Messages from messages.properties ignore line breaks in notifications and prompts

Support
#1

Hello!

I’m facing an issue with line breaks in io.jmix.flowui.Notifications and tooltips when using text from message bundles.

Configuration:

  • Jmix version 2.4.5
  • File messages_ru.properties contains:

properties

Copy

Download

passwordValidator.invalid=Password doesn't meet requirements: \n Test1 \n Test2 \u000A Test3

Problem:
The system loads the text correctly (as shown in the screenshot), but ignores line breaks when displaying via Notifications and tooltip. All special characters (\n, \u000A) are rendered as regular spaces.

Question:
What is the correct way to implement multi-line messages in notifications and tooltips when using messages.properties?

Hi!

Have you tried using a special LumoUtilityClass LumoUtility.Whitespace.PRE_LINE?
