Joern Kottmann commented on UIMA-2252:
--------------------------------------
Here is also an article which explains how it works:
http://www.eclipse.org/articles/Article-WorkbenchSelections/article.html
Usually you want to check that it is a StructuredSelection and then you might
want to filter
out anything which is not an annotation, that can be done with the
AnnotationSelection class,
have a quick look at it and search for a usage in the Cas Editor code base.
Can you elaborate a bit ont eh caret position. In the Annotation Editor there
are also ways to select a piece of text which do not change the caret position.
If you just look for caret position changes you miss these. Thats why I
believe you usually want to know about the text selection (includes offsets in
the editor).
In eclipse there is an ITextSelection, would that solve your problem?
