We wanted to switch all our mx forms, to spark, but the new errorTip is resizing the form and it looks terrible...
Is there any easy way to have mx-like errorTips is the new spark forms?
As said in the doc ( http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/mx/ controls/ToolTip.html ) Tooltips (and errorTips) dont have a mobile skin... You could create your own skin or create your own componant... The errorTip componant is pretty basic and a custom copy could be done without too much effort imo...
Solution was a little diffirent.
To achive the old mx error tooltips, we have to override the default FormItemSkin.mxml and modify it:
1. Remove the errorTextDisplay component
2. Set contentGroup showErrorTip to true
