[OpenLayers-Users] Error when parsing array with OpenLayers and Protocol.HTTP()

[Ezequiel Gonzalez Rial]

Hi,

If you are generating this information, check this part:

> {
>    "origin": "2013P00109",
>    "type": "LJ",
>    *"naf": "5610A",*
> },
>

the final comma in the naf line shouldn't be there.

Regards,
Ezequiel
