PageActivationContext issue

[nn kk]

 Hi,
I have the following code:
class Page1 {

  @InjectPage
  private Page2 page2;
  ...

  Object onSuccessFrom...() {
...
ListCat catList = new ArrayList...
catList.add(cat1);
catList.add(cat2);

page2.setCatList(catList);
return page2;
  }
}

class Page2 {
   @PageActivationContext
   @Property(write = false)
   private ListCat catList;

   public void setBaList(ListCat catList) {
 this.catList= catList;
   }

   void onActivate() {
//catList is null   
   }

   void onActivate(ListCat catList)
   {
//catList is null   
   }

  void setupRender() {
//catList is null   
  }
}


If I replace @PageActivationContext with @Persist, I see the list populated, 
but I don't understand how should I use the @PageActivationContext

I think I had issues trying to use an array / collection as an EventContext
item. I think I had to resort to using a comma separated string from
memory.

In your case, I think you will be able to fix it by.

1. Remove @PageActivationContext
2. Add onActivate(EventContext ec)
3. Add ListCat onPassivate()
