• Learning ColdFusion 9: Implicit Struct And Array Usage

  Posted on Jul 13, 2009 at 3:48 PM

  Definitely both funky bugs. Just to clarify too, I think we should state that these relate to the ColdFusion 9 *Public Beta* - hopefully they won't be present in the final release of ColdFusion 9 ;)... read more »

• Create A Running Average Without Storing Individual Values

  Posted on Jul 3, 2009 at 2:57 PM

  This is how I always want to implement average rating kind of features (with just two fields) but I usually have the requirement for ensuring a user can only add a rating once, hence resorting to the usual "store each value with a userID in an intermediate table" approach :P... read more »

• ColdFusion 8's OnMissingTemplate() - So Close To Being Good

  Posted on Jul 1, 2009 at 5:54 PM

  The most obvious use for onMissingTemplate() is when you actually want to handle a request for a .cfm file that doesn't exist. ColdFusion processes all .cfm requests and so in that case it would leave you with a ColdFusion template not found error page rather than showing the web servers 404 Not... read more »

• ColdFusion Tag Parameters Can Be Included In Separate Files (Thanks Mark Drew!)

  Posted on Jun 17, 2009 at 12:10 PM

  I've also done this with nested custom tags in the ColdExt project, with a bit of trickery looking through the list of parent tags you can safely ignore standard CF tags (including cfinclude) and only pass data back to a parent tag that belongs to your own library (using cfassociate), even when t... read more »

• CFM Templates And Remote CFCs - They're All Just ColdFusion Page Requests

  Posted on May 18, 2009 at 11:05 AM

  Maybe people are just impressed that CF8 lets you specify returnformat="plain" on remote method calls to let you get back a plain text response, since CFMX7 and before doesn't support returnformat and always wraps the response in a WDDX packet. A few weeks ago I was working on a CFMX7 serv... read more »

• Ask Ben: Executing ColdFusion Custom Tag Code If First Run Only

  Posted on May 4, 2009 at 7:05 PM

  @Ben: Ahh, I see what you mean about the calling context and using something like cfthread, nice trick :) Perhaps you could also pass a reference to the namespace/scope to the custom tag rather than passing the namespace as a string? e.g. <cf_demo2> or... <cf_demo2... read more »

• Ask Ben: Executing ColdFusion Custom Tag Code If First Run Only

  Posted on May 4, 2009 at 4:37 PM

  I do a similar thing in ColdExt to keep track of loaded JS resources, though I just use the request scope directly, as you say you would traditionally do. Is the combination of the caller scope + StructKeyExists() letting you do something that wouldn't normally be possible, or is it just letting... read more »

• Paraming ColdFusion XML Documents With CFParam

  Posted on May 4, 2009 at 10:07 AM

  Ben beat me to it! I tested it as well, and you can just use the array notation. The XML document would need a <girls> root node though of course :)... read more »

• Randomly Executing Only One ColdFusion Custom Tag Child

  Posted on Apr 22, 2009 at 12:18 PM

  Custom tags rock :) I think complex nested custom tags are one of the most under used features of CF. The cfassociate tag, GetBaseTagData() and GetBaseTagList() can do some pretty awesome stuff and until I wrote ColdExt I had no idea just how powerful a few custom tags could be. The cfexit/... read more »

• ColdFusion Components As Data Types - Help Or Hindrance?

  Posted on Apr 9, 2009 at 3:24 PM

  I think one reason enough to not use CFC's as data types is the lack of performance when it comes to object instantiation. Usually a data type is a simpler construct than a full blown class (which is pretty much what a CFC is). For example in C/C++ the "struct" keyword is what you use to de... read more »

• Overriding ColdFusion's ArgumentCollection And An Extremely Weird Behavior!

  Posted on Dec 5, 2008 at 1:39 PM

  @Ben: I think the confusion is the second guessing of how argumentCollection should work and the assumption that it is "passed into" a function as a struct... In my code, the cfset inside the function modifies the original struct, it can't. The only modification that is occuring is caused b... read more »
