As I began to mention in the comments of my previous post, I trying to store the Reports.ReportResults data into a custom caching object. I am able to store the data by converting the results to a String like so:

Reports.ReportResults results;
String stringResults = (String) JSON.serialize(results);

but when it comes to retrieving the results I seem to be in a bind. I thought I could accomplish this with something like this

String cache = [SELECT Results__c FROM Cache__c WHERE Report_Name__c = :report LIMIT 1].Results__c;
return (Reports.ReportResults) JSON.deserialize(cache, Reports.ReportResults.class);

But unfortunately that returns me with this fatal error:

FATAL_ERROR|System.JSONException: Apex Type unsupported in JSON: Object

Any ideas on if this is even possible or should I be working on a totally different approach? Any help would be greatly appreciated. Thank you.

    Do you have access to Platform Cache? JSON does have some limitations, but I think the cache might work. – sfdcfox Dec 16 '15 at 22:09
  • Never heard of this. I see its caching layer is not available till Winter 16' is this still an option I can try right now? – Xtremefaith Dec 16 '15 at 22:11
  • Alternatively, JSON.deserializeUntyped? You won't get to convert it back directly into a Reports.ReportResults object, but at least you'd have a navigable map... – sfdcfox Dec 16 '15 at 22:13
  • I see it in my setup, but for some reason, we don't have any space allocated (0MB/0MB). It may be that we need to talk to our account executive, but I thought that Session and Platform cache were free, while other types (there's a half dozen or so) are paid cache. – sfdcfox Dec 16 '15 at 22:14
  • The platform cache documentation is definitely speaking my language but the deserializeUntyped seems like a quicker solution. How would that look? Never used it before – Xtremefaith Dec 16 '15 at 22:15

As suggested by @sfdcfox, I have the start of a solution using the newly released Platform Cache using the Org Cache approach described here

Reports.ReportResults results = Reports.ReportManager.runReport(reportId);
Cache.OrgPartition orgPart = Cache.Org.getPartition('local.PartionName');

// Retrieve cache value from the partition
if (orgPart.contains('ReportKey')) {
    Reports.ReportResults cachedResults = (Reports.ReportResults)orgPart.get('ReportKey');
}
// Add cache value to the partition
orgPart.put('ReportKey', results);

NOTE: ReportKey must be alphanumeric

The first time I ran this script I was happy to report that the results were stored as expected. Then, when I ran it the second time, after swaping the cast type from String to Reports.ReportResults the get() method worked as expected and I GOT MY RESULTS!

Kudos to sfdcfox for again being on point, and for opening my eyes to an option I didn't even realize was available.
