Problems with property opened in Angular Material --> sidenav

[ADominguezes]

I've a problem with sidenav, with the property "opened" of md-sidenav

I've this code:

<md-sidenav #sidenav mode="side" class="app-sidenav" opened="true">
    ...
</md-sidenav>

When I refresh the page, sidenav is open and it's ok, but when I click in the button for close sidenav, I've the next errors in console:

error_handler.js:45 EXCEPTION: Uncaught (in promise): undefined
error_handler.js:50 ORIGINAL STACKTRACE:

My version of Angular Material is: 2.0.0-alpha.9
My version of Sidenav is: 2.0.0-alpha.8-2

As of 2.0.0-alpha.9 there is only a single package called @angular/material
you can uninstall all @angular2-material/* packages, as all controls are now in @angular/material.

Note: also, update your NgModule to only reference MaterialModule / MaterialModule.forRoot()

Ammm!! ok thank you I didn't know. ;)
The problem with sidenav continues.

Experiencing the same issue. Happens only once, the first time you trigger a change in state (open/close).

[ADominguezes]

Yes it's true, the error shows only the first time

Experienced the same issue on material 9-3. Any resolution for this?

Hi Guys, I any news please, did someone solve this issue?

[omararturo]

Hi,
This is the temporal solution:

import { Component, OnInit, ViewChild } from '@angular/core';
import { MeteorComponent } from 'angular2-meteor';
import { MdSidenav } from '@angular/material';

import template from './app.component.html';

@Component({
    selector: 'app',
    template
})
export class AppComponent extends MeteorComponent implements OnInit {

    @ViewChild('sidenav') sidenav: MdSidenav;

    constructor(
    ) { 
        super();
    }

    ngOnInit(): void {
        this.sidenav._onTransitionEnd = function () {            
            this._openPromise = null;
            this._closePromise = null;
        }
    }
}

I hope it will be helpful to you.

@mmalerba can you confirm that this is fixed in master?

[mmalerba]

Yup, I can repro it in the plunker template but not in master, so seems like it's fixed.

[leocaseiro]

I confim the error still happening with @angular/material@2.0.0-alpha.10

The fix from @omararturo works temporary for me.

PS: I reported detail about this error here: #1382 (comment)
