ExtJS 2.* or ExtJS3.*

[mxu]

hello,

I mimic standalone app for a web app using ExtJS 2.* over a couple of year backs, . see the link
http://www.ncbi.nlm.nih.gov/projects...1&to=191000001
but unfortunately the codes broke when I linked to ExtJS3.* js libs.
I can stay with ExtJS2.2 for now but how long will ExtJS2.2 last ? the 2.2 will get update for new version of FF. IE, etc ?

thanks

No, the whole Ext 2.x branch is EOL.

Upgrading to 2.3 will give you Firefox 3 support, but I would really recommend upgrading to 3.x.

Did you read the Upgrading to Ext 3 thread?

tried to migrate to v3.* but the app totally broke at core js libs
js libs included in order as below are
...
<script type="text/javascript" src="/core/extjs/ext-3.2.1/adapter/ext/ext-base-debug.js"></script>
<script type="text/javascript" src="/core/extjs/ext-3.2.1/ext-all-debug.js"></script>
...

at the page initial loading,
Firebug stopped at var o = this.getConnectionObject(); for sync ajax call
complaining getConnectionObject() undefiend
when I commented out the sync ajax and Firebug stopped at Ext.Fly(ce), line#9808 at ext-all-debug.js
9806 if (this.contentEl){
9807 var ce = Ext.getDom(this.contentEl);
9808 Ext.fly(ce).removeClass(['x-hidden', 'x-hide-display']);
9809 contentTarget.appendChild(ce);
9810 }

are page loading different between V2.2 and v3.* ?

thanks

You want to make synchronous Ajax calls?

Are you using a user extension for that (e.g. ext-basex)? You will need to upgrade all extensions to Ext 3 compatible versions too.

yes, I need sync call for genome info to populate individual tracks.
I coded the page over two years and used many user modified/extension, it's ok to migrate to 2.3.0 but not 3.*.
for sure I am going to get a few more gray hair at migrating to 3.*, or Probably wait for ExtJS 4.* as long as
v2.3 works for current browsers.

anyhow EXtJS is the best JS widets for web app.
