Though that is true, it can be avoid if you write your chainer properly. You can have it "Dechain" and actually invoke a forward to the new action.
Also, you can write an Action that just invokes objects in a linked list mannor and have each action called that way. There are really lots of options for chaining.... As stated in an email a week or so ago, I have a system that does all of the above and more but I'm still trying to get permission from my company to release it :( -- Sloan ----- Original Message ----- From: "Siva" <[EMAIL PROTECTED]> To: "Jing Zhou" <[EMAIL PROTECTED]> Cc: "Struts Users Mailing List" <[EMAIL PROTECTED]> Sent: Tuesday, July 22, 2003 10:28 AM Subject: Re: Why not to use Action chaining ? > thanks a lot Jing Zhou, > I will try this . > > Siva > > Jing Zhou wrote: > > > ----- Original Message ----- > > From: "Siva" <[EMAIL PROTECTED]> > > To: "Struts Users Mailing List" <[EMAIL PROTECTED]> > > Sent: Tuesday, July 22, 2003 5:14 AM > > Subject: Re: Why not to use Action chaining ? > > > > > Thanks Alen, > > > > > > Ted Husted (Struts in Action) says that the action chaining in the dark > > side > > > of Struts. > > > > > > The problem he mentioned is that > > > > > > "when the second action is being invoked, the form is being 'repopulated' > > > with the initial form values that the form had when it was passed to the > > > first action " > > > > > > Since I am new to struts, I am not able to grasp it clearly.
