Re: WO Long Response and iPhone
Hello Chuck; Assuming an instance with concurrent request processing turned on, if there are a number of sessions (or even stateless users) on the same instance with a large volume of transactions, will the streaming WORequest multiplex with the other requests? My understanding was that the WebObjects adaptor queues requests into an instance rather than multiplexes them. So if a large transaction arrives from a slow pipe, will it not block the other requests until either the adaptor times it out or a response is returned to the client? PS: The javadoc for WORequests refers to the wis request handler -- I hadn't heard of this one before! cheers. Are you using the streaming handler for uploads? If you are, there should not be any timeouts from the adaptor. I've seen uploads of large files over slow connections to GVC.SiteMaker go on for a very, very long time with no timeout. ... I wouldn't up the time on the adaptor because other clients who are using that instance will get blocked and may reach their timeouts. ...

Re: Using ERRest but with extensions for non EOF back-end
Pretty sure you can't do this ... I think the entity delegate stuff is entirely EOEntity-baed.

Re: Using ERRest but with extensions for non EOF back-end
Thank you Mike. I hadn't seen the route controller approach until you mentioned it. I think it's perfect for our needs - brilliant! We were already working on the idea that we would have two separate API apps because one part is mission critical and the other is a less important layer over the top. There are no collisions in the end points, so we hope to includes the EOEntity based one in both apps and extend on it with the non EO stuff in just one of the apps. Hopefully the two approaches will mix nicely with each other. On 15 Jan 2010, at 13:19, Mike Schrag wrote: Pretty sure you can't do this ...

I fire the fault and get back a TalentPhoto EO with PK set and nil

EODatabaseContext.objectsWithMissingGlobalIds() confirms that it's
tracking the TalentPhoto EO for me.

All is good.
I make changes to TalentPhoto:set a photo and set it's talent

Then when I try to save changes, EOF tosses a
EOObjectNotAvailableException with this explanation:
prepareForSaveWithCoordinator: Cannot save the object with globalID
_EOIntegralKeyGlobalID[TalentPhoto (java.lang.Integer)1]. The row
referenced by this globalID was missing from the database at the

That explanation seems to match what I've done and the behaviour

No DB Context delegate is my guess. :-) You may also find this code

/**
* Detecting WO 5 dummy fault EOs. The code below is a
translation of code posted here:
* From http://wodeveloper.com/omniLists/eof/2001/November/msg00023.html
*
* As of WO4.5, EOF resolves faults for objects that don't exist
in the database to a dummy object with mostly empty attributes (except
those
that are set in -init), whereas earlier versions of EOF threw a
_fireFault exception. This method detects whether the receiver is
such a dummy object.
*
* A distinguishing feature of these dummy EOs is that they
don't have a corresponding database context snapshot, so we use this
to detect its dummy-ness. This seems more robust than checking if all
or most attributes are empty, since these can be changed by client code.
*
* Dummy fault EOs should be removed from the editingContext
(using forgetObject) before it is invalidated (invalidateAllObjects or
invalidateObjectWithGlobalID), otherwise an unrecoverable
decrementSnapshotCountForGlobalID - unable to decrement snapshot
count for object with global ID exception is thrown by EOF.brbr

Hi Chuck!
From the code which I posted before, this is the method which asks the DC
associated with the given EO for all the objects which didn't exist in the
database using the missingObjectGlobalIDs() method.
private void logObjectsMissingGIDs(EOEditingContext context,
EOEnterpriseObject eo){
EOObjectStore os = context.rootObjectStore();
if(os instanceof EOObjectStoreCoordinator){
EOObjectStoreCoordinator osc =
(EOObjectStoreCoordinator)os;
EOObjectStore os2 = osc.objectStoreForObject(eo);
if(os2 instanceof EODatabaseContext){
EODatabaseContext dc = (EODatabaseContext)os2;
NSArrayEOEnterpriseObject
objectsWithMissingGlobalIds = dc.missingObjectGlobalIDs();
NSLog.err.appendln(objectsWithMissingGlobalIds
= + objectsWithMissingGlobalIds);
}
}
}

Re: WO Long Response and iPhone
Chuck, I think the streamToFilePath binding is what you need to use. What bindings are you using? I'm not using a WODynamicElement (i.e. WOFileUpload). This is a direct action for third party APIs to call so there is no UI. Or, am I misunderstanding your question?
