¿Cómo reescribir la plantilla?

O, planteado de otra manera:

¿Cómo interactúa <PluginOutlet @name="search-menu-before-advanced-search" /> con el componente search-menu en el conector? Por ejemplo, si quiero obtener el valor de la instancia this.search, intenté usar appEvents pero no funcionó correctamente.

2

El punto de extensión no tiene parámetros, por lo que no interactúa con el componente en absoluto.

3

¿Entonces no hay ninguna forma de lograr la interacción? ¿No deberían funcionar los appEvents?

4

Supongo que, si realmente lo necesitas, podrías hacer un PR para agregar argumentos al outlet.

También está el servicio search, que podría ayudarte.
