Accesing actionForm in TILES
----------------------------
Key: BEEHIVE-568
URL: http://issues.apache.org/jira/browse/BEEHIVE-568
Project: Beehive
Type: Test
Components: NetUI
Versions: V1Beta
Environment: Windows XP, Tomcat 5.0.28, JDK 1.5
Reporter: V.Gnanasegaran
Pleace look into the sample code.
Page A (some.jsp)
<tiles:insert flush="true" page="/resources/jsp/mal/layout.jsp">
<tiles:put name="sometips" value="/nae/nae011/tips.jsp"/>
</tiles:insert>
Layout page B (layout.jsp)
<%@ page language="java" contentType="text/html;charset=UTF-8"%>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-tiles"; prefix="tiles"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core"%>
<%@ taglib uri="bjeff.tld" prefix="bjeff"%>
<html>
<body>
<netui:form action="goForward" tagId="htmlForm">
<table cellspacing = "0" cellpadding = "0" border = "0">
<tr>
<td class = "layoutLeft" rowspan = "1">
<jsp:include page="navigator.jsp" />
</td>
<td class="layoutContent content">
<tiles:insert attribute="sometips" />
</td>
<td class = "layoutRight" rowspan = "2">
<netui:content value = "${actionForm.something1}"/>
</td>
</netui:form>
</body>
</html>
Inserted page C (tips.jsp)
<%-- netui:form action is NOT defined here --%>
<netui:textbox dataSource="actionForm.something2"/>
As you see in the code sample when I run the code I have got two problems.
1) Occures an exception "Caught exception when evaluating expression
"{actionForm.something2}" .Can not evaluate
the identifier "something2" on a null value object". This means when
the page C is executed the actionForm
is null. If I define a netui:form then it desplays. As this page is
inserted in the layout page actionForm
must be available to page C.
2) When the form is submitted to the Controller, the controller does not get
the updated form attribute values.
I would like to know why actionForm is null when executing tips.jsp. But
pageFlow is a valid instanse when
executing tips.jsp. The second question is depend on the answer of the
first one.
