Flex3 Corelib JSON issues

alexr — Thu, 27 Mar 2008 13:02:24 GMT

I am testing webscripts (JSON) on Alfresco Community 2.1I downloaded the ascorelib3 corelib90 (containing JSON funcionality) from http://code.google.com/p/as3corelib/ and configured it for Flexbuilder 3. Howeverfor some reason this corelib doesn't seem to work with Flex3?Does anybody have a corelib.

If you want to use Flex with Alfresco, you should start with the the small flex framework from the alfresco SVN ( head/root/modules/flex-sdk/framework) to provide login/logout/webscript infrastructure, and ACE ( head/root/modules/ace ) to provide an example of login/logout/search using the framework. Thats how I started.

I am pretty far along with both a Flex based Alfresco client and a Flex+AIR Alfresco client. I am using Flex 3.0, AIR 1.0, and the latest Alfresco 2.9.0C_dev via javascript webscripts. From google code: I didn't use corelib, I did use flexlib for tabs.

The alfresco flex-sdk works fine for the object result format of the flex mx.rpc.http.HTTPService. I had to change org.alfresco.framework.service.webscript.WebScriptService.as to work with the e4x result format of mx.rpc.http.HTTPService.

On as3corelib to decode JSON with text format from flex HTTPService
1. Noticed problem parsing "<" in the error stack
2. latest build (.90) of as3corelib is old (March 19, 2007)
3. you could try slightly newer code (last change may 27, 2007) in src/com/adobe/serialization/json/*.* via
http://code.google.com/p/as3corelib/source/browse
or svn checkout http://as3corelib.googlecode.com/svn/trunk/ as3corelib-read-only
4. noticed some json encode/decode issues at http://code.google.com/p/as3corelib/issues/list

P.S.
if using alfresco flex-sdk with HTTPService with non object result format, a quick workaround in
src/org/alfresco/framework/service/webscript/WebScriptService.as onResultEvent() is to change
from:   if (event.result.response != null &&
to:       if (this.resultFormat == "object" &&
               event.result.response != null &&
(more changes would be needed to have status code checking for other formats)

New: Forgot to mention that in each of my ActionScript service classes set webScript.resultFormat ="e4x";   (where webScript is instance of org.alfresco.framework.service.webscript.WebScriptService, WebScriptService extends flex HTTPService)

Thank you Steve,

The webservice URL i tested was broken (server down). I tested another json webservice (Yahoo) and my mxml application worked. So Flexbuilder
and the corelib seems to be configured ok.
I have however posted a new question about json and the folder.get webscript in this forum branch.

Kind regards,

Alex
