Just my 2cents:
As far as I understand one of the main features of Telescope are “Visualizations” that
essentially are models that you set up and then they spit out a view on demand. Now
builders in Roassal were designed to be the same. Here is the first page of agile
visualization book, that is about builders and was first written as an IWST paper that was
not accepted:
http://www.slideshare.net/GuillaumeLarcheveque/telescope-introduction-and-e…
<http://www.slideshare.net/GuillaumeLarcheveque/telescope-introduction-and-example>.
It tells that there is a #renderIn: method that should be overwritten by a builder
developer and which accepts and view and does what the builder should do.
Now some time after this documentation was written, people started develop “stateless”
builders that don’t collect all data but instead instantly draw something. I started to
complain about this already at that time… Now as I see a situation now is that Telescope
is a part of Roassal that Roassal voluntarily refused to be. From my point of view the
only reason to do this stateless builders is because they are easier to implement, you
don’t have to create single building method and so on. Otherwise they are much harder to
use because you have to remember order.

Hi Peter,
The paper is not the best way to see what Telescope is able to.
Look at the demos and the presentation Anne did at Esug:

I don't know exactly what are your problems but if it is to create really high level
visualizations with lot of interactivity, Telescope is definitely the good tool to use.
That was my understanding so I wanted to look at it. But without any documentation it was
hard for me to even begin.
Usman Bhatti posted in another thread link to a Telescope paper, so I'll read it
tomorrow and hopefully it will give me a little bit of insight.
If your problem is about visualization but not yet managed by Telescope; ask me and I
will look at it.
Well we have already heavily invested in Roassal and this is not going to change, since
we are continuing to work even on quite low level stuff (like bendable lines, elements
resizing, attach points, ...).
But I wanted to see, if Telescope could help us with some high-level abstractions, which
are currently quite painful for us. I even started implementing some Eclipse GEF ideas...
So I'll read the paper and I'll see...
Peter
