- Summary:
Fix bugzilla Bug 188814 Exception is thrown out when preview results of a joint data set joining from a sample and a flat [0706]


- Bugzilla Bug (s) Resolved:
188814

- Description:

This bug has fixed in 2.2 before. It is caused by the cached session state has changed when fetching its left and right resultset metadata. This error will occur when preparing left dataset query, then preparing right dataset. But once we had prepared right dataset, the left dataset’s result set metadata will never be fetched since the cached states has changed by right dataset. So we should fetch its corresponding metadata on time. Fix it in 2.1.3 branch!
