directlink and updating page

Hello
I'm trying to do a directlinkt with it's listener,
which get's (1) data from the visit-object and stores
(2) it back to it. This would be necessairy to update
the page.
Please follow my code:

.Page:
<component id="nextList" type="DirectLink">
  <binding name="listener"
expression="listeners.nextListLink"/>
</component>   

.java:
/**nextListLink: show next list of results.*/
public void nextListLink(IRequestCycle cycle){
  Visit visit = (Visit)getVisit();        
  int sum =
visit.getTelSearchContainer().getIndex()+RESULTNUMBERS;
     //(1)
  visit.getTelSearchContainer().setIndex(sum);				
//(2)
  ...
  SearchResult searchResult = new SearchResult();
    try {
      searchResult = sf.getMatchingAddresses(address,
sum, searchResult, false, false);
     
visit.getTelSearchContainer().setSearchResult(searchResult);
 //(2)
    } catch (Exception e) {
      log.error(e.getMessage());
    }
    ...

By debugging It seem's that it wont update the visit
in (2)?

Any idea?

Mirko

I don't see what the problem is with #2, but if you're not sending a
parameter with DirectLink, why not use ActionLink instead?

Are you catching an error in your try/catch block?
