problem with tiles in html:form

[S Bhanu]

I am using multiple struts tiles in html:form and the form is getting submitted more than once. See this:

javax.servlet.jsp.JspException: Exception forwarding for name error: javax.servlet.ServletException: Exception forwarding f
t.ServletException: Exception forwarding for name error: javax.servlet.ServletException: Exception forwarding for name erro
eption: Exception forwarding for name error: javax.servlet.ServletException: Exception forwarding for name error: javax.ser
ption forwarding for name error: javax.servlet.ServletException: Exception forwarding for name error: javax.servlet.Servlet
ding for name error: javax.servlet.ServletException: Exception forwarding for name error: javax.servlet.ServletException: E
e error: javax.servlet.ServletException: Exception forwarding for name error: javax.servlet.ServletException: Exception for

at jsp_servlet._layout._jsp.__errors._jspService(__errors.java:166)
at weblogic.servlet.jsp.JspBase.service(JspBase.java:33)


the code looks like this:
Layout.jsp
<html:form action="<%=request.getAttribute("fwdTo").toString() %>">
<tiles:insert name="header"/>
<tiles:insert name="navig"/>
<tiles:insert name="body"/>
<tiles:insert name="footer"/>
</html:html>

I need to mandatorily put all the elements in HTML in the form to submit. Is there any restriction in putting multiple tiles in html:form ?
Please note that I am using filer in the web.xml

Can somebody explain what is worng with putting tiles inside html:form tag?

Using tiles:insert insert within a html:form tag works, as I have done this in a number of instances. I noticed looking at my code that I have used the format <tiles:insert component="XXX" /> but looking at the documentation it says that page, component and template are all equivalent.

Does one of your tiles have a logic:forward tag? That looks like the problem based on your stack trace.
