The following PHP code is executed from a client (javascript) code:

try {
$result = $client->call('Groups_GetRecipients', array("groupid" => $id));
debug("Groups_GetRecipients finished");
// additional code here is NOT executed - never get to this point
}
catch (Exception $exception) {
debug("Caught exception: " . $e->getMessage());
}

according to the client side the execution is finished but in the server side i don't see any message - it seems that the call method was not finished successfully but it also didn't throw an exception. i'm not sure how can it be that from the client point of view the script was finished but i don't see any message in the server side.

any ideas ?

being php legacy code, nusoap does not throw any exceptions. See the samples on how to handle errors.
