Anil,
There is no way you can specify the name of an outcome just once and use
a reference to it both in the java-code of your managed-bean and the
navigation-rules in your faces-config.xml. Since your faces-config.xml
doesn't get build or compile, there is no way to garantee that the
values used for outcomes are 'valid' and match the String you use in the
managed-bean.
For me it works fine to create a Outcomes-class which contains a set of
static final String for all outcomes I use through out the entire
application. It allows to reference to those outcomes in your
managed-bean and set JavaDoc on the outcome-constants to spefify the
String to use in the faces-config.xml.
public class Outcomes {
/**
* Outcome use to proceed to the next step in a wizard: "continue".
*/
public static final String CONTINUE = "continue";
}
managed-bean:
public String someMethod() {
return Outcomes.CONTINUE;
}
This doesn't prevent you from making mistakes and errors in typing the
value for from-outcome, but does offer you the possibility to re-use
your code better and made changes easier by allowing you to refactor
your code instead of performing 'global' search and replace-action on
your Strings used as outcomes.
With kind regards,
Marco Beelen

Subject: OT: from-outcome value
Folks,
Has anyone devised or know of a pattern to be able to use a reference to
a constant string or property file in the from-outcome tag of a
navigation-case instead of 'hardcoding' the actual string there?
My objective here is to maintain a common repository of outcomes either
in a class or property file and refer to them from both the action
method and the navigation case.
Thanks - Anil.
