RestDatasource.transformResponse and componentId

[JohnBlack]

Hi,
What I'm trying to achive is to send the search criteria in an encoded JSON string because PHP dosen't do well with the way SmartClient sends them ( fore more info see the this thread http://forums.smartclient.com/showthread.php?t=2184&highlight=transformRequest )

Now, my question is about the componentId value which at some point is set to "(cacheAllData fetch)" ( Line 15980 in SC_SNAPSHOT-2012-02-11_v8.3d/LGPL Deployment build).
What is this all about? :)

Oh, and another question, is there a simple way to get the component that uses the datasource (without using eval) ?

transformRequest: function (dsRequest) { 
    var data = this.Super('transformRequest', arguments)

     if(dsRequest.operationType == "fetch" && dsRequest.componentId != "(cacheAllData fetch)") {
      var component = eval(dsRequest.componentId);
      data.pvCriteria = isc.JSON.encode(component.getCriteria());		
     }				
     return data;
}

Thanks in advance,
John
