S2: how to deal with NULL value with s:text tag?

[Burton Rhodes]

The following entry works fine, but when "xaction.contractPrice" is
NULL it prints out "null" on my web page.
<s:text name="format.money"><s:param value="#xaction.contractPrice"/></s:text>

This sort of fixes the issue, but I would prefer to not display a "$0".
<s:text name="format.money"><s:param
value="%{#xaction.contractPrice==null ? 0 :
#xaction.contractPrice}"/></s:text>
This does not work as I get an error: "cannot forward object as a number"
<s:text name="format.money"><s:param
value="%{#xaction.contractPrice==null ? ' ' :
#xaction.contractPrice}"/></s:text>

Properties file entry:
format.money = {0,number,\u00A4###,##0}
               
Is there something simple I am missing or a better way to do this? Is
there a "$!" like freemarker or a "default value" parameter?

Hi,

I have had same problems when displaying dates.
The only solution I found was quite similar but maybe a little more flexible
since you can choose to display nothing:
<s:property value="#item.referenceDate != null ?
getText('format.date',{#item.referenceDate}) : ' '" escape="false"/>

Thanks for the reply.  There should definately be some sort of
enhancment to the <s:text> tag.  I found a more susinct solution with
the <fmt:formatNumber> tag - it doesn't display the "null" text if the
value is null.  Anyone know if there is a request to add a "null"
feature to <s:text>?  The <s:date> tag handles "null" without
displaying "null" text.  Wonder why <s:text> is different?  I can't
think of many situations where the UI calls for displaying "null" when
a value being displayed is in fact null.

<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %>
<fmt:formatNumber value="${xaction.listPrice}" type="currency"
maxFractionDigits="0"/>

<s:date name="#xaction.closingDate" format="MMM dd, yyyy" />

If JSTL functionality is the same as the S2 tag then the JSTL tag should
be preferred anyway.
