Problem with Mashup

Plugin: Comprehensive Google Map by Alexander Zagniotov
Custom field Field map-point saves: lat,long{}icon.png

If I put:

   <wpv-loop>
[types field="map-point"][/types]
</wpv-loop>

If outputs the list of map-point of all my custom entries, but the plugin needs to separate each point with "|"

I try with:

   <wpv-loop>
[types field="puntomapa" separator="|"][/types]
</wpv-loop>

But it doesn't work.

I try this:

   <wpv-loop>
[types field="puntomapa"][/types]|
</wpv-loop>

And It print all the markers, but it makes an error, because the last field is empty, I need to remove the last seprator "|" from the list

What I'm doing wrong ?

Thanks!
