I have a custom treeviewer which extends composite and has treeviewer as the class member, which is hooked up with a content provider, label provider and a sorter. Whenever I sort,
though the input gets sorted, it produces multiple rows of existing elements.
Has some one encountered the same problem???
Look for a bug in your sort implementation and/or your content provider. TreeViewer will only display duplicates if the duplicates are fed to it by the content provider.
