Uploading custom.js files with the same class name on the application and tenant levels

Uploading custom.js files with the same class name on the application and tenant levels is not recommended. This could result in unpredictable behavior. When two custom event handlers are bound to the same event (tenant level and app level), there is no guarantee which handler is called first. This is under the control of the JavaScript engine. Rewrite your JavaScript to avoid this situation.

Incorrect CustomEvantHandler in Custom JavaScript

Custom.js scripts can be uploaded at two levels in :

• Application level (i.e. inside an open application) -  At the application level, you must use the CustomEventHandlers JavaScript object.  
• Tenant level - The custom.js can only be uploaded to the tenant level by the tenant administrator.  At the tenant level, the custom.js file must use the TenantCustomEventHandlers JavaScript object.  
• If a custom.js file contains the wrong custom handler for the level you are uploading it to, you may see a delay in loading and the custom.js will not work. Verify that the CustomEventHandler is correct.

 A designer creating forms/flows in the application will have access to both custom scripts. Both scripts will function properly.
