title: Why is the "Use default value from package" option disabled?
body: <p>I've got a SSIS project deployed to SQL-Server 2012. When I go to configure the <em>project</em>, the only option I have to set any of the parameter values is <strong>Edit value</strong>. The <strong>Use default value from package</strong> is disabled. I can understand why this might be the case for project level parameters, but I'd expect that package level parameters would could use the default values. What controls this?</p>
