Multi Value. What does it look like?

This is what I had, but it doesnt seem to pull back any data.

<collection>
  <object>
    <fields>
    <field> <value>RoleName1</value></field>

    <field> <value>RoleName2</value></field>
    </fields>
  </object>

</collection>

<values><value>RoleName1</value><value>RoleName2</value></values>

Is what actually works.    The only problem left is how to convert a CheckBoxList into that?

Im trying to achieve the same thing in logic on a SmartForm. I have tried the above XML but it does not work for me, it brings back nothing everytime?

I’m using K2 Five 5.3 FP23, has something changed?
