Ok. Well, I don't see any reason why it shouldn't work and I tested it,
so I think we're fine. It'll be in 1.0.1 and 1.1b1.
It seems that AbstractTree.java has choosen a selectionmodel with single
selection:
treeSelectionModel.setSelectionMode(TreeSelectionModel.SINGLE_TREE_SELECTION);
that makes it hard for me to make a selection tree as only the latest selected
path in tree is avialble....
I tried with another selection model:
treeSelectionModel.setSelectionMode(TreeSelectionModel.CONTIGUOUS_TREE_SELECTION);
But i still only get the latest selected path when i run my debugger
selectedPath: javax.swing.tree.TreePath =
[EMAIL PROTECTED]"[Kategorier, T%F8j%2Fsko%2Fpersonlig+pleje,
Wagner]"
selection: javax.swing.tree.TreePath[] = null ???????????? this should be
set ???
And here is the code onsubmit:
TreePath[] selectedPaths =
categoriesTree.getTreeState().getSelectionModel().getSelectionPaths();
if (selectedPaths != null) {
for (int i=0; i<selectedPaths.length; i++) {
log.info("selected path:" +
selectedPaths[i].getLastPathComponent());
}
}
Any ideas ?
Nope, not at this time, sorry. The Tree component is pretty hard to get
right, and one of the things I presumed was that you'd usually would
only have one selection in a web application. I guess when you work with
checkboxes etc, that could be different, but I'm not sure how that would
work together. An alternative strategy would be to just use the tree for
rendering, and put a form around your tree and do something usefull with
the checkboxes or whatever you use in it. That's probably even clearer
than forcing it in the tree model.
If you have ideas they are welcome ofcourse. Tree is pretty usefull for
a lot of usecases right now, but it will take a few iterations before it
is 'perfect'. Took a long time in Swing for sure.

Ah, yes. I understand now. Sorry about that stupid bug.
I solved it a bit differently by providing a class that does nothing at
all (except being a panel) and a class that has the default components:
NodePanel and DefaultNodePanel. DefaultNodePanel is used by default, and
is the panel you can extend if you don't want to add your own component
structure, but just want to provide (slightly) different markup. If you
do want to provide your own components (like you do), you should extend
from NodePanel directly. As NodePanel itself just extends Panel, but
does not add any components, you can extend this and use it like any
other panel.
I have included the altered tree source file. Could you please confirm
that it solves your problem?
