Hi Thilo, Thanks for this. I tried Thiago's solution and had some problems with it not remembering the values which were set. I'm not entirely sure why that is. I think creating a component is the ideal solution, but it seemed a little overkill at first.
I also noticed on StackOverflow that someone (Lance Java) posted a useful response that I need to try, but I do think it's going to have to go into it's own component and I need to study ajax loops, although being able to add/remove rows isn't entirely necessary for the project at the moment.
