This was really strange (but funny) issue!!
I created few of the InfoPath Forms and published them into the SharePoint 2010 Library.
After a while, I got a request from another Developer asking me for the forms as they wanted to update and make few changes into the existing form. (So I did give them the forms 😛 )
After a while they come running to me and said that they are getting an error while opening the form and below is the error:
“This form cannot be opened because it requires the domain permission level and it currently has restricted permission.”
And another error:
“Forms that require the domain permission level contain features that access information on a network, such as data connections, linked images, and code.”
Can’t a developer just edit the InfoPath form of an another Developer?!?!
I asked the developer to send me the list of steps he is following while trying to open the file (and that’s the catch).
What he was trying is “Double-click on the form to open it?!?!?!?!”
Solution: Right Click on the form and Select “Design” 🙂
Have fun & Enjoy!!
