Textfield (single line) using the Default Text Renderer shows the null string

Ji-Sung Kim

I added custom text filed (single line) with the default text renderer in my JIRA about two years ago, and we had used well without any problems.

But suddenly, the problem arose last month. It has begun to show null string when the value was rendered like below.

When i click the value to edit, the null string disappear. 

Rendered view: US16-E-EPnull-002

Edit view: US16-E-EP-002

 

How can i fix this problem?

What JIRA version do you have? This might be because JIRA is interpreting that lin "EP-002" as a JIRA issue # (an issue pattern in the Advance Setting) and it's not finding anything. That's my best guess.
