You know, you could at least *pretend* to be surprised.

My imagination is only so good.
Are you manually disposing editing contexts?
No. However, I am calling revert() on the nested ones if they have errors()
but I leave them for GC to get rid of them...

Hey all,

I can see that the _dbSnapshot is completely empty and I know that that is
what it’s complaining about. The object exists in the DB with a PK
matching the id value, which matches up with the _object and the
_globalID. How could the _dbSnapshot end up empty? What
horribly-inappropriate thing have done?
I have gone over everyplace I instantiate “MYEntity” and I’m never using
the EO’s constructor, it’s always being done by
ERXEOControlUtilities.createAndInsertObject(editingContext, “MYEntity”).
As far as I can tell I’m never crossing EC boundaries without
localInstancing it.
Is there anything else that can cause the _dbSnapshot to be empty?
I’m making use of multiple EOObjectStoreCoordinators, 1 each for two
different EOModelGroups, but this code should only ever be using the
defaultModelGroup in the defaultObjectStoreCoordinator. So I don’t *think*
it has anything to do with that, but, well, I’m me and I do stuff all the
time that future me is shocked at.

Re: Problem with pages saved in a variable
Andri,
I don't what exactly you want do, but have a look on API Session :
restorePageForConextID, savePage, savePageInPermanentCache.
You can start to override this API and just log, to understand how
WebObjects works with pages and contextIDs.
HTH,
Stephane
Le 13 oct. 09 à 10:29, Andri vonAllmen a écrit :
Dear List,
in an Applications Session, a NSMutableDictionary object is used for
caching pages. Everytime the pageWithName method is called, the
dictionary is queried in order to determine if the requested page does
already exist, if true the existing page is returned, else a new
one is
generated and stored in the dictionary. This is made in
Application.java
by overriding the pageWithName method:
public WOComponent pageWithName(String aName, WOContext aContext) {
Object result = null;
if ( aContext.hasSession() ) result =
((NSMutableDictionary)((Session)aContext.session()).cachedPages
()).objectForKey(aName);
if ( result == null ) {
result = super.pageWithName(aName, aContext);
if ( aContext.hasSession() ) if ( aName != null )
((NSMutableDictionary)((Session)aContext.session()).cachedPages
()).setObjectForKey(result,
aName);
}
return (WOComponent)result;
}
This works with one exception. Making changes on Enterprise Objects is
not possible in every case. Saving changes works, if always the same
object is changed but not if two different objects are changed
(changing
the first, saving the changes, then changing the second and saving the
changes). But if making changes on a object, saving it, and then
revert
the changes (to the same state as before changing it the first time),
making changes on other objects is possible.
As mentioned in the WO API Reference, for pages being stored in a
variable the ensureAwakeInContext method has to be called, but this
has no effect. Same if refreshing the objects in the default editing
context (refreshAllObjects, refaultAllObjects) which is used on
all
pages.
Any suggestions or other hints would be appreciated.
Regards
Andri

What could we do to convince Apple to opensource WebObjects ?
Hi, my primary goal was not to discuss about patents. I just think that WebObjects is a WOnderfull technology, very well integrated solution ( EOF+WO ) I've spent 10 years developping with WO, but for 3 years now I'm working with Flex. Nice technology, server side agnostic, you can use whatever you wants on the server side, and to be honest less I work on the server better am I, J2ee is simply a nigthmare, non-ecolgic technology, you needs so much time and energy for simple things with WO. EOF is much more simplier than Hibernate WebObjects is much more simpler than JSF, WebFlow and all Spring technologies and concepts ( Inversion of Control ) you don't needs 100 jars to do web application. Apple may benefits from WebObjects Halo effect, if they decide to opensource the technology. Patents, is just money, and it seems that Apple has some cash in Bank ( 30 B$, today Apple is bigger than IBM, and SUN is in my point of view the Lehman Brother of IT ). I know that the community, Mike, Chuck, Pascal, Anjo and ... , are doing great work to promote WO, but I not totally agree the way they do it. I give enough money to Apple, buying Macs, iPhone, iPods and iTunes Music ( I'm very happy client, http://itunes.apple.com/WebObjects/ MZStore.woa/wa/viewAlbum?i=191345352id=191345213s=143442 ), I don't wants spent time to do the marketing of a non opensourced product (WebObjects), marketing they have never done. The question I'm asking to myself and you , what could we do to convince Apple to opensource WebObjects ? Why Apple is doing opensource for some technologies , WebKit, Grand Central Dispatch ... but not for WO ? Perhaps someone inside Apple may publicly give us some good reasons ...

