Is there a way to use a property of the type %Persistent class in a  %ZEN.Component.page class?
Example:

// Data classClassExtends

Class

The problem is that when using it the described in the example.
The property can be set in a Method like this:

Method DoStuff() 

But when reading the property in an other Method the content of it is not set:

Is it generally possible to work like this?
Or have I overlooked a special handling?
