Hi, Jane
This is a master-detail project, please see the shot.
First step, I create a new master record, which has masterkey1, S015, and masterkey2, 2009/6/2
Then, I enter detail page to add records.
But, I don't save it and I go back to master page using browser's forward button.
Yes, I never know why users do like this. <img src='https://asprunner.com/forums/file.php?topicimage=1&fieldname=question&id=11966&image=2&table=forumtopics' class='bbc_emoticon' alt=':ph34r:' />
If user's mouse cursor moves to another record on list page, maybe he is not just on purpose.
And go to detail add page using backward button of browser.
OK, I enter data on detail add page. The masterkey2 is still 2009/6/2.
When I enter save, the masterkey2 changes into 2009/4/8.
Then, I go back using back button
This is last shot, the record is added to last master record, not current one.
I hope everyone could understand what I talk about.
Please give me some ideas or thoughts. Thanks!
