Upgrade to 2018 R3 issue

[David]

Hi
I'm trying to upgrade my progress controls to 2018 R3 from 2018 R1.  I am using Angular 5.2.3

The issue is the LocalizationService isn’t getting injected into the tootltip directive.  

So this code is failing since localizationService is null 

                this.dynamicRTLSubscription = this.localizationService.changes.subscribe(function(e) {
                    return t.direction = e.rtl ? "rtl" : "ltr"
                })

I noticed on the tooltip samples use Angular 6, so Im not sure if this could be a version issue.  The code worked fine with 2018 R1

Currently I am not immediately planning to upgrade to Angular 6 as I need to make several code modifications for the Rxjs library updates

Any suggestions would be appreciated, thanks

My bad .... the localizationService is defined, however there is no changes property tied to it... the service looks like this:

applicationRef: t {_zone: t, _console: t, _injector: t, _exceptionHandler: t, _componentFactoryResolver: t, …}
componentFactoryResolver: t {_parent: t, _ngModule: t, _factories: Map(15)}
container: null
injector: t {_moduleType: ƒ, _parent: t, _bootstrapComponents: Array(0), _def: {…}, _destroyListeners: Array(0), …}
rootViewContainer: (...)
rootViewContainerNode: (...)

So when it tries to subscribe above, the following error occurs:

ERROR TypeError: Cannot read property 'subscribe' of undefined

Hi David,

In general, the Kendo UI for Angular packages do not follow the R1, R2... release plans, typical for the Kendo UI for jQuery suite, as all of them are separate NPM packages with their own life cycle and versioning. You can check out the latest versions of all packages and the respective major changes/fixes introduces with each version, in the Changes Log section of each package's documentation:

https://www.telerik.com/kendo-angular-ui/components/grid/changelog/

https://www.telerik.com/kendo-angular-ui/components/charts/changelog/

https://www.telerik.com/kendo-angular-ui/components/dropdowns/changelog/ ... etc.

All our packages support both Angular 6 (via rxjs-compat) and Angular 5 (rxjs 5.5+ is still required).

Please make sure that you are using the latest versions of our packages alongside RxJS 5.5+ (remove the package-lock.json file and the node_modules folder and run a clean npm install to ensure the latest versions are actually installed, sometimes cleaning the npm cache also proves necessary).

If the issue persists, can you please provide an isolated runnable project where it can be observed, so we can inspect it further, determine what might be causing it, and suggest a solution or log it for fixing? Thank you in advance.

Thank you Dimiter

Removing the node_modules folder on our build machine fixed it
