Set
 

 
Actionerrors error = new actionerrors ();
If ("login". Equals (Status )){
If (this. ID = NULL | "". Equals (this. ID )){
Error. Add ("ID", newActionmessage("ID. null "));

This is
 

 
Actionerrors error = new actionerrors ();
If ("login". Equals (Status )){
If (this. ID = NULL | "". Equals (this. ID )){
Error. Add ("ID", newActionerror("ID. null "));
}
}
