title: Crystal report parameters aren't being prompted
body: <p>I'm working on upgrading our application to use Crystal Reports 2008. (v12)  Currently, we use Crystal Reports 2008 <em>for Visual Studio</em>. (v10.5 <sub>nice naming convention jerks</sub>)</p>
  <p>Most of the time, our application supplies report parameters itself, using the id/name/whatever of the object the user is currently looking at.  This is pretty normal.  However, our users also need to be able to fire up reports directly and supply these parameters themselves.  We are using the <code>CrystalDecisions.Windows.Forms.CrystalReportViewer</code> control to display the report.</p>
  <p>With v10.5, a parameter selection wizard would appear, and all was well. Note the presence of the InvoiceNumber parameter.</p>

  <p>However, when I run our reports against v12, some parameters aren't showing up.  In this example, it's the InvoiceNumber parameter.</p>

  <p>Our report writer says that there is a solution to this which involves changing every report.  I'm unsure of the details.  We have a <em>lot</em> of reports, so I was wondering if there is a solution that can be implemented at the time of report invocation.  Is there an option, property, method, or something to have these missing parameters show up?</p>
