I have an interesting behavior of the xmlrpc deleteRegistration method. The first time I click a button in my web application i get a null pointer exception in the logs of openfire. Clicking a second time and everything works fine…
I’m not quite sure if the problem is in my code or if it is a problem with the xmlrpc? Anyone else with this problem?
Ack, what’s the NPE??
Hm:
that’s everything that I get in the “warn”-section of the log viewer:
2007.08.08 15:31:09 java.lang.NullPointerException: null
It seems like that with the first try I get disconnected from the transport and with the second try the transport will be deleted…
You act as if that’s not informative =D
Uhm. Hrm. You know, I think I might know what’s up with that and it might be fixed in my latest build. (I’m aiming to have 1.1.1 out real soon now, lots of little buggies that are fixed)
Still, is there anything at all in error.log? If you have debug.log turned on, is there anything that shows up there?
hehe, yes… i litte bit more info would be cool… just to know that it is not my fault…
ok, here is the debug stuff, I paste everything that occurs after I press the deleteTransport button the first time…:

After that the registration is successfully deleted!
HTH
Cheers
Would you mind trying it with the attached version? I think I might have fixed what was causing this. BTW, as an additional bonus, theres now a getActiveTransports command to get the list of activated/enabled transports. =)

Well done… it works!!! If life would be so easy all the time 
Thx a lot! And I’m looking forward to try out the new xmlrpc function…
I’ll post feedback if it works…
