Here is an overview of the issue:

Key: XDT-1367
Summary: Uninitialized "subform" objects from @struts.form
Type: Bug
Status: Open
Priority: Major
Original Estimate: Unknown
Time Spent: Unknown
Remaining: Unknown
Project: XDoclet
Components:
Apache Module
Versions:
1.2.3
Assignee: xdoclet-devel (Use for new issues)
Reporter: Nathan Egge
Created: Wed, 27 Apr 2005 3:33 PM
Updated: Wed, 27 Apr 2005 11:47 PM
Environment: Gentoo Linux x86/2005.0/2.4
[blackdown-jdk-1.4.2] "Blackdown JDK 1.4.2"
Description:
When generating Form objects from POJOs with the @struts.form
include-all="true", the Form object it creates leaves all the attributes
uninitialized. If my POJO contains another POJO, the resulting generated form
has a "subform" that is not initalized in the form.
If I have the following jsp code that renders a select based on the id of a
"subform" called type,
<html:select property="type.id">
<html:options collection="types" property="id" labelProperty="name"/>
</html:select>
when I submit this form I get the following exception:
java.lang.IllegalArgumentException: No bean specified
at
org.apache.commons.beanutils.PropertyUtils.getPropertyDescriptor(PropertyUtils.java:837)
at org.apache.commons.beanutils.BeanUtils.setProperty(BeanUtils.java:934)
at org.apache.commons.beanutils.BeanUtils.populate(BeanUtils.java:808)
at org.apache.struts.util.RequestUtils.populate(RequestUtils.java:495)
at
org.apache.struts.action.RequestProcessor.processPopulate(RequestProcessor.java:798)
at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:205)
at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1164)

at javax.servlet.http.HttpServlet.service(HttpServlet.java:709)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
...
This is because the all of the non-primative types in the Form are left
uninitialized. The correct behaviour would be to create a new object for each
member variable.
