Controller 1.6 on 1.7 ?

[Julexe]

Hi, I finally finished my first modul on 1.6 and it worked well, but I have a problem when I tried it on 1.7 version.
I used a hook ('DisplayCustomerAccount') to add a button in the my account space of the front office, but when I clicked on my button it tell me that there no page found (error 404).

 

I tried to copy the other button code but it didn't work, so for example the order slip button call :
 href="{$urls.pages.order_slip} and in SEO the link is order-slip. So he changed " - " to " _ ".
 

My module use module-eccustomerfiles-documents so I write :

href="{$urls.pages.ec-customerfiles-documents

 

But it still failed.

 

Someone can help me please ?

 

PS : On 1.6 the hook used "getPageLink" and when I use it for the 1.7 I got an error 500.
