How to refresh task hierarchy after creating some tasks programmatically?

Hi,

How can I get the left task hierarchy (or tree) get refreshed with new tasks which are created by myself programmatically in cPro 4.5?

I created some tasks under the exising task but they are not shown in the left task hierarchy automatically, only shown after I refresh the page manually or by re-entering the project again.

Thanks in advance for your help. Any suggestion would be helpful.

Best regards,

Beiyang
