you dont need to put any code in your onsubmit...
class mysearchpage extends webpage {
private searchcriteria criteria=new searchcriteria();
public mysearchpage() {
add(new searchcriteriaform("form", new propertymodel(this,
"searchcriteria")));
^ form object connected to the criteria field of this page via a
property model
add(new listview("results", new propertymodel(this,
"searchresults")) {...});
^ listview that will display results retrieved from the
getSearchresults() method on this page
}
public list getSearchresults() {
// get whatever results based on the criteria field
}
}
so in short, form pushes your criteria into the criteria field,
listview uses the criteria field to build the resultset. yes, its that
simple :)
