Andrea Ligios created WW-4228:
---------------------------------
Summary: OGNL Basic: if AllowStaticMethodAccess is set to true,
JSP fragments included with <jsp:include/> can access Action members, otherwise
they can't.
Key: WW-4228
URL: https://issues.apache.org/jira/browse/WW-4228
Project: Struts 2
Issue Type: Improvement
Components: Documentation
Environment: JBOSS EAP 6.01, Struts 2.3.15.2
Reporter: Andrea Ligios
Priority: Trivial
Trying to call an Action's getter from an included JSP, I get null:
{code:title=MyAction.java|borderStyle=solid}
private String message = "The message I want to read...";
public String getMessage() {
return message;
}
{code}
{code:title=main.jsp|borderStyle=solid}
<%@taglib prefix="s" uri="/struts-tags" %>
<html>
<head></head>
<body>
<div> I'm a DIV in main.jsp </div>
<jsp:include page="fragment.jsp" />
<body>
</html>
{code}
{code:title=fragment.jsp|borderStyle=solid}
<%@taglib prefix="s" uri="/struts-tags" %>
<div>
I'm a DIV from fragment.jsp
<br/>
Message from Action: <s:property value="message" />
</div>
{code}
If I set:
{code:title=struts.xml|borderStyle=solid}
<constant name="struts.ognl.allowStaticMethodAccess" value="true"/>
{code}
the getter is now reachable.
This applies only to <jsp:include> ; with <s:include>, the getter is ALWAYS
reachable.
Seems to be some kind of side effect, maybe it should be verified and added to
the documentation. [Originally posted
