Implementing a back button without Javascript
Hi all,
we're using struts 1.2.4 in our project and I'm trying to implement a
back button for a 3 step registration procedure. The problem is I'd
like to do it without using javascript. I've discovered html:cancel
which works nicely for ...canceling. But I couldn't find anything similar
for the back button. Any ideas?
Thanks

The way is simpler than you may think :-)
You can create a new *form*, different from the main one, in which there is
an <html:submit> button that triggers the action that takes you "back".

The first case would suit me fine. But how would I do this exactly? Use
a simple button instead of <html:button> and include it in a <a> element?
I'm trying to do this as uniform as possible as with the other buttons
which are <htm:submit>, <html:reset> and <html:cancel>.
My current code looks like this:
<a href="<%=request.getContextPath()%>/home.do">
<html:button styleClass="button" property="back">
<bean:message key="prompt.back.button" />
</html:button>
</a>
but I still need to add a back property to the form bean which is not
really needed.

You need to manage it on the server side. There are many ways to do it, just
to mention a pair:
1) the button points to the previous action;
2) implement a history manager that manages the history of called actions
and, when called "back" (e.g. with a "history action") you go back in the
history.

If you don't want to add another form element to the page you could take a look at LookupDispatchAction's getKeyMethodMap() method. Extend LookupDispatchAction in your action class. Override the getKeyMethodMap in which you can map your button's keys to methods you create. You could create a mapping for your "prompt.back.button" to a goBack method. In goBack() you can do whatever processing you might need to "undo" things, then return a forward name that you map for it in your struts-config file.
