The test passes with that change in > place. The GC + child editing context thing sounds like a problem we ran into a couple years ago ... From my notes: "The essence of the problem is that EO's track retain count as an ivar. This retain count records how many nested ec's contain that EO as well, because they share a snapshot (with refcount = 1). If, however, the parent EO gets garbage collected while the nested EC version of it is still alive, the parent EO's retain count disappears and it throws off the snapshot ref counting. We talked about this and bounced around a couple ideas, but ultimately the one that seemed to have the least side-effects was to track the retain count in the EC rather than the EO. This patch provides an impl of that concept -- retain count is now removed from EO and pushed up into a dictionary in the EC. Now even if the underlying EO gets GC'd, the retain counts won't be lost." ms ___ Do not post admin requests to the list. They will be ignored.

Late WOWODC purchases
Hi guys, If one of you is coming to WOWODC but still didn't get their ticket, remember that you have up to June 21 to buy your ticket. But more important, I need to give the final headcount to the hotel next week, so if you are planning to come and I don't have your name on my list, please email me.

Is this the joda thing that is being discussed earlier this week?
I have a classic Wonder App that is working just fine. However, I want to add some login capability and auditing and attachments. I have a framework for the model so I decided to use D2W for the interface as I have been playing with D2W and I am starting to feel Ok with it. My problem is that the model has some Entities that contain attributes of type jodaLocalDate. as soon as I try to list the Entity my app explodes with: Application: POGridD2W Error: java.lang.NoSuchMethodException: Class org.joda.time.LocalDate does not implement method jodaLocalDate Reason: Class org.joda.time.LocalDate does not implement method jodaLocalDate Or am I doing something like not adding a needed framework?

Re: 5.4 uploading large files
Downloading large files works fine, for uploads there are several bugs in the WO code. I reported it via the Apple bug reporter some time ago. Problem ID: 10765546 There is no workaround, here is some input in case somebody from Apple is looking into it: The class com.webobjects.appserver._private.WOHttpIO tries to parse the content-length header with the method parseInt of the Integer class. This will fail for all files larger than 2.1GB. Further there are many instances in the code that make use of an integer for the content length of a request: WOInputStreamData: public WOInputStreamData(InputStream, int) WORequest: public int _contentLengthHeader() Also classes not directly involved in the request handling do show such a limitation (e.g. public NSRange(int, int)).

Did you have a contract that obligated Apple to continue to support you? What grounds to you believe you have for a law suit? I'm just curious. Yes it's a somewhat comical notion :-) Just to make your point/question clearer for people: the said product was supplied for free for the last few releases. So if people were to sue for damages, it would need to be a very strong case indeed! I'm sure Apple would be happy to supply a full refund ;-) More seriously, I think the sentiment is coming from promises (or assumed promises) that were made when, for example, the Xcode tools were dropped. The reasoning given was to concentrate on enhancing the frameworks. Thus the initial impression given to the community by Apple (bolstered by its funding of tools like WOLips) was that a renewed energy was being put into WO by Apple that people could continue to build their business apps with. And, there was some initial promise of better community involvement in the evolution of WO when the Apple maven repo was made available (which showed some future versions in the works). It didn't last long though which was a shame at the time, especially for us maven users. Hmm so, perhaps it was the community's unwillingness to embrace maven that canned it moving forward :-) What are you trying to say? Maven killed WebObjects? Why am I not surprised. :) cheers, Lachlan Deck ___ Do not post admin requests to the list. They will be ignored.

You can just roll your own tracker and track any string you like (build a
