I use a simple web application that uses struts2 (view)- tiles (view) – Spring – Hibernate.
It is working fine. I have a strange behavior explained below.
1. Consider I have form. I fill up the text boxes, select boxes and press Submit. The values are getting displayed. Perfect!
2. If I go to any other page and coming to the previous page again. The old values given are still retained by default and results are displayed as per the earlier selection.
3. This condition became worse when I have a try to insert records being fetched in the form. The records are getting duplicated with incremented IDs in database.
The reason is I dint specify the beans in prototype scope!!
Thanks for coderanch.com forum!
