RLS in display methods on reports (AX 4.0)

X++ select statements do ignore Record Level Security (RLS) by default. With the property  recordLevelSecurity the behaviour to use Record Level Security can be modified. The property can also be used to retrieve the current behaviour.

But there is a difference to select statements inside display methods. Every select statement has activated Record Level Security if the command is in a scope inside a call stack with a display method root. But the current status is not really available trough the property recordLevelsSecurity. A call to this propery will return false, make you thinking Record Level Security is off - but it is not.

display showEmplName()
{
    EmplTable emplTable;
    EmplName name;
    ;
    info(strfmt("%1", emplTable.recordLevelSecurity())); // this will return false, but actually it's true!

    select firstonly Name from emplTable 
        where emplTable.EmplId == reportTable.emplId; // the record will use RLS (yeah, it's magic)

name = emplTable.Name;

    return name;
}

Even here the Record Level Security is on, without explicit change to recordLevelSecurity property:

display showEmplName()
{
    EmplName name;
    ;
    name = EmplTable::find(reportTable.EmplId); // the select inside the find method will use RLS even you haven't activate this

    return name;
}

If you want to ensure, that Record Level Security is really off, you need to touch the property explicit.

display showEmplName()
{
    EmplTable emplTable;
    EmplName name;
    ;
    emplTable.recordLevelSecurity(false); // this will really free from RLS   

    select firstonly Name from emplTable 
        where emplTable.EmplId == reportTable.emplId;

    name = emplTable.Name;

    return name;
}

This Problem appears in AX 4.0. In AX 2009 this phenomen does not exists; Record Level Security stays off until you change it explicit.
