evaluate() is still a cry for help
Line 169 of Entity.cfc from Blade 0.62 (an ORM example):
evaluate('this.set#local.property#(arguments.properties[local.property])');
Even with all the CF9 conventions this is still the only way to do it?
Upgraded to Blade 0.62
My install of the Blade demo has survived an upgrade http://www.markireland.com.au/stepbystepblog/step4/index.cfm
moved to CF 9.0.1
This is just a test post to see if the move to CF 9.0.1 is all good.
I am checking out cfScaffold and Blade both examples using ORM.
ColdFusion applications do not really exist
This is a little counter-intuitive so I am quoting Ben Nadel here:
"ColdFusion applications do not really exist. At least not in the way you might think of a traditional desktop application that has a running process. ColdFusion applications do not have a constant process. Instead, they have memory scopes. Each application has its own name which ties it to a chunk of memory somewhere. Every time you define an application through the Application.cfc (or CFApplication), what you are really doing it associating the current page request to the chunk of memory that is associated with that application name.
When you start to look at ColdFusion applications this way, it becomes a little more clear why you cannot explicitly kill an application or a session; there simply is nothing to kill. An application doesn't run unless you have a running page that requests to be associated with it."
So how is a count of sessions calculated? Is it simply not gone until 8 hours (the default setting in the servers xml) has passed? Add it, wait 8 hours and subtract it?

cfImage and Jcrop and RaphaelJS and ckeditor
Here is a nice use of the deepliquid Jcrop jQuery plugin by Matt Gifford
If you like this check out RaphaelJS
The fckEditor is now a jQuery plugin called ckeditor.
Stop using returnType="query" with ajax and jQuery
Would it be worth it to stop using returnType="query" with ajax and jQuery?
I could try to standardise the way the data returned uses JSON. I would prefer a structure that always has a key that I can use as an index.
Apache Axis 1.4. and Adobe Coldfusion 9
On the cfAussie list Mr Buzzy said he was able to upgrade to Apache Axis 1.4 for use with Adobe Coldfusion 9.
He warned that some official update releases will roll it back to Axis 1.2
Cant Adobe release some advice on this?
Managing live tracker development on the Web
Ben Koski posted Behind the scenes of a live World Cup and it reminded me of all the times I have advised people to avoid having one of every different web server technology in production.
I see now that this advice is not good since this application uses Ruby, Ruby On Rails, Flash, PHP, XML feeds, fancy CSS and Amazon S3 with reporters watching logs with their Apple Macs.
It makes my BHPBilliton ScoreCard app look lame.
