Comment # 1 on bug 9982 from Michal Labedzki

Hi,
There is a little better patch commited in [1]. Value field may be not removed
and displays as "<MISSING>" is there is no content. Previously field item
support that, but there was little misstatement between behaviour with item
length = 0 (<MISSING>) and length = -1 (length remaining ~ it still can be 0,
but fail and cause your bug).

Example filter:
btatt.value == ""
So you have all packets that there is no value.
Also filter: "size(btatt.value)==0"


There is also ongoing backport for your 1.10.x version in [2].
