Coding problem in ActionScript
The following code generates a VerifyError when getInstance is called.
VerifyError: Error #1030: Stack depth is unbalanced. 0 != 1.
at SingletonTest$iinit()
public class SingletonTest
{
private static var s_singleton:SingletonTest = null;
public static function getInstance():SingletonTest
{
if (s_singleton == null)
s_singleton = new SingletonTest(); //Fails at this line.
return s_singleton;
}
public function SingletonTest()
{
super;
try
{
}
catch (e:Error)
{
}
}
}
Can you guess why?
The reason is the super call in the constructor which is missing the () !
Why wouldn't the compiler throw a error or ignore the statement?
