Hi,
we needed some more sophisticated redirection handling and I implemented it,
based on ServletRedirectResult / ActionChainResult. I was asking if we are
alone with our need for it. If not (say HERE loud and clearly :-), I will
send it over...
In our application we have lots of edit->store->edit or edit->delete->overview
action chains for various business entities. But there is a little problem
with the chain result type, because when store.action chains go edit.action
on succes, the current URL remains xyz/store.action. Not very pleasant for
the lovers of browers reload / back button...
Alternative is to use a redirection, and, of course, there is a suitable
result type redirect, but... it only takes complete http location as
arguments and knows nothing about actions and namespaces. So if you define a
package with its own namespace, say one namespace for each business entity,
having nearly almost an edit, store, delete and overview action per
namespace, it would be nice to configure the redirection just like you do
when using chain.
So I implemented action handling for redirect result type triggered by the new
parameter actionName, analog to the chain result type. When the actionName
parameter is given, the namespace will be resolved (if staying in local
namespace), and .action is appended to construct a valid url for redirection.
If instead the old location parameter is set, nothing changes to former
handling of redirection. To give an example:
<package name="gadget" extends="default" namespace="/gadget">
<action name="edit" class="de.aixcept.foo.GadgetActions" method="edit">
<result name="success" type="dispatcher">
<param name="location">/WEB-INF/jsp/gadget/edit.jsp</param>
</result>
<interceptor-ref name="defaultStack"/>
</action>
<action name="store" class="de.aixcept.foo.GadgetActions" method="store">
<result name="error" type="dispatcher">
<param name="location">/WEB-INF/jsp/gadget/edit.jsp</param>
</result>
<!-- Redirect to edit ection in same namespace on success -->
<result name="success" type="redirect">
<param name="actionName">edit</param>
</result>
<interceptor-ref name="defaultStack"/>
</action>
<action name="lookup" class="de.aixcept.foo.GadgetActions" method="lookup">
<result name="success" type="redirect">
<param name="location">http://www.gadgetfarm.org/lookup/</param>
</result>
<interceptor-ref name="defaultStack"/>
</action>
</package>
Anybody else needing it?
Regards,
- Rene
