Dynamic nodes in Tree
Hello,
I have a wizard that in the last step I show a tree with the selections made
in the previous steps.
The wizard uses static steps so actually the last step is built in advance.
The problem is that the tree is not updated.
For debugging purposes I have in the last step tables that show the same
selections.
The tables are updated (the DataProvider calls the iterator). I use
DetachableModel for the tables.
So in short,
How can I updated the model of the tree.
Below is the code of creating the tree that is made in the constructor:
private TreeModel createTreeModel() {
final Profile profile = (Profile) getModelObject();
final DefaultMutableTreeNode rootNode = new
DefaultMutableTreeNode();
final ConfigurationsNode configurationsNode = new
ConfigurationsNode(profile,
getString("extract.rdb.profile.view.section.configurations"));
configurationsNode.addToParentNode(profile, rootNode);
final CampaignsNode campaignsNode = new CampaignsNode(profile,
getString("extract.rdb.profile.view.section.campaigns"));
campaignsNode.addToParentNode(profile, rootNode);
final UniverseNode universesNode = new UniverseNode(profile,
getString("extract.rdb.profile.view.section.universes"));
universesNode.addToParentNode(profile, rootNode);
final BprsNode bprsNode = new BprsNode(profile,
getString("extract.rdb.profile.view.section.bprs"));
bprsNode.addToParentNode(profile, rootNode);
final AuditCardsNode auditCardsNode = new AuditCardsNode(profile,
getString("extract.rdb.profile.view.section.audits"));
auditCardsNode.addToParentNode(profile, rootNode);
final AllTicketsNode allTicketsNode = new AllTicketsNode(
getString("extract.rdb.profile.view.section.allTickets"));
allTicketsNode.addToParentNode(profile, rootNode);
final TreeModel treeModel = new DefaultTreeModel(rootNode);
return treeModel;
}
Here's one of the nodes:
public final class ConfigurationsNode extends AbstractProfileDataNode {
private static final long serialVersionUID = 3306972776261689364L;
public ConfigurationsNode(final Profile profile, String title) {
super(title);
final List<Configuration> configurations =
profile.getConfigurations();
for (final Configuration configuration : configurations) {
final DefaultMutableTreeNode configurationNode = new
DefaultMutableTreeNode() {
private static final long serialVersionUID = 1L;
@Override
public Object getUserObject() {
return configuration.getConfigurationName();
}
};
add(configurationNode);
}
}
@Override
protected boolean isVisible(Profile profile) {
return CollectionUtils.isNotEmpty(profile.getConfigurations());
}
}
@SuppressWarnings("serial")
abstract class AbstractProfileDataNode extends DefaultMutableTreeNode {
private final String title;
AbstractProfileDataNode(String title) {
this.title = title;
}
@Override
public final Object getUserObject() {
return title;
}
public final void addToParentNode(Profile profile, final
DefaultMutableTreeNode parentNode) {
if (isVisible(profile)) {
parentNode.add(this);
}
}
protected abstract boolean isVisible(Profile profile);
}

OK. Found the solution:
private IModel createTreeModel() {
final IModel model = new AbstractReadOnlyModel() {
private static final long serialVersionUID = 1L;
@Override
public Object getObject() {
final Profile profile = (Profile) getModelObject();
final DefaultMutableTreeNode rootNode = new
DefaultMutableTreeNode();
final ConfigurationsNode configurationsNode = new
ConfigurationsNode(profile,
getString("extract.rdb.profile.view.section.configurations"));
configurationsNode.addToParentNode(profile, rootNode);
final CampaignsNode campaignsNode = new
CampaignsNode(profile,
getString("extract.rdb.profile.view.section.campaigns"));
campaignsNode.addToParentNode(profile, rootNode);
final UniverseNode universesNode = new UniverseNode(profile,
getString("extract.rdb.profile.view.section.universes"));
universesNode.addToParentNode(profile, rootNode);
final BprsNode bprsNode = new BprsNode(profile,
getString("extract.rdb.profile.view.section.bprs"));
bprsNode.addToParentNode(profile, rootNode);
final AuditCardsNode auditCardsNode = new
AuditCardsNode(profile,
getString("extract.rdb.profile.view.section.audits"));
auditCardsNode.addToParentNode(profile, rootNode);
final AllTicketsNode allTicketsNode = new AllTicketsNode(
getString("extract.rdb.profile.view.section.allTickets"));
allTicketsNode.addToParentNode(profile, rootNode);
final TreeModel treeModel = new DefaultTreeModel(rootNode);
return treeModel;
}
};
return model;
}
I knew it's something with dynamic model !!

Got it :)
The root is a class member and not created in the getObject(..) each time.
The TreeModel is class member as well.
I also had to removeChildren from the root at the begining of the method.

Still have a problem.
When I use the IModel instead of the TreeModel, in the constructor, the
nodes are not responding to the clicks.
Any ideas?
