ColdFusion Ajax and ExtJs Presentation Update
I've been asked to present to the KCDevCore on ColdFusion 9 Ajax and ExtJs. This will be an updated version of my ColdFusion Ajax presentation, with new content to cover the updates and new components presented in ColdFusion 9 and ExtJs 3.0. By request, I'm going to try to keep the slides to a minimum and get down to some code.
That presentation will be next Tuesday, September 29th, at 7 PM CDT, and will be available via the KCDevCore Adobe Connect.
For those who don't know (where have you been?), ColdFusion 9 is now in public beta on Adobe Labs.

First of all as a Marylander with a house in Ocean City, I am very impressed that you worked at Seacrets. Sorry I did not know this earlier. I would have bought you a/several beer(s).
I have been following your and Dan Vega's posts on CF and Ext over the last year. I read your posts on how some Ext components no longer work the same with CF9 and Ext 3.0. Long story short, you both convinced me to learn Ext. Needless to say, I purchased your book - Learning Ext Js and I purchased Ext 3.0. Both from Packit.
I have made it through Chapter 3 of your book and got to the 9_forms_combobox_server.cfm example. I did not want to learn or load php so I have been converting all the php modules to cfm and where appropriate, cfc , and surprisingly everything has been working fine.
I am now trying to query a database with Ext and am trying 2 different versions of the genres.cfc. One using action script to populate the datastore and the other with a datbase query of the genres table I created. The query has a return type of json.
Well neither method worked. Can you suggest how to debug this in firebug ( yes I need to learn this as well) or provide an example of querying the genres table.
thanks,
Bud
Yeah, last night we were having some drinks with some friends who followed us out here to Nashville. My wife (and our friends) all grew up in Princess Anne. I was talking about how, sometimes, I really miss Seacrets. It was a lot of work, with exceedingly long hours, but fun most of the time.
Shea wrote Chapter 3 of the book, I wrote Chapter 12 on. It really shouldn't be overly difficult to translate his work to CF, though you will want to get the latest version of CFQueryReader out of RIAForge (http://cfqueryreader.riaforge.org). CFQueryReader replaces the CFJsonReader used in the examples of Chapter 12, and the unpacked source file should be fairly well commented. Drop me a line, through the contact link at the bottom of this page, if you keep hitting walls.
Have you made the source available for this presentation? I was watching it tonight and saw some interesting things in PresoBuilder/admin/author/index.cfm, at line 65, which might solve a problem I've been having with respect to getting finer-grained control over the column model for a CFGrid.
Thanks Steve.
