Answer 1

You could use the Global Primefaces Tooltip; You just need to change your approach to setting the header text, using the <f:facet/> rather than the headerText attribute. Using your code sample

   <p:tooltip/>

   <p:columns value="#{model.columns}" var="column" columnIndexVar="colIndex"
        headerText= styleClass="#{column.styleClass}" width="#column.width}" sortBy="#{(element[column.productId])[column.property]}">
     <f:facet name="header">
          <h:outputText value="#{column.header}" title="#{column.header}"/>
     </f:facet>
        <h:outputText value="#{(element[column.productId])[column.property]}" title="#{(element[column.productId])[column.property]}"/>
   </p:columns>

Two things have happened

1. I've defined a global <p:tooltip/>
2. Using the HTML-standard title attribute on the header facet text. This is what hooks into the global tooltip, to display tooltip text per column
