GWT and Oracle

[Eric Nissan]

Hey just curious, does Oracle contribute to GWT at all?  I know they are in 
a battle with Google over Java (android), but one would think they could 
put that aside and contribute as GWT really does encourage Java usage.

Re: jsinterop

[Eric Nissan]

I don't know if this is the best way, but I got it to work by making my own 
implementation of  jsArray.

I changed the generic definition from 

public class JsArray extends JavaScriptObject {


to 

public class JsArray extends JavaScriptObject

which worked with my jsinterop interface.

the problem I see is that although the documentation says an interface 
market JsType will be treated as a JavaScriptObject when casting, that does 
not help for using it in place of a generic.

I don't know what will blow up from this, but it seems to work for me.  If 
there is a better way to do this, I am all ears :)

Thanks,
Eric

Re: jsinterop

[Eric Nissan]

I tried that also, but

Data[] thing = JsonUtils.safeEval(response.getText()).cast();

does not compile as Data[] is not a JavaScriptObject

Re: jsinterop

Thanks a ton!  that worked.
followup, how do I set a List?
I tried to use JsArray but that requires a JavaScriptObject, which Data is 
not.

jsinterop

[Eric Nissan]

sorry if this has been answered, I just started using jsinterop in gwt 2.8. 
 What is the recommended way populate data into a jsinterop javascript 
object from my server.  Assuming I have Json, do we still use OverlayTypes? 
 or is there a better way to do it?

Always appreciative,
Eric

GWT 3.0 Question

[Eric Nissan]

I keep reading that GWT 3.0 will not have uibinder or widgets.  I don't 
understand what that means for future versions Wwill all my existing code 
that uses uiBinder, and all my widgets cease to work with GWT 3.0?  Is 
there anything I can watch/read that explains what we should expect in the 
future?

JSNI Question

[Eric Nissan]

I am using JSNI to reference a javascript library.  My initial call is 
fine, but then somewhere down they chain I get a null pointer inside the 
javascript library.

I am referencing the library like this

$wnd.TradingView.widget({});

which is a valid reference.  

This then seems to load in other javascript files.  the object it loads are 
not referenced as $wnd (because that is a GWT thing), and I eventually get 
a "cannot read property 'init' of undefined".

My question is, could this be causing my problems?  
for example I am getting this error on this call.  Is this because it is 
not prefaced with $wnd?
$.i18n.init({})
