I upgraded my React version from 0.12.2 to 0.13.2 and my React-Router from 0.12.4 to 0.13.2. Doing just those two upgrades and nothing else, I now get the following error when I load my webpage/app:
Uncaught TypeError: Cannot read property '_currentElement' of null
Any ideas what might be causing this? I have seem some references to a potential React-Router bug, but nothing definitive.
The specific line that causes the error is:
ReactRef.detachRefs(internalInstance, internalInstance._currentElement);
Update 1: I also just upgraded reactify from version 1.0.0 to 1.1.0 and react-router-bootstrap (which I'm not actually using yet) from 0.9.1 to 0.13.0 based on @BinaryMuse's comments - no change.
Update 2: After further testing, I have narrowed this down to an issue with react-d3. Disabling the react-d3 code from my site causes the error to go away. I am removing the routing code to make the post more concise since I am now fairly confident that react-router is not causing this issue.
Update 3: Thanks to @CoryDanielson for creating the new tag for react-d3.
