Question

How can we use the asyncValidate function from BasePageV2 to verify field population on a page?

Answer

You can view the method implementation in DocumentPageV2. Implement the necessary functionality in a similar way.

Firstly, implement the field population verification method (similar to validateAccountOrContactFilling) that accepts the callback function and execution context as incoming parameters.

Afterwards, call it in asyncValidate.

For example:

asyncValidate: function(callback, scope) {
    this.callParent([function(response) {
        if (!this.validateResponse(response)) {
            return;
        }
        Terrasoft.chain(
            function(next) {
                this.myValidationMethod(function(response) {
                    if (this.validateResponse(response)) {
                        next();
                    }
                }, this);
            },
            function() {
                callback.call(scope, response);
            },
        this);
    }, this]);
}
