I'm still wondering about this, since it sounds like its not working correctly here. What is the scale of pages in your site using the template 'cool-page' and what auto join fields does that template have? I'm just trying to find out as much info as possible to be able to reproduce it.

I think i know the issue... kinda wild tho - not sure if it's a buffering limit or what... as i'm on my localhost.. (shrug).
Its when I do var_dump of the 'children' objects, etc.. any time i seem/tend to dump that to the screen, then i'm seizing up the system, and it gives me the 'white-wall-of-doom!'

When i remove it, ir do the var_dump on anything else (obviously smaller than the children object array, etc...) it's all fine.

p.s. er so it seems

Thanks...
(high-five with all of you for helping me with it!)

The above was saved to a HelperAttributes.module and placed into my site/modules folder

IF ANYTHING - someone will find this helpful in starting their own module (possibly?)

I only have about 100 pages (nothing to sneeze at...).

... This is consistent to how you'd usually refer to a class::method in documentation, outside of a specific instance. If you only wanted to hook one instance then the syntax would be $objectToHook->addHook('method', $myObject, 'myMethod'); and $myObject is most commonly $this.

Got it now. The "::" abstract call was throwing me off a bit was all.

Thanks for the very thorough explanation. Lovin' it.
