Adding empty line to modelattribute

**ufotje** · January 14th, 2019, 09:14 PM

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.

Good question! I checked and it is...
this is on the console:
Username already chosen!

This e-mail is already registered.
Did you forget your password?

This is on the actual page:
Username already chosen! This e-mail is already registered. 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?

I did try <br> but it's not html text it's a StringAttribute in the model

displayed in firefox

I guess that was confusing.

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