Database diagram error - Object reference not set to an instance of an obje

Toad for SQL Server
1

Evaluating trial version 5.5.0.1073, getting the following error periodically, I assume it’s doing a background save:

Object reference not set to an instance of an object.
Stack trace:
at Quest.Toad.ModelerDrawing.DrawingControls.RelationObject.WriteXml(XmlElement node)

at Quest.Toad.Diagramming.DiagramForm.SaveAutoRecoveryFile(String file)
at Quest.Toad.DocumentRecovery.DocumentRecoveryManager.SaveRecoveryFile(DocumentForm documentForm)

Also get this error when trying to save a diagram:

System.NullReferenceException

Let me know if any more details will help

Hello,
you definetelly have some issues with file saving. You are right - first error is about autosaving documents and second appears when you try to save it manually.

Toad stores temp files in this directory:
\Toad for SQL Server 5.5 Trial\Document Recovery\

you can access App Data filder from Help->About form.

When do you see second error - on just pressing Save button or when you press OK in Save dialog?

Are you able to save any ther document to the same place - let’s saye Editor file.

regards,
Alex
