Adding the character limit to the specified fields

[Params]

Hi

I like to Implement a character limitation for my multitext custom field, which will restrict 600 characters during create / Edit  of the any issue type. 

I can perform using the Workflow validator, but it restrict only when the issue is created. 

I like to know is there any way i can restrict characters in custom field.

Hi, I did solve this issue using Forms. Here you got to the validation menu & set a limit.

You can check regular expressions against field values using Behaviors:

You can use this technique with a regular expression that counts the number of characters in the string.

I tried regular expression in Workflow Validator when the issue is getting created, but the validation applied to all the issue type. This worked as expected for that custom field with default error message. But issue was when the user select another issue type where this field is not mapped, it restricts the user to create the issue. 

Is there any other option to restrict the character for a custom field in either case Create and Edit. But i have a limitation to download any new licensed plugins (third party app). 

I appreciate your help to overcome this issue.