I have no idea about Pharma, but I presume that once a drug is released, it's probably pretty easy for generics to replicate it. It does seem there should be some consideration for that, and the patent system is the current answer to that. Why should software be in some other category? Also, re: MP3/JPEG (and things like RSA fall into this category too) -- It's grunt work to do it once someone already has defined a spec, or figured it out and you cheat off their paper, but it's no small feat to come up with it in the first place. This is sort of the point, it seems to me. Stealing the idea is always easier than making it first, so we have patents to give incentive to people to bother coming up with it first. There's obviously a failure window in the patent system for the guy who truly independently develops it, but I don't really see a way to close that gap -- i think it's a weakness you have accept for the greater good of the imperfect system. Personally I have no issue with the concept of software patents in general, it's how they are often used I object to. Patents should be a way to protect yourself from having to compete against your own invention in a commercial market. Ie. Patents should exist for the purpose of protection from direct competition and utilising an idea or invention with exclusivity, not a way of extracting the maximum amount of revenue from everyone who finds value in your IP in some way. For example, you invent the next big thing in facial recognition. You should be able to patent your invention for that purpose to allow you to use it in your own or your partners / customers products with exclusivity for a set period of time. If your competitors want to use it too, then the patent affords you the control to allow or deny their ability to use your invention to compete with you for that specified purpose for a limited amount of time. Just because you have a patent doesn't mean you should be able to prevent someone else from using your original idea in a new and creative but totally non competing way, like say in the autofocus function of a video camera. What you shouldn't be allowed to do is to patent something for an abstract use case and never actually use it for anything of value, instead you use the patent as a tool to extort royalties from others that want to use this IP, and would inevitably have invented the same thing but were not the first to do so. This behaviour of holding IP to ransom prevents other people from being able to take a good idea and turning it into something even better, or combining it with other ideas and using it in a way the original creator could never have dreamed of by themselves. It's a bit of a grey area

Re: appendToResponse
Atli,
could you try to put your signin logic earlier in invokeAction ?
In the request /response loop , you would be more comfortable to
decide which page to choose for the response, see :
public WOActionResults invokeAction(WORequest aRequest,WOContext
aContext)
I think it's too late, in appendToResponse, you can only append and
not replace by another one. ( perhaps it's possible , but i don't
remember )

Re: Applet + WO
Shravan, another way , if you don't use component , you avoid cache trouble. Would it be difficult to extract the code ( used to receive for the uploaded file) in your component and put it in a DrectAction ? With WOActionURL you can generate the url for the action for the Applet, the Applet may upload files directly to a dedicated direction action, and then avoid to fill the cache ? What did you have in your component that a direction action may needs and not have ? HTH, Stephane PS : just an idea, but not sure a good idea ..

However, I do not see this as option for solution, as in our app, we do not have any upload limit, i.e., no limit on how many number of files can be uploaded per click.

Re: Identical requests make my csv component always returns the same content
Hi Yung-Luen,
have a look on the following method : disableClientCaching ---
Class WOResponse
http://developer.apple.com/documentation/DeveloperTools/Reference/
WO541Reference/com/webobjects/appserver/
WOResponse.html#disableClientCaching()
You can override appendToResponse in your CSVReport page and invoke
disableClientCaching,
something like :
public void appendToResponse(WOResponse aResponse, WOContext
aContext) {
aResponse.setHeader(application/vnd.ms-excel, Content-
Type);
super.appendToResponse(aResponse, aContext);
aResponse.disableClientCaching();
}
About HTTP headers : http://www.w3.org/Protocols/rfc2616/rfc2616-
sec14.html
If your trouble still persist , particularly with browser like IE,
perhaps you could try to add a query string with time and milliseconds,
on the client-side. But as usual , less you do with JavaScript,
better you are ...

