Hilfe bei Flashchat Modul (fehlerhaft) gesucht
Eingetragen von Herr Lich (109)am 29.07.2010 - 17:51 Uhr in
Hallo Leute, wenn ich mit Drupal 6.17 das Flashchat Modul für den Flashchat 6.0.8 verwende und den Block Flashchat aktiviere, bekomme ich die Fehlermeldung
Call to a member function next() on a non-object in...
next ist aber keine member function, sondern gehört zu php dazu. Was könnte da falsch laufen?
Nachdem ich 2 Zeilen auskommentiert hatte, die die Funktion next() aufrufen, wurde zumindest der Block dann angezeigt und die Seite war wieder nutzbar. Allerdings werden so keine Räume und keine Chatter angezeigt.
Wer könnte mir bei der Lösung des Problems helfen? Ich habe jetzt alternativ ein unbeliebts iframe eingebunden, welches die info-embedded.php des Chats aufruft.
Eine Frage nebenbei: Besteht die Möglichkeit, die Chatteranzeige mittels ajax wie bei der Shoutbox zu aktualisieren? Es wäre sehr von Vorteil, wenn es dazu im Konfigurationsmenü eine Möglichkeit geben würde. Leider sind meine Kenntnisse bezgl Drupal noch annähernd bei Null, um es selbst zu verwirklichen.
Der Quelltext des Moduls sieht folgendermaßen aus:

Sowas kommt in die issue queue des Projekts.
Danke! Das muss man ja auch

Danke!
Das muss man ja auch erstmal wissen. ;-)
Für mich ist ein Forum immer der erste Anlaufpunkt gewesen. Aber nicht schlecht, wenn es für solche Fälle bei Drupal direkt einen Bereich gibt. Dann werde ich mich später mal drum kümmern, das dort einzustellen.
