mashups of custom post type posts

HI Guys,

I am trying to use the map widget to create a mashup for maps that i attached to listing posts (directory plugin). i have tried the different short codes [map query=”all posts”], [map query=”tag=tagname”] and so on, but nothing comes up (not even an empty map) – like if there was no widget there. However when i created a map in a regular “post” type post it did work and the map showed up. is the mashup suppose to work with custom post type at all or am i doing something wrong?
