thank you Kieran, That's exactly what I need!
2007/5/4, Kieran Kelleher <[EMAIL PROTECTED]>:
Each direction action is called by the performActionNamed method that
takes a String argument, so you can have dynamic whatever you want. Your
dynamic actions are just Strings and you can store them in the db along with
other metadata and write your own custom logic to do whatever you want wit
those Srting "actions".
For example, here is a simple subclass of WODirectAction that interprets
the "action name" as a page name, creates the page and pushes query
dictionaries into those pages if they implement a specific interface. Note
there is only one method taking a String param and because I never call
super, WO never creates a method name for the String to invoke a method
using reflection:
import com.webobjects.appserver.WOActionResults;
import com.webobjects.appserver.WOComponent;
import com.webobjects.appserver.WODirectAction;
import com.webobjects.appserver.WORequest;
/**
* @author kieran
*
*/
public class Show extends WODirectAction {
private static final org.apache.log4j.Logger log = org.apache.log4j.Logger
.getLogger(Show.class);
/**
* @param aRequest
*/
public Show(WORequest aRequest) {
super(aRequest);
}
/**
* @see com.webobjects.appserver.WODirectAction#performActionNamed(
java.lang.String)
* @override we override this to actually return pages named 'name'
instead of the usual
* behavior of this method which is to determine a action method name by
adding 'Action'
* and invoking through reflection
* Now we can have URLs like
* /wa/Show/MyPage?oid=2345
* Inspired by a Pierce Wetter tip.
* We also pull all the form values and stuff them into the target
component
* if it implements the RailsBehaviour interface
*/
public WOActionResults performActionNamed(String name){
// Create the page
WOComponent page = pageWithName(name);
if (page instanceof RailsBehaviour && request().formValues() != null &&
request().formValues().count() > 0){
((RailsBehaviour)page).takeValuesFromDictionary(request().formValues());
}
return page;
}
}

Hi list,
A simple question: is there a way to generate Dynamic Direct Actions?
I mean, I'm thinking about an application really simple: menu with
links, generated by a worepetition, but I wish to use only directActions
(for indexing, don't make me begin...), so I thought, there's a way to
dynamically add a Direct Action to an app, this is usefull, if i'll add a
backend for adding new links!
ah, of course direct action simply call
public WoActionResult homePageAction(){
return pageWithName("HomePage");
}
not strange things ;-)
thank you for any help,
