    Ajax and PageRequestManagerServerErrorException

    Hello,

    I have an asp:UpdatePanel with some controls in it.
    The UpdatePanel has a Timer as a trigger and a button inside the
    UpdatePanel as a trigger.

    All works fine, but sometimes I get the following error:

    Sys.WebForms.Pa geRequestManage rServerErrorExc eption: an unknown error
    occurred while processing the request on the server. The status code
    returned from the server was: 500

    The button updates some records in an Oracle database and the timer gets
    some records from the same Oracle database.

    I have the impression that the error occurs when the button and the
    timer event execute at the same time, but I am not totally sure about
    that. Maybe it has something to do with accessing Oracle at the same
    time from the same client computer?

    Does anyone recognize this exception and knows a solution for this?

    Greetings,
    Chris

      RE: Ajax and PageRequestMana gerServerErrorE xception

      the error means that on the ajax postback, your page is throwing an error.
      you shoudl add error logging and error handling to the page.
