RE: "including" functions
Oblio, As you have found out, CFC creation paths are relative to the CALLING template, not the compiled-post-include-rendering-and-all-that-jazz object. Therefore, the CFC path is relative the included template, not the CFC. One option to over come this is to have a CreateCFC() method in an included template that is in a higher directory: Then, in each of your other include functions, you can assume that THIS.CreateCFC() is a valid method of the current component. Then, instead of calling CreateObject() with your path, call THIS.CreateCFC( "component_name" ) and you can handle all of the path stuff in the CreateCFC() method which will be higher than the current directory. Make sense? Here is a blog entry on the proof of concept (but not using CFCs exactly): http://www.bennadel.com/index.cfm?dax=blog:348.view ..

Re: "including" functions
You can inject one object (CFC) into another then the functions and properties of the injected cfc would be available to the one you are injecting it into. For example you have an argument, possibly in the init function, that accepts the name of the CFC as the type of the argument. >I'd like to be able to create one file per function and "include" them >when the component is instantiated. > >You could use the "extends" property of the CFC or you could modify the >base CFC, but those may not be what you are looking for. > >For a more mix-and-match approach, I think you may want to look into the >"mixins" concept.

RE: "including" functions
-Original Message- From: Ian Skinner [mailto:[EMAIL PROTECTED] You could use the "extends" property of the CFC or you could modify the base CFC, but those may not be what you are looking for. Nope. I think I'd end up with a serial chain of CFCs, rather than a library of functions. For a more mix-and-match approach, I think you may want to look into the "mixins" concept.
