line breaks disappearing in a inputTextArea ajax submit

[ljcollazos]

I have a form and one of the fields is a inputTextArea.
Clicking on a a4j: commandButton form fields to pass some hidden fields for later use.
If textArea contains line breaks to pass the value to the hidden field you do not appear, and I need to display a PDF document.

I have seen with firebug in the ajax response not appear:

Post:

formCiudadano:expone  one line

                                   two line

Response:

<input id="expone" type="hidden" name="expone" value="one line two line"/>

I use RichFaces 3.3.4 on JBoss EAP 5.2
Is it a configuration problem?
Do I have to replace the '\ n' by other characters?

Regards

I found a solution but not if it will be the best way to do it.

Instead of using hidden input I use a "hidden" textarea for fields that can have line breaks:

<textarea name="expone" id="expone" style="display:none;"> <h:outputText value="#{solicitudCiudadanoQYSBean.expone}"/> </ textarea>

So the format is maintained and these fields display correctly in my PDF document.
