I've a diagram with lots of labels, and many of the labels are objects
that are defined in the model as EDataTypes. In the corresponding
factory implementation I have defined convertXXXToString and
createXXXFromString for handling string conversion, and this is
automatically used by the property sheet, when presenting and editing
values. The label editors do not use these, however. Instead they use
MessageFormat and toString, for EDataType values.
To fix this, I redefined the getValidValue (and getValidNewValue), so
that it converts the value using the appropriate factory method
(i.e. in getValidValue insert value =
type.getEPackage().getEFactoryInstance().convertToString((ED ataType)type,
value); and in getValidNewValue insert
value =
type.getEPackage().getEFactoryInstance().createFromString((E DataType)type,
(String)value);)
giving the same behavior as the property sheet. I can understand that
this is not always the desired behavior, but I suggest that this is a
reasonable default behavior that should be standard for GMF.
Have I missed something? Comments?

Guess, it's an overlook and would be great if you file a bugzilla.
Thanks
