Error description

  • Problem
    When two clients are connected to the same Citrix server, and
    both attempt to perform an export to Word, there is a reasonably
    good chance that one of them will recieve a clipboard related
    error which prevents the export from completing.
    
    There is no guarantee of an error, there is a chance that you
    won't see one, but if you do, the most common is simply 'Unable
    to lock clipboard.  Retry?'
    
    ...but you may also see :
    
    'OLE method failed: OLE problem: This method or property  is not
    available because the clipboard is empty or not valid'.
    
    Other errors, which may or may not involve the clipboard are
    also possible.
    
    To Reproduce
     - connect to 2 different citrix clients (I used different
    system authentication, but the same DOORS authentication
     - open 2 different modules and start exporting both to Word
    using the default settings.
    
    At first I didn't get any errors, but after 1 appeared I ended
    up seeing several, even after restarting the DOORS sessions.
    
    Possible Workarounds
    Use a local client

    ****************************************************************
    When running under Citrix environment, if there are multiple
    Word exporters running simultaneously, Word exporter might
    throw one or more of these three error messages:
    
    1) ERROR: "CRCRD5445C: Unable to lock clipboard. Retry?"
    
    2) ERROR: "Failed to set clipboard contents."
    
    3) ERROR: "OLE problem: This method or property is not
    available because the Clipboard is empty or not valid"
    

Problem conclusion

  • 1) ERROR: "CRCRD5445C: Unable to lock clipboard. Retry?"
     Clipboard lock is now locks the related Citrix session
    instead of all sessions.
    
    2) ERROR: "Failed to set clipboard contents."
     This error is seen when DOORS failed to open the clipboard.
    Clipboard is a system resource and opening the clipboard
    might fail, if it's already been used. Open clipboard
    functionality in DOORS is made more error prone.
    
    3) ERROR: "OLE problem: This method or property is not
    available because the Clipboard is empty or not valid"
     Exporter dxl script is fixed.
