Hi Tobias,
I have followed your approach (update from parent) and it works. Thanks a

But could you show me also how to overwrite the visibility directly in the
ResourceLink?
ResourceLink pl = new ResourceLink(pdfLink, new
ByteArrayResource(application/pdf) {…}?
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.
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?
ListModelString listModel = new ListModelString() {
@Override
public ListString getObject() {
Thanks, Chris

In your snippet you put the isVisible in the ByteArrayResource. That's
why you get the error message - move it to your ResourceLink
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.
kind regards

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 IModelListA model) {
super(id, model);
ResourceLink pl = new ResourceLink(pdfLink, new
ByteArrayResource(application/pdf) {...}
pl.setVisible(routingModel.getObject().get(0).getElements().size() 0);
...
}

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
In your snippet you put the isVisible in the ByteArrayResource. That's why you
get the error message - move it to your ResourceLink
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,
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 ;
}
});

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
mentioning a lot about that topic:
https://wicket.apache.org/guide/guide/bestpractices.html#bestpractices_5
At this place it is good to mention the new location of the guide:
http://ci.apache.org/projects/wicket/guide/6.x/
http://ci.apache.org/projects/wicket/guide/7.x/
