    Question Adding empty line to modelattribute

    Hi Guys

    I'm new to this forum, so don't shoot me if i posted in the wrong place.
    I have a springBoot app that uses a modelAttribute to return a message when an error occurs while login in.
    Everything is working fine, but something bugs me. The error message is concatenated together.
    I wan't to add some line separators to the errormessage.
    I've tried System.lineSeparator(), \n an <break> but nothing seems to work.
    I use a stringBuilder to build the message and then call the to string message when adding the attribute to the model.
    Any tips?

    Is this a standard java question or is the problem caused by the framework?
    Can you print the String that is being created to see if the new-line character is honored on the console.

    Did you forget your password?

    So is there any documentation that says that new-line characters will be removed?

    Does the software that displays the message support the new-line character you are using.
    For example on Windows, Notepad needs \r\n for a new-line.

    I use intelij as idea, so it supports new-line and it's actually being displayed in firefox, since it's a webpage and they shouldn't have any issues with it...
    Just to be shure I tried "\r" and "\r\n" didn't work eather

    If it is html text, did you try the <br> tag?

    displayed in firefox
    I guess that was confusing.

    I don't know the framework and can't suggest anything else.
