This problem is caused by evaluation of <in/out-var>s. AS uses
internally Velocity/WebMacro as engine for expressions and
conditions. Until this is rewritten (scheduled for AS 0.96),
there is a workaround: define a type handler for these cases,
something like:

<type-handlers>
   <type-handler source-type=3D"java.lang.Integer"=20
                 target-type=3D"long" class=3D"Dummy"/>
</type-handlers>

public class Dummy implements SimpleTypeHandler {
   public Object convert(Context context, Object o) {return o;}
}

It would be necessary to add all combinations of THs for
conversions from wrapper classes to primitive types, like:=20
Integer -> long, Short -> int, Short -> long etc., which
could be done for AS 0.94.1 :)
