I just checked in a major improvement to Tree2. Most users won't notice a difference but you will want to test your code to make sure nothing has been broken. The change should be available in the latest nightly build. It will *not* be in the upcoming tomahawk release that is due in the next two weeks.
The improvement relates to MYFACES-911 and consists of a proposal originally made by Mathias Werlitz's (with some modifications.) It provides much better support for *dynamic* trees. You are no longer constrained to the 0, 0:1, etc. node id scheme. You can provide your own TreeWalker interface now which is in charge of "walking" the data during rendering. The idea is that the renderer calls next() on the TreeWalker interface which sets the current node and returns a boolean value indicating whether or not another node is available. There is also the option to ignore the tree state so you can walk the entire tree regardless of whether or not nodes are expanded or collapsed. There should be no change to your existing tree2 JSF unless you want to take advantage of the new features. Everything is supposed to be backwards compatible. I added a few unit tests and went through the examples. There is one use case that is not working at the moment (hide root node) and I will fix that shortly. I'm hoping to start a discussion about the tree2 stuff with our now significant number of users. Over the next few days I will be trying to go through the old JIRA issues and commenting on them. I'm also looking to improve the documentation (although I could certainly use some help on that.) Stay tuned ... Sean
