LinkTree : when using a refreshing model, expanding/collapsing nodes
not working anymore
Hi
I've another issue with the LinkTree.
Up to recently, it was working all fine. I was creating the LinkTree this
way :
new LinkTree("tree", getTreeModel())
But then I wanted the model to be refreshed at each request. I tried with
many refreshing models like for example new LinkTree("tree", new
LoadableTreeModel(rootId)) or new LinkTree("tree", new PropertyModel(this,
"TreeModel"))...
However, each time, the expanding/collapsing behavior doesn't work anymore.
When I click on the + or - nothing happens.
Any help regarding what to do/where to look is highly welcomed !
thanks in advance

Did you ever get anywhere with this? I have the same problem where I refresh
the tree from the source data each time getObject() is called, that is, when
a user selects a node. It just feels wrong but I can't get it to work any
other way.
I am persisting selected nodes by implementing my own ITreeState then
overriding isNodeSelected(Object node) to check for the node in the source
data.
I think this methodology is what is preventing the expansion and collapsing
of node to fail (I think it's actually working but the tree rebuild is
refreshing it immediately)
Cheers,
Mark

hi
I didn't manage to sleep this night so I did a quickstart project with my
issue and then... realised how stupid I've been : when refreshing the tree I
loose the data about what to open/close, hence my issue.
I don't know yet the solution I'll follow, hesitating between informing the
user and refreshing the whole tree as soon as data behind change or keep
track of the tree state in some wrappers around my data.
Time'll tell, and hopefully my brain will be faster next time :)
Side node : I'm once again amazed by the flexibility of wicket. It's really
able to fit anyone needs.
The only "issue" with this tree, in my case, is that I find the code is a
bit clumsy. First I affect the data to the nodes (using recursion), and
then, when the linkTree is created, I assign some state to it according to
some specific nodes I've just added (like which one will be first the first
one, or to expand some nodes in order to have one pre selected), being kind
of required to keep track of them in between.
thanks again

Small extra precision : using tree.getTreeState().expandAll()/collapseAll()
works fine...
