Hi ,
I am getting following NPE [1]when trying to subscribe to a topic. It is
due to the null value of "CarbonContext.getCurrentContext()" coming from
the following method in event.core module. I built the complete platform
yesterday. Is this a known issue ?
Thanks
Shammi
public static String getLoggedInUserName() {
String userName = "";
if (CarbonContext.getCurrentContext().getTenantId() != 0) {
userName = CarbonContext.getCurrentContext().getUsername() + "@"
+ CarbonContext.getCurrentContext().getTenantDomain();
} else {
userName = CarbonContext.getCurrentContext().getUsername();
}
return userName.trim();
}
[1]java.lang.NullPointerException
