FC Module J1.5 - Scope - State parameter is not multi-valued

Hello, I had introduced a parameter to display unpublished items in the module by myself.

With the latest update that wasn't necessary anymore, how I found out, as the module now contains a method to pick a state for the item scope.

But, I'm at a loss now picking more than one state from the select list in the admin backend. I'm really scratching my head, how can one select more than one option in a Joomla admin param type "list" field?

The corresponding method in the helper file checks for an array.

It's J 1.5 and I'm on a Mac. What am I missing here?

Yes you are right, in J1.5 the Joomla parameter can not multi-valued,

i have created a custom field so that it is multi-valued, (will be in next public package):

here is the element file (you can place in element folder of the module):
the NEW fcitemstate.php form element r1498

and
here is the update module xml file to replace the existing one:
FLEXIcontent module XML file r1497

Thank you once more for your amazing work!
