The no-params onActivate() method is called even if a context is supplied
-------------------------------------------------------------------------

                 Key: TAPESTRY-1601
                 URL: https://issues.apache.org/jira/browse/TAPESTRY-1601
             Project: Tapestry
          Issue Type: Bug
    Affects Versions: 5.0.4, 5.0.3, 5.0.5
            Reporter: David Peterson


What I'm trying to do is redirect to another page, if my page has not been given any context.

Something like this:

    Object onActivate(String context) {
         if (context == null) {
              return _otherPage;
         }
         return null;
    }

Unfortunately that method does not get run if the context is missing.

I tried:

    Object onActivate() {
          return _otherPage;
    }

But this method is run even if there is a context. And it's run before the other one, so I
can't even set a flag. I've tried returning the page from setupRender() instead, but that
expects a boolean result and doesn't work. So, what do I do?


Suggested fixes (in order of preference):
- Allow a page to be returned from setupRender()
- Do not call onActivate() if onActivate(context) has already been called
- Provide another event after all the onActivate() methods have been called
