Sorry I'm not sure I follow.
What I'm trying is to add a new PageParameter to the set that the
current page is created with. So I get the Page, get it's pageParameters
and add a new one to the existing set and feed that to the
bookmarkablepagelink.
If I would do:
protected void populateItem(ListItem item) {
PageParameters p = new PageParameters();
String key = (String)item.getModelObject();
p.add("key", key);
BookmarkablePageLink lnk = new BookmarkablePageLink("link", HomePage.class, p);
item.add(lnk);
}
the bookmarkablepagelink would only contain the new pageparameter, not
the already existing pageparameters
What happens now is that getPage().getPageParameters is not returning
the PageParameters from the current page, but is returning the
pageparameters I just added to the bookmarkablepagelink + the ones that
are already in getPage().getPageParameters.
So if you take the example below, and say I have clicked on the first
link. The output of HTML would then look like:
<li wicket:id="test">
<a href="?key=aaa&key=aaa" wicket:id="link">test</a>
</li>
<li wicket:id="test">
<a href="?key=aaa&key=aaa&key=bbb" wicket:id="link">test</a>
</li>
<li wicket:id="test">
<a href="?key=aaa&key=aaa&key=bbb&key=ccc"
wicket:id="link">test</a>
</li>
<li wicket:id="test">
<a href="?key=aaa&key=aaa&key=bbb&key=ccc&key=ddd"
wicket:id="link">test</a>
</li>
While I expect:
<li wicket:id="test">
<a href="?key=aaa&key=aaa" wicket:id="link">test</a>
</li>
<li wicket:id="test">
<a href="?key=aaa&key=bbb" wicket:id="link">test</a>
</li>
<li wicket:id="test">
<a href="?key=aaa&key=ccc" wicket:id="link">test</a>
</li>
<li wicket:id="test">
<a href="?key=aaa&key=ddd" wicket:id="link">test</a>
</li>

So why don't you expect the loop to add them to the existing parameters?

because I want to use the already existing parameters and add them to

Why don't you create a new PageParameters object in each populateItem?
