Question is rather if that still makes sense to support that and as far as I can see it should be trivial to reinitialize the object. </blockquote> Hi Daniel Rakos, Could you give a comment on this question? Is it necessary to support timeline reset interface? I only see the timeline value can be changed by signal operations in Spec. Thanks, David Zhou </body> </html>
