Modify Seam-gen default column sorting to AJAX

[gerryjun]

Hi,

Notes:
Seam-gen generated
Seam 2.2

      I need some help pls,  im trying to modify the sorting columns generated by seam-gen sortable via AJAX as per client requirement.

My problem is, it would seem that the query is being generated before the sort and dir param could be set on the entityList component.

Looking at the system.out on the getResultList() to print the orderColumn it still shows null, then after the query is generated, is the time that it gets the params for the filter.

The list is being reRender with out a problme, i have verified that the params are bieng passed, it would seem its just late.

How can i correct this?

--------------- sort.xhtml --------------

<ui:composition xmlns="http://www.w3.org/1999/xhtml">
    <a4j:commandLink  styleClass="columnHeader" value="#{propertyLabel} #{entityList.orderColumn == propertyPath ? (entityList.orderDirection == 'desc' ? messages.down : messages.up) : ''}" reRender="mainbody" ajaxSingle="true" >
        <a4j:actionparam name="sort" value="#{propertyPath}" assignTo="#{entityList.orderColumn}" />
        <a4j:actionparam name="dir" value="#{entityList.orderColumn == propertyPath and entityList.orderDirection == 'asc' ? 'desc' : 'asc'}" assignTo="#{entityList.orderDirection}"/>
        <s:conversationPropagation type="join" />  
    </a4j:commandLink>
</ui:composition>

------------------ System out from entityList.getResultList() ------------------------------

Solved it my self, by overriding the getResultList method and setting it my self from the FacesContext were the params are available but not yet set on the EntityList.

Seems to be a bug on the life cycled where param are being applied late in its cycle.

     @Override
     public List<MasterUserType> getResultList() {
           this.setOrderColumn(FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("sort"));
           this.setOrderDirection(FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("dir"));
          return super.getResultList();
     }

additional note: im using a4j:include to dynamically include the list view.

Thanks
