paging methods (htmlDataTable)

[Joe Shannow]

Hello,

I have some methods for paging h:dataTable (htmlDataTable binding) and several dataTables with different properties (PERSON - id, name, adress or PRODUCT - id, value, quantity, etc.).
The pagging methods are still the same, for example:

private HtmlDataTable dataTable;
  
public void pageFirst() {  
  dataTable.setFirst(0);  
}  

(same code in myPerson and myProduct class)

called from jsf:

<h:dataTable binding="#{myPerson.dataTable}"
                 value="#{myPerson.dataList}">
resp.
<h:dataTable binding="#{myProduct.dataTable}"
                 value="#{myProduct.dataList}">

but I'm not able to call them from one class.
When I use it from one dataTable (for example person) it works, but after changing a xhtml page (product), it doesn't.
It's looking for PERSON properties but I'm try to show PRODUCTS.

So I have to have all paging methods twice........
How can I use it from one class?
