Flash Builder 4.7 conditional compiling failed

Question

I installed Flash Builder 4.7 on my windows xp machine, and tried to migrate projects from FB 4.6. However in one of my projects I use conditional compiling, but I'm getting errors.For example in FB 4.6 I have this sample code:
public class MyClass{
     CONFIG::DEBUGGING{
          import com.package.SomeClassOnlyForDebugging
     function someFunction():void{
          if (CONFIG::DEBUGGING){
               SomeClassOnlyForDebugging.create();
When I compiled it in FB 4.6 everything worked fine. However when I try to compile it in FB 4.7, then I get error on the conditional compiling only inside the function and not on the import statement. The only way I have found to overpass it is to go to Project>Properties>ActionScript Compiler and disable Enable strict type checking. But this is not a permanent solution.
Am I doing something wrong, or is there some other way to do it?

Answer 1

You should to do like that:
function someFunction():void
CONFIG::DEBUGGING {
     SomeClassOnlyForDebugging.create();
without if.
