Current behavior
When using runGuardsAndResolvers: 'paramsOrQueryParamsChange' to make sure that a resolver is run whenever a query parameter changes, the resolver does runs, but the fetched data is not passed onto the subscription to the route.data Observable within the component.

Expected behavior
If I subscribe to route.data within the component, I would expect to get updates whenever new data is fetched, but I only get the initial data, no updates.

Please tell us about your environment:
Ubuntu 16.04

• Angular version: 2.0.X
  Angular 4.0.0-rc.5

• Browser:
  Chrome 54

Can you reproduce in a plunkr please

@Toxicable I'm sorry I'm afraid that I am not really familiar with plunker and fiddling around with it to create an angular4.0.0-rc.5 setup will simply take too much time, that I don't have right now. But I created a sample app with angular-cli and moved it to my github: https://github.com/basilikum/bug15290_ng4

It is very straight forward: the link "change query param" changes the query param i, to the current value of item (which is the big letter number on screen). Then the resolver kicks in and resolves item to a new random number. But as you can see, the number is never updated, despite the fact, the the resolver actually runs.

@basilikum here's a template plunkr for v4

@Toxicable Sorry I could not get it to run within plunker. Probably just a small mistake but I have to look into it but currently not time. I can try to get the plunker demo to run within the next 2 days or so but probably not before that. Sorry again. Does the github repo not help?

[Toxicable]

I didn't try your github repo but it works fine in this plunkr

So looks like something wrong with the way you're testing it possibly, or maybe your setup

[basilikum]

@Toxicable Hmm...but your plunker does not even change the query params in the url? Still does not seem to work for me in this example: http://plnkr.co/edit/UC39EjWv261lnbGMxVqT?p=preview
If you click on the link, it changes the query param and should therefore update with a new random number, which it does not.
You can also see that in the console. The "resolve" log will be executed, but not the "in subscribe" log.

[Toxicable]

@basilikum Right, sorry I see what you're saying. Okay well i'm not sure what's up in this case then

[basilikum]

@Toxicable Ok, thank you anyway. Especially for the help with plunker.
