Pardon the disheveled nature of this response :/ Whether or not the image object need to be "recreated" is more an issue w/ your persistence mechanism, but you'll at least need some sort of UID for each.
On the S2 side you can create a map keyed on the UID and expose whatever properties you want (like an object.metadata field or just a string or whatever) and use map notation on your form. Check out the wiki page on type conversion to see a bit more about how maps can be used: http://struts.apache.org/2.x/docs/type-conversion.html It's down towards the bottom. In a nutshell you can do something like (pseudotag): <s:hidden name="theMap[aUid].id/> // To recover the UID on form submission <s:textfield name="theMap[aUid].metadata"/> where the map is: Map<UidClass, ImageClass> _theMap; with an appropriate getter. On submission your map will be filled in w/ the form's values, the next step depends a bit on your persistence mechanism. d. --- Mark Steyn <[EMAIL PROTECTED]> wrote: > Forgive me is this is a very obvious question, but > I'm new to struts 2, > and despite googling around, I'm still not sure as > to how to do > something. > > I'm trying to accomplish the following: > > 1.
