`void-dom-elements-no-children` checking every .createElement and crashing

[daltones]

I've just updated to v6.10.0 and enabled void-dom-elements-no-children.

It's crashing with this error:

TypeError: Cannot read property 'properties' of undefined
    at EventEmitter.CallExpression ([...]/eslint-plugin-react/lib/rules/void-dom-elements-no-children.js:121:28)
[...]

It happens with this simple code:

document.createElement('img');

So here is the first problem:

• The rule thinks that every .createElement( is the React.createElement.

Now testing with the actual React:

import React from 'react';

React.createElement('img');

The rule will crash too.

Second problem:

• The rule doesn't treat incomplete number of createElement's arguments (as while typing React.createElement()).

The first problem is intentional, as it looks for anything that could be a createElement call first, then refines.

The second is clearly a bug.

[daltones]

Okay, but what is the point of the first problem being intentional when document.createElement could be a trivial false positive?

Why can't it work same way as other rules that use pragma setting to verify React.(createClass|(Pure)?Component)?

[daltones]

Oh, right, I missed something. Fixing the second problem would not warn about document.createElement('img').

But maybe first problem could turn into another issue to prevent some edge cases like objectNothingAboutReact.createElement('img', {foo: bar}, 'baz').

Thanks!

I believe that if the bug was fixed, only React createElement calls would be matched.

I just installed master in one of my projects, and I'm no longer getting the TypeError: Cannot read property 'properties' of undefined error. So #1080 fixed that, which solved my problem. Thanks @jomasti.
