListDialog
refactored SelectionListDialog to support better user feedback (enabled/disabled buttons and menu items)
Finally removed the sort() method on DataSet, marked as FIXME since a long time.

CAVEAT: DataSet.getSelected() now returns an unmodifiable list instead of a copy of the selection list. This may lead to UnsupportedOperationExceptions in the next few days. I tried to make sure the JOSM core uses getSelected() only for reading, but I didn't check the plugins.
