Synthetic Events get lost through an Action

I have a Store Action that gets triggered on an input field onChange (it’s a type="file" input), I need the event in order to get the target’s values, but triggering a Store Action on onChange gets the event killed on the way.

warning.js:36 Warning: This synthetic event is reused for performance reasons. If you're seeing this, you're accessing the property `target` on a released/nullified synthetic event. This is set to null. If you must keep the original synthetic event around, use event.persist().

Shouldn’t actions be synchronous operation? Unless specified otherwise?

My general thoughts on bumping major version is that you should have a pretty good reason to do so, because anytime you do something backward-breaking like that you tick off a number of people that don’t like change. So the benefit of the backward-breaking change has to outweigh its own cost.

Been debating on whether this sync change balances that equation or not.

…though eek’s point about redux users is a good one…I think that tips scales enough to be worth the major change.

I’ll start looking at what might need to be done to make actions sync by default (except for actions with child-actions).

Well, the store is automatically created during componentWillMount.

So there’s two main options. Move your action call after that, or create your store before that.

So you could do your action call in the componentWillMount, after you super call. Or do it async to push the action to the event loop like you were doing (though, like I said…be careful with that…I don’t think there’s any reason React couldn’t one day just make there be time between constructor and mount, in which case that would make a race issue).

Or, (I think) the more elegant way to do things, if you know you’re gonna use actions before components mount, then you can just not wait for the store to be made automatically, and call Reflux.initStore(MyStoreClass);. You can probably just put it at the end of the store class itself.
