Hi everyone,
I'm using <s:include> to include a page fragment in Struts 2.1.2.
(also tried with <jsp:include> and the result did not change)
Ensuring the values are passed as Strings using OGNL syntax:
<s:include value="/support/templates/header.jsp">
<s:param name="pageTitle" value="%{'Portal Administration'}" />
<s:param name="nav1" value="%{'portalAdmin'}" />
<s:param name="nav2" value="%{''}" />
</s:include>
I know nav1 makes it into header.jsp as a request parameter because this
snippet yields "nav1 = portalAdmin" (among other things)
<%
java.util.Enumeration e = request.getParameterNames();
while (e.hasMoreElements())
{
String name = (String) e.nextElement();
out.write(" " + name + " = " + request.getParameter(name) +
"<br />");
}
%>
(BTW, I tried removing %{''} from the <s:param> tag and nav1 was null)
In header.jsp I tried getting the value of nav1 using several different
OGNL mechanisms:
Nav 1a: <s:property value="#attr.nav1"/><br />
Nav 1b: <s:property value="%{#attr.nav1}"/><br />
Nav 1c: <s:property value="#attr['nav1']"/><br />
Nav 1d: <s:property value="%{#attr['nav1']}"/><br />
Nav 2a: <s:property value="#parameters.nav1"/><br />
Nav 2b: <s:property value="%{#parameters.nav1}"/><br />
Nav 2c: <s:property value="#parameters['nav1']"/><br />
Nav 2d: <s:property value="%{#parameters['nav1']}"/><br />
In theory all of the above should work because nav1 is a request parameter
and attr looks to request scope after page scope.
However, none of the above tags display the value of nav1.
Of course if I can't even get the value of that parameter my <s:if> logic
won't work.
Feels like I missed something obvious....
