Hints needed for tree widget

[Dev at weitling <de...@weitling.net>]

Hi y'all,

I'm stuck with creating a tree widget. One problem: I want to display
some xml (I got out of a database) as tree. How to do it? I could write
a Java class, of course, but isn't there a standard way from the nice
guys from Cocoon?
And: Did I get it right, that here is no binding at the moment?

Thanks and greetings,
Florian

We've had this problem before at work. For a pilot project I managed to create
a tree widget that can be initialized with an XML document from an
URI. Unfortunately this widget uses an extra jar (xom) to parse the xml
content and cannot use 'cocoon:...'  references, only 'file:///...' or
'http://...'. I'm not proud of the methods used to produce the tree. But the
thing works and since it's only a pilot, I did not want to spend too much time
on it. I've tried to make the widget more cocoon-like, so it could parse sax
events et cetera, but it was very difficult for me to understand the cforms
stuff. Furthermore the tree widget code is not set up like other
widgets. Sylvain Wallez did create a beautiful thing with the tree widget. I
can understand why it is difficult to make it behave more like other widgets,
like the selection list for example.

No, there's no binding.

If you still want to try this tree widget that reads from an XML document,
send me an e-mail and I'll send you everything you need.
