How to override custom front-end handler ?

You won't see the handler in your replacing page, however, you can still override it. For example, if the base page has a request called this: 

{
	request: "usr.MyCustomRequest",
	handler: async (request, next) => {
		// code is here
 
		return request?.handle(next);
	}
}

In your code in the replacing page, you could add:

{
	request: "usr.MyCustomRequest",
	handler: async (request, next) => {
		// YOUR code here, as needed
 
		// the line below calls the base page's handler
		return request?.handle(next);
	}
}

If you don't want the base page's handler to run, just omit the line below in your code:

return request?.handle(next);

Then with that line gone in your handler in the replacing page, the base page's handler won't run at all since it won't get called. If you still want it to run, but then your code does other stuff after it is done, you could do this: 

{
	request: "usr.MyCustomRequest",
	handler: async (request, next) => {
		// let base page handler run first
		const result = await request?.handle(next);
 
		// now do your stuff
 
		return result;
	}
}

Hopefully, that makes sense.

Hi Ryan,

Thanks for the response..

I tried that and the good news is I can change the handler (it works), but the parent handler is still called 🥲

{
handlers: /**SCHEMA_HANDLERS*/[{
				request: "crt.CloseChatRequest",
				handler: async (request, next) => {
					const chatId = request.recordId;
					const category = request.category;
					let categoryId;
 
					console.log({chatId, category,categoryId});
 
					// return request?.handle(next);
				}	
		}]/**SCHEMA_HANDLERS*/
}

As you can see, it is related to closing the chat. 

In my code, I do nothing except just to console log. 

The expectation is that the chat session is not closed, but the result is that it is still closed.

Am I missing something?

Hmm. Try returning false? (instead of just commenting out the return request.handle(next))

In order to customize a page from a marketplace add-on and override a custom handler in your custom package you can do the following:

1. Create a new client schema in your custom package (e.g., CustomPageSchema).
2. Extend the existing schema and override the handler:

define("CustomPageSchema", ["OriginalPageSchema"], function() {
    return {
        entitySchemaName: "YourEntitySchemaName",
        attributes: {},
        diff: [],
        methods: {
            // Override the custom handler
            onButtonClick: function() {
                // Your custom logic here
                console.log("Custom handler logic");
 
                // Optionally, call the base method if needed
                this.callParent(arguments);
            }
        }
    };
});

3. Register the custom schema in the CustomPageSchema schema.

After that deploy your changes and test.

Also if you don't want to create a new schema you can try to update the existing one.

     1. Add new handler method in the method section:

methods: {
	onButtonClick: function() {  }
}

     
2.Bind the new method to "click" event of the corresponding   button

   diff: /**SCHEMA_DIFF*/[
	{
		"operation": "insert",
		"name": "YourButton",
		"values": {
		"itemType": 5,
		"caption": {
			"bindTo": "Resources.Strings.YourButtonCaption"
		},
		"click": {
			"bindTo": "onButtonClick"
		},
		...
	}
		...
]

Iryna Oriyenko,

That applies to classic pages (and modules) only, not Freedom UI page handlers.

Ryan Farley,

Negative.. the result is still same 🥲🥲

I have tried :

• - return true;
• - return false;
• - comment out the 'return request?.handle(next);'

any clue??
