I just noticed something strange. When I open the outline, couple the outline with the text editor (with the double arrow icon) and then select an item from the outline tree, the corresponding selection in the editor is sometimes unexpected. For example when in VHDL I have the following line:
The corresponding (somewhat simplified) grammar rule is:
PortElement:
names+=PortName (',' names+=PortName)* ':' (mode=PortElementMode)?
subtype=SubtypeIndication;
I would expect that if I click on the "clk" item in the outline, the "clk" (which is the string that corresponds to that item in the editor) is selected. Instead, only the ":" keyword is selected? Often the selection is what I expect it to be but not always. Is this intentional or should I file a bug?

Hi Mark,
this is intentional. The default implementation of the
ILocationInFileProvider tries to find the name of the element. If it has
no name (like your PortElement), the first keyword is selected that
belongs to the production rule that created the element. You'll have to
customize the location in your own ILocationInFileProvider.
Regards,
Sebastian
