Current behavior

An Angular application cannot be compiled in the AoT mode with the --fullTemplateTypeCheck option if Kendo UI for Angular Buttons are used.

ERROR in node_modules/@progress/kendo-angular-buttons/dist/es/splitbutton/splitbutton.component.d.ts.SplitButtonComponent.html(35,17): : Property 'keyDownHandler' is protected and only accessible within class 'ListButton' and its subclasses.

Expected behavior

The application is successfully compiled in the AoT mode with the --fullTemplateTypeCheck option if Kendo UI for Angular Buttons are used.

Please, pay attention that the same issue can be also reproducible with other Kendo packages. I apologize for not being able to verify them now.

Thanks for the report. We managed to address the issue in question. The latest version of buttons package should contain the fix.
