Hi,

in your code

IUser iuser = WPUMFactory.getServiceUserFactory().getServiceUser("cmadmin_service");

I am not getting "WPUMFactory". is it not giving any desingtime code error. coz when i used your code its showing "WPUMFactory" is not known. It should be only "UMFactory".

I used "UMFactory.getService........ and also I am not getting "getServiceUser()" method as deprecated.

Please correct me if I am wrong.

regards,

Pradeep

Hi,

getServiceUser("cmadmin_service") is returning null values or its pointing the user which doent exist. check the name "cmadmin_services" once, and also check whether it has any values.
