The packageForPrint API has changed in the latest release of InDesign CC (10.x), breaking one of our plug-ins. We cannot find documentation for the API, but the error thrown is straightforward: "Error Invalid value for parameter 'includeIdml' of method 'packageForPrint'. Expected Boolean, but received "". Error: Invalid value for parameter 'includeIdml' of method 'packageForPrint'. Expected Boolean, but received "". We could, of course, experiment with param passing, but it would be much easier if someone out there knew the changed API. Thanks for anyone's help in advance.
