I've just recently encountered a weird error / bug in SharePoint. Here is the scenario:
I have a custom column "Test Date" that is of DateTime field type. The field is configured as required.
It is added to a custom Content Type "Test CT" that is based on a "Publishing Page" content type
I have created a Page Layout "Test PL" which is based on that particular content type.
Now here is what happens:
I try to create a page based on both that Content Type and Page Layout in the Pages Library. I manage to create it successfully.
However, when I go to try and edit the page, fill-in the required values and try to save it using the PAGE tab -> Save button, I get the below error/s. Note that this happens no matter what I choose in the drop-down menu for Save Button.
The file XXX has been modified by user on date
But I know I am the ONLY user modifying the page.
If I try to save again it gives me options to whether Discard my Changes, Keep Editing, Overwrite Changes, or Merge.
- However, if I use the Save button on the upper right corner of the screen (the shortcut). I am able to save successfully without any errors!
The only thing I've tried that made it work was if I made the DateTime optional. But I need it to be required.
Is there any workaround to this error / bug?
