objectName depends on non-NOTIFYable properties

When running the below example I get "QDeclarativeExpression: Expression "(function $text()

{ return parent.objectName }

)" depends on non-NOTIFYable properties:
QDeclarativeRectangle::objectName"

warnings on the output.

It might be an idea to either add a objectNameChanged signal to QObject or to suppress the warning inside Qt.

I use the objectName to create tooltips for indentification purposes during development.

import Qt 4.7

Rectangle {
height : 200
width : 200
color : "lightsteelblue"
objectName : "someRectangle"
Text

{ anchors.centerIn : parent height : 30 text : parent.objectName }

}
