how to fix null pointer issue

[scape2code 0]

    I want to it to sleep until the widget is visibile but I get a null pointer exception until that actually happens but its only going to be null or only supposed to be null until I interact with the 2 objects what do I do to fix this or does it not matter. It seems like my program may skip a sleep statement which throws everything off.  Code below is basically just me debugging problem

	if(getWidgets().getWidgetChild(270,14,38) == null)
		{
			log("widget child isnot visible yet");
			sleepUntil(()->getWidgets().getWidgetChild(270,14,38).isVisible(),10000);
			log("widget child is  visible son");
		}

You enter that if statement when the widget is equal to null, so you are getting a null pointer exception when you do 

sleepUntil(()->getWidgets().getWidgetChild(270,14,38).isVisible(),10000);

because you are trying to do that on a null widget. Instead maybe you could try something like

sleepUntil(()->getWidgets().getWidgetChild(270,14,38) != null,10000);
