23308 2013-09-20 18:07:11 +0000 [Custom]: Don't queue callbacks for an element that does not have that specific callback 2013-10-04 20:26:22 +0000 1 1 1 Unclassified WebAppsWG HISTORICAL - Component Model unspecified PC All RESOLVED INVALID P2 normal --- 14968 1 dominicc dglazkov public-webapps-bugzilla oldest_to_newest 93605 0 dominicc 2013-09-20 18:07:11 +0000 If a Custom Element doesn't have a specific callback (eg leftView) that element should not be scheduled under the relevant condition (eg removed from document). This is for two reasons: 1. If we add callbacks in future, we don't want to change the order existing code sees existing callbacks. 2. It is faster to not put an element on the processing stack, etc. 94329 1 dglazkov 2013-10-04 20:26:22 +0000 This is already in place. In https://dvcs.w3.org/hg/webcomponents/raw-file/tip/spec/custom/index.html#dfn-enqueue-lifecycle-callback: * Let CALLBACK be the callback, associated with the key NAME in CALLBACKS * If there is no such callback, stop.
