Howard M. Lewis Ship reassigned TAP5-1198:
------------------------------------------
Assignee: Howard M. Lewis Ship
> A user defined activate event handler appears to execute *before* the event
> handler supplied by @PageActivationContext, making defensive coding impossible
> ----------------------------------------------------------------------------------------------------------------------------------------------------------
>
> Key: TAP5-1198
> URL: https://issues.apache.org/jira/browse/TAP5-1198
> Project: Tapestry 5
> Issue Type: Bug
> Components: tapestry-core
> Affects Versions: 5.2.0
> Reporter: Howard M. Lewis Ship
> Assignee: Howard M. Lewis Ship
>
> A common technique is to provide a no-argumentes activate event handler
> method that can check to see if the PAC is null, and return a page (or other
> redirect causing result). However, since the @PageActivationContext-related
> event handler executes too late, the field will always be null when that
> method executes.
> Workaround: Don't use @PageActivationContext
