getContent() not working at 2.2

[MarkSmith]

I have a few JS API apps which on Identify use the getContent() method to get hold of all the attribute information which I then format for various purposes for example:

function addToMap(idResults, evt) {
          //run through each feature found
          for (var i = 0, il = idResults.length; i < il; i++) {
              var idResult = idResults;
              var content = idResult.feature.getContent()
              ............etc

This works great at 2.1, but if I change to 2.2 it breaks and the value of my variable 'content' is null as opposed to some nice HTML of fields and values I get at 2.1.

Can anyone please tell me how to get the content at 2.2?  I've tried exploring the reference, but can't work it out.  Thank you,

Mark.

This forum post contains details on how to fix this at 2.2.

Thank you,

This is what I now use:
var content = esri.substitute(idResult.feature.attributes, "${*}")

Rather than this which doesn't work at 2.2:
var content = idResult.feature.getContent()
