Hey Ben -
Thanks again for quick reply and info.
#1 - Ok, I see the 10,000 limit with Standard Set Controllers (https://developer.salesforce.com/page/Paginating_Data_for_Force.com_Applications).
Question - Why does a standard SFDC Tab page allow for more than 10,000 records to be returned (page size 200)? What technique is standard tab page using?
#2 - Makes sense now. The dot I wasn’t connecting on this one was the first call is SOQL, the rest are controller methods but based on what the math says the next page should be.
Thanks!
