  • 1.  Project will not open after server crash

    Posted Mar 19, 2010 08:29 AM
    Our Workflow Designer server crashed while I was in the middle of working on our major project.  It now gives me the error below when I try to open the project.  Anyone know if there is a way I could fix this so I don't have to go to a backup copy?

    ["Project Open Errors" window]
    Error opening project: could not read in object

    [Double-clicking on the error gives me the following details]
    Reason: Error opening project: could not read in object

    I think you might be stuck with a backup. It looks like it crashed in the middle of the serialization of the project.

    I ended up working from my backup copy (which was almost 2 weeks old), but thanks to the WorkflowDeploy folder, I lost almost nothing.  I had published my project less than an hour before the server crashed, so there was a very recent deployed version.

    I started from a copy of my backup from a couple weeks ago, then copied all of the .model files, the .WebForms file, and the GlobalData.data file from the deployed project folder to my backup project folder (I hadn't made any changes to the other files).

    When I opened the project, it came up without a hitch.  I have since been able to make changes and publish them with no issues.
