[4.0] @Persist initial-value workaround

["Ido M. Tamir" <ta...@imp.univie.ac.at>]

Hi,

@Persist
"This annotation works exactly like a <property> element, except that the 
initial-value attribute can't be specified."

is this left out on purpose?
How can I currently create a property or parameter and connect it to a 
component as in:

 // @Persist or
 @Parameter( defaultValue="new Distance()" )
 public abstract Distance getDistance();

 @Component( type = "TextField", bindings = {
 "value=Distance.distance",
 "displayName=selectSpan",
 "translator=number,pattern=#",
 "validators=required,min=1,max=20000"
     })
    public abstract TextField getSpan();

with Distance something like:

public class Distance {
 public Long getDistance();
 public void setDistance(Long dist);
}

Defining a parameter with defaultValue makes it
available, but it doesn't get changed upon
editing.
And as a property without initial-value it is of 
course null.

Thank you very much for your 
answer
Ido
