I m using lazy loading with pagination in a dataTable, and works fine. The problem is that I have an advanced search functionality in the same html page, and when I click on the search button, I want my dataTable to be updated according to the values I entered in the advanced search fields (this functionality is implemented at DaoFactory.getDocumentoDao().buscarLazy(first, pageSize), the code is below. But the update attribute at my button doesn t seem to do anything becouse the load method of the lazy model is not called. So the question is: can I somehow call the load method of the lazy model from outside of the model in order to have my dataTable updated?

表格M:

<h:form id="frmCli">
    <p:commandButton value="Buscar"
                     update="frmCli:panelResultadosDoc"/>
    <h:panelGroup id="panelResultadosDoc">
        <div class="dataTable">     
            <p:dataTable id="documentos"
                         value="#{documentoBuscadorBean.lazyModel}"
                         lazy="true"
                         var="varDocBean"
                         paginator="true"
                         paginatorPosition="bottom"
                         paginatorAlwaysVisible="false"
                         rows="5">           
                <p:column>
                   <f:facet name="header">Código</f:facet>
                   <h:outputText value="#{varDocBean.documento.id}"/>
                 </p:column>                                                         
            </p:dataTable>
        </div>     
    </h:panelGroup>
</h:form>

有待于:

@ManagedBean
@SessionScoped
public class DocumentoBuscadorBean {

   private LazyDataModel<DocumentoBean> lazyModel;

   @SuppressWarnings("serial")
   public DocumentoBuscadorBean() {

      lazyModel = new LazyDataModel<DocumentoBean>() {

      public List<DocumentoBean> load(int first, int pageSize, String sortField, boolean sortOrder, Map<String,String> filters) { 
            List<DocumentoBean> lazyListDocumentos = new ArrayList<DocumentoBean>();
               try {                  
                  lazyListDocumentos = DaoFactory.getDocumentoDao().buscarLazy(first, pageSize);
             } catch (DocumentoException e) {
                e.printStackTrace();
             }
               return lazyListDocumentos;
           }         
         };            
         lazyModel.setRowCount(DaoFactory.getDocumentoDao().rowCount());
         lazyModel.setPageSize(5);
   }
   public LazyDataModel<DocumentoBean> getLazyModel() {
      return lazyModel;
   }

}
