Hi,
While working with packaged application "Sample Master Detail" in oracle Apex 5.1 I found a weird behavior as top two images. Initially when I run the application in Master detail dash board and try to add milestone in detail part it doesn't allow to add record as Images 1. However, while I go next button and back to previous then the message being changed of the detail (Milestone)
(as image 2 ) then it allow me to add record in detail part. Is it the default behavior of master detail page in IG? If not How to overcome it without having change the next and previous button as there may have only one record and no chance to prev and next.
Thanks,
