wrong row deleted in datatable
I am trying to create a datatable with a delete link in one of the datatable column, using rowKeyVar to label the row index in the link. After I added two rows and click the delete link on the first row, the second row is deleted. I can see the values that the action listener picks up is correct. Here is the code:

</html>Order.removeItem():
public String removeItem(){
String value = (String) FacesContext.getCurrentInstance()
.getExternalContext().getRequestParameterMap().get("id");
int index = Integer.parseInt(value);
lineItems.remove(index);
return "success";
}I saw the same problem with tomahawk. The example is adapted from tomahawk code. Am I missing something?
