--------------------------------
Resolution: Fixed
> Allow custom validators to use the triggerEvent
> -----------------------------------------------
>
> Key: FLEX-34941
> URL: https://issues.apache.org/jira/browse/FLEX-34941
> Project: Apache Flex
> Issue Type: Improvement
> Components: Validators
> Affects Versions: Apache Flex 4.14.1
> Reporter: Mihai Chira
> Assignee: Mihai Chira
> Priority: Minor
> Fix For: Apache Flex 4.15.0
>
>
> The private triggerHandler() function only starts validation, without storing
> or using the event object. However, there are scenarios in which this object
> is crucial. For instance:
> There are two pathways to change the properties of an object: through a
> DataGrid itemEditor, and through a form, which are side by side. As a user I
> want to see in the grid when I have made an invalid change via the form.
> One cannot just add validators to the itemEditors in the grid, because they
> will not be instantiated if the changes happen via the form. But the red
> rectangle and errorString properties still need to be set when the wrong
> values are set.
> A solution is to have the renderers dispatch a custom bubbling event when
> their data changes, catch this event in a validator on the view that contains
> both the grid and the form, and set the source and property dynamically on
> the validator when this event occurs, so that it can effect the change to the
> border and errorString of the renderer. For this, however, we need the event
> object in triggerHandler.
