--- Zitat von: eknori am 30.12.05 - 17:18:50 ---Axel:

Wenn ein Supporter angegeben wird, der keine Tickets hat ( also nicht in der DB existiert ) springe ich aus der function mit exit function raus.

entsprechend wir das hier als response geliefert; kann man damit was anfangen, sprich im Frontend entsprechend behandeln  ??

--- Ende Zitat ---
GETALLTICKETSBYSUPPORTERR scheint hier bei leeren Collections null zu sein. Ich find das nicht so gut. Wenn es schon ein Objekt gibt, dass als eine Art von Container für den Array dient und dazu noch eine ARRAY.length Variable (wie immer die heisst) hält, dann sollte nicht das ganze Objekt null sein. Das muß irgendwie gehen, dass in GETALLTICKETSBYSUPPORTER ein Array[0] zurückgegeben wird. Das wäre wesentlich besser.

Den Rest mach ich später. Sieht aber gut aus.
Vielleicht ist es keine schlechte Idee noch ein bischen Funktionalität für die Todos anzubieten.
Ich werde jetzt schneller.
Am nervigsten war es, vernünftige datenstrukturen für die Collections, die in den Views angezeigt werden, hinzubekommen.
Je mehr Mühe ich mir hier gemacht habe, desto weniger Arbeit habe ich, wenn ich tatsächlich eine JTable auf diese Daten loslasse.

Java5 war teilweise ein bischen gewöhnungsbedürftig. Generics (dieses Zeugs <String>) sind sehr praktisch. Ebenfalls die ForAll Schleife, in denen kein ForAll als Wort vorkommt. Denke ich kann auch Scott Delap für die Gui folgen, ohne dass mich das aus der Bahn wirft.

Hier ist die zentrale Facade-Klasse, die mit den von Eclipse generierten Klassen spricht und sich die Werte über Webservices holt:

eknori (retired):

--- Zitat ---Die Funktion getTicketDetails ist nicht implementiert
--- Ende Zitat ---
Richtig, ebenso wie die AssignTicket; da existiert bisher nur ein func stub ...

eknori (retired):
@Axel:

Habe die

Class TicketDetails
   Public User As String
   Public Supporter As String
   Public ID As String
   Public Problem As String
   Public Solution As String
   Public Status As Integer
   Public application As String
   '... keine Ahnung was sonst noch
   'Public AssociatedTodo As ToDoCollection
End Class

eingebaut.

Und CreateTicket gibt jetzt die TicketNummer als string zurück.

Mark³:
ist die Testdatenbank noch online?
Ich habe gestern und heute mal mit dem .NET WebService Studio getestet, bekomme aber immer
--- Zitat ---System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.NullReferenceException: Object reference not set to an instance of an object.
--- Ende Zitat ---
Hab unseren Proxy bereits eingetragen, klappt aber noch nicht...
