Nifty.createPopup hath defeated me

Troubleshooting gui

Everything is null. What do you get when you call the create popup function? Null. All the time. I have yet to call that function and not get a nullpointerexception.

Here is the xml and relevant java code:

[java] public void initializePopups(){
//<editor-fold desc=“Win By Destruction” defaultstate=“collapsed”>
if(nifty!=null){
winByDestruction = nifty.createPopup(“popup”);
Menu wbdMenu = winByDestruction.findNiftyControl("#menu", Menu.class);
wbdMenu.setWidth(new SizeValue(“100px”)); // must be set
wbdMenu.addMenuItem(“The world has suffered over 5,000,000$ in losses over your malware.”, “You have won.”);
wbdMenu.setId(“wbdMenu”);
}
//</editor-fold>
}[/java]

I have absolutely no useful input to this thread… I just wanted to say the the topic title made me laugh; :wink: Very stoic!

Somebody needs to learn to be a little patient. It hasn’t even been a day :). That being said… createpopup fails because you haven’t defined a popup correctly. You need to define them at the same level as the screen nodes. Popups are meant to be reusable components that could be called from any screen. I would also name it something other than “popup” since there could be a naming conflict there.

That solved the first issue, but Menu is now null. Any hints?

I believe that when you put “#” in front of an ID it actually ends up being {parent id}#menu and not #menu but I could be wrong. Either way, you are trying to retrieve an ID of an element that it can’t find which is why it is null.
