Ever have issues with losing data when users are filling out really long InfoPath browser based forms? I’ve been meaning to blog about this for ages but haven’t had a chance to. And unfortunately I don’t have screen shots or detailed notes about the error but I’ll try my best to recall.

Scenario: Really long InfoPath forms (taking more than one hour by default) returns a critical error when submitted or when the form tries to retrieve data from the server. The critical error forces you to restart the form and loses all your work in the process.

Solution: As far as I know, the property settings for this has nothing to do with the “Configure InfoPath Forms Services” section of Central Admin > Application Management. Of course not, that would make too much sense. :p

To lengthen this time out setting you’ll want to ‘Configure session state’ from Central Admin > Application Management > Office SharePoint Server Shared Services.

I first found this solution on someone else’s blog but I can’t find it again for the life of me, so kudos to whoever figured this out before me.

Drawbacks? I’m not sure, anybody out there have any ideas how changing the Session State Timeout affects the SharePoint environment?
