manually defined multiline fields in entry editor do not work

[ilippert]

This is
JabRef 5.0-dev--snapshot--2018-10-14--master--73ec32189
Linux 4.18.12-200.fc28.x86_64 amd64
Java 1.8.0_172

In this and prior dev versions, I seem not be able (anymore) to define multiline fields in the entry editor. I used to have defined an own general field with multiline content; but now this is not shown as such any more. Only, I guess pre-defined, fields like "Abstract" are shown as multiline fields.

just for reference - I am referring to those fields I defined in
JabRef 4.3
Linux 4.18.12-200.fc28.x86_64 amd64
Java 1.8.0_172

at JabRef preferences | File "Do not wrap the following fields when saving"

Hi everyone! Has this been resolved for the now released version 5.0? I just installed it and all the manual linebreaks are gone despite the respective list. What seems odd: They are only missing in the "annote"-field, while everything is fine in "abstract" or "comment". Does anyone have an idea? Thank you!

I confirm:
JabRef 5.0--2020-03-08--93de138
Linux 5.5.7-200.fc31.x86_64 amd64
Java 13.0.2
the issue is not solved.

I looked into the code and it's hardcoded for abstract and comment:

jabref/src/main/java/org/jabref/model/entry/field/FieldFactory.java

Lines 142 to 149 in b5002e0

	// TODO: Move somewhere more appropriate and make user-configurable
	public static boolean isSingleLineField(final Field field) {
	if (field.equals(StandardField.ABSTRACT) || field.equals(StandardField.COMMENT)) {
	return false;
	}
	// Treat unknown fields as multi-line fields
	return !(field instanceof UnknownField);

As the "Do not wrap fields" aka multine are already stored in the preferences as part of the FieldContentFormatterPreferences it can be used.

1. Pass the preferences down to the above method and check the list
2. If it's in the list => multiline
3. Otherwise single line

I am terribly sorry, but I would love to insist that this is an issue that is really preventing me from using jabref well. This bug prevents me from using all my manually defined multiline fields. Please, please add it to the agenda for v5.1 again ;) - and lots of health and good spirit in the hard covid19 times!
