We should be able to remove the test for a JavaScript action and generate the
appearance regardless. If there is a JavaScript
action that should take the value and recalculate the entry. What happens here
(I think as I don't have the form) is that the
JavaScript is attached to an interactive event which is not triggered which
results in an empty field.
OTOH this is also a defect of the form itself as the scripting assumes
interactive use.
If we remove the check we will take the provided string as is and won't execute
the JavaScript (as we can't) which might lead to
a visual representation which is not intented e.g. the JavaScript typically
does date formatting in a way that differs from the
string being passed.
BTW that's the reasoning why we don't set the appearance if there is a
JavaScript action attached.
WDYT?
