Hi
I'm new to richfaces.
I've got page with three forms, in third I got a repeater with button for every row. Button click deletes value and makes rerender, but nothing heppends.

Code of form:

<a4j:form id="form2">
 <a4j:outputPanel id="abonamentListOutputPanel">
 <t:div id="abonamentListDiv" rendered="#{personEditBean.deletable}"
 styleClass="insideBox_2">
 <br />
 <h:outputText value="Wykupione Abonament" />
 <br />
 <table>
 <tr>
 <td>Nazwa</td>
 <td>Data od</td>
 <td>Data do</td>
 <td>Akcja</td>
 </tr>
 <a4j:repeat id="purchasedAbonamentsRepeater"
 value="#{personEditBean.person.purchasedAbonaments}"
 var="listObj">
 <tr>
 <td><h:outputText value="#{listObj.abonament.name}" /></td>
 <td><h:outputText value="#{listObj.dateFrom}" /></td>
 <td><h:outputText value="#{listObj.dateTo}" /></td>
 <td><a4j:commandButton
 id="deletePurchasedAbonament_"
 action="#{personEditBean.deletePurchasedAbonament}"
 value="Delete" reRender="abonamentListOutputPanel"
 >
 <f:param name="purchasedAbonament_id" value="#{listObj.id}" />
 </a4j:commandButton></td>
 </tr>
 </a4j:repeat>
 </table>
 </t:div>
 </a4j:outputPanel>
 </a4j:form>

Hibernate logs shows something interesting - first select for repeater begins, after that hibernate deletes.

Method code:

public void deletePurchasedAbonament() {
 String purchasedAbonament_id = FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap()
 .get("purchasedAbonament_id");

 Long abonamentToDelId = Long.valueOf(purchasedAbonament_id);
 Session session = HibernateUtil.getSessionFactory().getCurrentSession();
 session.beginTransaction();
 PurchasedAbonament tempPA = (PurchasedAbonament) session.load(PurchasedAbonament.class, abonamentToDelId);
 session.delete(tempPA);
 session.getTransaction().commit();

 }

Any idea whats wrong ?
