Lets say we've a form with an edit, save, add, delete and various other bits n pieces. Or do you have to use links?
In fact i've tried this using links and any nested beans get dropped using lazy list or not.

Hello Mark,
I have used the same approach(1 action per functionality..So 3 different actions for insert/update/delete)
But I have never used session scoped forms.
I am not sure why do u need to have session scoped forms?
Also as far the design decision about which way is better(1 action for CRUD operations or different actions),there are different opinions on this mailing list.Some people find it easier if 1 action is doing all related operations.they just provide different methods on same action and use DispatchAction(or some similar in struts) which will call the correct method on the called action using reflection, depending on the value of parameter passed.
So it is upto you to decide which style suits you better.
With approach one(1 action per functionality..So 3 different actions for insert/update/delete), you have very atomic actions which can be reused indenpendtly very easily.But you have too many action mappings to define.
With approach 2, you have less Action mappings to deal with.
HTH.

Sure but I found that you need to always need to scope to session. And/or have links in you forms. Or create a javascript dependency changing the action.
or have you a way aorund this problem using actions?

we have found that implementing 1 action for add 1 action for edit etc... is better from the standpoint of maintainability. (it's easier to find the edit code if it's in the edit Action) we avoid code duplication by making abstract actions that contain the duplicated code
ie.
AbstractPersonAction - contains common code for person creation update delete, etc... AddPersonAction - add specific code EditPersonAction - edit specific code
btw. we also try to keep 3 seperate jsps. this may seem like more work but the complications that can arise from having too many <choose> tags in your jsps to switch between modes outweigh the addition overhead of extra jsps in the long run.

Hello. I have an action class to create, edit and remove a Person, for example. Is this a poor decision? I mean, should I create 3 action classes, one for create, another for edit and another one for remove? Does struts have a mechanism to help me in that? Thanks all.
