Why not if you have the page call:
page.getExpression()
Then it is compile time save it refactores nicely
In my eyes the the PropertyModel is just handy and there is no otherway to do it then by using strings.
It is a pitty that we can give method or field pointers like:
new PropertyModel(user, User.class.name)
where name is then the field itself that is compile time and refactor save.
I don't see the big plus why you would script everywhere. You could make it yourself if you want
pretty easy just subclass a page and make that performAction method.

Didn't know that was a bad thing...

We can already do this:
PropertyResolver.getValue("_expression_", this.getPage());
I'd like to just be able to type:
this.getValue("_expression_");
or
this.getPage().getValue("_expression_");
...or, something like that.
Did you look at the NSKeyValueCoding docs?
