Description Joseph Vincens

Create a program with the following
program Pgm1 type BasicProgram {}
		
	function main()
		rs1 SQLResultSet?;
		while (rs1.setNext())
		end
	end
	
end
An error will be shown on setNext().

I debugged into the problem and found the following.
in TypeBinding.getNullableInstance()
    nullableType = primGetNullableInstance();(line 134)

If the type is an external type:
ExternalTypeBinding.primGetNullableInstance() does
		ExternalTypeBinding nullable = new ExternalTypeBinding(this);

ExternalTypeBinding the constructor (ExternalTypeBinding(ExternalTypeBinding old)) does not copy the extendedTypes to the newly created object. It does     	List extendedTypes = old.extendedTypes; so the extendedTypes are copied to an unused variable.

Thanks for debugging this, it was indeed a copy/paste error. The "List" should have been removed, so that the variable declared in ExternalTypeBinding
