Hi,
I'm wondering if I can use custom <binder> when I'm binding a collection.
The code below is illustrating what mean:

Code:
    <view-state id="addMessages" model="messagesBean">
        <binder>
            <binding property="messages"/>???
            <binding property="someDate" converter="shortDate" required="true"/>
            <binding property="file"/>
        </binder>
        <transition on="proceed" to="reviewMessages">
            <evaluate expression="messagesBean.proceedMessages()"/>
        </transition>

        <transition on="cancel" to="cancel" bind="false"/>
    </view-state>
Code:
public class SomeObject implements Serializable {

    private transient MultipartFile file;
    private Date someDate;
    private List<String> messages =
            LazyList.decorate(new ArrayList<String>(),
                    new InstantiateFactory(String.class));

    public Date getSomeDate() {
        return someDate;
    }

    public void setSomeDate(Date someDate) {
        this.someDate = someDate;
    }


    public void setFile(MultipartFile file) {
        this.file = file;
    }

    public MultipartFile getFile() {
        return file;
    }

    public List<String> getMessages() {
        return messages;
    }

    public void setMessages(List<String> messages) {
        this.messages = messages;
    }

}
The thing is when I want to have a converter for some property (someDate property in my code) and bind some objects collection at the same time (messages property in my code), binder for the ArrayList<String> is not working. So, what I would like to learn is how can I assign a converter for the date field when my form contains a collection of objects. Unfortunately, I was faild to find an answer in the documentation and at the forum. Please, point me to a code sample or instruction in the documentation or even make me known if it is possible to do and if it is possible what I have to change in my code.

I wanted to note that if I remove <binder> section from the flow configuration file and use String instead of Date type for someDate property in my SomeObject class everything is working fine.

Thanks,
Pavel
