Service Biulder: Finder mediante una columna Collection

[Víctor A. García Ledesma, geändert vor 14 Jahren.]

Hola,

Tenemos una entidad con una relación many-to-many de la siguiente forma:

<column name="groups" type="Collection" entity="com.liferay.portal.Group" mapping-table="EducarexAnnouncements_Groups" />

Y necesitamos un método finder que filtre mediante dicha columna, ¿Cómo podemos hacerlo?. Hemos probado con este código:

<column name="groups" type="Collection" entity="com.liferay.portal.Group" mapping-table="EducarexAnnouncements_Groups" />

Y obtenemos el siguiente error:

Hola Victor,

creo que no has puesto el codigo del finder que querías poner, no?
