Hello Jorge,

Utilize the ExpandSharedProperties method of the UpdateContext class.

You would do this when you use your property within the prepare, execute, cleanup, or rollback methods.

For example, to use your FolderKey2 property in the execute method, you could expand any shared properties in the value by doing this:

public override void Execute(UpdateContext context) {

   string expandedFolderKey2 = context.ExpandSharedProperties(this.FolderKey2);

   ...

[Description("Type the name of the system folder($FolderSis)")]
        public string FolderKey2
        {
            get { return  this.Folder2; }
            set
            {
                this.Folder2 = value;               
            }
        }

Hello Jorge,

We place the icon on our action editors to indicate that the field supports expanding shared properties.  On your actions, you decide which properties support expanding shared properties.  The default editor for a custom property is a property grid.  If you choose to, you can create an editor for your action and add the blue ball icon.
