Single line showing as multi line

[Dan Brown2]

Hello,

I have got a String field Medium (100) that has been on a form for while, for some reason it is now showing as a mutli line box.   As far as I am aware nothing has been changed on this field.   I can't find a way to change it back.

In the history of the field, there are 2 Audit Type updates.

Has anyone ever seen this type of behaviour/problem?

Cheers,

Dan

Configure dictionary for the field, and add attribute: is_multi_text=false

is_multi_text true/false String, Wiki, Field List

Thanks for the info on is_multi_text=false! It lead to a really fun discussion on the community stream 2019-01-30.

Ha thanks Chuck for all the coverage in yesterday's stream. Here's a bit more info from ServiceNow related to the occasional occurrence of a small string field appearing on the form with as a large string field (multi line)...  Please note, I was unable to read the PRB nor the KB, but you probably can since you're ServiceNow...

Solution Proposed:
After further research and testing, I have found you are running into PRB1239150. Unfortunately, the problem has been closed as a "won't fix". However, a solution has been given to resolve this issue.

Resolution: Open the dictionary record of the field and add the attribute "is_multi_text= false" to the record.
