you need to use some trickery when adding/removing columns if you want this thing to work in a form. see my recent change to datatable or one of its parents where i changed refreshingview used to render columns to repeatingview to make it work right in forms.

I have been working on a small Wicket application where I use the datatable in a highly dynamic way: the columns can be added and removed at runtime. This is working out really nicely with one caveat: the columns are defined as arrays instead of lists. In order to make this work I had to duplicate the datatable hierarchy from the AbstractDataGrid (iirc) and reimplement the toolbars. This was of course not too much work, but I think this is a valuable addition to the repeaters package. I'm not sure if it is a good idea to implement this change now, because of: * the feature freeze * the fact that in Java 1.4 the collections are not typesafe: List is not List<IColumn> The pros are: * it makes the component dynamic in the way Wicket is intended to be * it opens the ability to make really dynamic UI's * it is dead sexy when you use Ajax to add and remove the columns Is there a reason why the columns is implemented as an array instead of a collection that I am not aware of?