Hi folks,
I have a page with a list of data entry using ERXDisplayGroup and a
Download Report link which returns a csv-formatted detail of
selected entries.
The link bound to an action looked like:
public WOComponent generateReportFile() {
CSVReport n = pageWithName(CSVReport.class);
n.setDataEntries(selectedEntriesArray());
return n;
}
When user clicked a data entry in the list, I'll toggle it in
selectedEntriesArray using Ajax framework in Wonder.
When the first time user selects some entries and download the report
file, it's fine.
However, no matter how the user modify the selection set after the
first download, they can only get files with the same content as the
first downloaded one.
After investigate this problem, I find that the generateReportFile()
action were called only once at the first click of my link. Seems that
WO cached the component and return it without invoke my action because
those requests are identical. (I use Ajax so there's no whole page
refresh, I guess this is the reason why I change the selection set but
still got identical requests.)
Is there any way to avoid WO cache my component without invoke my
action?

Re: Identical requests make my csv component always returns the same content
Ok sorry,
I'm trying to help you but ...
If you put , just for test , setPageCacheSize(0) on WOApplication the
problem disapears ?
See setPageFragmentCacheSize too.
Did you have a Session ?
If yes , overriding one of the methods savePage, savePageInPageCache
or savePageInPageFragmentCache
to prevent to put in cache some of your pages based on their name may
be what you are looking for ?
You can still rely on your own API on each component , like
mayBeCached defaulting to true, and then overriding on per page basis
when you don't want caching.
If you have no session, url of your page may be cache by the browser,
then i would try to add dummy value in a query string.
HTH one more time,

Yes, I've already add this line to my class. However, my problem is
not a client side caching but a server side caching I believed.
There is a method that disable the server side caching on
WOApplication, but I hope there is some way to set it on specific
components.

Hi Shravan,
i think your trouble is the consequence of Missing Fault Handler.
Are you using propagate primary key in your model for a relationship ?
You can Google Missing Fault Handler
Read that : http://developer.apple.com/documentation/WebObjects/

Re: takeFormValuesFromRequest problem
Lachlan, your trouble comes from the bias you create between the server state and the client state. When you modify the UI via javascript, when you add the company name on the client side and show the company name, the server side doesn't know that there's a new value ? There's no elementID in the tree of component on the server side for companyName and WebObjects doesn't know he should extract a form value for that unknown key. The better thing thing to do is to extract value by hand and set it in your EO in takeValuesFromRequest ? The same sort of trouble arise when you put an action in conditionnal, changing the condition may impact the action call, Chuck explanes that very well in his book. If you remove the condition, (just for test) under Compnay Name and show/hide the field in javascript everything works better ?

Michael,
did you try the type Class Void ? something like Void.Type ?

Perhaps Java should allow 'null' as a type argument.

Can be used to call the following method which returns a String

public String testMethod() {
return “testing, testing, 1, 2, 3 ...”;

But what if the method returns void?
public void testMethod2() {

What type argument should be used to instantiate NSSelectorT?

