[Flow] Form ViewHelper for property that is an array of strings

[Christian Loock]

Hi again,

another little problem I encountered.

When I have a widget ViewHelper inside a f:form, form fields inside this 
viewHelper, won't have the correct fieldNames, since they dont seem to 
be aware of the form object of the form that is surrounding the widget. 
I assume this has to do with the fact, that a widget is renderen in it's 
own subrequest, which probably isn't aware of the fact, that there is a 
form surrounding the widget. Is there a way to make form elements inside 
the widget aware of a surrounding form?

Cheers,

Christian
