Pre-3.0 API and Latest Chrome

AllenAnselmo

Hey all,

Not sure how much this affects any of you, but I thought I'd post it either way to get the information out there. It seems that the latest version of Chrome (29.0.1547.57 m) that came out Tuesday or so, has made some change which causes pages with older ESRI Javascript API versions (pre-3.0) to fail to load due to some sort of errors being triggered in the contenPane loading code of dojo it seems.

It doesn't seem to be affecting our pages that are more up to date (3.5+) but we have some older ones in production which lock up entirely on load in Chrome now and weren't doing so last week, whereas they load fine in the latest Firefox and IE browsers.

Anyone else running into this situation or even have any older pages in production that haven't gotten upgraded?

If so, be sure to put in a bug report to Chrome through the Menu > Tools > Report an Issue tool, since the more they get in, the more likely they are to fix whatever they broke so abruptly.

Here's a very simple workaround: before your script tag that references the JS API, include this in a script tag:

// fix for https://bugs.dojotoolkit.org/ticket/17400
!document.firstChild.children && (document.firstChild.children = true);

Ideal place would be where you define dojoConfig.

Here's a working example: http://jsbin.com/OmUjAmI/1

zhifengtang,

IE10 is not supported at version 2.1 of the API. If you need to support IE10 you'll have to upgrade to version 3.4 or greater.

We are using JSAPI v2.1 and both IE 10 and Chrome have issues.

Thanks everybody. We're testing fixes.

We do not plan to modify what's currently hosted on serverapi.arcgisonline.com but will likely post patched versions of the API on js.arcgis.com. Applying the fix will require you to change the URL your app uses for the JS API. For instance, if you use 2.8 from serverapi:

<script src="http://serverapi.arcgisonline.com/jsapi/arcgis/2.8/"></script>

To get a patched equivalent, once we upload patched versions, you'll update your app to use:

<script src="http://js.arcgis.com/2.8/"></script>

I'll post here when we're further along in this process and/or if anything changes. Thanks for being patient.

We are using 2.8. Thanks for looking into this.

We are experiencing an issue with Chrome v29+ and version 2.8 of ArcGIS JSAPI

The solutions I've seen online seem to reference the query.js file whereas the JSAPI doesn't load that file but I see a similar pattern in init.js (but since it is minified I'm not sure where the actual problem code is).

Would appreciate any fixes from ESRI. We plan to upgrade the JSAPI at some point but a temporary fix would be a lifesaver.

UPDATE: The fix that svignara posted above allows the map to load, but calling getChildren() on our BorderContainer only returns 1 child element when there should be two, so it is still broken

Various versions from 2.4 - 2.8.

We're looking into the best way to fix this.

Can everyone in this thread post the version of the JS API they're using?

Using version 2.6.

Thanks.

I was able to make a quick fix to this issue with dojo and chrome version 29 using the suggestion given in this forum: http://productforums.google.com/forum/#!topic/chrome/wPXjwJ_Kf3M

Steps I took:

-Download just the query.js from dojo 1.6 toolkit: http://download.dojotoolkit.org/release-1.6.0/dojo-release-1.6.0/dojo/_base/query.js

-Remove the condition that checks if resource has already been loaded (dojo._hasResource["dojo._base.query"])

-On line 499, edit it so for chrome v29, _noNES is always true:

var _noNES = (navigator.userAgent.indexOf('Chrome/29') >= 0) ? true : (typeof getDoc().firstChild.nextElementSibling == "undefined");

-In your HTML, to make it efficient only load this script when the userAgent is chrome v29. So other browsers do not load this script unnecessarily:

<script type="text/javascript">
            if (navigator.userAgent.indexOf('Chrome/29') >= 0){
                document.write('<script type="text/javascript" src="/path/to/query.js"><\/script>');
            }
</script>

This is still inefficient, considering you have to load the query.js file to override ESRI's - but this fix should keep things stable till the problem gets fixed.

I really hope this gets fixed by esri. I don't feel like going back and rewriting code when there is a fix available.

AaronDrake

Good find.

Hopefully Esri will take care of this...

EricHanson

A Dojo blog about the issue.

Anyone know if ESRI will update its pre-3.0 apis with this fix?

It appears to be causing issues on a number of applications.

AaronDrake

I have written a web mapping application using JSAPI 2.1. This application has been in service since 2010, and has had no issues when viewed in Chrome. That was until Chrome updated to version 29.0.1547.57.

My users are all receiving an error (via Developer Console):
Uncaught TypeError: Object #<Text> has no method 'getAttribute' from FormSelectWidget.xd.js 8

I can confirm that it is something with the latest Chrome version, as I rolled one of our machines back to version 28.0.1500.95, and the application worked fine.

I am not sure what changes were made from version 28 to 29, but something is definitely affecting the application in an adverse way.

Also, it should be noted that the application works fine in IE9, IE10, Opera (latest), Firefox, etc.
