Argument is not nullable while using pish.openListener
 

Hi ,



I am trying to register my device to blackberry server using:



blackberry.push.openBISPushListener(ops, this.onData, this.onRegister, this.onSimChange);



But i get the following error: Argument is not nullable



My code is as follows:



registerForNotifications : function() {

try {
var ops = {
port : NotificationConstants.bbPort,
appId : NotificationConstants.bbAppId,
serverUrl : NotificationConstants.bbServerUrl,
wakeUpPage : 'push.htm',
maxQueueCap : NotificationConstants.bbMax


};

console.log("BB PORT "+NotificationConstants.bbPort)
blackberry.push.openBISPushListener(ops, this.onData, this.onRegister, this.onSimChange);
} catch (err) {
alert('openBisError ' + err);
}




Where am i going wrong?

Thanks in advance.



Annuk.
