Presence validation does not take boolean values into account

[mono blaine]

The implementation of Ext.data.validations.presence returns incorrect results when a boolean model field is considered.

/**
 * Validates that the given value is present.
 * For example:
 *
 *     validations: [{type: 'presence', field: 'age'}]
 *
 * @param {Object} config Config object
 * @param {Object} value The value to validate
 * @return {Boolean} True if validation passed
 */
presence: function (config, value) {
    // No configs read, so allow just value to be passed
    if (arguments.length === 1) {
        value = config;
    }

    //we need an additional check for zero here because zero is an acceptable form of present data
    return !!value || value === 0;
}

Therefore the presence validation of a false value returns false (it should be true instead) in this case.

/**
 * Validates that the given value is present.
 * For example:
 *
 *     validations: [{type: 'presence', field: 'age'}]
 *
 * @param {Object} config Config object
 * @param {Object} value The value to validate
 * @return {Boolean} True if validation passed
 */
presence: function (config, value) {
    // No configs read, so allow just value to be passed
    if (arguments.length === 1) {
        value = config;
    }

    //we need an additional check for zero here because zero is an acceptable form of present data
     return !!value || value === 0 || value === false;
}

might be better.
