I figure it should work too.
So here are the 2 small issues, firstly i can not view the server action running in network tab of chrome, because it ran before everything loaded, so a little hard to show you exactly whats in there.
Secondly it runs a single database query to a bunch of linked tables which are all multi record.
this allows me to get to a single binding
<%=_('query_get_my_page_meta_data.mpc_t[0].mpc_body_copy',locals)%>
So i tried using it in a repeat like this
<div id="repeat_containers" is="dmx-repeat" dmx-bind:repeat="<%=_('query_get_my_page_meta_data.mpc_t">
But could not get that to work. any ideas @JonL
