Hi all,
Just a quickie...
I want to return the same page a user is viewing after he clicks a
directAction.
Why a direct action? If the page is the result of a component action,
why not use a component action.
Specifically I'm talking about a language switch link in the
pageWrapper to change languages. I want a simple url like http://www.domain.com/cgi-bin/WebObjects/App.woa/wa/English
What I'm doing atm is adding a link with the following binding:
LanguageLink : WOHyperlink {
directActionName = aLanguage;
?contextID = context.contextID;
}
And then in my DirectAction.class I'm intercepting it with:
public WOActionResults performActionNamed(String anActionName) {
...
// Do the language switching here
...
String stringContextID = (String)req.formValueForKey("contextID");
return s.restorePageForContextID(stringContextID);
}
This mostly works... but sometimes I get errors since for no
apparent reason the WOHyperlink does not include the ?contextID
thing sometimes.
Am I doing it correctly?
I just want the equivalent of returning null on a component based
action.
I'd look in the headers for the referrer URL and use a WORedirect to
that.
