This needs to be fixed ASAP, it's causing isues when the report page is being destroyed.

Hello Andrew,

Thank you for the provided information about the issue!

This is a known problem and there is an already existing public item for it - perspectiveManager.dispose is not a function error in Angular viewer.

I am afraid there is no workaround with the Angular report viewer because the issue occurs when the viewer component is destroyed on the ngOnDestroy event and that cannot be disabled:

However, you may try to integrate the HTML5 Report Viewer in the Angular application instead. For details on how to do that, you may have a look at the Displaying the Web Report Designer in Angular application - Telerik Reporting KB article and follow the steps that are related to the viewer component.

I hope that this will help. Please let me know if you have any questions.

Regards,
Dimitar
