Hi I want to generate a poopup in hud screen but when I try to instantiate the popup defined in xml it generates a exception.
[java] de.lessvoid.nifty.elements.Element popupElement = nifty.createPopup(“popupConfirm”);
nifty.showPopup(nifty.getScreen(“hudScreen”), popupElement.getId(), null);
[/java]
XML - last part, it renders with no error and works perfectly
[java]
<popup id=“popupConfirm” childLayout=“center” backgroundColor="#000a">
<panel id=“pane” height=“25%” width=“75%” align=“center” childLayout=“center” backgroundColor="#BD2424ff">
<text text=“Welcome to Aspiring Minds” color="#000" font=“Interface/Fonts/Default.fnt” width=“100%” height=“100%” />
</panel>
</popup>
</screen>
</nifty>[/java]
