title: SSRS not letting me change dataset of a table
body: <p>I have a report with a table in it. I need to change the dataset that this table uses. When I go the tablix properties and try to change the DataSetName, it automatically gets reverted back to the original dataset instead of the new one I selected. </p>
  
  <p>Any ideas on how to fix it and why it's happening? </p>
