Ugly JSF Code

Question

Hello,
I want to delete an entity that is referenced by a GET id attribute. I want to add a button/link in the web page to do this job.
I did it using the JSF expression language and the h:outputLink referencing to a Servlet:
<h:dataTable value="#{price_controller.allPrices}" var="current_price">
<h:column>
<f:facet name="header"><h:outputText value="Remove"/></f:facet>
<h:outputLink value="remove_price?price_id=#{current_price.id}&product_id=#{price_controller.productId}">
Remove
</h:outputLink>
</h:dataTable>
¿Is there any way to have the logic in a Managed Bean instead of a Servlet?
It seems that the only way to do that is using the h:commandLink/h:commandButton but I don't know how to send the "#{current_price.id}" information.
Thanks,
Pau

Your JSF:
<t:dataTable value="#{myBean.records}" id="results"
  var="showRecos" binding="#{myBean.recordsTable}">               
  <t:column width="8%">
    <h:commandButton id="button" action="#{myBean.myAction}"
      image="/images/folder.gif"/>
    <h:outputText id="recordId" value="#{showRecos.recordId}"/>
  </t:column>
  <t:column>
      <h:outputText id="recordData" value="#{showRecos.someData}"/>
  </t:column>
</t:dataTable>In your Bean:
//Variables
private ArrayList<RecordBean> records;
private UIData recordsTable;
//Add getters and setters to the above variables
//Action
public String myAction(){
  try{
     RecordBean recordBean = (RecordBean) recordsTable.getRowData();
     System.out.println("****Selected Record****");
     System.out.println("Record Id:"+recordBean. recordId);
  }//Followed by catch, finally
}
