Create a Handler with the following content:

handler H4 type RUIhandler{initialUI =[var1_ui
            ], onConstructionFunction = start, cssFile = "css/P1.css", title = "H4"}

    var1 Rec1;
	
	var1_ui GridLayout { rows = 1, columns = 2, cellPadding = 4, children = [ var1_item1_nameLabel,var1_item1_field ] };

	var1_item1_nameLabel TextLabel { text="item1" , layoutData = new GridLayoutData { row = 1, column = 1} };
	var1_item1_field DojoTextField { readOnly = true , layoutData = new GridLayoutData { row = 1, column = 2} };
	var1_item1_controller Controller { @MVC {model = var1.item1, view = var1_item1_field} };
	
    function start()
    end
end

Record Rec1
	item1 String {@InputRequired};
end

If you run an incremental build, it will compile cleanly.  If you run a clean build, you will get the following NPE:

	at org.eclipse.edt.gen.javascript.annotation.templates.MVCTemplate.preGen(MVCTemplate.java:109)

After looking at the code, it looks like the MVCTemplate is throwing an NPE because the IR has no default value for the annotation during a clean build, but it has a default value of 'YES' during an incremental build.
