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.

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
images/btnDetailView.gif
/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
