Tapestry 5.1 and multivalued parameters

I'm trying to use a form with multivalued parameters in tapestry but I'm not sure if it supports this kind of feature or how it does. I searched the web for some clues but couldn't find any decent information about multi parameters request using this framework.

The problem is I'm generating a grid and in one cell I'm using a TextField which is supposed to be multivalued, this way:

My page's java component:

Trying to set the newSpecialValue as a Collection<String> (something like WebWork OGNL type conversion) gave me an exception: Render queue error in BeginRender[Index:textfield]: Parameter 'translate' of component Index:textfield is bound to null. This parameter is not allowed to be null.

If anyone has any clue or a link with information I'd be very glad.

The link was provided by Otho from tapestry users list. Very good one.
