[jira] [Commented] (TAP5-1956) Tapestry.ZoneManager creates memory leaks

["Jochen Kemnade (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TAP5-1956?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13295658#comment-13295658 ] 

Jochen Kemnade commented on TAP5-1956:
--------------------------------------

The same leakage pattern can also be observed with other Tapestry JS classes such as Tapestry.FormEventManager, Tapestry.FieldEventManager, Tapestry.ErrorPopup and others. The clean-up hook approach could be used to fix them all.

> The Tapestry.ZoneManager creates a circular reference between the DOM tree and the ZoneManager JS object. This circle is not broken when the element is removed from the DOM, so it will not be cleaned up.
