In our HR service catalog on our HR portal we have many service catalog items that leverage record producers to turn employees' requests into HR cases. Out-of-the-box (OOB), the HR record producer scripts call functions in the sn_hr_core.hr_ServicesUtil script include to pass the information entered by the employee into the case.
We now have a requirement that demands changes to these functions. We don't want to customize the OOB functions, and are instead looking at creating a wrapper around this script include to override the functions. So far however, we've been unable to get this to work.
What we've done is create a custom script include within the same sn_hr_core scope that overrides the functions as follows:
var SIG_hr_ServicesUtil = Class.create();
SIG_hr_ServicesUtil.prototype = Object.extendsObject(sn_hr_core.hr_ServicesUtil, {
initialize : function(_case, _gs) {
sn_hr_core.hr_ServicesUtil.initialize.call(_case, _gs);
},
createCaseFromProducer : function(producer, rpId) {
... (our custom code here)
},
type: 'SIG_hr_ServicesUtil'
});
In our record producer script we call the custom function as follows:
new sn_hr_core.SIG_hr_ServicesUtil(current, gs).createCaseFromProducer(producer, cat_item.sys_id);
However, when doing so and submitting a service catalog item from our portal, we get an error and the overriding is not working:
org.mozilla.javascript.EcmaError: undefined is not a function.
Caused by error in <refname> at line 1
==> 1: new sn_hr_core.SIG_hr_ServicesUtil(current, gs).createCaseFromProducer(producer, cat_item.sys_id);
What are we overlooking here? Is it even possible to override the OOB functions without customizing the script include?
