    Richfaces datagrid having selectmanycheckbox and a4j command

    sarfaraz Mandal Newbie

      Our application requires results to be displayed in grid as provided by rich: datagrid. Further each element in datagrid has dynamically generated checkboxes and a commandbutton to add the selected checkbox.

      Following is my code:

       <rich:dataGrid id="resultsAtOnce" value="#{searchResultsForAtOnce}" var="res" columns="4" elements="20" width="600px" >
       <rich:panel bodyClass="pbody" onmouseover="this.className='highlight'" onmouseout="this.className='normal'">
       <f:facet name="header">
       <h:outputText value="#{res.catalogId}" />
       </f:facet>
       <ui:include src="popup.xhtml" />
       <h:outputLink value="#" id="link">
       Details
       <rich:componentControl for="panel" attachTo="link" operation="show" event="onclick"/>
       </h:outputLink>
       <h:panelGrid columns="2" >
       <h:outputText value="Style Number" styleClass="label"></h:outputText>
       <h:outputText value="#{res.styleNbr}" />
       <h:outputText value="Color " styleClass="label"></h:outputText>
       <h:outputText value="#{res.colorNbr}" />
       <h:outputText value="Style Name " styleClass="label"></h:outputText>
       <h:outputText value="#{res.styleName}"/>
       <h:outputText value="Price " styleClass="label"></h:outputText>
       <h:outputText value="#{res.price}" />
       <h:selectManyCheckbox value="#{cartAction.cc}" id="check" >
       <f:selectItems value="#{res.colorCodes}" />
      
       </h:selectManyCheckbox>
       <a4j:commandButton id="addToCart" value="Add to Cart" actionListener="#{cartAction.addToCart}" >
      
       </a4j:commandButton>
      
       </h:panelGrid>
       </rich:panel>
       <f:facet name="footer">
       <rich:datascroller renderIfSinglePage="false" ></rich:datascroller>
       </f:facet>
       </rich:dataGrid>
      


      There are few technical aspects that I am stuck in:
      1. Ability to identify the selected element in the datagrid.
      2. Only the last element in each page is working normally as expected. That is on selection of checkboxes in elements in datagrid other than the last in the page, and subsequent clicking on the Add to Cart Button; the checkbox selections are not read.

      I am using richfaces, seam.

      Following is the seam component code.

       }
      
      
      
      }
