Hi,
What is the best way of setting a Java Collection which holds Java
Objects
as a property of the form, and retrieving the Object and it's properties
on a JSP?
I've tried it as such but have not been successful:
In my action, I have created a list called "myList" which holds objects
of type "myClass".
"myClass" has an attribute "name" and a getter method "getName". In the
action I set the list
as a property of a DynaValidatorForm:
form.set("availableNamesList", myList );
In struts-config:
<form-bean name="newNameForm"
type="org.apache.struts.validator.DynaValidatorForm">
<form-property name="selectedName" type="java.lang.String"/>
<form-property name="availableNamesList" type="java.util.List"/>
</form-bean>
In the JSP:
<html:form action="/addNewName" >
<html:select property="selectedName" size="5" multiple="false">
<html:options collection="availableNamesList"
property="name" />
</html:select>
</html:form>
This results in the error: [ServletException in:/jsp/newName.jsp] Cannot
find bean under name availableNamesList'
If I put the list in session scope in my action with:
request_.getSession().setAttribute("availableNamesList", myList);
this works fine.
I'd like to avoid having to put the list in session scope and I don't
understand why just setting the list
as a property of the form doesn't work.
Any help/guidance would be appreciated.
Thanks,
SB
