ReactDOM.render(<MyComponent />, container)

get error:

Uncaught TypeError: Cannot set property 'parentContext' of undefined

function initVcomponent(vcomponent, parentContext, namespaceURI) {
        var Component = vcomponent.type;
        var props = vcomponent.props;
        var uid = vcomponent.uid;

        var componentContext = getContextByTypes(parentContext, Component.contextTypes);
        var component = new Component(props, componentContext);
        var updater = component.$updater;
        var cache = component.$cache;
            // cache is undefined!
        cache.parentContext = parentContext;

Can you add a simple demo for producing this problem?

Something maybe relate with it. if you use babel6 to transform es2015 classes and run in IE9/10, there is a trouble super constructor would not be calling.

I use babel6 to transform es2015 classes, but I run code in chrome 52.

@Lucifier129 you are right. I removed es6 class syntax and the error gone.

However, it's disappointed if not support class feature...

FYI #75
