i suggest you read here:
http://cwiki.apache.org/confluence/display/WICKET/Working+with+Wicket+models
the idea is pretty simple:
the form submits its data into a bean, and the view renders according to
that bean. this is accomplished by having the form and the view's models
connected to the same bean via models.

hi igor,
i'm trying to implement your advice, but don't really know
how to do this.
what would the SearchForm then look like? does the form itself
use the model and how is the input field added to the form?
and how can the ResultsView access the value of the PropertyModel?
the model has a getObject(Component) accessor - does this mean that
the ResultsView would need pass the SearchPage into getObject?
thanx && cheers,
martin
