Redirect List Parameter
Hello All,
I have a typical scenario:
1. User is presented a list of orders, and can select some of them
to complete. A list of order numbers is sent to the next action.
(ViewOrders.action)
2. Struts action completes the order by iterating through the list
of passed order numbers. (CompleteOrders.action)
3. The user is redirected to a confirmation action, listing the
orders that were completed. (CompleteConfirmation.action)
The question I have is getting from step 2 to 3.
This is a fairly standard redirect-after-post setup, but I want to
be able to redirect to a confirmation action and pass a parameter list.
Essentially what I want is:
<action name="CompleteOrders" class="test.CompleteOrdersAction">
<result name="success" type="redirectAction">
<param name="actionName">CompleteConfirmation</param>
<param name="namespace">/test</param>
<param name="orderNumbers">${orderNumbers}</param>
</result>
</action>
Resulting in a redirect to:
test.com/test/CompleteConfirmation.action?orderNumbers=1&orderNumbers=2&orderNumbers=3&orderNumbers=4
However, this doesn't seem to work. Has anyone found a way to do this?
I realize there are ways to do this by using the session, but Id
prefer to pass this through the URL if possible.
Thanks,
Tim

Yeah, I think my best option here is to just convert my list of ints to
a comma separated list. It seems though, that since the request object
can handle lists, that there should be a way to add list parameters in
struts.
Right now the function to add a parameter in ServletRedirectResult looks
like:
public ServletRedirectResult addParameter(String key, Object value) {
requestParameters.put(key, String.valueOf(value));
return this;
}
But it seems that maybe there should be one to handle something like a
list of strings. Right now adding a list as a parameter just results in
the java toString of it, which isn't much help.
Anyways, thanks for the help.

Re: Redirect List Parameter
Posted by Greg Lindholm <gr...@gmail.com>.
If you are using a result type of "redirectAction" you don't
explicitly code the url just give it the action name and let the
result construct the correct url.
To pass parameters with a redirectAction you do it like this:
<result name="success" type="redirectAction">
< param name="actionName">CompleteConfirmation</ param >
< param name="orderNumbers">${orderNumbers}</ param >
</result>
(hopefully the above param tags come thru correctly, some mailing list
readers like nabble muck-up param tags.)
You will need to ensure the ${orderNumbers} can be converted to a
meaningful string so that it can be encoded as a url parameter. And
the target action will need to be able to convert the string back into
a collection.
You will also need to be aware that there are length limits to url's
so if orderNumbers is too big you can have problems.
It may be a a better idea to just save the orderNumbers in the session
(or some other cache) instead of passing it as a parameter.

Re: Redirect List Parameter

Right, this is similar to what I want, but it would have to be
dynamically generated, as I don't know the size of the list. For
instance, in this case, the user would have selected 4 orders, but in
the next case could select 10. The problem isnt passing parameters, it's
passing a parameter thats a list.

Timothy,
If I understand you correctly you want to redirect and pass values. I
have done this by encoding my url with proper html syntax.
<action name="CompleteOrders" class="test.CompleteOrdersAction">
<result name="success" type="redirectAction"
s>test/CompleteConfirmation.action?orderNumber&${orderNumbers}</result>
> </action>
I hope this helps.
