why is DefaultNestedTree component treated as property within PropertyResolver ?
Hi,
I'm trying to display a DefaultNestedTree (id="dataTreeView") within a
Bootstrap Modal
Instances of Service contain an ID that I use for retrieving a recursive data
structure from database.
The recursive structure is realized by instances of "RecursiveData" .
See line 15 and method onModelChanged().
RecursiveData contains self referencing properties "parent" and "children"
00 import com.example.Service
00
01 public class DataViewDialog extends Modal
02 {
03 private static final long serialVersionUID = 7766394608644043929L;
04
05 @SpringBean
06 private RecursiveDataBean dataBean;
07
08 private RecursiveDataTreeProvider treeProvider;
09
10 public DataViewDialog(String id, IModel model)
11 {
12 super(id, model);
13
14 Service service = model.getObject();
15 List data =
dataBean.getRootDataByServiceId(service.getServiceId());
16
17 BootstrapForm form = new BootstrapForm<>("form");
18 add(form);
19
20 treeProvider = new RecursiveDataTreeProvider(data);
21
22 DefaultNestedTree tree =
23 new DefaultNestedTree("dataTreeView"
24 , treeProvider)
25 {
26 private static final long serialVersionUID =
-7659715973883984412L;
27
28 @Override
29 protected Component newContentComponent(String id1
30 , IModel node)
31 {
32 return super.newContentComponent(id1, node);
33 }
34 };
35
36 form.add(tree);
37
38 BootstrapAjaxButton close = new BootstrapAjaxButton("close"
39 , Model.of("schließen"), Buttons.Type.Primary)
40 {
41 private static final long serialVersionUID =
7877084020329862442L;
42
43 @Override
44 protected void onSubmit(AjaxRequestTarget target, Form form)
45 {
46 super.onSubmit(target, form);
47 appendCloseDialogJavaScript(target);
48 }
49 };
50 form.add(close);
51 }
52
53 @Override
54 protected void onModelChanged()
55 {
56 super.onModelChanged();
57 String serviceId = getModel().getObject().getServiceId();
58 List newDataList =
dataBean.getRootDataByServiceId(serviceId);
59 treeProvider.setRecursiveData(newDataList);
60 }
61 }
I know from debugging that my implementation of ITreeProvider is
working well,
also after execution of "onModelChanged()".
But when the tree is rendered, this error occurs:
org.apache.wicket.WicketRuntimeException: Property could not be resolved for
class: class com.example.Service expression: dataTreeView

org.apache.wicket.core.util.lang.PropertyResolver.getGetAndSet(PropertyResolver.java:393)

at
org.apache.wicket.extensions.markup.html.repeater.tree.nested.Subtree.isVisible(Subtree.java:136)
Why does Wicket try to resolve a property that doesn't exist within "Service" ?
I've tried a version without a BootstrapForm within the Modal, where
"dataTreeView" is attached to the Modal directly. Same problem.

reusable Panel with Delete-Button and Confirmation Dialog (Bootstrap Modal), issue with page refresh
Hi,
I've created a reusable panel (DeleteObjectPanel.java) which contains a
BootstrapAjaxButton
for deleting database entries.
After clicking the button, a Bootstrap Modal (ConfirmDeleteModal.java) appears
for confirmation.
Both are in the package example.confirm.
MCVE is here:
https://gitlab.com/UlrichK/pageRefreshAfterConfirmation.gitStart of
application via test/java/example/Start.java
I need this because in my application I have some BootstrapDefaultDataTables
with deletion functionality.
The DeleteObjectPanel is used in Customer3.java line 131 , during creation of a
AbstractColumn.
After the deletion is performed, the datatable is refreshed.
But the hole page is disabled!!! See screenshot.
If a replace
target.add(filterForm);
with
target.add(filterForm, getPage());
the page gets refreshed, but I want to understand what is wrong in my code.
This is were I use DeleteObjectPanel (The DataTable is a child component of
filterForm"):
columns.add(
new AbstractColumn(new Model<>("Löschen"))
{
private static final long serialVersionUID = 1L;
@Override
public void populateItem(Item>
cellItem,
String componentId, IModel customerModel)
{
Customer customer = customerModel.getObject();
String customerInfo = "Kunde:\n"
+ customer.getName();
cellItem.add(new DeleteObjectPanel(componentId,
customerInfo)
{
private static final long serialVersionUID =
2408937138549967444L;
@Override
protected void performDeletion(AjaxRequestTarget
target)
{
//customerBean.deleteByUuid(customer.getBopUuid());
DatabaseLocator.getDatabase().delete(customerModel.getObject());
// Page is "disabled" completely
target.add(filterForm);
// THIS WORKS
//target.add(filterForm, getPage());
}
});
}
});
Mit freundlichen Grüßen

Re: Modal dialog, form validation in AjaxBootstrapTabbedPanel
Hi Martin, sorry for late replying. Issues in another project prevented me from testing your hint. Using ClientSideBootstrapTabbedPanel solved my problem completely. I simply replaced "class MyAjaxTabbedPanel extends AjaxBootstrapTabbedPanel" with "class MyAjaxTabbedPanel extends ClientSideBootstrapTabbedPanel " and removed unnecessary methods. Then, wicket gave me useful hints related to a ClassCastException and to a missing call to tabbedPanel.setOutputMarkupId(true) . Thank you for quick response.
