Question

I am getting the following error and I don�t know what to do.

Please help. I have a reproducible example after the message.

I am using sun JSF 1.1.01 and Web Logic 8.1.
To reproduce this error
1) Type "testname1" in the Name text field and click the "add name" button.
The form is submitted and the "testname1" is added to the NameList (listbox).
2) Now select "testname1" from the nameList (listbox) and click the "remove name" button.
The form is submitted and the "testname1" item is deleted from the nameList.
So far it working fine. Now
3) Click the "back" button on the browser and click "add name" button.
BOOM, you will get the above mentioned error. I tried many things but not able to figure out the fix is.
Please help.

Answer 1

Hi again,
It seems to solve my issue but I need to press F5 after clicking the button. This button has an action == "cancel" and actionListener method in my bean.
When I press the button the page doesn't refresh as is supposed but if I press f5 it seems like it is when the action "cancel" is being sent. It solved my problem but it didn't.
Frustration
Solved by adding resetActionListener on my cancel button.
