[Qgis-developer] Processing - R script parameters error

[matteo]

Hi all,

keeping on exploring the Processing - R script capabilities, there are
some input parameters that I'm not able to use.

For example there is the multiple field option, as described in the code:

In a script you can use it with
##Fields=[optional] multiple field [number|string] Parentinput

but if I use it in a script like

##layer=vector
##fields=multiple field layer

I get this error:

NameError
global name 'QtCore' is not defined


am I missing something?

Thanks

Matteo
