Use refreshVariable with refreshAfter: "RECORD_ACTION" in Task From

I am trying to use a refreshVariable with refreshAfter: "RECORD_ACTION" in a Task From, but the variable does not get refreshed.

Is the use of refreshAfter: "RECORD_ACTION" only possible in a record form, or am I missing something.

I start my from with:

a!localVariables(
  local!contractVersion : a!refreshVariable(
    value: rule!TML_GetMostRecentContractVersion(ri!contract.id),
    refreshAfter: "RECORD_ACTION"
  ),
  ...
)

And in the middle of the form there is a recordActionField:

a!recordActionField(
        actions: {
          a!recordActionItem(
            action: 'recordType!{eb81a0e8-fa2b-4197-960f-cb29539fee9a}Contract.actions.{f1c42920-fefd-4519-b8f7-7d3e8199868b}newContractVersion',
            identifier: ri!contract.id
          )
        },
        style: "TOOLBAR",
        display: "LABEL_AND_ICON",
        align: "END",
        openactionsin: "DIALOG"
      )

the record action is executing without a problem, but the refreshvarable is not working.
