I am attempting to use aurelia-dialog to open a popup from my main view model.

When I try to use: this.dialogService.open, I get the following error:

aurelia-dialog.js:292 Uncaught TypeError: Cannot read property 'createChild' of undefined
    at DialogService.open (VM189 entry-bundle.js:18912)
    at Customer.open_consolidations (VM189 entry-bundle.js:199)
    at CallScope.evaluate (VM189 entry-bundle.js:13641)
    at Listener.callSource (VM189 entry-bundle.js:17370)
    at Listener.handleEvent (VM189 entry-bundle.js:17379)
    at DelegateHandlerEntry.handleEvent (VM189 entry-bundle.js:15441)

I have created a gist to show my error:

Any insight is appreciated.

I’ve played a little bit with you gist, but didn’t find the reason for the error.

but just as an FYI: you use querySelector to get a reference to a div in the view.
you should use ref instead.
also: if you use aurelia correctly - you should not have the need for JQuery at all…

There are many mistakes in your code.

  1. the usage of dependency injection in constructor is wrong. The component should not create an instance of a class by itself, that’s the very reason of using depedency injection (acquire dependency from outside, not creating).
  2. missing dependency DialogController in the dialog js code.
  3. missing dom <ux-dialog> in dialog html code, wrong tag <ux-dialog-head>, it’s <ux-dialog-header>, and you have no local style.css.
  4. <title></title> would not work, title is a special tag name used in html head section, it’s by default not displayed when using in html body section.

Thank you for your fixes. I am now moving this stuff into my app, and hopefully it goes well.
