    Hello!

    We've just recieve an information from application users that there is a problem with list in application.
    We can't reproduce it, as it had occured on the new Nokia Lumia 1020.
    Bellow is an information about this exception.
    Could You give us some information about where to look for this problem, please?

    Best regards

    Hi Bartlomiej,

    Thanks for writing and for the provided stack trace.

    Is it possible for you to share with us the project in which this error happens so that we can try to reproduce it on our side?

    You will have to open a new support ticket in order to be able to attach your project.

    Thanks for your time.

    Regards,

    Unfortunatelly we can't share our project as the code belong now to our client.
    This application is already on the marketplace so You can download it
    http://www.windowsphone.com/pl-pl/store/app/historydaily/a8eff1d1-fa2c-455a-9bc9-d811db4219ab

    An error occured on events list page which can be reached from panorama item named "archive" using "more" option.

    If this is ok to You then  I will create a support task.

    Best regards,
    Bartłomiej

    Hello Bartlomiej,

    Thanks for writing back.

    I would like to inform you that we have been able to reproduce the issue. We are yet to determine what the exact steps of reproducing it are but we will investigate where in the source code the problem might be and will release an Internal Build with a fix for you to see if it addresses the issue.

    Let me know if you have further questions or need assistance.
