Can Initial-Value be a Constant?

I hava a class: 

public abstract class foo extends BasePage {
  public static final int MOJO = 0;
  public static final int MOREMOJO = 10;

}

And I would like to create a foo.page with a property
in the foo.page:

<property-specification name="howMuchMojo" type="int" initial-value="foo.MOJO" persistent="no"/>

This does not work, I recieve an error:
Unable to initialize property howMuchMojo of com.bobnet.stuff.foo$Enhance_67@9486a5[]: 
Unable to read expression '<parsed expression>' of com.bobnet.stuff.foo$Enhance_67@9486a5[].
I have tried the following initial-value combinations:
MOJO
foo.MOJO
com.bobnet.stuff.foo.MOJO
Is it even possible to initialize a property with a constant?
Any Suggestions?
Filip

Try this syntax:

   <property-specification ...  initial-value="@foo@MOJO" ... />
