Hmm - I'm absolutely sure its defined nowhere else in my (rather huge)
application.
But my usecase is a little different:
qs:
var child = Form.findChild ("child1");
var children = child.findObjects ("MyClass");
and only in 4.6 code I need to set:
Q_DECLARE_METATYPE (QObjectList);
qScriptRegisterSequenceMetaType <QObjectList> (scriptEngine);
Maybe it has sth. to do with usage of findObjects (QString) ???
At least thats where the error is thrown when qs is executed.
