Subject [jira] [Commented] (CB-588) Cordova breaks Events for GWT Apps
Date Fri, 27 Apr 2012 17:38:49 GMT

    [ https://issues.apache.org/jira/browse/CB-588?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13263824#comment-13263824

Filip Maj commented on CB-588:
------------------------------

Interestingggg.

I think the {{typeof}} method is the way to go instead of checking the {{object.toString}}
value.

As one example, in the old BlackBerry 5 browser, if you did a {{toString}} on core native
objects as Function or Array, you would "[object]" (presumably that browser didn't track the
prototype "class" name). Probably a bad example as it's a crappy old browser but I feel that
checking string values from toString is more brittle than checking typeof.

I'll make the change and run through some basic deviceready tests on a couple devices to make
sure nothing breaks.

> GWT Apps (Google Web Toolkit) use several different mechanism for loading their compiled
code. 
> Most of the times the code is loaded into a hidden iframe for separation with the main
page.
> In the past this was no issue, but it seems that the transition to requireJS introduced
some problems.
> For some reason cordova is unable to call functions that are dynamically defined in that
iframe.
> I had a hard time boiling this down because there is a lot of code generated by GWT.
I will attach a simple demo project which consists of the generated boot script, which will
load a html file (which will contain the app code) into a hidden iframe.
> The only thing the GWT App does is to register for the resume event, the callback is
added to the resume channel correctly. The problem is when the channel fires.
> The fire method of Channel fails to recognize the gwt function as instances of Functions.
Trying to call it manually results in no events firing at all....
> I`ll be happy to provide more information as needed, this one has already taken me quite
a while.
