How do you set selectedItems before opening multi-choice dialog?

[ghost]

I've seen this "public" setter in the class, but it's commented as private and not working, so I gess that's for the native code to use, but why can't we set this ? It seem to me a pretty basic and necessary feature !?!
Thanks.

In the NativeListDialog.as in the row 323 instead of "_selectedValues[k]==true;" must be "_selectedValues[k]=true;", and in the row 384 instead of "_selectedValues[j] = true;" must be "_selectedValues[val] = true;". Can anybody recompile it?
