Dylan, I usually pass "this()" in to an external method to get a handle on acquisition from an external method. e.g.: <dtml-call "emMyExternalMethod(this())"> def myExternalMethod(context): if context.folder.attribute: do something else: do something else this() generally refers to the folder containing the dtml method. in the external method, you can use acquisition through this object.

I want to find out if a callable object exists from a folder object using acquisition. ie if I call folder.method() it will be guaranteed to work.
