Java - getAttribute - always null?

[gubaer]

Hi,

I have a MegaObject  obj from which I can retrieve a property, but not the corresponding attribute

obj.getProp("~Fxk9BUYZI1GA[Fachliche Beschreibung]");  // OK  - works

obj.getAttribute("~Fxk9BUYZI1GA[Fachliche Beschreibung]");  //  => null
obj.getAttribute("~Fxk9BUYZI1GA");                          //  => null
obj.getAttribute("Fachliche Beschreibung");                 //  => null

Any idea/hint how to retrieve the attribute?

Regards

Karl
