Hi Stephen, I strongly encourage you to create a component for your result editor. This helps encapsulating the editor code, which de-clutter your page class / template. Tapestry components are very elegant and easy to re-use.
If the number of values in your ArrayList is constant, you can use Thiago's approach and use the Loop component to create the text fields. In case the number of values should be adjustable, I think you're better off using AjaxFormLoop.

I did come across that first link when I was searching, but the issue would be that it requires a lot more work for doing something which I thought would be straight forwards. However, if I do it properly, then this form can be used in several places in the application. I think the best way would be for me to create this as a component which handles everything to do with editing the result object, and pass the "result" object in, I can name it something along the lines of "resultEditor". I would then use the ajaxloop within the component. That way whenever I want to show the result objects details and allow it to be edited (this could be used in a few places), I can just use this component which will be responsible for updating the result object. I just wanted to check with you that doing that seems like a sensible way forwards? As for the cheapo idea, although I do like it, unfortunately the text fields may want changing to text areas (as they may not be short) so if they risk going on to two lines then it becomes a bit of a nightmare for users seeing where the end of lines really are. If you think the first way is the way to go, i'll put in the time to create it as a separate component with an ajax loop in it. It seems odd that it can't be done in a simpler way, just displaying each String in the ArrayList as a separate text field/area.
