It seems like siteDataServices hasn't been created at the time the
SMDelegate constructor is being called. You'll need to dig through
your code to find out why, e.g. check where you're calling
ReviewKeywordsCommand(), and possibly call the constructor at some
other point when you know the remote object has been created.
Regarding parameter passing, the constructor example you gave is
exactly what I had in mind. The value you're passing isn't a string
though, it's a reference to the RemoteObject that you gave the id
"siteDataServices" to. Personally, I'd probably pass the service as a
parameter, but as long as the delegate constructor is called only
after you know the service object exists, either way should work.
I hope this helps, and another thing to note is that the work you're
doing now to implement these design patterns will pay off down the
road - especially if you're implementing a large-scale app.
