This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
I have left and right pane in my screen. Left will have a tree and clicking the tree will show a form in the right side pane. I have few mandatory fields in my form.
The problem I face is, if I submit the form with some mandatory fields empty. I am getting validation error with required message as expected.
The strange behavior is, when i click on the left side tree link to populate values in the form after getting validation problem. Only those fields which failed validation gets updated with proper values leaving the values which we entered in mandatory fields unchanged.
I will give an example to make you better understand.
1. Consider the left side tree has a list of students and right side form has First name and Last name.
2. If you try to add/modify a student with empty Last name, you will get "Last name required" message.
3. Now if you try to click on a different student from the tree, only Last name which had a validation problem previously will be properly populated and First name will always be the same which was there during the validation problem.
Please let me know what I should do solve this issue. This is becoming critical to solve day by day.
