Question

I have some text which I want to have on separate lines.

I try to println this with label:

add(new Label("output",output));

<span wicket:id="output">Will be replaced</span>

Problem with this code it that it is ignoring formatting new line. Is there better way how to println some text?

Answer 1

There are two options:

1. Use a <pre /> (as in: preformatted) tag instead of <span />. If you have new line markers in your text, it will work, because browsers do not format text that is placed inside the <pre /> tag.

2. Use Wicket’s MultiLineLabel class. After the Javadoc:

   Unlike Label, MultiLineLabel shows text that spans multiple lines by inserting line breaks (BR tags) for newlines and paragraph markers (P tags) for sequences of more than one newline.

Note, that if using the MultiLineLabel class, you should not use a <span /> tag in your HTML, as placing paragraphs (<p />) inside <span /> is considered bad practice.
