Although you would normally perform the ->getData_serial() method on the table object which contains multiple tickets, if you are saying that the tickets do not actually exist as rows in a table but are generated "on the fly", then a different approach is needed. After the call to ->getData_serial(), which returns a resource, the framework will then obtain records one at a time by calling $resource->fetchRow(), which will either return another row or it will return FALSE to signify EOF. Note that it is possible in your _cm_fetchRow() method to construct another row manually, so although the ->getData_serial() only reads a single record you can call ->fetchRow() as many times as you like, and the processing will only stop when ->fetchRow() returns FALSE.
