title: Modified Reporting Services Report - RDL does not change?
body: <p>I have a Reporting Services 2005 report that had an error: "Parameter UserID is read-only".  After doing some research, I found a solution that worked.  I opened the report from the Report Manager web interface and changed this:</p>
  
  <p><img src="https://i.stack.imgur.com/7o2yc.png" alt="before"></p>
  
  <p>..to this:</p>
  
  <p><img src="https://i.stack.imgur.com/EZQxV.png" alt="after"></p>
  
  <p>After this change, the report works!  Great!</p>
  
  <p>So, I figure I will download the modified RDL so I can see the change and get the corrected RDL into my source code repository.  So, I download the RDL:</p>
  
  <p><img src="https://i.stack.imgur.com/rnYpG.png" alt="Downloading the RDL"></p>
  
  <p>But my diff tools tell me that the "before" version of the RDL is identical to the "after" version of the RDL.  Convinced that my diff tool was mistaken, I tried another.  Sure enough, there is no difference in the RDL.</p>
  
  <p>What am I missing?  Is the change reflected somewhere other than the RDL, or is Reporting Services not coughing up the correct version of the RDL?  In either case, how can I get the correct version of the RDL?</p>
  
  <p>Thank you.</p>
