Inner exception: System.ArgumentOutOfRangeException

Forms

I have a Forms session (Forms 10.2) that some times users report that they get an error upon submission but from the log I still am unsure of what is causing this error. Is it a field? Is it in my process diagram? I just don't know. Can anyone give me any guidance on this? Thanks!

I think you need to contact your VAR.

Hi Gina,

This issue might happen when FormsAppPool gets recycled when a user is submitting a form.

A temp workaround is set the recycling condition for FormsAppPool to a specific fixed time such as 01:00 which is in the midnight so there is less chance that user will submit a form at that time.

Can you try if this helps?

Ours is already set to 12:00 am and that has not improved this issue. Thanks

Hi Gina,

So this might be a different issue from the known one. Can you open a support case for it? Thanks.

Do we need to have our VAR open a support case on this?

Thanks!

If the issue persists, opening a support case might help resolve it.

Can we open a case or does our VAR need to do that for us?

Hello,

I am also having this issue in Forms version 10.3.1 with a table being populated by a lookup rule. The issue persists when the "Number of rows" setting is set to "Range of rows". The problem goes away when I set it to "Append rows..." setting. However, when I use the Append setting I am unable to remove any populated rows, which is a requirement in the process.

I did not have this issue prior to upgrading to 10.3.1.635.

Thank you and looking forward to a reply.

For us our issue was resolved with the update. We are currently running 10.3.1.635. We have not experienced the issue that Freddie has mentioned. Prior to the update we did double check when the FormsAppPool was set to recycle to make sure it was set to the recommendation listed. That alone did not resolve our issue.
