How to get the name of last visited page?

[Serethos]

Imagine I have written two pages and linked them to two Java-classes, both WOComponents. The first page has a dynamically created link to the second page and calls it via pageWithName(..). How can I find out the name of the calling page within the second (target) page?

Let your components inherit from a custom parent that implements sth.  
like:

     public WOComponent lastPage;

     public WOComponent pageWithName(String name) {
         WOComponent page = super.pageWithName(name);
         if (name.equals(this.name()))
             page.takeValueForKey(this.lastPage, "lastPage");
         else
             page.takeValueForKey(this, "lastPage");
         return page;
     }

     public WOComponent lastPage() {
         return lastPage;
     }

     public boolean hasLastPage() {
         return (lastPage == null ? false : true);
     }

HTH
