Description dbell 2011-10-03 10:21:52 UTC 
[ BUILD # : 201109260601 ]
[ JDK VERSION : 1.6.26 ]

In NetBeans module projects, loading of "<this layer in context>" (under XML
Layer in the Projects tab) is very slow. It appears to load all of the virtual
filesystem at once, making it very fast to navigate, but slow to first open. It
would be great if it could lazily load the context view nodes, so that it
doesn't take so long to initialise.

Correct - layers from all modules in the application are loaded.

> lazily load the context view nodes

I doubt this would help much; you would get an inaccurate view quickly, and then probably more time would be wasted firing change events as other layers are inserted.

There is already a platform layer cache which should help with subsequent displays.
