* v3.20.2...v3.24.0 * Fix handle undefined outlet in route component * Don't use template helper for optional modal.open Using the optional-helper here will trigger a computation in the same runloop error. This is because we are setting the `modal`-property when the `<Ref>` component gets rendered which will update the `this.modal`-property which will then recompute the `optional`-helper leading to this error. Instead we will create an action that will call the `open`-method on the modal when it is defined. This gets rid of the double computation error as we will not access the modal property twice in the same runloop when `modal` is getting set. * Fix - fn needs to be passed function tab-nav We create functions in the component file instead so that fn-helper stops complaining about the need to pass a function. * Update ember-exam to 6.1 version "Makes it compatible" with ember-qunit v5 * scheduleOnce setMaxHeight paged-collection We need to schedule to get around double-computation error. * Fix - model.data is removed from ember-data This has been private API all along - we need to work around the removal. Reference: https://github.com/emberjs/data/pull/7338/files#diff-9a8746fc5c86fd57e6122f00fef3155f76f0f3003a24b53fb7c4621d95dcd9bfL1310 * Fix `propContains` instead of `deepEqual` policy Recent model.data works differently than iterating attributes. We use `propContains` instead of `deepEqual`. We are only interested in the properties we assert against and match the previous behavior with this change. * Fix `propContains` instead of `deepEqual` token * Better handling single-records repo test-helper `model.data` has been removed we need to handle proxies and model instances differently. * Fix remaining repository tests with propContains We don't want to match entire objects - we don't care about properties we haven't defined in the assertion. * Don't use template helper for optional modal.open Using a template helper will give us a recomputation error - we work around it by creating an explicit action on the component instead. * Await `I $verb the $pageObject object` step * Fix no more customization ember-can No need to customize, the helper handles destruction fine on its own. * Fix - don't pass `optional` functions to fn We will declare the functions on the component instead. This gives us the same behavior but no error from `fn`, which expects a function to be passed. * Fix - handle `undefined` state on validate modifier StateChart can yield out an undefined `state` we need to handle that in the validate modifier * Fix linting errors tests directory * Warn / turn off new ember linting issues We will tackle them one by one and don't want to autofix issues that could be dangerous to auto-fix. * Auto-fix linting issues * More linting configuration * Fix remaining linting issues * Fix linting issues new files after rebase * ui: Remove ember-cli-uglify config now we are using terser (#14574) Co-authored-by: John Cowen <johncowen@users.noreply.github.com> |

# StateMachine
```hbs
<StateMachine
@chart={{xstateStateChartObject}}
as |fsm|>
</StateMachine>
```
`<StateMachine />` is a renderless component that eases rendering of different states
from within templates using XState State Machine and Statechart objects.
**Please note**: This component is currently a gradual replacement for
StateChart, which has a less ergonmic interface. Guard and Action component are
currently omitted due to a preference to use entries to define those instead of
components (which is WIP)
### Arguments
| Argument/Attribute | Type | Default | Description |
| --- | --- | --- | --- |
| `chart` | `object` | | An xstate statechart/state machine object |
| `initial` | `String` | The initial value of the state chart itself | The initial state of the machine/chart (defaults to whatever is defined on the object itself) |
The component currently yields 1 contextual components:
- `<fsm.State />`: Used for rendering matching certain states ([also see State Component](../state/README.mdx))
and 2 further objects:
- `fsm.dispatch`: An action to dispatch an xstate event
- `fsm.state`: The state object itself for usage in the `state-matches` helper
### Example
```hbs
<StateMachine
@chart={{xstateStateChartObject}}
as |fsm|>
<fsm.State @matches="idle">
Currently Idle
</fsm.State>
<fsm.State @matches="loading">
Currently Loading
</fsm.State>
<fsm.State @matches={{array 'loading' 'idle'}}>
Idle and loading
<button disabled={{state-matches fsm.state "loading"}} onclick={{action fsm.dispatch "START"}}>Load</button>
</fsm.State>
</StateMachine>
```
