Authoring Eclipse plugins. Actions and views help.

Thread view:

I'm new to how to work with actions and views as related to writing
Eclipse plugins using SWT and JFace.

What I am attempting to do is have a tree that creates/updates a view
when a leaf is selected.

I've been experimenting with code and I've gotten a view to show up on
the first click of a leaf, but it doesn't update the data on subsequent
clicks of other leaves.

I'm experienced in Java, but totally new to GUI work. Any help would
be greatly appreciated. Thanks!

the key is you have to keep firing events to let Swing know which
nodes need to be repainted. It is up to you to track that.

TreeModel.fireTreeNodesChanged(...);

Sounds a bit like a cross-cutting concern, you might want to look at
AspectJ.
