I guess it's also easy to swap objects between the two models as well, this would be a nice addition to the example to allow bananas to be swapped between bunches. I did notice the new banana before but I wanted it to take values from fields on the form but I guess this is very simple to do now. It solves my problem in theory at least : ) all I have to work out now is how to maintain a tree in Struts :( I don't think the applet way is a very nice way of doing it.

To write the monkey example in Struts without the nested tags is verging on impossible, at the very least a truly large headache, it was really quite easy. If the nested tags are guilty of anything, they make it very easy (and even fun?... maybe I'm wired differently) to add more and more complexity to the structure. The nested tags have made some truly unwieldy applications, including the reason for their creation. You just have to ask yourself one question...
