Re: [udig-devel] Removing ContextModel from the Project Model
The alternative is to keep the two lists in sync; which would be a bit sad / difficult. I am also concerned about loading previously saved uDig project files.

1. Most code has already migrated to the IMap.getLayerList() method
2. It should be easy enough to do a traverse of the LegendItem tree and produce an answer for getLayerList() however ...
3. Jesse is correct that there may be some event listeners that are watching for context model to change its list of layers
4. I think we need to keep ContextModel around for one more release;  and switch the rendering code over to listen to getLegendItems() changing. This also gives us a chance to load previously created projects; and notice if the ContextModel is non empty (and use it to define the initial list of legend items)

Good luck.  I think events is going to be the trickiest part.

As part of adding a legend view we have identified the possibility of removing the deprecated ContextModel from the Project Model.

This would result in quite a few changes across the Project Model but at this stage all I have done (locally at this stage) is add a list of LegendItems to the Map. This legend (list of items) will replace the ContextModel which stores a list of layers for the map.

Give us a yell if you can think of any issues that might arise from removing ContextModel.
