Hi lhor,
I can see "Page Show" event is fired once in master-detail page. Also, I want to do something to initial the detail page when the detail page is loaded or showed. I can't trigger the action in detail page from the master-detail page.
Thanks for your information. Unfortunately, the tutorial is based on REST API of PayPal. Is there any tutorial for PayPal integration based on classic API or plugin?
BR,
Peter
