How to store a String[] in a hidden field?

[Christian Bouessay]

Hi,
I have a form with a multiple select box.

class myForm1 extends ActionForm {
     String[] getFields() { ...}
     void setFields(String[] fields )
     ...
}
<html:select property="fields" multiple="1" size="3">
     <html:options collection="list" property="value"
                                     labelProperty="label"/>
</html:select>

When I submit the form and validate() return null, it forwards to an 
other view of the same form where I would like to store this property in 
a hidden field.

And HTML output is:

<input type="hidden" name="fields" value="[Ljava.lang.String;@1765ae">

How can I tell struts to store it in a "String" format?


Thanks for help.
