Resolution: Duplicate

Duplicate of TAPESTRY-1805.
> Render phase short-circuiting is not implemented for methods of the same phase.
> -------------------------------------------------------------------------------
>
> Key: TAPESTRY-1662
> URL: https://issues.apache.org/jira/browse/TAPESTRY-1662
> Project: Tapestry
> Issue Type: Bug
> Components: tapestry-core
> Affects Versions: 5.0.5
> Reporter: Nick Westgate
> Assignee: Howard M. Lewis Ship
> Priority: Critical
>
> According to the docs on render phase short-circuiting for methods of the same phase:
> http://tapestry.apache.org/tapestry5/tapestry-core/guide/rendering.html
> "If a method returns a true or false value, this will short circuit processing.
> Other methods within the phase that would ordinarily be invoked will not be invoked."
> This is currently unimplemented. (Only other "inner" phases are short-circuited & not invoked.)
> Changes would primarily affect:
> org.apache.tapestry.internal.structure.ComponentCallback
> org.apache.tapestry.internal.structure.ComponentPageElementImpl
> In ComponentPageElementImpl.invoke(...), the loop:
> while (i.hasNext())
> callback.run(i.next());
> needs to implement the short circuiting, for example:
> while (i.hasNext())
> if (callback.run(i.next()))
> break;
> This change would cascade up to ComponentCallback and all its usage in ComponentPageElementImpl.
> Cheers,
> Nick.
