Mandatory property for DialogField

Usually in Dialog Forms it's unable to set mandatory property for Dialog Fields. The lack of this property sometimes annoyed me. At the end I've decided to eliminate this gap :-) To expand the standard functionality you need to do the following steps: 1.Add mandatory() method into DialogField class:

void mandatory(boolean r)
{
    str name;

    // If properties exists then we are on server
    if (properties)
    {
        name = #Propertymandatory;
        if (! properties.exists(name))
            properties.add(name,true);
        properties.value(name,r);
    }
    else
        this.fieldControl().mandatory(r);
}

2. Add into unpack() method following lines:

case #PropertyMandatory:

        this.mandatory(unpackedProperties.valueIndex(i));
break;

Now you may enjoy mandatory property in Dialog Forms. This trick published in Axaptapedia too.