Re: WO(Re)petition
Hi Miguel, answer below Le 3 oct. 07 à 12:42, Miguel Arroz a écrit : Hi! I know people who develop on Windows today, no problems. I know people who develop on Linux, they way the only problem is that EOGenerator does not run, but a) EOGenerator is not even made by Apple, and 2) There is a Java replacement on Wonder, I think, although I'm not sure. Also, you don't need an xServe to deploy. People are using Linux, FreeBSD, Solaris, with no problems at all. It's Java. That's the point! Yes I know but it's depend the kind of client. I have spend many years with a big one. The 5'th european inssurance company, and IBM is everywhere with WebSphere, there 's a lot of lobbying inside to kill WO. In this kind of client, you simply can't say them : the product is no more supported on any other platform than MacOS X servers, it works, but not garanteed, and we haven't got the source. This being said, I think that if your client wants to abandon WO, the problem is not in WO, but in your client. Not agree, the french WO market is so small, that every client leaving WO is a problem, It's a problem for the client but also for Apple, I think. Apple may not officially support non-Mac platforms, but we know it works, and at least Apple offers official support for their platform. Look at the open source stuff. Do they offer support for anything at all? No. Because they are opensource, if you choose an opensource framework, it's on your own risk. If you can make it work, cool, if not, who cares. WebKit is a different story, but even WebKit only became anything serious after Apple closed-sourced it for a long time, and worked alone, using their own guidelines, orientation, talent and strategy to build a decent product. They only open sourced it after being good enough, and because legally they really had to. Ok, but what did you mean ? WO is not actually clean enough ? We can wait if needed. When you say I know many developpers that wil be back on the WO side, if Apple opensource WO, but they are currently using uggly technology, just for eating., what are the arguments they present? I just prefer a growing community , I think it's a good signal for a technology. It's not enough to say oh, i don't use WO because it's not open- source.. I've never said something like that, but many clients , yes. They must say WHY. Open-source originally was a good ideia for some kind of projects, but it has a lot of drawbacks, yes you'are right again, but Apple is doing big bussiness, I hope they can afford a team for that. specially when you look at the quality of the products, because a lof of people work on it and because many times there's not a roadmap for the product. Unfortunately it has become a comercial buzzword (how ironic, isn't it?), and many people say they will only use open source stuff because it's an hype, they don't really know why. I don't call that thinking different, I don't even call that thinking. That's why I asked for argumentation to your petition. WHY do you want it to be open-sourced. Why ? to gain market share rather than loosing. Did you ever try to run WO on AIX platform ? I'm not directly speaking for myself, I'm just trying to do business with a WO(nderfull) technology. Clients are more and more afraid, tools are deprecated, we loose mulitplatform support ... and last news : Did you know that JavaClient is just supported on Leopard, but you can't anymore develop with JavaClient ? Personally I don't care, I've choose FLEX and AIR, but some clients are totaly disappointed. ( Many years of work ) Opensource is simply a kind of security for client, even if it's an illusion, artefact, it's more easy to say them don't be affraid, we have source we can try to run WO on AIX for example or whatever they wants. What will we win Most of fortune 500, 1000 would never choose a product not certified on any other platform than Mac servers. I don't want stay in small business. We will win many developers and I think it's really important. and loose with it. I'm waiting! Stephane Yours Miguel Arroz On 2007/10/03, at 09:17, Stephane Guyot wrote: Ian, David, Miguel ...

I have a dream :-)
Hi list, last night as FTO ( Fantomatic Technical Officer) , I directly report to Steve. I just dispose of only 2 minutes to convince Steve that opensource WebObjects may have a big Hallo Effect for Apple. The WO team agree with me and all WO developpers too, the challenge is big for the Community. I take the lift, door of the office is open, today's rumor says that Steve is in good mood, go. Fantomic : Hi Steve Steve : Hi Fantomic Fantomic : Well, the web is a mess , Apple can still come back in the war on the server side. J2EE is a nightmare, bad design, too much of JSR, most of J2EE projects fails. WebObjects, is simple , very light , very efficient, Steve , WebObjects is a bomb. Today the only drawback with WO is that, it's not opensource. I think we need to decide under what kind of License we can opensource WO. We need to avoid the cacophonic coding of most opensource project, we just need to keep the hand of the design and future of the technology. Anycase, today the big challenge is no more on the server side, RIA are future of the net. Steve : Fantomatic, you speaks about war and bomb, what did you have in mind, Iraqi ? Look at WebKit. Adobe is using WebKit for AIR, they are simply laughing at us. (I'm a little bit disappointed, I think Adobe is a big player on the RIA, perhaps buying Adobe would be the best thing we can do , but I can't say that to Steve. Fucking words, as a frenchy guy, I just wants to avoid the Iraqi war subject, I remember the ONU speech of the french prime minister, but in the same time I'm feeling better, Frenchy are not always saying stupid things ) Fantomatic : We needs to Think Different, WO was simply ten years ahead ot his time. (Steve's iPhone beeps. 2 minutes it's very short.) Steve : I will decide soon. Fantomatic : Great, do the right choice. I just came out, I saw the next iPhone on the desk, but it's under NDA :-) Sincerly yours, Fantomic PS : Suggested reading : http://www.artima.com/weblogs/viewpost.jsp? thread=193593 Suggested hearing : The Third Bardo , I'm Five Years Ahead of My Time http://phobos.apple.com/WebObjects/MZStore.woa/wa/viewAlbum? playlistId=261634131s=143442i=261634163 Probably my last request, my last post on the list :-) Good luck to everybody, Stephane ___ Do not post admin requests to the list.

