Form with backing loadabledetachable model
Hello,
I have a list of items in a Refreshing View.
When I click on a link inside the Refreshing View, a form in the same page
should get populated with the values from the line.
I have managed to do this, by having inside the Form a
LoadableDetacheableModel and then use this model as backing model for the
components in the form.
However, I have also a drop down inside the form, but when changing the
value, the LoadableDetacheableModel does not get updated with the new
value.
Or if using getModelObject(), all values are null, because, the backing
model of the form is null.
Could you please advise?
Thank you

Hi,
you should brush up your model usage:
final MyBean tst = poItemsListModel.getObject();
Your pulling the model object from the model *once* only. The reference
'tst' never gets updated, when the model changes.
I've attached an alternative solution below. I'd recommend not changing
models after components are constructed. It's much easier to change
model objects only.
Have fun

Re: Form with backing loadabledetachable model
Posted by ganea iulia <su...@gmail.com>.
Hello,
=Here is the RefreshingView link item. When clicking on this link, the form
should be filled with the values of this RefreshingView line.
When click on the link, I set the property itemmodel with the line model.
The itemmodel is then used by the LoadableDetacheableModel, to get the
values for the form.
// edit link
AjaxLink<MyBean> linkEditItem = new AjaxLink<MyBean>("linkEditForm", model)
{
private static final long serialVersionUID = 15L;
@Override
public void onClick(AjaxRequestTarget target) {
feedbackPanel.getFeedbackMessages().clear();
editForm.clearInput();
editForm.setItemmodel(new Model<MyBean>(item.getModelObject()));
target.add(editForm);
target.add(feedbackPanel);
}
};
=Here is the form:
class EditForm extends Form<MyBean> {
/**
* Form where you can edit the items from the list
*/
private static final long serialVersionUID = 1L;
private IModel<MyBean> itemmodel;
public void setItemmodel(IModel<MyBean> itemmodel) {
this.itemmodel = itemmodel;
}
public EditForm(String id, IModel<MyBean> model) {
super(id, model);
this.itemmodel = model;
final LoadableDetachableModel<MyBean> poItemsListModel = new
LoadableDetachableModel<MyBean>() {
private static final long serialVersionUID = 0L;
@Override
protected MyBean load() {
return itemmodel.getObject();
}
};
// Edit ITEMS
final WebMarkupContainer editContainer = new
WebMarkupContainer("editContainer");
editContainer.setOutputMarkupId(true);
add(editContainer);
final MyBean tst = poItemsListModel.getObject();
// unrepairable
DropDownChoice<String> unrepairable = new
DropDownChoice<String>("unrepairable", lstSN, renderer) {
private static final long serialVersionUID = 1L;
*@Override*
* public boolean isEnabled() {*
* return (tst.getId() == null || (tst.getIrreparableSal() != null &&
!tst.getIrreparableSal().equals("S")));*
* }*
};
unrepairable.setModel(new PropertyModel<String>(poItemsListModel,
"irreparableSal"));
unrepairable.setOutputMarkupId(true);
editContainer.add(unrepairable);
unrepairable.add(new AjaxFormComponentUpdatingBehavior("change") {
private static final long serialVersionUID = 1L;
@Override
protected void onUpdate(AjaxRequestTarget target) {
target.add(unrepairable);
}
});
In this piece of code(also in bold above), I cannot ever get the actual
values of my LoadableDetacheableModel; they are always null, they never get
updated with the values of the line.
*@Override*
*public boolean isEnabled() {*
* return (tst.getId() == null || (tst.getIrreparableSal() != null &&
!tst.getIrreparableSal().equals("S")));*
*}*

how does your LDM load its model object?
Show us some code or better create a quickstart so someone can take a
look at it.
