I've deployed SharePoint Foundation 2013.

Some information about our SharePoint system:

I have 3 server for serving this Sharepoint

  • ServerA: Sharepoint foundation 2013 version 15.0.4569.1506
  • ServerB: SQL server 2012 developer
  • ServerC: OWA

I'm facing the problem is while input data to task list the loading icon keep loading... When I press f5 or click other page the text "hi" will be lost (see the image below)

Image 1

I debug on browser it show me error: Uncaught TypeError: Cannot read property 'ID' of undefined Error

How can I workaround this problem? Anyone can help?

Many thanks

Specify columns & also add it to view :

Enter '0' in Percent complete. Predecessors column is optional.
