    Possible core bug

    In the CMS, I go to Members, open the search node and search for * (wildcard) and I get the yellow screen of death:

    Server Error in '/' Application.

    Object reference not set to an instance of an object.

    Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

    Hi Tom,

    Just tried to replicate this. I got an exception when submitting an asterisk in the top search box, but didn't get an error in the Members > Search dashboard panel.

    Best bet is to raise the issue over on CodePlex: - the core team will review it (leave as much info about your Umbraco set-up as possible).

    Cheers, Lee.
