link-to in integration tests throw: Cannot read property 'applyIntent' of undefined

[rwjblue]

The following error occurs on canary (but works properly on prior releases) for this test:

The test is attempting to ensure that a component integration test is capable of rendering a {{link-to}} even when the router is not booted/available.

I suspect it was caused by one of the following PR's which have changed things in the routing and/or link-to area:

• remove routeArgs #15788
• cleanup active computed property #15779
• make sure _isActive returns boolean in link-to #15762
• [BUGFIX beta] reuse extractQueryParamsArgument #15811

@bekzod - Would you mind taking a look at this? This is exactly the scenario (e.g. {{link-to without routing) that I was referring to in https://github.com/emberjs/ember.js/pull/15779/files#r148964352...

@rwjblue sure I am looking

@rwjblue sorry couldn't resolve this, dug a bit found inline link-to is ignoring first positional param
when didReceiveAttrs called params has index parameter only when Hi index passed https://github.com/emberjs/ember.js/find/master#L815 ,
I suspect it something to do with transform-inline-link https://github.com/emberjs/ember.js/blob/master/packages/ember-template-compiler/lib/plugins/transform-inline-link-to.js which is unfamiliar zone for me :)

Hmm. I didn’t think the issue was only for inline link-to. I’ll test though.

Can confirm this.

I didn’t think the issue was only for inline link-to. I’ll test though.

This as well: happens for inline as well as block form of link-to!
