Durante los últimos días he estado tratando de encontrar una manera de mostrar un punto en un mapa a partir de un par de coordenadas introducidas en un formulario. Empecé con el ejemplo de abajo y luego añadí el formToJSON Dijit. Ambos componentes parecen funcionar, pero no puedo averiguar cómo "engancharlos" juntos.
¿Alguien tiene alguna idea o estoy haciendo todo mal?
