I am trying to render "OTHERPAGE" when a user clicks the back button ... snippet:

onClickBack:function(e){
    var parentId = getParentIdById(this.props.id);
    React.render(<OTHERPAGE id={parentId} />, document.getElementById('main'));
},

the function triggers as i expect it. getParentIdById returns the UUID as a string, just how I need it. calling React.render throws an exception:

message:"element.type is not a constructor"

I dont get it... I required React on top of the page:

var React = require('react');

does anyone know what the problem could be here?

Thanks for helping

EDIT:

I also get this warning:

"Warning: Only functions or strings can be mounted as React ponents."

Doesn't really help me though...

• 2 My guess is OTHERPAGE isn't what you think it is. What's the output of console.log(OTHERPAGE)? – Michelle Tilley Commented Nov 29, 2014 at 22:38
• I think you are right... it returned "Object { }" instead of "function OTHERPAGE(config, children)" ... but why? – Max Bumaye Commented Nov 29, 2014 at 22:42
• Max, that's outside the scope of the information you've given. – Brigand Commented Nov 29, 2014 at 23:17
• Yes @FakeRainBrigand I fear it is. I was hoping that it was some kind of mon issue... I am trying to restructure using react-router – Max Bumaye Commented Nov 30, 2014 at 0:05
• Did you ever resolve this issue? I'm having the exact same error. – Lee Commented Jan 6, 2015 at 15:57

You have to export the OTHERPAGE from it's file:

file OTHERPAGE.react.js:

var OTHERPAGE = React.createClass({...});
module.exports = OTHERPAGE;

use the OTHERPAGE ponent:

var OTHERPAGE = require('./ponents/OTHERPAGE.react');
var React = require('react');

var parentId = ...;
React.render(<OTHERPAGE id={parentId} />, document.getElementById('main'));
