title: RDLC subreport filter error
body: <p>I'm using a Local Report in Report Viewer 2008.</p>
  
  <p>I'm trying to do something I think should be real simple. I have a subreport that I want to do some filtering on. I want to do a skip/take functionality, although I can't even get the most basic of filters working.</p>
  
  <p>The subreport has a matrix. I've tried adding filters to the report datasource (Report -> Data Sources... -> Properties... -> Filters) and to the matrix itself. Unless I do something like =true for a filter, I get an error, subreport could not be shown.</p>
  
  <p>For an example, I have an integer called Order in my data source. I thought I could do =Fields!Order.Value > 1 and that would make the report use every row but the first one, but I get the subreport error.</p>
  
  <p>Running the application in the debugger will display report warnings to output. I was expecting something a bit more helpful, but no luck...</p>
  
  <p>Warning: An error occurred while executing the subreport ‘ImageSubreport’: An error has occurred during report processing. (rsErrorExecutingSubreport)</p>
  
  <p>I've used filters a lot before, so I'm kind of confused why this doesn't work.</p>
