Filling date gaps in a report

I needed a way to push a bunch of blank dates into a query for a cfchart to ensure I didn't have any gaps in my date coverage. This article did the trick...

AjaxOnLoad and cfhtmlhead

I had an odd issue today where I was using AjaxOnLoad to run a javascript, and I was getting an error that the function was not defined. The function and the ColdFusion.Event.registerOnLoad even were both getting added to the page. I could create an anchor tag on the page with an onclick and it would run the code fine, so I was perplexed as to why it was telling me that the function wasn't defined. See if you can spot the problem. Turns out that CF is simply adding content to the head of the document as you call the CF code. This means that with the above code snippet, the registerOnLoad script was getting called before the other function in the code. Changing my CF to this fixed the issue: I'm not used to thinking that hard about where I stick my cfhtmlhead tags. Guess I better pay closer attention next time.

onMissingMethod Issue Cleared Up

At LandsofAmerica I've been making extensive use of the onMissingMethod() functionality of CF8 to provide implicit getters and setters. This has worked fantastically well, and I'm never going back to explicitly declaring these unless I have to :). But one problem I've had was with using my implicit getters and setters inside my objects. It just didn't work... My onMissingMethod() functionality is wrapped up in a base decorator object that all of my base objects extend. It looks like this: So within my objects, if I called getSomeValue(), I would get an error that method didn't exist (duh, that's why I have onMissingMethod()). For the life of me I couldn't figure out a way around it, so I just started calling get("SomeValue") while I was inside an object. This was workable, though not necessarily ideal. It means that if I refactor a particular method to make it explicit (by creating a getSomeValue method), then I would need to go through my object and replace all of the get("somevalue") calls with getSomeValue(). Well Ben Nadel just made a post on his blog, Comprehensive ColdFusion Component OnMissingMethod() Testing that solves the problem... When calling an objects internal methods, if you always THIS scope them, then onMissingMethod will fire like it's supposed to. Thanks Ben, now I have to go through and do all of those find/replaces ;-)
