He tratado de muchas maneras de ver cual es el error... pense que era algun problema
en el modelo web, el cual he cambiado una infinidad de veces y nada siempre me sale 
lo mismo.. inclusive utilizando el que biene de muestra con la unit..

Si coloco la unit con "prepare" y luego la unit con "pay" en la misma area me envia 
el error de que el token ya esta usado en una transsaccion anterior y me envia 
el codigo del error.

Si coloco la unit con "prepare" en un area y luego la unit con "pay" en otra area me sale el mensaje 
indicado mas arriba pero al precionar F5 se puede continuar.. pero, obviamente eso no esta bien.



se puede solucionar esto Para poder implementar correctamente una store con webratio?


De antemano gracias por su respuesta.

Hi everybody,

I'm sorry for the problem you encountered with the Pay Pal component.

We are currently working on a new version of the component which fixes several problems.

As far as the new version will be released on the WebRatio Store I will contact you.

Efectivamente lo acabo también de comprobar y no está operativo, te aconsejo que dentro de la web store de webratio, reportes el incidente para que sea resuelto, por lo desarrolladores de origen.

Hola, tranquilos no contesten todos a la vez...

Churos... que lastima, confirmado..  no se puede realizar ni siquera una sola compra .. al regresar de paypal..  al parecer hay un objeto que no se inicia... y se crea la exepcion.. 

 

java.lang.NullPointerException

 

Que lastima, pero parece que no se puede implementar una tienda con webratio... y con lo que me gustaba.!!
