Reseting a Flex DataGrid's dataProvider when using a filterFunction

It's fairly common to have a filterFunction applied to the ArrayCollection you are displaying in a DataGrid, such as to hide deleted items:


I was also allowing users to edit and remove the displayed items; so needed a quick way for them to 'reset' all their unsaved changes, which lead to a couple of gotchas.

Mylyn Reports

I'm always saying how good the Mylyn plugin for Eclipse is, in keeping the UI focused on the task at hand.

Because it integrates with your issue tracker, the trackers reports can be used if you want a summary of what you did, or what's still left to do.

1) Include the logEventLevel parameter to SwizConfig

<swizframework:SwizConfig xmlns:swizframework="org.swizframework.*"

You'll need to import the mx.logging.LogEventLevel class.
