Not sure why this fails - I'd also try
parameters="ognl:{selectedCountryId, selectedLocationId == -1 ? otherCityId : selectedLocationId,
checkIn == null ? null : checkIn.time, checkOut == null ? null : checkOut.time, adultsPerRoom}"
but I'd really go with simplifying the ognl expression of this direct
link, i.e.
moving the code into the java.
PS. listener="ognl:listeners.goToLocationSearch" should be updated to
listener="listener:goToLocationSearch" (faster & cleaner)

The "mystery" is that the error is traced at the DirectLink component;
Tapestry does not have any problem with the Hidden component, arising
suspicions that the problem is not actually that selectedCountryId is null
(it should have a problem with the Hidden component) but that there's
something I'm not doing right with the DirectLink component. What could be
the case?
