I'm new to Struts, but old at JSP / Java / Servlets. I cannot figure
out why this is happening.
When I run the page below, the struts tag does not output the value in
my bean. I added the standard JSP tags later to be sure the values are
being set, and the output there is fine.
-----------------------CounterpartyForm.jsp---------------------------
<[EMAIL PROTECTED] uri="/struts-logic" prefix="logic"%>
<[EMAIL PROTECTED] uri="/struts-bean" prefix="bean"%>
<[EMAIL PROTECTED] uri="/struts-html" prefix="html"%>
<jsp:include page="/struts-views/Heading.jsp">
<jsp:param name="heading" value="Counterparty Form"/>
</jsp:include>
<jsp:useBean id="counterpartyForm"
class="com.sam.trading.web.struts.forms.CounterpartyForm"
scope="request"/>
<html:form action="/viewCounterparty.do" name="counterpartyForm"
type="com.sam.trading.web.struts.forms.CounterpartyForm">
Name: <html:text property="counterparty.name"/><%=
counterpartyForm.getCounterparty().getName() %><br/>
Parent: <input type="text"><br/>
Fee Type: <input type="text"><br/>
Fee Amount: <input type="text"><br/>
Credit: <input type="text"><br/>
Credit Zero: <input type="text"><br/>
</html:form>
<[EMAIL PROTECTED] file="/struts-views/Footer.jsp"%>
-----------------------Page done----------------------------
In this line:
----
Name: <html:text property="counterparty.name"/><%=
counterpartyForm.getCounterparty().getName() %><br/>
----
The <html:text property="counterparty.name"/> tag outputs <input
type="text" name="counterparty.name" value="">
while the <%= counterpartyForm.getCounterparty().getName() %> outputs
"ABPN" (which is correct for this run of the page)
Any ideas?
For grins, here are my struts-config.xml, and all the supporting Java
code:
