How do I add a field for a message attribute from another node to the Attribute Editor?

Suppose I have 3 nodes called GrandParent, Parent and Child. Child is connected to Parent and Parent is connected to GrandParent by Message attributes.

I would like to add a custom field in the Attribute Editor for GrandParent that refers to Child. Basically, a field for the message attribute of Parent receiving the connection to Child, but show that field in GrandParent.

It would look like what you get with editorTemplate -label "Brush Details" -addControl "child"; in AEParentTemplate.mel where child is the Message attribute for connecting a Child node. Message attribute

Except that I would like to add this to the Attribute Editor for GrandParent.

I managed to add other attributes from Parent to GrandParent by using editorTemplate -callCustom "parent_new" "parent_replace" in AEGrandParent.mel. In parent_new I create a dummy Parent node 

string $dummyParent = `createNode -skipSelect "Parent"`;

And I use it to add fields from Parent to the attribute editor of GrandParent. For example attrFieldSliderGrp -attribute ($dummyParent + ".numericValue") adds a field and slider for a float attribute called numericValue in Parent. I can do the same for a color attribute with attrColorSliderGrp -label $tmpStr -attribute ($dummyParent + ".color")

Then at the end of parent_new I delete the temporary node and I keep the values in the fields updated in parent_replace by updating the attribute reference for the fields (for example attrFieldSliderGrp -e -attribute "parentNode1.numericValue" "parentNumericValueField";).

My problem is that I can't find how to do the same for a Message attribute. I tried creating a attrFieldGrp with attrFieldGrp -attribute ($dummyParent + ".child"); but this crashes Maya 2014. I tried the same with attrControlGrp attrControlGrp -attribute ($dummyParent + ".child"); which gives an error that Message attributes are not supported by attrControlGrp.

Any idea how this can be achieved?

The solution was simply to use attrNavigationControlGrp to create the control. This control does not need the dummy Parent node and will create the UI for node connections.
