What your code really want to say is that if `field` doesn't exist,
then it should be treated like if its size was 0. So just say that in
FTL too:

  ${(myDTO.field![])?size}

Another solution is:

  ${(myDTO.field?size)!0}

but it's less telling, also it will hide the error if `myDTO` is null,
which is unintended.
