I got that to work, it's great, I hadn't notice all the values can have a prefix to change the scope.
The problem is that the method that returns the option values and sets the blankOption value is invoked after the blankOption getter. This is a problem I have hit before where a property value depends on the result of a property value that is invoked later. I don't really want to store results in the session and am wondering if I should use a cache instead. Is there any recomended approach in Tapestry? Maybe I should use ehCache? My typical example is a property that returns a collection from a DAO to iterate over for a table or select list, and then some other property whos state depends on that result in some way. So far I have been using intermediate helper beans to bind the related state data.
