Re: Proper place for functions in KVC paths?
Hi John, On 30/08/2006, at 7:20 AM, John Larson wrote: Hello, I think the api implies they all work and will have differing outcomes depending on what you would like to 'sum' or 'count' etc. e.g., Consider the keypath: 'company.people.accounts.totalLiability'. You can think of the keypath as a tokenized string that is evaluated recursively through the elements toward the end of the string and the @operators are looking for scalar values to iterate over and accumulate. So, for company.people.account.totalLiability where people is the only array, then [EMAIL PROTECTED] would produce the sum as desired. Suppose, however, that each person had multiple accounts. The following would also be valid: [EMAIL PROTECTED]@sum.totalLiability. The point of this was to not leave the thread with the idea that there can only be one @operator in a keypath. This is the kind of thing that WOBuilder provided without thought ;-) I was sure it was possible but had a mental blank.

Re: custom display for WOToManyRelationship destinationDisplayKey
Hello Fabian, Hi Xavier, So I tried WOApplication.application().resourceManager ().stringForKey(anAttributeOfTheEntity, NameOfTheStringFile, null, null, null) but even if it compiles fine, I just get null when the values are displayed in the page. So I'm assuming WOResourceManger isn't suppose to work in a Framework...but I may be wrong. Later I'll also need to pass a value for the available language, and I'm not sure on how to bind that in the WOToManyRelationship.. So my second guess was to create the method that got to the .string file directly inside my component.java file. But this time I don't know what to put for anAttributeOfTheEntity in stringForKey(anAttributeOfTheEntity, NameOfTheStringFile, null, null, null) I really don't know how to do this:( Well, maybe I don't get your question, but the documentation reads: public String stringForKey(String aKey, String aTableName, String aDefaultValue, String aFrameworkName, NSArray aLanguagesList) aKey - attribute in the receiver's request aTableName - the string table aDefaultValue - returned when no value is found aFrameworkName - name of the framework in which the resource resides aLanguagesList - list of languages in specific order Returns: a localized string from the string table aTableName http://developer.apple.com/documentation/Webobjects/Reference/API/ com/webobjects/appserver/WOResourceManager.html#stringForKey (java.lang.String,%20java.lang.String,%20java.lang.String,% 20java.lang.String,%20com.webobjects.foundation.NSArray) Yes, and if aLanguagesList is null, it will pick up the available key anyway. So this is correct and work as expected in my application, but when I try to use it in a framework, it seems like it doesn't get any value:( If localization is somewhat important to you, you should look at ERXLocalizer and ERXLocalizedString in WOnder: http:// www.mdimension.com/~wonder/api/er/extensions/ERXLocalizer.html I'll have a look for sure, I just want to know the built-in way to do it:) Xavier ___ Do not post admin requests to the list.

UTF8, MySQL, and JDBC
I'm having some trouble implementing UTF8 with webobjects. I've tried very hard to dot my i's and cross my t's in this process but I'm apparently missing something. The problem doesn't seem to occur on smaller varchar fields. It only occurs in text fields. (is this leading me astray?) Using CocoaMySQL I've verified that UTF8 data is being properly stored in this text field. It seems that WO is having a hard time submitting and retrieving it as utf8. I've set the following additional keys in my JDBC connection which should make a utf8 connection. useUnicode=true characterEncoding=latin5 Is there a way to verify the connection character set? The pages are definitely being created in utf8. Any ideas? I'm obviously very confused. thanks, matt ___ Do not post admin requests to the list. They will be ignored.

