Hi

I also have that problem such that when i set my HelperPath to my view helpers ZF for some reason doesnt render the output as expected. Am not sure if it is a path resolving issue - I did everything but nothing worked!!

But when i moved the helpers to the Zend>View>Helper of the Zend component folder they work. - though not ideal this seems to be the only working option for me. So you might be having the problem of path resolves.(adding your helper folder to an include folder to apache also didnt work for me).

Try putting them in that folder and see if it works. Let me know though
