Issue: Action redirect do not include parameter as complex objects?
Hello,
I have tried an example in which i have inserted a user using insert method
of UserAction class.
On insert I have redirected the success to loadAdd method of UserAction.
During redirect I have passed the parameter as
<param name="user">${user}</param>
In struts 2.0.14 this gives an ognl exception.
whereas when I pass
<param name="user.id">${user.id}</param>
it works.
My observation says this is a bug in struts or ognl that it does parse
composite objects while it parses simple data types.
Any work-around please suggest.
Or
Is there any way by which I can forward the complete action context or value
stack in the redirected action
With Best Regards,

Doesn't matter (and if your caching is configured properly, shouldn't
do a round-trip anyway).
Look at a browser request--the only thing you can send is strings. Period.

It's called "session scope". You can keep things in it.

Ok.
1, Why I need to pass the object and not the id.
--> I have just inserted it and do not want additional reads from database.
2. Can't image url & get request.
--> Exactly. Why do we have just GET here, can't we have post also.
3. Old version.
--> Applications can't be upgraded for every version released so best stable
release of struts2 is used. i.e 2.0.14
4. Important. Can't we have a work around to forward the value stack to the
redirected action without using action chaining, but having somewhat similar
effect.
?
5. Why can't we post values through redirect action, any work around to do
that?
?

I can't resist to imagine a connection pool that pass over a get request :)

Not to mention that's not how URL parameters work--all you can send is strings.

Aside from you're using an old version of S2, I don't think your approach is
the best one. Why should you pass every parameters? You could simply pass
just the id and then load the user object inside your loadAdd method.

Don't do it that way. The design is flawed.

Disclaimer: there are reasons why this is not common.
That being said: Use the session or application scope to store the object and
pass a token/key to the item stored in the url.
