jQuery Forum

I'm using select2 and I have this code:

And when I click in select to expand, works well but any other click more in any page element return a javascript error:

    Uncaught SyntaxError: Invalid regular expression: /(^|\.)s2id_options_values[code][estado-de-conservacion](\.|$)/: Range out of order in character class

This error is returned by jQuery v2.0.3

The problem seems to be in "-" sign, because other select with same structure but without "-" are working well.

At first I send this issue to select2, but they say that is a jQuery error (https://github.com/ivaynberg/select2/issues/1841)

Here a JSFiddle example http://jsfiddle.net/nzt7g/1/
