Description

When I use fx:Binding in my application It will throw this exception There's three arguments in ContainerDataBinding binding.source binding.destFunc binding.destination for Example if I am using binding in my application like this <fx:Binding source="sname.text" destination="controller.scenario.name"/> binding.source should be sname and binding.destFunc should be null and binding.destination should be controller.scenario.name But when i compile application binding.source** is sname binding.destFunc is controller.scenario.name and binding.destination is null image image

Contributor guide

Research direction
Investigate ContainerDataBinding class in royale asjs to understand how source, destFunc, and destination are parsed from fx:Binding syntax. Likely the order of arguments is being misread. Trace the parsing logic and identify where the mapping is reversed.
