David:
Thank you so much for your prompt response (you certainly are busy and
responsive!). I even tried using 'ex:itemTypes = "Milestone"' (which works
on lenses) on the timeline view in the hopes of switching to a root of
Milestone (also, see below with regard to the timeline constructor, I also
tried a call to 'myExhibit.setRootTypes("Project");' after instantiating a
"myExhibit variable" but that just confused Exhibit). I can live with the
situation (I'll take the bars labeled with the "project) but:
In your problem 2, the timeline still thinks it's plotting projects (not
milestones). So if you click on any bar in the timeline, the lens that
shows up renders the project, not the milestone. So all the expressions
are relative to the projects.
Given that situation, is there any way, in the lens, to tell which of the
milestones (my assumption here is some sort of set represents that
collection of milestones - they show up nicely when referring to the
collection, I just need to know which one is currently being processed) is
currently being rendered? I can't quite figure out the correct expression
given the project as a base. Can you give some definition of the "index"
path element (I suspect this is what I need - the "index" of the particular
milestone being processed)?
Also, I'm already using the trick of including (and have working) the
timelineConfig/timelineConstructor to setup the timeline, so I would not be
adverse to including another <script> </script> section if you can recommend
some javascript to override a function or two to get me closer to my goal.
Thanks again.
Charles
