Hi
In wicket 6 this worked, there are another input field (ajax activated)
that triggers the update :

ChildAwareNestedTree profilePartitionTree = new
ChildAwareNestedTree("skillsetSelect", provider, sharedExpansionState)
{

@Override
protected Component newContentComponent(String id,
IModel<TreeNode> model) {

TreeNode node = model.getObject();

if (node instanceof TreeNodeProvider.PartitionNode) {
Partition partition =
((TreeNodeProvider.PartitionNode) node).getPartition();
if
(getPartitionsWithProfiles().containsKey(partition.getId())) {*
expand(node);*
}
} else if (node instanceof
TreeNodeProvider.NoPartitionNode && isNoPartitionProfilesPresent()) {*
expand(node);*
}

....}

The triggering field:

searchTerm.add(new AjaxFormComponentUpdatingBehavior("keydown") {

@Override
protected void onUpdate(AjaxRequestTarget target) {
if (searchTermModel.getObject() != null &&
!searchTermModel.getObject().isEmpty()) {
profilePartitionTree.rebuildExpandedPartitions();
} else {
profilePartitionTree.getPartitionsWithProfiles().clear();
}* target.add(profilePartitionTree);*

}

@Override
protected void updateAjaxAttributes(AjaxRequestAttributes
attributes) {
super.updateAjaxAttributes(attributes);
attributes.setThrottlingSettings(new
ThrottlingSettings(searchTerm.getMarkupId(),
Duration.milliseconds(400), true));
}

});

But I get an this error message in wicket 8, my line below:

Hi Nino,

during rendering of components no additional components can be added to the ART any more.

I surprised that your code worked in 6.x, can you build a quickstart demonstrating the problem?

Have fun

Yes I understand.. Let me see if it breaks in wicket examples, or I can
make it so.. Do you know another way to make a node/folder expand during
construction time? Feels like the expand method are meant for ajax calls
only.

Hi Nino,
during rendering of components no additional components can be added to the ART any more.
I surprised that your code worked in 6.x, can you build a quickstart
demonstrating the problem?
Have fun
Sven

Hi In wicket 6 this worked, there are another input field (ajax

activated) that triggers the update : ChildAwareNestedTree
profilePartitionTree = new ChildAwareNestedTree("skillsetSelect", provider,
newContentComponent(String id, IModel model) { TreeNode node =
model.getObject(); if (node instanceof TreeNodeProvider.PartitionNode) {
Partition partition = ((TreeNodeProvider.PartitionNode)
node).getPartition(); if
(getPartitionsWithProfiles().containsKey(partition.getId())) {*
expand(node);* } } else if (node instanceof
TreeNodeProvider.NoPartitionNode && isNoPartitionProfilesPresent()) {*
expand(node);* } ....} The triggering field: searchTerm.add(new
onUpdate(AjaxRequestTarget target) { if (searchTermModel.getObject() !=
null && !searchTermModel.getObject().isEmpty()) {
profilePartitionTree.rebuildExpandedPartitions(); } else {
profilePartitionTree.getP
artitionsWithProfiles().clear(); }* target.add(profilePartitionTree);* }
@Override protected void updateAjaxAttributes(AjaxRequestAttributes
attributes) { super.updateAjaxAttributes(attributes);
attributes.setThrottlingSettings(new
ThrottlingSettings(searchTerm.getMarkupId(), Duration.milliseconds(400),

currently unable to reproduce in examples, something must be wrong in my

I'll comeback if it turns out otherwise..

Thanks for helping :)

I've debugged a lot further. But still unable to pinpoint it.. For now I've
switched to rendering the full page instead, which of course works.

We are a couple of things in conjunction with TREE, like wicket jquery ui
draggable and droppable.. We also have a custom loading mechanism that pops
