Sven Meier commented on WICKET-4620:
------------------------------------
If your page is stateless, there won't be a 5th row present when the next
request comes in.
What type of component do you use for the links?
> Ability to choose the child ID for repeating views and the row ID for
> DataTable

> We are extensively using stateless behaviour in our application.
> Because our pages are stateless, we can't rely on the IDs for rows being the
> same between two visits to the same page - something might have happened to
> shift the rows up or down such as another user inserting or removing rows.
> Because of this, I would like to use the ID of our actual model objects as
> the child ID, but there are two barriers to achieving this:
> 1. Even though newChildId() in RepeatingView is public, it isn't passed the
> model object so I can't derive the ID from the model object.
> 2. Even though I could extend DataGridView, I can't customise my DataTable
> subclass to return the subclass because it's being constructed in the
> constructor.
