Sample weights / complex study designs

Hi all,

I'm wondering what is the proper way to do sample weights in OpenMx >2.0? I found this old thread with an example that uses mxFIMLObjective, but mxFIMLObjective looks to be deprecated. Any help with a working example would be much appreciated!

Also, this way of doing weights by nesting mxModels seems pretty cumbersome -- is there an updated interface or a way to "tack on" weights to an existing model definition? (Ideally I'd like a way for models to be easy to run with and without weights).
