@gianarb Is it possible to get this merged soon?

This fix broke something with people that are using ZF2?

I think yes but I am not sure.. Anyone can try with ZF2? :)

@exptom @lorenzoferrarajr maybe you can help us..

Thanks a lot

@gianarb There shouldn't be a problem with ZF2. The service names are case-insensitive in ZF2 but they are case sensitive in ZF3.

As you can see the view helper is registered with the uppercase 'Z': https://github.com/zendframework/ZendDeveloperTools/blob/master/src/Module.php#L132 so this PR is actually changing the invocation to the correct way of calling it. ZF2 will continue to work with it written with either a lower or upper case Z.
