Hi Jade Developers,

Was wondering does anyone know how can this error 1239's cause and solution is?
Trying on Jade5.2 over ThinClient and it seems to meet this error intermittently.
Any help or suggestions appreciated

Regards,

Almost always caused by an exception handler causing further exceptions.

Especially if the exception caused by the exception handler is one of the types that gets handled by the same exception handler.

One way to avoid this problem is to install a local fallback exception handler as the frist thing in the exception handler.

hope that helps,

If your exception handler shows a message box or dialog form on the client PC, and the original exception is something like a thin client disconnect, then this will cause a further exception, and so on. You need to check for the thin client exceptions, particularly 14147 ("connection is not open") and skip any client output.
