GlideController functionality in Scoped app

[Daniel Peel]

Currently I have an error function in a script include... I'm using in global and I want to move this process into a scoped application... I'm using GlideController to take a passed status value 430, 431 etc and use it to lookup a constant.  This works fine... but how can I do this in a scoped app... the GlideScopedEvaluator() doesn't seem to work the same way.

Thanks

//this are constants at the top the SI
ERROR430/*old 415*/ = 'The following required fields are missing: ';
ERROR431/*old 416*/ = 'The following field has an incorrect value: ';
ERROR432/*old 417*/ = 'The following record was not found: ';
ERROR433/*old 419*/ = 'The following error occurred: ';


//this is the function that is called and uses those for standard output.
_errorHandle: function(status,messageAddOn,calledFunction){

var message = '';
var getErrorMessage = GlideController;
var errorConstant = 'ERROR' + status;
var errorMessageFound = getErrorMessage.evaluateString(errorConstant);

if (errorMessageFound){
message = errorMessageFound + messageAddOn;
}
else {
message = messageAddOn;
}
var cmxError = new sn_ws_err.ServiceError();
cmxError.setStatus(status);
cmxError.setMessage(message);
cmxError.setDetail("Failure in: " + calledFunction);
return cmxError;
},

It is part of a SI... I didn't think I needed to share the entire script as it's wasn't relevant, I could have indicated it was in a SI. I updated the OP

Using the code above... I'm returned this
TypeError: Cannot read property \"ERROR430\" from undefined.  

@Pranesh I listed I tried with GSE and that doesn't work the same way as the controller does in Global.  I was using GC to turn the string into a variable... and get the value that way.

try this

STATIC_PROPERTIES: {
		ERROR430:'The following required fields are missing: ',
		ERROR431:'The following field has an incorrect value: ',
		ERROR432:'The following record was not found: ',
		ERROR433:'The following error occurred: ',
	},
	
	initialize: function() {
	},

	_errorHandle: function(status, messageAddOn, calledFunction){
		var message = '';
		var errorConstant = 'ERROR' + status;
		var errorMessageFound = this.STATIC_PROPERTIES.errorConstant;

		if (errorMessageFound){
			message = errorMessageFound + messageAddOn;
		} else {
			message = messageAddOn;
		}
		var cmxError = new sn_ws_err.ServiceError();
		cmxError.setStatus(status);
		cmxError.setMessage(message);
		cmxError.setDetail("Failure in: " + calledFunction);
		return cmxError;
	},

Pranesh, this not how Javascript works.

Daniel, the code I shared works perfectly.

var myClass = new MyClass();
var errorObj = myClass._errorHandle(430, 'my_field', 'myFunction');
gs.info(errorObj)

output:
*** Script: [object ServiceError]

Taking your path... I did this and it worked... script below edited to only show changes

	
initialize: function() {
//put this back in the initialize and changed the : to = ... 
STATIC_PROPERTIES = {
	ERROR430:'The following required fields are missing: ',
	ERROR431:'The following field has an incorrect value: ',
	ERROR432:'The following record was not found: ',
	ERROR433:'The following error occurred: ',
}

},

_errorHandle: function(status, messageAddOn, calledFunction){
	var message = '';
	var errorConstant = 'ERROR' + status;
//removed this.
var errorMessageFound = STATIC_PROPERTIES[errorConstant];

You must make sure that you are defining the STATIC_PROPERTIES on the prototype of your class like in my example, perhaps you put them in the wrong place in your code. I promise you, it 100% works.
