Hi there,
What I want to achieve:
I want to make a wizard which goes from one step to another and saves a
complex object between all these requests. I thought about FlashScope
but it does not work the way I want.
I have troubles when using the FlashScope - approach to store Objects
between two requests. The problem is, that the ActionBean which I flash
is not populated in the next request. Which means, regarding to the
example at the end, when the method "step2" is called, the Set is null.
But why?
Anyone an idea how to store and repopulate ActionBeans for using ONE and
the SAME instance for the whole wizard?
Thanks in advance,
Regards,
Christoph
WizardTestActionBean.java
/*---------------------------------------------------------*/
public class WizardTestActionBean extends BasicActionBean {
private Set<String> setToLife = null;
@HandlesEvent("step1")
public Resolution performStep1(){
setToLive = new HashSet<String>();
setToLive.add("Hello");
setToLive.add("There");
return new RedirectResolution("/wizard/step2.jsp").flash(this);
}
@HandlesEvent("step2")
public Resolution performStep2(){
if(setToLive == null || setToLive.size() != 2){
System.err.println("setToLive not populated");
return getContext().getSourcePageResolution();
}
return new RedirectResolution("/wizard/step3.jsp").flash(this);
}
}
