Re: elemental2: Native maps with primitive types?
thanks that worked too.
It is Js.asAny(@DonotAutobox Object o) which performs an unchecked cast below.
Thanks for tips.

That is certainly an option but in some circumstances can lead to type
issues when casting. I tend to prefer using Any to do these sorts of
conversions. It is a little more verbose but it avoids any unexpected
casting problems. I don't have the code in front of me but I believe there
is a method like getAsAny("myprop") that works in this scenario

Re: elemental2: Native maps with primitive types?
yep that worked. thanks a bunch. I have seen the @DoNotAutoBox and I tried with Integer, Number, JsNumber. Note: I can put int in the JsPropertyMap but I cannot read it back. So I cast it to (double) and the then to (int). I believe that is because JavaScript does not have int type. thanks again.

Re: elemental2: Native maps with primitive types?
JsPropertyMap.set(key, value) is marked with @DoNotAutoBox, so I guess you should be able to use JsPropertyMap and set int, float, double into it without them being auto boxed. -- J. -- You received this message because you are subscribed to the Google Groups "GWT Users" group.
