Re: Dynamic Result Selection
Hi Christian,
Thank you for your response. I had actually defined all three results,
success, input and error and My class did extend ActionSupport. But the problem
was, whenever an error occurred during Interceptor invocation, framework would
try to find value of nextPage. As action is not executed it would not find
nextPage on valueStack. So I want to know is there any way of getting around
this problem? Can I specify value for nextPage before any interceptor is
invoked?
Thanks Regards,
Rohan

try to add these results too:

result name=error%{nextPage}/result
Input is what is returned when some input is missing, error in case an
error happens.
Please also see the class ActionSupport, were these String constants
are defined. To use it, extend ActionSupport and return for example:
return SUCCESS;
Of course you don't need to use ActionSupport, but I think it is a good idea
:-)

Re: Dynamic Result Selection
Hi Christian,
Thanks again. I think I would have to write my own interceptor. I think I can
also get nextPage value from session. i.e. I can set value from my interceptor
to a session variable and also from action and then use it. I would try doing
that. And if it works out, I would certainly post it.
Thanks Regards,
Rohan

Ah, now I understand better.
Have you tried to define a default value for $nextPage in your class? Like:
class MyAction {
private String nextPage = errorpage.jsp;
Actually the action itself will not be executed if an interceptor error occurs.
If the default value does not work, I think it might be a good idea to
write an own interceptor which catches something like that or to
extend the throwing interceptor to put a correct value into the
object.
cheers

Dynamic Result Selection
Hi All,
I am very new to Struts 2, so I don't know whether this issue is
discussed before and has a solution. I had dynamic Result selection in my
project. Where result would be selected on the basis of execution logic in
Action method.
For Example something like,
action name=test class=myPackage.Test
result name=success%{nextPage}/result
/action
Where nextPage would be a property in Test class with settter and getter
methods. And I would set it to whatever jsp page I want to execute.
It would work fine if Action method is successfully executed.
But the problem was that, if something happened and Action could not be
executed, then result would not get invoked. i.e. if validation interceptor
found validation errors or my RolesInterceptor found that user does not have
access to that method.
Framework would throw exception that result not found.
What can be done here?? Can I set a default nextPage before Interceptors are
invoked?? Could writing an Interceptor for that help??
I know that as I am new to Struts 2 I could be doing something wrong. Can
anyone help me??
