Error description

  • Repeatedly changing open mode of module with differing display
    state using DXL leads to diagnostic logs
    
    Steps to reproduce:
    - Create a module with few objects
    - Set the module for sharing
    - Open the module and run the script below:
    -----------------------
    string sPath = fullName(current Module)
    Module mod
    int i = 100
    while (i-- ? 0) {
            print i ', '
            mod = share(sPath, false)
            Object obj
            for obj in mod do break
            if (canLock(obj)) {
                    lock(obj) // (Line 11)
            }
            downgrade(mod)
    }
    -----------------------
    
    DOORS crashes with diagnostic logs.
    
    Work-around:
    Maintain consistency of display state. For example, if while
    using share() perm, display parameter is set to false, even
    while using downgrade(), ensure display parameter is set to
    false
