How to change BookmarkablePageLink Model?

[Major Péter <ma...@sch.bme.hu>]

Hi all,

In my project, i would like to change the link for an image in different 
pages, where the image is in the header (which is in the base class of 
pages).
The code snippet i tried:

//This is my base class for the other pages
public class PageTemplate extends WebPage {

...
//The base class constructor
public PageTemplate(){
WebMarkupContainer headerLabelContainer = new 
WebMarkupContainer("headerLabelContainer");
        add(headerLabelContainer);
//I have to set a default value, so it would be declared for wicket, so 
when i have a page, which i don't want to contain this imagelink, there 
won't be a problem
        headerLabelContainer.add(new BookmarkablePageLink("detailView", 
ShowUser.class)).setVisible(false);
                                    }
...

public void setHeaderDetailViewLink(Class pageClass, String param) {
        get("headerLabelContainer").setVisible(true);
//this part is what won't work:
            ((WebMarkupContainer) 
get("headerLabelContainer")).get("detailView").setModel(new 
Model(UserHistory.class));
                // i tried also new bookmarkablepagelink(...), but the 
problem is the same, the link is pointing to the pre-declared page...
...
}

The HTML code is:

<div class="header" wicket:id="headerLabelContainer">
<a wicket:id="detailView" class="btn"><img 
src="images/btnDetailView.gif" alt="Részletes nézet" /></a>
                </div>

So the simple question would be: how to change the bookmarkablepagelink 
model?
The header also has a Label, which changes by pages, with the 
setModel(new Model("new text")); command...
I can't figure out what the problem is.

Regards,
Peter Major

Peter,

Create a Panel or Fragment that takes the page you want to link to in its
constructor (or returns it in an abstract getPageToLinkTo() method). This
will contain your BPL (you can still embed your static img tag in the
associated html) and you can set the whole Panel/Fragment to be invisible by
default (or just do it in your template page) and let subclasses
override/set the visibility as required.
