I'm trying to pass a value to a variable in an apex trigger from an apex controller in an effort to control whether the the code in the trigger is executed.

In myController initialization, I try to set this variable:


public myController() {

        CaseTrigger.isComingFromEmail = true; 



trigger CaseTrigger on Case (before insert){

    public static boolean isComingFromEmail = false;

    if (isComingFromEmail) {
    else {
//Actual Processing Here

The error received on myController:

Variable does not exist: CaseTrigger

Triggers are not classes, and you shouldn't reference them like this. You should create a separate class to store your static variable, and then reference this class in both your controller and trigger.

    I don't think so. But it does illustrates the pattern. I'd prefer Akram G's solution instead, since you can reuse it on other triggers latter as well. May 19, 2019 at 20:26
  • Mihai Neagoe's post on salesforce.stackexchange.com/questions/61371/… is also a good example of the pattern that Sebastian tries to illustrate. May 19, 2019 at 20:28
