AIR : Ext.Ajax.request not working

[ghyster]

I'm trying to build an AIR app to access remote data but Ext.ajax.request fails :

"Error: Adobe AIR runtime security violation for JavaScript code in the application security sandbox (eval)"

I looked into the ExtDocs AIR app and saw that there was a call to http://extjs.com/playpen/api.php when searching in the API (using an HttpProxy)

How does it work ?

you'll have to use scriptag proxy to do cross-domain requests.

[ghyster]

cross-domain requests are allowed in AIR apps (eg the ExtDocs app)

the eval function is not allowed and I wondered how Jack make ajax requests work in the ExtDocs app

[jay@moduscreate.com]

crap, you're right. :) I have little experience with air. 8-|

Does the new version of Ext get around this?!

You might be interested in this blog series I did which outlines how to use Ext in an AIR app. It all comes down to Adobe's security model. Here's the link, it's a five part series but the first part may be all you need as it contains links at the bottom to Adobe docs:

thanks bricemason for your article,

however I found that the ajax request worked well, the problem was I used Ext.decode to decode the response, the security issue was there

How did you work around the decode issue? I also want get the response as JSON and actually need to decode it.

Eval with a JSON string is allowed in air 1.0.

if you need more "eval" set up the browser sandbox by using an iframe

[RobSmith]

Thanks for reply, I only need JSON evaluation.

Well, that should work... since beta 3 ;)
