SharePoint 2010 Rendering MultiChoice Fields [object Object]

gregjss

I have a similiar problem to mccdg's question SharePoint multiple selection choice field returns "object object". The main difference is that I'm using SharePoint 2010 with ListData.svc.

In my case, when I use the following code to render the expanded data the datatable still displays [object Object]

{ "mData": "ContactMethod",
  "mRender": data.d.results.forEach(function(d){
       d.multi = d['ContactMethod'].results.map(function(s){return s.Value}).join('; ');
   })
},

When I drop d.multi into the console log I see the results I'm looking for but the results are not rendered in the table.

What am I missing?

Thanks in advance.
