Uncaught TypeError: Cannot read property 'length' of null (ContainerDataBinding.js:67)

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

**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

Start at ContainerDataBinding.js:67 and inspect how the three fx:Binding arguments—source, destFunc, and destination—are assigned during compilation. Reproduce the example using source="sname.text" and destination="controller.scenario.name", then verify that the compiled binding preserves the expected values and no longer throws the null length TypeError.
