Editing a Tree of Data...

[James Carman <ja...@carmanconsulting.com>]

In our application, the users want to be able to construct their own
ad-hoc summary tree out of rows of data from a table.  They want to
select the rows and do something like "add to my summary tree."  Then
it would take them to a screen where they can edit that summary tree.
The operations we need to be able to do are:

1.  Move nodes around within the tree (moving to subnodes of an
existing node and being able to re-order nodes within a node).
2.  Create their own nodes that can be containers/folders/categories
for other nodes.
3.  Remove nodes.

How would you guys go about doing something like this in Wicket?  Do
you think the drag-and-drop support is rich enough to allow for this
type of functionality?  Would it be worth it (I could potentially put
this stuff in our Swing client piece of the application if need be)?

Hi James

You can get very very far just using listboxes and checkboxes, unless 
the customer wants the tree for the tree's sake..

checkout http://www.jobindsats.dk/sw167.asp select databank (I know it's 
danish, and don't mind asp extension it's really wicket behind)

Otherwise I'd try to go with drag and drop as it are, and if it were too 
bad i'd fix it:)
