Conditional Popup
Hello,
I have a wicket PopupPage that answers a wicket link, but I don't want it to
popup when certain conditions are not met. In that case I want an
info-message.
So I tried something like:
final Link<String> theLink = new Link<String>(...) {
public void onClick() {
if (condition) {
info("Do this first");
} else {
setPopupSettings(thePopupSettings);
setResponsePage(thePopupPage);
}
};
But no matter what I try, the popuppage always comes.

What about the AjaxLink alternative I already suggested?

Yes, this would be a possible solution, maybe something like that:
AjaxLink link = new AjaxLink("link") {
@Override
public void onClick(AjaxRequestTarget target) {
if (condition) {
info("...");
// target.add(feedbackPanel);
} else {
target.appendJavaScript("Wicket.$('" + myPopup.getMarkupId() + "').open();");
}
}
};
add(link);

You could also pass a model to the Page's constructor e.g.
Cheers,

But, how would you do that?
if (condition) {
info("Do this first");
} else {
activate JS-popup-opener ????
}
And furthermore, I need to pass data to the popup-page, so I would have to
stick that in the Session?

As an alternative, you could use an AjaxLink and push the popup-opener JS to teh frontend, then you could have your decision logic (wether to open it or not) in the backend (Wicket layer).

I thought you might have some condition that you could evaluate in JS. This is the reason I asked for a short quickstart, it simply eases discussion.

I'm sorry, but I don't understand your code. My condition is in the
Java/Wicket-layer, how can you put that between double quotes?

As I suppose that you want to create a Javascript popup (i.e. a Wicket Link with PopupSettings), you need to decide wether to open the popup or not in the frontend (Javascript layer), not in the onClick() of the Link. So you could try something like this:
PopupSettings popupSettings = new PopupSettings() {
@Override
public String getPopupJavaScript() {
return "if(!condition) return false; " + super.getPopupJavaScript();
}
};
Link link = new Link("link") {
@Override
public void onClick() {
// ...
}
};
link.setPopupSettings(popupSettings);
add(link);

This doesn't work. The condition has to be checked every time the link is
clicked, so within the onCLick().
setPopupSettings(null) gives the current page as popup.
Maybe this information is relevant: The link is part of a row in a repeater
(within the populateItem of a ListView).

try with:
if (condition) { setPopupSettings(nonNull) } else { setPopupSettings(null) }

For other questions I had earlier on, I created quickstarts, but, since I'm
working on a very complex application, I couldn't reproduce the problem in a
quickstart. I spent hours and hours copying more and more of my application
into the quickstart, but to no avail.
So again, it's a simple question: how to make a conditional popup.

To create a quickstart normally costs me around 5-7 seconds (copy/paste is my friend) ;-)
Isolating the problem is another question, right. But in your case this sound rather trivial. In my experience a lot of problems are solved easyly by creating a quickstart, in most cases because then I realize that I did something wrong ;-)

A quick-start costs me one or two hours; in the end, maybe I will. But I
think this is a reasonably simple question, so I'll await some
straightforward suggestions first.

Could you please provide a quickstart or post the interesting HTML and Java snippets?
