I have a problem with LinkTree in Wicket, namely :
I have a LinkTree where NodeComponent a TreeLinkIconPanel is.
TreeLinkIconPanel is a subclass of LinkIconPanel.
public TreeLinkIconPanel(String id, IModel model, BaseTree tree) {
super(id, model, tree);
}
Where a content as a label and image as a normal Icon:
protected Component newContentComponent(String componentId, BaseTree tree,
IModel model) {
...
if (model.getObject() instanceof ProcessNode) {
lLabel = new Label(componentId, ((ProcessNode) model.getObject())
.getName());
}
...
return lLabel;
}
@Override
protected Component newImageComponent(String componentId, BaseTree tree,
IModel model) {
Image lImage=(Image)super.newImageComponent(componentId, tree, model);
if (model.getObject() instanceof ProcessNode) {
lImage = new Image(componentId,((ProcessNode)model.getObject
()).getState());
}
...
return lImage;
}
The model is not updated, when the Tree to AjaxRequestTarget added.
And when ClickEven must this tree, in my case image the tree's, refresh
But what is not done:
protected void onNodeLinkClicked(TreeNode node, BaseTree tree,
AjaxRequestTarget target) {
super.onNodeLinkClicked(node, tree, target);
if (node instanceof ProcessNode) {
((ProcessNode)node).setStateGreen();
fireProcessClickEvent(target);
} else if (node instanceof ActivityNode) {
((ActivityNode)node).setStateYellow();
fireActivityClickEvent(((ActivityNode) node).getName(),
target);
}
}
Here, this event is received:
tree.addTreeListener(new TreeListener() {
@Override
public void onActivityClicked(String nameOfNode,AjaxRequestTarget
target){
...
target.addComponent(tree);
}
@Override
public void onProcessClicked(AjaxRequestTarget target) {
...
target.addComponent(tree);
}
});
But if I befor the tree, the new model set, then it works:
tree.addTreeListener(new TreeListener() {
@Override
public void onActivityClicked(String nameOfNode,AjaxRequestTarget
target){
...
tree.setModel(new Model((Serializable) new DefaultTreeModel
(processNode)));
target.addComponent(tree);
}
@Override
public void onProcessClicked(AjaxRequestTarget target) {
...
tree.setModel(new Model((Serializable) new DefaultTreeModel
(processNode)));
target.addComponent(tree);
}
});
It is of course not as nice and not so expected.
If someone can help me - that would be very nice.
Thanks in advance.
