How to check if MIGX TV input is empty?

I want to check whether TV INSIDE MIGX (not the TV with type of MIGX, but the TV, which I define in JSON config) is empty, and show/hide a block inside the output depended on the result.

Let's assume I have a field.

        {
            "field": "title",
            "caption": "Title"
        }

Inside

getImageList

call I'm checking if the input is filled.

[[getImageList?
        &tvname=`MIGXTV`
        &tpl=`@CODE:
                 [[!if?
                        &subject=`[[+title]]`
                        &operator=`is`
                        &operand=``
                        &then=`Empty`
                        &else=`Filled`
                  ]]
        `
]]

But this doesn't work, I always get "Filled" regardless of the real value.

This check also doesn't work

[[!if?
         &subject=`[[+title]]`
        &operator=`is`
        &operand=`[]`
        &then=`Empty`
        &else=`Filled`
]]

The field is not even equal to itself. The next check returns "Not equal"

[[!if?
         &subject=`[[+title]]`
        &operator=`eq`
        &operand=`[[+title]]`
        &then=`Equal`
        &else=`Not equal`
]]

What I'm doing wrong here?

creates a real chunk for the tpl.
The tpl in CODE only replace the placeholder but does not execute snippets.

if you look at the source https://github.com/Bruno17/MIGX/blob/master/core/components/migx/elements/snippets/getimagelist.snippet.php
you also have the where parameter !

Thanks! WHERE is the exact thing I was looking for! Moving template to chunk also worked, but it's strange, because I had tried that before with no luck
