Re: binding problem :(
Actually when I do the form.getModelObject() the debugger shows that it added a
nestedModel.
Model:classname=[org.apache.wicket.model.CompoundPropertyModel]:nestedModel=[[false,
false]]

binding problem :(
Hi All,
For some reason, my checkbox doesn't bind to my model. I have a
DataView that contains the Check component, and in my button, onClick, I use
form.getModelObject(), but the objects doesn't get set. (Earlier than this, I
tried AjaxButton and the form.getModelObject() returns an array of boolean)
Is there something missing? Here's the scenario:
CompoundPropertyModel compoundPropertyModel = new
CompoundPropertyModel(detachableModel);
final Form myform = new Form(formId,compoundPropertyModel);
CheckGroup checkGroup = new
CheckGroup(checkGroup,compoundPropertyModel);
checkGroup.add(new CheckGroupSelector(groupSelector));
SortableDataProvider dp = new SortableContactDataProvider();
DataView dataView = new DataView(contacts,dp) {
...
protected void populateItem(Item item) {
Contact contact = (Contact) item.getModelObject();
item.setModel(new CompoundPropertyModel(contact));
item.add(new Check(selected) );
}
};
checkGroup.add(dataView);
myForm.add(checkGroup);
IndicatingAjaxLink link = IndicatingAjaxLink(link) {
@SuppressWarnings(unchecked)
@Override
public void onClick(AjaxRequestTarget target) {
CollectionContact contactList =
(CollectionContact) form.getModelObject();
if(contactList != null !contactList.isEmpty()) {
for(ContactWrapper contactWrapper: contactList)
{
System.out.println(contact selected: +
contactList.isSelected() );
}
}
}'
myForm.add(link);
Thanks for the help! Any suggestions/comments will be greatly appreciated!
Best,
Wen Tong

Re: binding problem :(
Hi Timo,
Thanks for the insight. I have to use CheckGroup, because i have to provide a
check all/uncheck all checkbox. I got a typo there, the isSelected() is
supposed to be part of Contact. And you're right, the isEmpty() is redundant if
I use the for-each type loop. That's a remnant of the old code I tried earlier.
I changed the AjaxLink to AjaxButton, and when I inspect the form in my
debugger, it holds the model, and a list of boolean.
Thanks,
Wen Tong

Re: binding problem :(
I think for some reason, when I submit, it overrides the model in the form. and
when I do form.getModelObject() it returns a wrong value. I'm suspecting that
its in the bind part of my populateItem(). I don't know why though.
