Wildcards :num and :any not working in my routes

[eluser]dwdaniell[/eluser]
I'm having this same problem - I want to have a URI that looks like this...

Code:

/example/value

... get mapped to my controller class Example, method call as lookup(value) - i.e. call the lookup method on my controller named "Example", passing it the argument "value".

I wrote my routing rule as:

Code:

$route['example/:any'] = "example/lookup";

... and that didn't work. But that's how it says to do it in the documentation... I tried a few other variations and they didn't work either. Any suggestions?
