React 15 regression: controlled select elements with optgroup not displaying value on initial render

[mavisd]

Using React 15.0.1, controlled select elements with optgroup elements are not displaying (selecting) the value provided on initial render. See the following jsfiddle for a simple test case:

Here is another fiddle where it is working using React 0.14.8:

Could you try setting bind() in your render method? The SO questions and replies should give you a indication of how you would do that.

@mavisd I've been seeing the same behaviour in my React 15.0.1 app too.
For the moment I've been falling back to setting the selected attribute on the selected option tag (which does trigger the React warning about using the defaultValue or value on the select instead)

@ev1stensberg

bind() is not necessary with React.createClass() as the methods are autobound. Also the code is identical but behaves differently in different versions, so it’s an indication that it might be React’s fault.

I think this is the same as #6440 and #6434, and was fixed in #6442. The fix is not out in 15.0.1, but it should get into the next patch release. I can confirm this working with the build from the master:

I’m closing for this reason.
