[Question]Develop new feature

[anhntbk08]

Hi,

Thank for your great lib, it's very useful. I got a question on developing new feature.
I forked the code and make some changes, rebuild and refer it to my code, it keeps saying
" Element ref was specified as a string (browser) but no owner was set. You may have multiple copies of React loaded. (details: https://fb.me/react-refs-must-have-owner). "
Can you give me some advices to solve this problem.

Regards.

Hi Tuan,

If you used npm link or yarn link with your project where react-keyed-file-browser is used make sure that you only have a single node_modules directory from the project you're transpiling (assuming you're using webpack). If a node_modules directory exists within any of your sub-directories it might be picking up that version of react as well.

Alternatively it could be a usage of ref in browser.js or table.js
Change ref="newName" to "ref={el => { this.refs.newName = el }}andref="browser" to "ref={el => { this.refs.browser = el }}

As some of the code we use hasn't been updated in a while we haven't moved everything to the new react ref style.

Hope this helps.
