Subject [jira] [Commented] (FLEX-33865) ConstraintLayout / LayoutElementHelper are memory inefficient (and slow)
Date Sun, 03 Nov 2013 13:42:17 GMT

    [ https://issues.apache.org/jira/browse/FLEX-33865?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13812368#comment-13812368

Maurice Amsellem commented on FLEX-33865:
-----------------------------------------

Benoit, 
That's something else, and it could probably be easily fixed by modifying the regexp (JIRA?)
I think that if the initial coders of this function used that complex  regexp processing instead
of the obvious indexOf(":"), they probably had a good reason for that, or maybe it's just
over-engineering.
Unfortunately, I don't know the history of that code, so I cannot accept a change that breaks
the current design without discussing it with the team.
I will post the discussion on the dev list and will let you know.
