How to get the value (with line breaks) of a multiline text field?

[Sascha Ziemann]

I use the function getCustomFieldValue to read the value of a multi-line custom field. But when I use toString() on the return value, the line breaks disapear. The string contains just spaces.

How can I preserve the line breaks?

Line breaks are there. It was just a display error.
