popup problem

2008-01-09 Thread palun 

Hi all,

I am trying to open a popup window from a page. Code looks like so:

PopupSettings popupSettings = new PopupSettings(PageMap
.forName(popuppagemap)).setHeight(300).setWidth(200);
PageParameters params = new PageParameters();
params.add(header, Answer);
params.add(text, [answer is shown here]);
item.add(new BookmarkablePageLink(popupButtonLink,
MyPopupPage.class, params).setPopupSettings(popupSettings));

The constructor of my popup window looks like:

public MyPopupPage() {
add(new Label(header,(String) getPageParameters().get(header)));
add(new Label(text,(String) getPageParameters().get(text)));
  add(new PopupCloseLink(return));
}

When I run it, the popup window pops up alright, but it displays a
NullPointerException. Apparently getPageParameters() returns null. Anyone
knows why?

(Sorry if this is elementary wicket stuff. I'm a beginner.)

Thanks
/ulf

That would be the first line in the constructor:

public MyPopupPage(PageParameters params) {
add(new Label(header, (String) params.get(header)));   --- 
line 12
add(new Label(text, (String) params.get(text)));
add(new PopupCloseLink(return));
}
