Here's a simple enough example of how to use the <sj:a> tag available in
the struts2-jquery plugin (v 3.2.1)
http://www.weinfreund.de/struts2-jquery-showcase/index.action
Well what I get though is somehow mysterious (to me).
The first time when I call the action [1] given by its URL
http://localhost:8080/myApp/test/me
I get the correct server response, that is
- a line saying "Echo: Hello me!"
- underneath it a textfield containig the phrase "Hello me !"
- followed by a submit button
This is what it looks like:
Before: http://i40.tinypic.com/vf8782.jpg
Nice.
But after I submit the form the textfield and the submit button get
somehow mysteriously duplicated! (but not the "Echo:..." textline)
So there's still the initial textfield with the updated Hello +
whatever-you-typed-in phrase but yet another textfield and yet another
submit button.
The only difference I can tell between the initial and the duplicated
textfield is that the latter never gets a refresh.
It always contains the initial "Hello me !" phrase.
This is how it looks like after the submit:

Maybe someone can tell what I'm missing here.
Thanks!
