Sugar 7 - Form submitting before client-side validation

Sorry I'm late to this, try this:

({
    extendsFrom: 'RevenueLineItemsRecordView',
    initialize: function (options) {
        this._super('initialize', [options]);
        // add custom message key     
        app.error.errorName2Keys['custom_message'] = 'ERR_CUSTOM_MESSAGE';

        this.model.addValidationTask('check_account_type', _.bind(this._doValidateCheckType, this));
    },
    _doValidateCheckType: function (fields, errors, callback) {
        var receita = app.data.createBean('RevenueLineItems', {id: this.model.id});
        var receita_model = this.model;
        var request = receita.fetch();

        request.xhr.done(function () {
            console.log('Receita: ' + receita.get('id'));
            var receita_op = receita.getRelatedCollection('opportunities');
            var opportunities = receita_op.fetch();
            opportunities.xhr.done(function () {
                //console.log(receita_op);                
                for (var i = 0; i < receita_op.length; ++i) {
                    var opportunity = receita_op.models[i];
                    var op_accounts = opportunity.getRelatedCollection('accounts');
                    var accounts = op_accounts.fetch();
                    accounts.xhr.done(function () {
                        //console.log(op_accounts);

                        for (var i = 0; i < op_accounts.length; ++i) {
                            var account = op_accounts.models[i];
                            console.log(/*"Proposta: "+receita.get('sales_stage')+*/" - Account: " + account.get('id') + " - " + account.get('cnpj_c'));

                            // PROBLEMA: ESTÁ SALVANDO MESMO FORÇANDO OS ERROS!

                            if (receita.get('sales_stage') == 'Closed Won'
                                    /*&& (!account.get('id') || !account.get('cnpj_c'))*/) {
                                console.log("Erro");
                                receita_model.trigger('error:cnpj_required:sales_stage');

                                errors['sales_stage'] = {};
                                errors['sales_stage'].custom_message = true;

                                callback(null, fields, errors);

                                app.alert.show('cnpj_required', {
                                    level: 'error',
                                    messages: 'A Oportunidade da Receita necessita de um Cliente com CNPJ',
                                    autoClose: false
                                });

                            } else {
                                console.log("Ok");
                            }
                        }
                        callback(null, fields, errors);

                    });
                }
            });
        });
    }
})  

Hello, Alan.

I found another way to solve this:

In the PHP logic hook (before_save), when reaching the condition I want, I put the following lines of code:

require_once 'include/api/SugarApiException.php';
throw new SugarApiExceptionInvalidParameter("Validation error message");

When trying to submit the form, it shows the message I put in the exception, preventing the form from submitting.

I don't know if it's the best way to do it, but it was the only way that really worked for me.

Anyway, thanks for the help.

Best Regards,

Ramon Marcondes
