[jira] Created: (TAPESTRY-1601) The no-params onActivate() method
is called even if a context is supplied
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

This is by design.
Events are no invoked in descending order by number of parameters. This should help you determine the intent.
