Subject [jira] [Commented] (FLEX-34084) Error with PopupButton/Menu in headerrenderer in DataGrid
Date Thu, 13 Feb 2014 22:48:21 GMT

    [ https://issues.apache.org/jira/browse/FLEX-34084?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13900832#comment-13900832
] 

Justin Mclean commented on FLEX-34084:
--------------------------------------

The issue is likely that in 4.11 any RTE in an item renderer or header would would be caught
and not reported. Removing the try catch improved performance and shows up any real issue
in item renderers / item headers making development easier. May have to rethink that change
or at leafs provide a way to revery to previous behaviour and silently catch all errors.
