multiple instances of domain object?

[anicad]

Hi,

Is it possible to have multiple instances of a domain object on one form? If so, when an error occurs in one field, how does the BindException object know which instance the error occured in?

Thanks.

public class MyCommand {

public MyDomainObject getDomain1() {
...
}

public MyDomainObject getDomain2() {
...
}
}



<spring:bind path="command.domain1.someField">
...
<spring:bind path="command.domain2.someField">

Is this what you mean?

Or you could use a collection

public class MyCommand {
public Collection getDomainObjects() {
...
}
}

and at jsp page you could write something like this

<c:forEach items="command.domainObjects" var="domainObject" varStatus="status">
<spring:bind path="command.domainObjects[${status.index}].someField">
...
</spring:bind>
</c:forEach>

I'm trying to create multiple instances of my domain object when the flow starts.
For example, below is my FlowAction class definition
<bean id="formAction" class="org.springframework.webflow.action.FormAction">
<property name="formObjectName" value="searchCriteria"/>
<property name="formObjectClass" value="org.springframework.webflow.samples.phonebook.doma in.SearchCriteria"/>
<property name="formObjectScope" value="FLOW"/> </bean>
How do I set up the properties, so that I have another SearchCriteria Object with the object name "secondSearch"?

why do i need the command class?

It's your form object that wraps multiple instances of your search criteria. You could of course put it in a scope and then access them from your page but using a form object feel a lot nicer to use
