Re: jsinterop: converting a jre collection to a jsArray

That question came up already in the forum or in GWT-Contrib (try to search the archive), and I seem to recall that Goktug said you could cast @JsType(isNative=true) objects to/from JavaScriptObject, so you could use JsArray (and JsonUtils.safeEval). I think you can also cast to/from an array of @JsType(isNative=true), so if you don't need to alter the size of the JS array you can then use the bracket operators on a Java array (and cast from/to a JavaScriptObject).

This is only out of memory, please double check from the forum archives.

Hi again,

I am trying to convert a jre collection or build a jsArray with a isNative=true type.

Unfortunately this is not possible because JsArray requires JavascriptObject which is invcompatible (complie time error) with native classes.

Any ideas?

I looked on deep dive jsinterop from Ray Cromwell and it says that there is not a clean way for jsinterop1 to align collections. Ok I get that - but there must be a way even if not the nicest/cleanest one.

Otherwise looks like I have to create my own @jsinteroped MyJsArray which looks wrong.
