I've implemented a code editor for Eclipse that works great, but whenever I save its contents it puts the cursor and scrolls to the top. I want to remember the cursor and scroll bar position when the editor contents are saved just like the Eclipse Java editor does. I overrode AbstractTextEditor#performSave, AbstractTextEditor#performSaveAs, and AbstractTextEditor#editorSaved, calling AbstractTextEditor#rememberSelection and AbstractTextEditor#restoreSelection as a workaround. That saves the selection, but not the scroll position. I bet the framework can handle that, but I can't figure out how. Please help.

Saving should not change the current selection. I assume that you do
something wrong when saving the file e.g. setting the editor's
input/document or something like that.
