Description John Lanuti CLA 2006-03-06 10:24:07 EST 
Opened for Rajasimhan A Mandayam of IBM

The Project Explorer takes a long time to expand the nodes (it takes long the first time because of incredible
number of plug-in activations, )

Try expanding the nodes in WTP (Dynamic Web Project, EJb project, Enterprise...) 

Even after that try expanding a project node it takes time.

Its a generic problem for which has Eclipse has a soln in place from 3.0, 
Lazy tree expansion

The DeferredTreeContentManager is already in place in eclipse

I am sure the Project Explorer guys may have already encountered this solution before, I am not sure
why they have not implemented it.

By playing around with it I have implemented it in the project explorer in my workspace,
its not too hard, I only had to implement 2 classes and make a couple of changes here and there.

The treeviewer expands very quickly and is more UI responsive.

Let me know if you need any info.
