Example

This example checks a parameter passed to it to see if it is equal to "Acme". If it is, the code calls throwError to display an error message saying that the account cannot be "Acme".

if(requestParams.get("name").equals("Acme")) { // message "Account cannot be Acme" will be shown to the user in the UI. Functions.throwError("Account cannot be Acme"); } else { // Normal business logic. } To include new lines in the message, specify <br>: Functions.throwError(“Include <br> for <br> newline”);
