No provider for Params


  • Hello,

    I am migrating my app from Ionic to Onsen (2.0.3, angular=2.1.2, router=3.1.2, angular2-onsenui=1.0.0-rc.1) and I am getting “No provider for Params” if I try to inject Params into the component. I tried to add “providers: [Params]”, but in that case I am getting an “Can’t resolve all parameters for Params” error. Do you have any recommendations how to move forward? Maybe it’s a wrong way to get navigator parameters or using mismatching Onsen/Angular/Bindings versions?

  • I was trying to figure out the cause by using kitchensink sample (https://github.com/OnsenUI/angular2-onsenui-kitchensink).

    Params are injected in Dialog.ts and they work as expected, but if I add the same constructor:

      constructor(params: Params) {
  }

    to, for example, Forms.ts, it fails with the same error:

    core.umd.js:3004
EXCEPTION: Uncaught (in promise): Error: Error in ./Forms class Forms_Host - inline template:0:0 caused by:
No provider for Params!
Error: No provider for Params!
at NoProviderError.BaseError [as constructor] (http://localhost:3000/vendor.bundle.js:1118:39)

    I still can not find any differences between these two components. Any recommendations?

    UPDATE 1: As I understand, TempDialog component is not displayed directly as Forms or Dialogs components, and it is “pushable-only page”.
