Problem with sending to server ValueProxy which contains List of EntityProxy after has been decode by AutoBeanCodex

Hi

Assume I have following ValueProxy

@ProxyFor(value = MailFilter.class)

public interface MailFilterProxy extends ValueProxy

{

    String getQuery();

    

    void setQuery(String query);

    

    List<ContactProxy> getFrom();

    

    void setFrom(List<ContactProxy> from);

}

User edits this proxy in some Editor<MailFilterProxy>. After this this proxy encoded to payload by AutoBeanCodex:

AutoBean<MailFilterProxy> bean = AutoBeanUtils.getAutoBean(mailFilter);

String payload = AutoBeanCodex.encode(bean).getPayload();

encoding FilterProxy to string is needs to get right URL for list of MailProxy, somthing like #ml:f={encoded filter payload}

and representation filter for list as ValueProxy to be able to use GWT Editor & Driver framework (don't know right name of this functionality)

Next, users goes to list place with new filter payload:

getPlaceController().goTo(new ListPlace(MailProxy.class, payload)

in list Activity I trying to decode this payload into MailFilterProxy:

MailRequest request = getRequestFactory(); // some request for mails

MailFilterProxy filter = request.create(MailFilterProxy.class);

AutoBean<MailFilterProxy> bean = AutoBeanUtils.getAutoBean(filter);

AutoBeanCodex.decodeInto(StringQuoter.split(getPlace().getFilterPayload()), bean);

filter = bean.as();

next I trying to fire list request with new MailFilterProxy

request.getList(filter).with(getWith()).fire(new Receiver<List<MailProxy>>(...));

And I catch an exception:

Unfrozen bean with null RequestContext

This occurs because AutoBeanCodex uses MailRequestImpl_FactoryImpl for creation of ContactProxy - list items, but not MailRequest 

and it was not set any tags (REQUEST_CONTEXT_STATE, STABLE_ID)

What I'm doing wrong? How to do it right or some workaround?
