Flex 3.6 to 4.6/4.9 Migration issue

问题

I am getting the following error while migrating to version 4.6/4.9. Same thing works fine in flex version 3.6.

Can somebody please help me to resolve it?

回答1:

You are passing a String "/" in a CartesianChart somewhere in your code where it expects a DisplayObject

Type Coercion failed: cannot convert "/" to flash.display.DisplayObject.
