Re: update visibility of resourcelink
Yes thats the right way - LDM saves the model object for the whole request!
(Load method is invoked once per request) - good!

Re: update visibility of resourcelink
hi, thanks a lot.
I have done it with a LDM and overriding the isVisible and onDetach method:
model = new LoadableDetachableModel>() {
@Override
protected List load() {
List locationsNotInRoute = Lists.newArrayList();
List locationsInRoute = Lists.newArrayList();
for (Route route : routingModel.getObject()) {
for (Location location : route.getLocations()) {
locationsInRoute.add(location.getOntologicalName());
}
}
for (Poi poi : user.getSelectedPois()) {
if (!locationsInRoute.contains(poi.getOntologyLocalName()))
{
locationsNotInRoute.add(poi.getName());
}
}
return locationsNotInRoute;
}
};
ListView locationsNotInRoutesView = new
ListView("locationsNotInRoutes", model) {
@Override
protected void populateItem(ListItem
listItem) {
listItem.add(new Label("locationNotInRoute",
listItem.getModel()));
listItem.setOutputMarkupId(true);
}
@Override
public boolean isVisible() {
return calculationDone &&
model.getObject().size() > 0;
}
};
@Override
public void onDetach() {
if(model != null)
model.detach();
super.onDetach();
}

Hi,
thanks, I am getting the message "method does not override method from its

The problem is that I do not have the callback method in this panel but in
its parent; I would need to have a getter method so that I can directly
access the resource link from the panel instance and change its visibility.
ResourceLink pl = new ResourceLink("pdfLink", new
ByteArrayResource("application/pdf") {
@Override
protected boolean isVisible() {
return ;
}
});

Re: update visibility of resourcelink
Hi,
have a look at models in the user guide there are some good approaches to
update them.
Visibility:
ResourceLink pl = new ResourceLink("pdfLink", new
ByteArrayResource("application/pdf")) {
// visibility method
}

Move "ByteArrayResource bar = new ByteArrayResource() {...}" a line above,
as a separate statement. Then override ResourceLink's #isVisible() method.
This way you'll notice your error in the old version.

Re: update visibility of resourcelink
Hi Tobias,
I have followed your approach (update from parent) and it works. Thanks a lot.
But could you show me also how to overwrite the visibility directly in the
ResourceLink?
ResourceLink pl = new ResourceLink("pdfLink", new
ByteArrayResource("application/pdf") {…}?
By the way, in the panel I have added another list view which does not use the
model of the panel but has to calculate the model dynamically.
With the following code, it seems also to be only called once in the
constructor but not via ajaxUpdate. How to change this?
ListModel listModel = new ListModel() {
@Override
public List getObject() {

One easy way to update from parent would be: make a method in your panel which
returns your link then make your panel a field in the parent and call the
getter in the callback and add the link to your AjaxRequestTarget there.

Hi,
the constructor of your panel is only called at a normal request - you
have to set the visibility of your link in the ajax callback via
AjaxRequestTarget.
1. setOutputMarkupId and setOutputMarkupPlaceholder of the link to true
(in your constructor)
2. set the visibility to your component in the callback method (based on
your Model)
3. add the component to the AjaxRequestTarget so that it is updated
Another solution would be to override the isVisible method and return the
visibility based on your model and then only add the component to the
AjaxRequestTarget.

Re: update visibility of resourcelink
Hi,
thanks, I am getting the message "method does not override method from its
superclass."
The problem is that I do not have the callback method in this panel but in its
parent; I would need to have a getter method so that I can directly access the
resource link from the panel instance and change its visibility.
ResourceLink pl = new ResourceLink("pdfLink", new
ByteArrayResource("application/pdf") {
@Override
protected boolean isVisible() {
return ;
}
});

Hi all,
currently, the visibility of the resource link is not updated when the

How can the visibility set dynamically based on the model’s data?

Re: update visibility of resourcelink
Yes - should work because isVisible is inherited from component:
http://ci.apache.org/projects/wicket/apidocs/6.0.x/org/apache/wicket/markup/html/link/ResourceLink.html
But watch out not to put in expensive calls in it! The user guide is also

Re: update visibility of resourcelink
Hi Tobias,
thanks! Can the isVisible method be directly overridden also by a
ResourceLink?
ResourceLink pl = new ResourceLink(..) {
protected boolean isVisible() {…}
}

Re: update visibility of resourcelink
Hi,
the constructor of your panel is only called at a normal request - you have to
set the visibility of your link in the ajax callback via AjaxRequestTarget.
1. setOutputMarkupId and setOutputMarkupPlaceholder of the link to true (in
your constructor)
2. set the visibility to your component in the callback method (based on your
Model)
3. add the component to the AjaxRequestTarget so that it is updated
Another solution would be to override the isVisible method and return the
visibility based on your model and then only add the component to the
AjaxRequestTarget.
kind regards

update visibility of resourcelink
Hi all,
currently, the visibility of the resource link is not updated when the parent
component of the panel is rendered again based on an ajax call.
How can the visibility set dynamically based on the model’s data?
Thanks, Chris
public SomePanel(String id, final IModel> model) {
super(id, model);
ResourceLink pl = new ResourceLink("pdfLink", new
ByteArrayResource("application/pdf") {...}
pl.setVisible(routingModel.getObject().get(0).getElements().size() > 0);
...
}
