Do not collapse whitespace when displaying the value of the backing bean in the JSF

I found that the backing bean value displayed on the JSF page will collapse the white-space automatically .How can I make the value displayed do not collapse the white-space??

For example , I have a MBean which has a String variable test and assign the value

"test                  test"

, when I render it using <h1>${MBean.test}</h1> , it just give out test test which all the white-spaces in the middle collapse to a white-space only.

This behavior also happens if I display the ArrayList from the MBean in the table format using the <rich:dataTable> , all the white-spaces will be collapsed too.

Updated: I still think that it is specific to the JSF , because when I use <h:inputText value="#{MBean.test}"/> , the rendered input text box will collapse all the white-spaces.How can I preserve开发者_C百科 all the white-spaces in this case??

This is not specific to JSF. This is specific to HTML

You can fix it by either putting it in a HTML <pre> element:

<h1><pre>#{bean.text}</pre></h1>

Or by applying CSS white-space: pre on the HTML element:

h1 { 
    white-space: pre;
}

(as you see, it also occurs on your question here on Stackoverflow as well, since it also doesn't preserve whitespace by white-space: pre)

Sun's JavaServer Faces implementation (1.2_07-b03-FCS) has the same issue on Webshpere Application Server 7.0.0.21 for the CSS white-space: pre
