How do you pass through selected rows in between mashups?

Hi,

So I have a parent mashup that displays various mashups within, depending on the context selected by the user. On the top level, there is a list of sensors that can be selected and a map of those sensors that are selectable as well.

Now, due to spacing constraints with the map, I added a larger map in a mashup within the parent mashup.

I'm having issues where selecting meters on the larger map (i.e. changing the selected row) does not reflect what is truly selected on the parent mashup.

Is there a solution to this?

Thanks
