[udig-devel] Re: Maps and LayerViews across multiple WorkbenchWindows

I think I'm good in explaining things in a way that makes them sound much more
difficult than they are :-). Actually, I don't want the maps to track the same
area! We don't need any interaction between them such as joint panning or
zooming by now. With "using layers partly distinct" I simply tried to say that
there are some geoResources which will be used by all maps (e.g. administrative
boundaries) and some which will be used exclusively by any of the maps. E.g.:
Map 1 contains the "administrative boundaries" layer and the "sensor
observations" layer. Map 2 also contains the "administrative boundaries" layer
(but doesn't necessarily show the same area) and a "rivers" layer.

So maybe I do not see the wood for the trees. I just want to have multiple maps
(being independent from each other) opened programmatically in multiple windows
in a single application. In addition, each window shall have an independent
LayersView. How is this manageable with the current uDig framework?

This is what I wondered - if there is already a solution for my use case (on
the basis of your comments I assume there is one).
I'm also not sure, if we'd need an "Open with..." functionality. Rather
an "Open in window..." functionality.

However, this sounds interesting for the case that I would like to have the
maps in sync in the future. I think it would also be possible to use
ViewportListeners by the editors. The "sync viewport" solution would also be
good since we use WGS 84 throughout the application.
Once again, thanks for your support!
