In case you happen to live under a rock, I wanted to remind everyone that ColdFusion Developer Week starts in a couple of days.
What's that? You don't know what ColdFusion Developer Week is? Well, its a FREE week's worth of ColdFusion training from some of the best ColdFusion peeps around (did you see the list of speakers?)
Well, now you know what it is. So, go register. Now. And I better see you in my session. If not...well....I might cry.

As I mentioned here, CFCHART allows us point to an external file for the JSON configuration string, however, this file needs to be a plain text file - we cannot point to a ColdFusion file to generate the JSON configuration for us. Thanx to some help from Ray Camden, I figured out a way to 'trick' CFCHART into doing just that. I will admit, it is a bit of a kludge, but it works...and it works nicely.[More]

I thought I would take a break for talking about charting (but I will get back to it soon) to talk about some more 'small' enhancements to ColdFusion 10 that will make out lives just a tad bit easier.[More]

Here is a cool feature of the new charting in ColdFusion 10. As I have made mention of, the charting engine is using ZingChart 'under the hood' to generate the charts. ZingChart relies on a JSON string for its configuration - everything from what type of chart, to the data contained in a series, to the styling of the chart. When we use CFCHART, ColdFusion generates this JSON string for us. However, there is a way for us to tell ColdFusion what that JSON string should be.[More]

I have become quite enamored with the new charting engine in ColdFusion 10. However, there are some things that I don't love about them - its not that I hate or dislike them, I just think they can be better. One such thing is the default styling of the tooltips.[More]

One thing I have not played around with in recent versions of ColdFusion was cfchart . I simply have not had a need to do so. During lunch today, I was working on something that I hope to incorporate into one of my cf.Objective() presentations that required me to use the new charting engine in ColdFusion 10.
I do not want to give too much away - just in case it winds up falling flat - but here is a sample graph with which I was working.

To continue my 'series' of posts about new features that may get over looked, I wanted to point out 2 pretty cool changes to the ColdFusion Administrator.[More]

Raise you hand if you ever had a need to reset the CF Administrator password - because you forgot it or took over a system where no one knows the password. If you are a ColdFusion developer and you do not have your hand raised...you are lying.
It's happened to all of us at some point in time, especially on systems where we rarely need to access the Administrator. By know you probably also know that there is a way to do this that involves editing some configuration files and restarting ColdFusion. But ColdFusion 10 now offers us a new, and much easier, way to reset the password.[More]

OK, here is a ColdFusion 10 feature that I like. I will admit, its not difficult to mimic this behavior, but its cool none-the-less.
We should all be aware of the fact that when you submit a form to ColdFusion for processing, and the form contains multiple form fields with the same name (a list of checkboxes, for example) that these values will be available to us as a comma-delimited list in the FORM scope. Typically, I wind up changing this value to an array as I find it easier to work with arrays.[More]

I am a little late on announcing this, but I, once again, have the honor of once again speaking at cf.Objective().

On top of some of the 'big ticket' items in ColdFusion 10, there are also a lot of small langauge enhancements that will make it even easier to use ColdFusion. One such example is using for-in syntax in queries.[More]

Here is another neat new feature of ColdFusion 10 - Implicit CFC constructor. We can now set CFC properties when instantiating the CFC. This can be done by passing in name/value pairs or a structure. For example, let's assume we have the following CFC.[code]
In the past we would need to do this:[code]
But now, we can simply do this[code]
Or, we can use this syntax.[code]

Here is a quickie, and one that will make a lot of people very happy. Here is the new default for 'Client Variable Storage'

One of my favorite new features in ColdFusion 10 is ORM Search. ORM Search is pretty much what it sounds like, its a way to be able to quickly and easily search data stored in your ORM objects.
NOTE: All the code samples found in this post are from the sample code which you can get here. The code utilizes the 'cfbookclub' database and datasource that are installed when you install the demos[More]

I am working on a small personal project, using it, in part, as a learning experience and giving Test Driven Development a try. I decided at the beginning of the project to use ORM for my data persistence. Over the weekend I ran into an interesting problem that, when I finally found the reason, was one I should have picked up a lot sooner.
The project is a basic personal budgeting application. I decided to create my objects and their relationships and let ORM create the database tables, columns and foreign keys. This took a bit of time, but all the database items got created without issue.
One object, the Budget object, has two properties named Year and Month - to specify what month and year the budget represents. I also have an Account object that can have many Budgets. One thing I wanted to do was sort the Budget relationship by Year and Month so that when I called Account.getBudgets() the most recent budgets would be on top.
This should have been easy considering the orderby attribute of the ORM property. However, when I added the following:
orderby = "Year desc, Month desc"
I was getting an error from Hibernate stating that the order-by property could not be parsed.
Well, Google was not much help. I was able to find pages about this error message, but not anything related to ColdFusion. After clicking around a few links, it finally hit me what the issue was. Year and Month must be reserved words in MySQL.
It took one more Google search to figure out how to escape reserved words in MySQL. For those who do not know, it the ` character (its the key to the left of the 1 key). By changing the orderby to:
orderby = "`Year` desc, `Month` desc"
I was able to get past the error and have the Budgets sorted correctly. This should have been something I thought of sooner, but I think I was thrown off the scent by the fact that the columns were created without issue. That will not happen to me again.
I should note that this fix might not work in other database engines as they use different characters to 'escape reserved words. However, since, for now, this will not run on anything but MySQL, I can continue along writing my unit/integration tests
