Test EGL Files.

Create a package named pack2 and import the attached .egl files into the package.

When the files are generated, the following exception is thrown:

Caused by: org.eclipse.edt.mof.egl.AmbiguousFunctionReferenceError
	at org.eclipse.edt.mof.egl.impl.QualifiedFunctionInvocationImpl.resolveFunction(QualifiedFunctionInvocationImpl.java:116)
	at org.eclipse.edt.mof.egl.impl.QualifiedFunctionInvocationImpl.getTarget(QualifiedFunctionInvocationImpl.java:49)
	... 89 more

It looks like we need to add the following code to the end of TypeUtils::getBestFitFunctionMember - 

if (result.isEmpty()){
			result = candidates;
		}

		// If we still have more than one result, check to see if the first item in the list is in a part that is a subtype of the second part in the list
		// If the first part in the list is a subtype of the second part in the list, just return the first part in the list
		if (result.size() > 1){
			// Check to see if first function in the list is located in a subtype of the second function
			T first = (T)result.get(0);
			T second = (T)result.get(1);
			
			if(isSubtypeOf(((StructPart)first.getContainer()).getClassifier(), (EGLClass)IRUtils.getEGLType(((StructPart)second.getContainer()).getTypeSignature()))){
				result.clear();
				result.add((T) first);
			}
		}
		return result;

It is also worth noting that Container.getAllMembers seems to return a different set of functions when External Types are being used directly, as compared to RUIWidgets, which extend from Widget.  The attached .egl files contain an example of this scenario.
