TaiPan and EditingDomains [message #148887]

Can anybody explain why the Taipan example does not used shared editing
domain ids? What are the concrete effects resulting from this decision?
Would be nice if anybody could bring some light onto this and tell us
the reasons for using shared editing domains or not.

Using shared EditingDomains means, that multiple editors are working
with the same ResourceSet instance. The advantage is, that one editor is
able to reflect model changes made by another editor immediately
(without saving).

Using different EditingDomains means, that each editor works with his
own ResourceSet. This way editors can't receive notifications resulting
from changes made by other editors. The user has to save the model, so
that WorkspaceSynchronizer can do the synchronization job.

I prefer the second solution, because the first one means, that changes
made in one editor would dirty all other editors. I think users wouldn't
expect that.

What gets synchronized here? Ex: say I create a "Book" in one editor,
and then a "Book Category" in another editor. Save both. Can the Book
object now relate to a Book category?

This would truly solve my biggest issue at the moment :)

DocumentProvider reloads changed resources.

Did you try this? This should not be an issue. I assume both editors are
using the same model file. So adding an element in one editor and
performing save would force the other editor to relaod the model (and
"see" the new element).
