ArcGIS For Flex Error 2, arcgisforflex Error

1. Error description



2. Error cause


3. Solution


Why is an error reported when I add flex to Arcgis?

The Flex Builder4 version is lower. Arcgis api for flex 3 and 3.1 require a later version of Flex for use. The API version 2.5 is correct!

Arcgis_api_for_flex_21

No Flex package for ArcGIS was introduced. Or there is a conflict. If you are sure you have introduced the Flex library of ArcGIS to check whether event. geometry has this feature? If event is null, this error is reported and cannot be understood.
