Dynamically initialize the multi-select options

[ShaneZhengNZ]

Look at the multi-select demo examples, all the them have the select options initialised.

In my case, I want to load the HTML and then call the http service to initialise the selection options, which gives me the $select.selected is undefined error.

To workaround that problem, I have to manually initialize the option to an empty array, then get the http service to load the data.

Example in plunker - http://plnkr.co/edit/F0jCYug8MQuV1tXU4jlX?p=preview
For the example, in the script.js file, if you comment out link 45, the multi-select won't work.

My request is whether ui-select should initialise the options to an empty array automatically in the case of multi-select, so we don't need to manually do that.

Is it not related to this issue? #404 Fix might be soon available. #256

+1 I don't think #256 will fix this

I have the same problem with the https://github.com/owncloud/tasks app for owncloud:
https://github.com/owncloud/tasks/blob/c9885510f491423bbc3d6e6aa0f79b414d6686e4/js/app/controllers/detailscontroller.coffee#L53-L58

Would be great if this could be resolved. Thanks for your work anyway!
