Hi Edward, See if this posting might help:
http://www.objectstyle.org/cayenne/lists/cayenne-user/2006/04/0073.html In a nutshell, when using Tapestry 4 + Cayenne, I don't serialize any Cayenne objects through Tapestry. The posting has more details. /dev/mrg PS. I used to pass my objects around with an ActionLink (now deprecated) in Tapestry 3, but changed my techniques when I moved to Tapestry 4. Also, I only use DirectLink now -- PageLink has some session quirks. On 10/23/06, edward pedersson <[EMAIL PROTECTED]> wrote:
Hi I noticed you post in the archives [RE: "Can't build a query for temporary id" after upgrade from 1.2B2 to 1.2RC2] here http://mail-archives.apache.org/mod_mbox/incubator-cayenne-dev/200607.mbox/[EMAIL PROTECTED] I seem to be having problems which might be similar to yours. I could not see how you resolved your problems but maybe if you tell me how you were doing a few things I may be able to solve my own problems. I am using Tapestry 4 and Cayenne 1.2 When you said "...hen my objects are unserialized and reattached to their datacontexts on the following request.." were you just doing anObject.setDataContext(this.getDataContext()); anObject.getDataContext ().getObjectStore().resolveHollow(anObject); where anObject is an object that is a listener parameter to the method so I am assuming it has been serialised and is unserialised when I get it at this point. The object is hollow as well. Is this the best way to reattach the object back to the dataContext? My problems don't stop there as the code itself runs ok but not correctly. The object remains hollow and looking into the ObjectStore's public void resolveHollow(DataObject object) method I noticed there is this call List results = context.getChannel().onQuery(context, query).firstList(); but nothing is done with that results List. I have inspected the results List and it is in fact the object I need but the method does not return the list or the object. Is there something I am missing here i.e. the object passed in is updated elsewhere? I have followed the object graph and could not find it. Any help would be much appreciated. Regards -- -- e
