Dear all,
I have a problem when I click a submit button of a page, it doesn't go
straight to the next desired page.
Here is my little project:
Firstly, I want to show you how it supposed to flow:
Input page -> Help page
But the problem is it does go to the Help page when I click the submit
button on the Input page.
Here are the source files:
--- input.jsp:
============================================
# cat input.jsp
<%@ include file="/html/portlet/struts_redirect_portlet/init.jsp" %>
<p align=centre>
Hello the INPUT page.....
</p>
<bean:define id="comment" name="RedirectForm" property="comment"
type="java.lang.String" />
<logic:messagesPresent>
<span class="es-error">
<bean:message key="error.comment.invalid"/>
</span>
</logic:messagesPresent>
<p align=centre>
<html:form action="/struts_redirect_portlet/input" method="post"
focus="comment">
<table class="stats">
<tr>
<th><bean:message key="form.title.comment"/></th>
<th><html:text name="RedirectForm" property="comment" size="50" /></th>
</tr>
</table>
</p>
<p align=left>
<html:submit><bean:message key="button.submit"/></html:submit>
</html:form>
</p>
--- help.jsp:
=============================================
# cat help.jsp
<%@ include file="/html/portlet/struts_redirect_portlet/init.jsp" %>
<p align=centre>
Hello the HelP FORM ??.....
</p>
<bean:define id="name" name="RedirectHelpForm" property="name"
type="java.lang.String" />
<logic:messagesPresent>
<span class="es-error">
<bean:message key="error.name.invalid"/>
</span>
</logic:messagesPresent>
<p align=centre>
<html:form action="/struts_redirect_portlet/help" method="post" focus="name">
<table class="stats">
<tr>
<th><bean:message key="form.title.name"/></th>
<th><html:text name="RedirectHelpForm" property="name" size="50" /></th>
</tr>
</table>
</p>
<p align=left>
<html:submit><bean:message key="button.submit"/></html:submit>
</html:form>
</p>
