Android Question Weird crash with Wait For

[techknight]

Perhaps I am doing something wrong (probably) but I am having a weird crash with Wait For...

Here is the code in question:

        Return 255                'Send a random response from a disconnect, as it doesn't really matter the state of the system
    End If
End Sub

Here is the crash:

Line 935 is the Wait For line:

Not entirely sure why its tossing a number format exception, im only passing an integer down the line.

Calling instance to HAndleConnection: (From another class)

thoughts?

Dangit! wrong forum. needs moved to B4J

Why are you not waiting for a Status_Event on disconnect like you do on connect. Does disconnect not raise a Status_Event?
t?

Because its not used for the Disconnect event. Only connect. Status codes change during the lifetime of the connection, which is why that event is there. But I only need to "forward" those to the connect instance during the connecting period, so thats why I have the wait for there.

I do have a wait for on disconnect, but i dont need the response. This was a class used in other apps too, which is why its there to begin with.

I think i figured it out. I needed an additional Wait For from the parent caller as well, so i had to wrap the CallSub2 in its own wait for complete.
