UIComponent and week reference to resource manager change handler

[Justin Mclean <ju...@classsoftware.com>]

Hi,

A week references to an event handler is being created in the UIComponent. 

// Register as a weak listener for "change" events from ResourceManager.
// If UIComponents registered as a strong listener,
// they wouldn't get garbage collected.
resourceManager.addEventListener(
    Event.CHANGE, resourceManager_changeHandler, false, 0, true);

Do we care that this is never removed? Being a week reference it should be garbage collected at some point but perhaps it safer if we explicitly removed it at a guess in the removed from stage handler? Anyone have any other thoughts?

Also see:
https://issues.apache.org/jira/browse/FLEX-33237

There a few other components that do the exact same thing.

Thanks,
Justin
