Bug 358194

Description Huang Ji Yong 2011-09-20 04:10:29 EDT

Build Version: 201109192102

Create a RUIHandler contains the following code will have compile error and generates the below errors. The problem is in this statement if(myDelegate==null): delegate cannot compare with null(equal or not equal).
Null is parsed as StructPart type, is this the problem?

-- TestCase --
Delegate myDelegate() end
handler testNull type RUIhandler{initialUI =[ ], onConstructionFunction = start, cssFile = "css/testIR.css", title = "testNull"}

	myDelegate MyDelegate?;
    function start()
    	if(myDelegate==null)
    		syslib.writeStdout("compare to null");
    	end
    end
end
-- Errors --
