To go through an array one can use:

cfloop array=#MyArray# index="myIndex"


Scoping
Sometimes you need to catch events from an itemRenderer, but most likely you'll get "call to a possible undefined function" error. That is because the itemRenderer has a different scope than other objects on the page and does not see any of the page's code. Instead of using this:

event="{eventHandler();}"

you should use the following:

event="{outerDocument.eventHandler();}"
