[jboss-user] [JBoss Seam] - Re: working with a dynamically sized Datamodel with JSF/SEAM

ICEFaces:

The columns component provides a dynamic model for adding and deleting columns at run time. It uses the standard var and value attributes. 

The columns component works in conjunction with the ice:dataTable. The headerClass and columnClasses defined on the dataTable component will be applied to all generated columns as it does on a single column. 

Examples 

  | <ice:dataTable var="item" value="#{columnsBean.rowDataModel}" columnClasses="columnsColumn" >
  |         <ice:columns value="#{columnsBean.columnDataModel}" var="column">
  |             <f:facet name="header">
  |                 <ice:outputText value="#{column}" />
  |             </f:facet/>
  |             <ice:outputText id="intCell" value="#{columnsBean.intValue}"/>
  |         </ice:columns>
  | </ice:dataTable> 

The columns component can be used in conjunction with a column component (e.g.) 

<ice:dataTable var="item" value="#{columnsBean.rowDataModel}" columnClasses="columnsColumn" >
  |         <ice:column>
  |             <f:facet name="header">
  |                 <ice:outputText value="id" />
  |             </f:facet/>
  |             <ice:outputText value="#{item.id}"/>
  |         </ice:column>
  |         <ice:columns value="#{columnsBean.columnDataModel}" var="column">
  |             <f:facet name="header">
  |                 <ice:outputText value="#{column}" />
  |             </f:facet/>
  |             <ice:outputText value="#{columnsBean.intValue}"/>
  |         </ice:columns>
  | </ice:dataTable>
