Short News: 4th of July

* I'm finally back from all my traveling.
* Cannes was great; we got shortlisted for the Guinness Hands microsite
* CFUnited was great; gave the 8h flex class to about 20 students. IMHO it went pretty well; tons of examples, started slow and then got well advanced. Then I gave two sessions, one on Factories and one of Flex and Ajax. I liked the factories one, but I wasn't fully satistied with the Flex/Ajax one.
* Happy 4th of July.
* I ordered my new MacBook Pro yesterday. It may take a few weeks (so they said), because I chose to upgrade the HD to a 7200RPM one.
* I will be speaking at Max on ColdFusion (CFMX8) Powered Ajax
* I'm officially hooked into ANT now and will release some scripts soon.

jQuery v1.1.3.1 is now out. We should look at upgrading AjaxCFC accordingly.

Hey Rob,

I enjoyed the Flex class at CFUnited last week. Do you think you can post the PowerPoint and code examples? There is still one that I haven't figured out yet

Thanks,

Brian Caufield

Hello, I like ajaxCFC very much. We are using the earlier ajaxCFC version. I run into some Memory Leak Problems with IE with my projekt. After removing all js handling code I get still a stange rise of memory running just simple ajaxCFC calls. Test case: returning an array[10][50] as r with plain text, for each array item (in my case, to bulid a table). Return function eg. doNothing. function doNothing(r){ r=null;}. A timeout function to repeat this call every 3 second without reloading the page. Memory rises up and up in IE. FF is more ore less stable. (Possible problems for this - seen on other Ajax framework pages: onreadystate or the body.appendChild(...) in engine.js.

Is there a known issue about that and will the new jQuery version have the same behaviour/same engine?

As I was not able to post something at the ajaxCFC projekt page, therefore I post my input her, hoping SOMEONE could verify my input and add it to the next version of ajaxCFC - if it makes sence...

function "returnAjax" in file ajax.cfc

#result#
DWREngine._handleResponse('#id#', _#id#);
_#id#=null; // added by me

The last line sets new WDDXRecordset() to null after processing. Otherwise your memory grows up and up by each ajax request, when not reloading the page !
