Before, you'd get an error like:
```
EXCEPTION: Cannot find a differ supporting object ‘[object Object]’ in [users in UsersCmp@2:14]
```
Now, you get:
```
EXCEPTION: Cannot find a differ supporting object ‘[object Object]’ of type 'Object'. Did you mean to bind ngFor to an Array? in [users in UsersCmp@2:14]
```
Now, using `ng.probe(element)` in the browser console returns
a DebugElement when in dev mode.
`ComponentFixture#debugElement` also returns a new DebugElement.
Breaking Change:
This is a breaking change for unit tests. The API for the DebugElement
has changed. Now, there is a DebugElement or DebugNode for every node
in the DOM, not only nodes with an ElementRef. `componentViewChildren` is
removed, and `childNodes` is a list of ElementNodes corresponding to every
child in the DOM. `query` no longer takes a scope parameter, since
the entire rendered DOM is included in the `childNodes`.
Before:
```
componentFixture.debugElement.componentViewChildren[0];
```
After
```
// Depending on the DOM structure of your component, the
// index may have changed or the first component child
// may be a sub-child.
componentFixture.debugElement.children[0];
```
Before:
```
debugElement.query(By.css('div'), Scope.all());
```
After:
```
debugElement.query(By.css('div'));
```
Before:
```
componentFixture.debugElement.elementRef;
```
After:
```
componentFixture.elementRef;
```
BREAKING CHANGE:
- Platform pipes can only contain types and arrays of types,
but no bindings any more.
- When using transformers, platform pipes need to be specified explicitly
in the pubspec.yaml via the new config option
`platform_pipes`.
- `Compiler.compileInHost` now returns a `HostViewFactoryRef`
- Component view is not yet created when component constructor is called.
-> use `onInit` lifecycle callback to access the view of a component
- `ViewRef#setLocal` has been moved to new type `EmbeddedViewRef`
- `internalView` is gone, use `EmbeddedViewRef.rootNodes` to access
the root nodes of an embedded view
- `renderer.setElementProperty`, `..setElementStyle`, `..setElementAttribute` now
take a native element instead of an ElementRef
- `Renderer` interface now operates on plain native nodes,
instead of `RenderElementRef`s or `RenderViewRef`s
Closes#5993
Change beforeEachBindings to beforeEachProviders but preserve the
@deprecated method beforeEachBindings, in order to keep a working
deprecation warning
BREAKING CHANGE
Before
import * as p from 'angular2/profile';
import * as t from 'angular2/tools';
After
import * as p from 'angular2/instrumentation';
import * as t from 'angular2/platform/browser';
All common directives, forms, and pipes have been moved out of angular2/core,
but we kept reexporting them to make transition easier.
This commit removes the reexports.
BREAKING CHANGE
Before
import {NgIf} from 'angular2/core';
After
import {NgIf} from 'angular2/common';
Closes#5362
This is part of ongoing work to make core platform-independent.
BREAKING CHANGE
All private exports from 'angular2/src/core/facade/{lang,collection,exception_handler}' should be replaced with 'angular2/src/facade/{lang,collection,exception_handler}'.
BREAKING CHANGE
All private exports from 'angular2/src/core/{directives,pipes,forms}' should be replaced with 'angular2/src/common/{directives,pipes,formis}'
Closes#5153
