Why is the first element always blank in my Rails multi-select, using an embedded array?

Question

I\'m using Rails 3.2.0.rc2. I\'ve got a Model, in which I have a static Array which I\'m offering up through a form such that users may se

Answer 1

I make it work by writing this in the Javascript part of the page:

$("#model_subset_array").val( <%= @model.subset_array %> );

Mine looks more like following:

$("#modela_modelb_ids").val( <%= @modela.modelb_ids %> );

Not sure if this is going to get me headache in the future but now it works fine.
