Howard M. Lewis Ship resolved TAPESTRY-1601.
--------------------------------------------
Resolution: Invalid
Assignee: Howard M. Lewis Ship
This is by design.
Events are no invoked in descending order by number of parameters. This should
help you determine the intent.
> 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: 5.0.3, 5.0.4, 5.0.5
> Reporter: David Peterson
> Assignee: Howard M. Lewis Ship
>
> 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
