Testing for undefined and null child objects in ActionsScript/Flex
- by dbasch
Hi Everyone,
I use this pattern to test for undefined and null values in ActionScript/Flex :
if(obj) {
execute()
}
Unfortunately, a ReferenceError is always thrown when I use the pattern to test for child objects :
if(obj.child) {
execute()
}
ReferenceError: Error #1069: Property child not found on obj and there is no default value.
Why does testing for child objects with if statements throw a ReferenceError?
Thanks!