Hello list,
After a few search in the WO documentations and experimentation, and
owe to the people who send me clue and their way of doing, i think i
found a way to have the server name, yet i hope so.
I used the WOContext request() method. As u surely know (in fact i
write this for the other newbie like me :-)) (WOContext context) is an
argument of the constructor of ur WOComponent. So i wrote a few more
line in it, to get what i want.
=== Example ===
At first u have this :
public MoviePage(WOContext context) {
super(context);
}
==
I added this :
public MoviePage(WOContext context) {
super(context);
WORequest request = context.request();
String serverName = request.headerForKey(host);
System.out.println(Server Name is :+serverName); // For
verification
}
==
after going to the MoviePage when i check the console i obtain this :
Server Name is : g-five.local.
That's what i should obtain. Then when i use the ivar serverName in a
method who built a static URL like :
String dynamicVideoUrl = http://+serverName+/folder/movie.mov;
the movie is displayed. Now i only hope that the server name is really
the apache domain name (the static one). As the http server and the
application server are on the same machine, it seems impossible to
figure it out.
Maybe the more experienced WODeveloper could tell us ?
Regards.
GM.

The EOModeler Adavantage ? / Time to refactoring job ?/ WOF longevity/success becomes a nightmare :-)
Hi list,
after almost 10 years of WebObjects/EOF , we starts with WOF1.0 and persistent, transient variables in WOComponents ... :-)
today we just have these statistics :
Number od Models : .. 43
Number of entites : 578
Number of attributes : ... .5265
Number of relationships : ..995
Number of named fetch specification : ...553
I hope my WOD statistics are goods (?) :
countModels : WOString {
value = models.count;
}
sumEntities : WOString {
value [EMAIL PROTECTED];
}
sumAttributes : WOString {
value [EMAIL PROTECTED]@sum.attributes.count;
}
sumRelationships : WOString {
value [EMAIL PROTECTED]@sum.relationships.count;
}
sumFetchSpecificationNames : WOString {
value [EMAIL PROTECTED]@sum.fetchSpecificationNames.count;
}
We have many applications but most of them doesn't use all the entities, and i'm currently looking for how to determine, to define a way to load only required models and entities. We have custom way to load all models and EOs in sharedEditingContext but it's not very fine grained, to do that we loads all entities and dynamically adjusts from properties files, it's perhaps very bad idea.
How you handle packaging of classes and models ?
For historical reasons we puts all the models in one subproj, because Project Builder/EOModeler doesn't like so much inter models relationships in differents projects. Does Xcode in 5.3 do a better jobs ? ( No more stupids , Clear Destination Entity, I will Find it , questions ? )
Perhaps it's time to write a custom EOModelGroup ?
In one models we have 137 entities, and 137 classes , but in fact it's just single table mapping, we only have one intelligent class, and 136 stupids classes, that only have special Type ( it's a kind of intelligence , but it's still lot of noise ).
In another models we have all the business logic of the hierachical Business Units, but in fact we have dedicated WO instances restricted to specials Businness Units. and don't have restriction o each instance. What is the better solution, share th code, share the model and dynamically adjusts with restricting qualifiers at run-time ?
Is there a smart way to handle such situations ?
995 relationships implied some complexity in the graph of objects (:-()), how do you handle such spaghetti situation ?
For the moment i'm just begining to investigate and do nothing except asking myself questions and tests... (EOClassDescriptionNeeded ?)
but any suggestions, experiences are wellcome.
Stephane
PS : OK, small is beautifull , but the reality becomes a nightmare :-)
EOModeler is very buggy but we are not with Hibernate and the by hand doing made .hbm.xml configuration files ;-)
