JSON is undefined. Infopath Form People Picker in SharePoint 2013
After some analysis, we found that, this is a known defect with the Microsoft and it is being fixed on the subsequent Knowledge Bases. http://support.microsoft.com/en-us/kb/2880473 But even, then there are many information revolving around this error like, whether this is fixed on the April CU or March CU etc., We don’t want to take any assumptions as this is been an existing system.
Hence, we wanted to fix this by the coding level. Actually the fix was very simple, but it requires an update on the Layouts File. (Which many customers may hesitate, but there is no harm in it)
Open the PeopleDialog.master from the Layouts Folder.
C:\Program Files\Common Files\microsoft shared\Web Server Extensions\15\TEMPLATE\LAYOUTS
1. Add the DocType at the top of the File.<!DOCTYPE html>
2. Update the Line <meta http-equiv="X-UA-Compatible" content="IE=10"/> with <meta http-equiv="X-UA-Compatible" content="IE=edge;chrome=1" />
The Updated file looks like below. The same can be copied and pasted.
