Andreas Andreou resolved TAPESTRY-330.
--------------------------------------
Resolution: Won't Fix
Use dojo to trap the unload event and execute as much js as you'ld like!
> Add uninitialization tag to Script specification and component
> --------------------------------------------------------------
>
> Key: TAPESTRY-330
> URL: http://issues.apache.org/jira/browse/TAPESTRY-330
> Project: Tapestry
> Issue Type: New Feature
> Components: Framework
> Affects Versions: 4.0
> Environment: All
> Reporter: Andreas Andreou
> Assigned To: Andreas Andreou
> Priority: Minor
> Fix For: 4.1.2
>
>
> The uninitialization tag will enable components and pages to
> have custom javascript executed when the page unloads.
> I am aware of many use cases where this is useful, but here is one I recently
> came across:
> Assume that a StylesheetSwitcher component exists (it does :) ) which
> allows the user to
> change the skin of a web-app. It does this by providing special javasript
> links that do the work.
> However, in many browsers, the user can change the skin from the browser
> menu. Of course,
> this action does not trigger any custom javascript. However, if we could have
> some script executed
> when the page unloads, we could determine if the user has performed the above
> action, and
> act appropriately!
>
> I expect this new tag to be used just the way the initialization tag is used.
> Also, implementing this requires nothing more than duplicating the existing
> code that
> allows the initialization feature.
