Maybe I've been spoilt with the Flex components then, but I don't see why it's so hard to have a tree component use an XML file  as data provider, rather than insisting on a particular format. XML is just a tree after all, but anyway...

It would be good if it did xml or json. I also think there's quite a bit of detail in the existing wizard: the overall concept isn't difficult: display the tree, select a node, render the form...

We'll need to transform the data - you'll never get that lucky!! For one you are using a kind of non standard xml node structure <pagetype vs <page type=pagetype

I think jstree is the way to go though. I've been playing around with some possible editor code but have loads of questions and think we should be careful not to code ourselves into a corner with the editor that will be labour intensive to get out of.

Also, are you fixed on staying with xml data format? I know we need to be able to handle it to cater for old LOs but should we save out new ones in JSON also? Most of xeniths load time is probably parsing the xml. JSON would be ready once loaded.

Anyway there array lots of things to consider going forward. Should we start a v2.1 ideas list and then we can pick what we think we can achieve by summer? Html5 editing might be 2 or 3 versions away yet...

Ah, that's right: some of them use an html list as the data provider and I couldn't see how that would work for us without a lot of transformation. The other problem, if I recall, was that the ones that used XML needed the nodes to be a named a certain way, and again if I remember right, there wasn't one that could take *any* xml as a data provider.

I think that was the one that looked closest. There were three candidates if I recall, but I can't remember which ones they were. I didn't have time to explore some of the details, like events and how dataProviders work, but it looks like a good candidate for some more exploration.

I know you're thinking about the wizard - there's quite a lot of detail in the code in there, but essentially it's not a complex thing.

Julian,

You mentioned that you have been looking at javascript tree views to use in future work.

By chance I encountered this one: http://www.jstree.com/

Packaged as a jQuery plugin. Is that one suitable? If not, why not (it will enable me to look for a more appropriate one).

Tom
