createContainer and child components

Hello,

I’m developing a React + Meteor app.

I have a route that accepts a parameter for example to show the single page of a document, so the route accepts an ID parameter. Then the route forwards the request to:

  • createContainer component that gets the data from collection (based on id) and return the document to a child component

  • child component displays data

Now, in my child component, I want to setup state in the constructor based on the value from the data (document), but the value of the data is stil undefined in the constructor, is this normal? How can I setup state based on value of data?

Thanks.
