Problem with calls methods

[jzafrilla.tecnico.antswayofworking.es]

Hi all,
I have a search form, which uses hibernate-search. I created a component called SearchManager, which gets the list of terms found. My problem is that when i press the search button, repeating the call many times!
I have just one call to getResultList () in my DataTable. Why is executed several times the call? How can I fix this?

Thx.

Datatable value attribute may be evaluated several times. Use lazy initialization :

class SearchManager {

    List results;

    public List getResultList() {
        if( results == null ) {
             results = realGetResults();
        }
        return results;
    }
}

Or use @DataModel.
