When updating a WPF project from 13.0.4 to 13.0.5, I get an error. My project doesn't show up in the stack dump, and I make no changes to the project other than the version of Crystal that it is installed with. The error shows up on a clean machine using Win XP and Win 7.
Before I show the error, I would like to list a few questions:
- Can this be confirmed as a bug, or am I doing something wrong?
- If this is a bug, is there a way to remove 13.0.5 and reinstall 13.0.4? (It seems like once 13.0.5 is installed, I can't go back and repair the machine)
Code that Causes the Crash
The last line of this sequence worked in 13.0.4, but indirectly causes the crash in 13.0.5:
var reportSource = this.CrystalReportsViewerMain.ViewerCore.ReportSource as CrystalDecisions.CrystalReports.Engine.ReportDocument;
//...modify reportSource
this.CrystalReportsViewerMain.ViewerCore.ReportSource = reportSource;
The Error Message
Object reference not set to an instance of an object.
The Error Message Location
Void UserControl_IsVisibleChanged(System.Object, System.Windows.DependencyPropertyChangedEventArgs)
The Stack Dump
Note, the stack dump doesn't contain a reference to my software. This happens when the visibility changes when resetting the report source.
