good day.
i tried to use modal panel for editing datatable.
i have some input fields into the modal panel and fill them by onshow javascript event, after changes i have a4j:commandButton and trying to save changed fields, but i can't get values into backing bean. my code snippets :


1. view.xhtml (containing modal panel)

<h:form id="pageForm">
 ......... (datatable view and so on..)
</h:form>
<h:form id="modalForm">
 <a4j:region id="modalRegionId">
 <modPanel:modalPanel id="mp" moveable="true" height="115" width="310" zindex="2000"
 onshow="document.getElementById('modalForm:prpNameModal').value=event.parameters.propName;
 document.getElementById('modalForm:prpIdModal').value=event.parameters.propId;">

 <f:facet name="header">
 <h:outputText value="Edit Properties" />
 </f:facet>
 <f:facet name="controls">
 <h:graphicImage value="/img/close.png" style="cursor:pointer" onclick="Richfaces.hideModalPanel('mp')" />
 </f:facet>
 <table border="0" cellpadding="0" cellspacing="0" width="100%">
 <tr>
 <td>
 <h:outputLabel for="prpIdModal">Property Id</h:outputLabel>
 </td>
 <td>
 <h:inputText id="prpIdModal" disabled="true" styleClass="inputfield" style="width:100%"/>
 </td>
 </tr>
 <tr><td style="height:5px;"></td></tr>
 <tr>
 <td>
 <h:outputLabel for="prpNameModal">Property Title</h:outputLabel>
 </td>
 <td>
 <h:inputText id="prpNameModal" value="#{property.propertyName}" styleClass="inputfield" style="width:100%"/>
 </td>
 </tr>
 <tr><td style="height:12px;"></td></tr>
 <tr>
 <td align="right" colspan="2">
 <a4j:status id="submitStatusId" for="modalRegionId" startText="Saving ... " stopText="">
 </a4j:status>


 <a4j:commandButton id="submitAdmModalWindow"
 reRender="blaaaaaaa,prop"
 action="#{propertyBean.editProperty}"
 oncomplete="windowclose();"
 value="Save"/>

 <input type="button" onclick="windowclose();" value="Cancel" />
 </td>
 </tr>
 <tr>
 <td align="right" colspan="2">
 <a4j:outputPanel ajaxRendered="true">
 <h:messages id="modalError"/>
 </a4j:outputPanel>
 </td>
 </tr>
 </table>
 </modPanel:modalPanel>
 </a4j:region>
 <script language="javascript" type="text/javascript">
 //<![CDATA[
 var link = document.getElementById('modalForm:mpLastHref');
 link.parentNode.removeChild(link);

 function windowclose(){
 if (document.getElementById('modalForm:modalError')==null){
 Richfaces.hideModalPanel('modalForm:mp');
 };
 };
 //]]>
 </script>
 </h:form>

2. backing bean :

@Stateful
@Name("propertyBean")
public class PropertyManBean implements PropertyMan{

 @PersistenceContext
 EntityManager em;

 @DataModel
 List<Property> properties;

 @DataModelSelection
 private Property selectedProperty;

 boolean propertyCount;

 @In(create=true)
 Property property;

 @In Identity identity;

 public List<Property> getProperties() {
 properties = (List<Property>)em.createNamedQuery("Property.findAll").getResultList();
 setSize(properties.size());
 return properties;
 }

 public void setProperties(List<Property> properties) {
 this.properties = properties;
 }
 public void editProperty(){
 Users user = (Users)sessionContext.get("currentUser");
 System.out.println("user = "+user);
 System.out.println("property = "+property);
 System.out.println("property = "+property.getPropertyName());
 }
 public void removeProperty(){
 System.out.println(selectedProperty);
 System.out.println(selectedProperty.getPropertyName());
 System.out.println(selectedProperty.getId());
 }

 public void addProperty(){
 try {
 property.setRecStatus(new Long(1));
 property.setRegDate(new java.sql.Date(System.currentTimeMillis()));
 property.setRemark("Property Parameter For User");
 ...................................................................................
 em.persist(property);
 } catch (Exception e) {
 FacesMessages.instance().add("Could not Register. Please Trye Again");
 }
 }

 @Remove
 @Destroy
 public void destroy() {}
}

i have addproperty action outside modal panel and it works, but edit property into modal panel does not work, into backing bean, there is not property field values :(


i like modal panel component so much and want to use it.
can anybody help me ?
is there anything incorrect ?
