Has anyone managed to get an order modifier to work on 2.4?

I must be missing somoething and would love to hear if anyone actually got one to work.
I am trying in my config

Order::set_modifiers(array("SimpleShippingModifier", "TaxModifier"));
SimpleShippingModifier::set_default_charge(10);
TaxModifier::set_for_country('NZ', 0.125, 'GST', 'exclusive');

But get nothing on frontend and database table remains empty???
Are they even getting added?

I am using the googlecode from jedateach

Hi wainui,

I've tested out SimpleShippingModifier, and TaxModifier in my (burnbright) development branch, and they appear to work fine. Note that you may need to clear the shopping cart contents after changing the modifiers list. Visiting mysite/shoppingcart/clear will do that for you.

thank you, thank you, thank you...

I cannot believe that I have wasted so much time to get this to work and simply clearing the shopping cart did the trick.

Thanks heaps, really appreciate it.

hi wainui

can you post a link to the trunk your using? I have tried the latest burnbright but it doesnt like the values you have posted. I get an error.

Cheers
