Should formatter keep a reference to the raw column data?

Hello, I've been using the datagrid for a couple of months and i have deal with custom formatters and conditional actions.

Currently if i need to format a status column (integer), i use a custom formatter called LabelFormatter which displays the status column to a human readable status ie:

1 => '<label class="open">OPEN</label>'
2 => '<label class="closed">CLOSED</label>'

I order to add conditional values to my actions i add the status column twice, i hide the original and add a second one and add the formatter to it, then i add my showOnValue to the hidden original.

Here is my question, giving that the Formatter has a purely presentation purpose (it might not in some cases), shouldn't the showOnValue value be compared with the raw value and not with the formatted one?

This is because i shouldn't need to add the status column twice, but just once, so if i am comparing with '1', then:

1 === '<label class="open">OPEN</label>' // works only if compare is '==' as a boolean
// having 1 =  the state i want to compare with
// '<label class="open">OPEN</label>' = the formatted value of column 'status'

should be:

1 === 1
// 1 = the state i want to compare with
// 1 = the raw value of column 'status'

Is this the expected behaviour or did i missed something?

Thanks.
