Error 1214 when using GROUP BY in my view - sql

Question

I've got a problem with an view on my database. All other views are working correctly, but when I'm trying to add a GROUP BY statement behind my query,
then I'll get the next Error:
1214 - The used table type doesn't support FULLTEXT indexes
I've set all my tables to ISAM, and i noticed the whole problem is in the GROUP BY statement.
My query looks like this:
CREATE VIEW `id_winkels`
AS
SELECT
`w`.`w_id` AS `w_id`,
`w`.`k_id` AS `k_id`,
`w`.`w_naam` AS `w_naam`,
`w`.`w_logo` AS `w_logo`,
`w`.`w_homepage` AS `w_homepage`,
`w`.`w_straat` AS `w_straat`,
`w`.`w_huisnummer` AS `w_huisnummer`,
`w`.`w_postcode` AS `w_postcode`,
`w`.`w_woonplaats` AS `w_woonplaats`,
`w`.`w_land` AS `w_land`,
`w`.`w_actief` AS `w_actief`,
`w`.`w_datum` AS `w_datum`,
COUNT(`p`.`p_id`) AS `totaal`
FROM `Winkels` `w`
LEFT JOIN `Producten` `p`
ON `w`.`w_id` = `p`.`w_id`
GROUP BY `w`.`w_naam`
Is there another option to count the amount of products by my shop without useing a group by?
When I'm running the query without the group by statement, it will return my total amount of product in one row.

As you only select fields from Winkels, you should get the product count in a subquery rather than joining the tables:
CREATE VIEW id_winkels AS
SELECT
w.w_id AS w_id,
w.k_id AS k_id,
w.w_naam AS w_naam,
w.w_logo AS w_logo,
w.w_homepage AS w_homepage,
w.w_straat AS w_straat,
w.w_huisnummer AS w_huisnummer,
w.w_postcode AS w_postcode,
w.w_woonplaats AS w_woonplaats,
w.w_land AS w_land,
w.w_actief AS w_actief,
w.w_datum AS w_datum,
(
select count(*)
from Producten p
where p.w_id = w.w_id
) AS totaal
FROM Winkels w;