RE: Subclass final class (Boolean) ?
On 29/08/2006, at 4:04 AM, Chuck Hill wrote: On Aug 27, 2006, at 7:28 AM, Ken Anderson wrote: OK, I'm a little annoyed here because I find the whole concept of 'final' to be ridiculous. I can see the use of this concept. For example, you may have a legitimate reason for making your LicenseEvaluator class final. But the Java API writers have used it with wild conceit. Our String is so perfect, nobody will ever need to extend it!. Well, that and the fact that String might be a perfectly good basis for another class. Ok, so give me any reasonable idea. Final classes have several different adventages/disadventages. The most important advantage is that final methods can be easily inlined after class is loaded into JVM, especially by JIT. Another thing is that normally good practice is to make esential classes in frameworks final. That guaranteees that whenever you will use that class it will behave the same way. Another point for making String as final is that java makes many different opitimizations for this class which base on the internals of String and assurance of it's behaviour. You can always use composition instead of inheritance - marking class as final forces you to do it. No, you can't always use composition instead of inheritance. Many API methods take a String and your composited class won't qualify. I'm saying about your design - you can always use composition instead of inheritance in your design, when class is marked as final. Still I don't see resonable case when I would like to extend String especially because it is immutable so what is the real need that you would like to extend it? That and the rampant use of private methods (as opposed to protected) mar many Java APIs. I agree with that too. I hardly ever use private, always preferring protected. Not being able to get at things in subclasses goes against the open-closed principle, which states why you would want to subclass in the first place rather than use as a client. And that's back to Ken's original point, because final/private goes against the flexibility and openness of the OO paradigm. (In fact the whole public, package-level, protected, private scheme cannot express intricate relationships between classes where some are public, but others may be support classes in one or more other packages.) That's also interesting. How can it be that final/private goes against the flexibility and openness of the OO paradigm? If methods behavior is essential for other methods in a class, changing it's behavior needs also changing all the methods that use it. That's way sometimes it's good or even preferred to make a method private. If you really have to access private methods - change you design - if you still need it because you are a hacker and just do that for fun - use reflections and change access level to public. That is conceit you are describing, not good design. Good design is thinking, I will build this clearly, and encapsulate the concepts, and implement it in terms of these concepts. Private API is the conceit of a Designer thinking, I know better than any Developer who will ever use this class, so I will keep the dangerous parts safe from their unskilled hands. Public methods are the API for the end users of the class. Protected methods form the API for extenders of the class. Private API is just inconsiderate unless it is hiding some particularly brittle and nasty implementation. What if you don't need to change a private method, but only call it? You can't. So if you subclass a class with many private methods, you end up having to re-implement much of it rather than tweak the bit you were concerned with. I don't see it the same way. This is true that sometimes people overuse final for classes that are perfectly good candidates for extending them, but it is not the case for classes like Boolean or String. I'd also mark them final because those classes are immutable and are simply primitive types wrappers (like Integer and so on). I think other way when marking classes final: Nobody will be so stupid to extend this class, so I will use final here to say compiler and runtime system that this will not happen. Private API are for framework/library/application implementator use - you should even know that there is any method names X when it's private. Private API's are private because implementators want to have some internal structure that they will be able to easily change and usually private API changes a lot. Normally I'd like to have some parts private to do not think each time I change internals (because of optimization or whatever) if someone don't relay on this. Do you also think that private fields are something to protect from stupid programmers? ___ Do not

Re: Wonder Ajax Application Example
Can't address the problem directly, but I have been having some similar IE-related fun in RubyOnRails recently - IE is very poor at allowing editing of table data in the DOM. Basically you cannot modify table rows in a table using _javascript_. There are workarounds - using TBODY tags around your rows seems to help, for example. I have no idea if this is relevant to the WONDER AJAX stuff, but it might give you a clue if your AJAX calls are returning table rows. I ended up rewriting my page using DIVs instead of tables to get round this problem (couldn't get the TBODY stuff to work the way I wanted). Oh, and having form elements in your AJAX response causes some weirdness on IE too.Good luck, hope that helpsGeoffOn 29/08/06, jerry porter [EMAIL PROTECTED] wrote: Hello,I downloaded Wonder resently and I worked through the example drag and drop list and added thefunctionality to an application I am working on.Works great, however, it appears not to work on I.E. on windows.

Re: Subclass final class (Boolean) ?
There are hundreds of reasons to extend String. Maybe you want strings to be able to archive in a special way? Maybe you need them to be initialized from a special type?Yes, in those cases, you could use a static helper function. Inelegant, but functional.More importantly, there are often times when the instance implementation and the static class methods must be implemented in the same class. This is the case that I had that originally started this thread. The problem was, an existing tool took 3 parameters:1) The class name of the instance you want to use to represent something in a database2) The method ON THAT CLASS that generates the representation you want for the database storage3) The static method ON THAT CLASS that can be used to initialize a new instance from database storageThere is no way to make this work without subclassing - and that is why I don't like 'final'.Everyone - please - there are language capabilities that are good and bad depending on how you use them. There are functions people may not understand or need, while others might.

Re: directtoweb and readOnlyEntityNames rule
Okay, I'm going to take another stab at it. I think you're using the
wrong class.
From the 5.3 API, EOKeyComparisionQualifier compares a named
property of an object with a named value of another object. For
example, to return all of the employees whose salaries are greater
than those of their managers, you might use an expression such as
salary manager.salary, where salary is the left key and
manager.salary is the right key.
I think you should be using EOKeyValueQualifier, which the API states
that it compares a named property of an object with a supplied value,
which I believe is what you are doing. Based on this, You should
rewrite the rule as:
{
author = 50;
class = com.webobjects.directtoweb.Rule;
lhs = {
class = com.webobjects.eocontrol.EOKeyValueQualifier;
key = session.noEdits;
selectorName = isEqualTo;
value = 1;
};
rhs = {
class = com.webobjects.directtoweb.Assignment;
keyPath = readOnlyEntityNames;
value = (User, Group);
};
}
The reason the rule you wrote is not being triggered is that there is
no object 1 and 1 certainly doesn't have named value so the lhs
is never True.
Again, I'm pretty new to rules writing, but I think this is correct.

Re: custom display for WOToManyRelationship destinationDisplayKey
Hi Xavier, One last thing, if I want to pass the languages NSArray from the the application (displayDestinationKey) to the localizedName method in the framework, how would I do that? I can only guess that you'll want to pass in the session's languages: http://developer.apple.com/documentation/Webobjects/Reference/API/ com/webobjects/appserver/WOSession.html#languages() I'll guess your next question will be how to access the session from the method in your framework? WOnder lets you get it via http:// www.mdimension.com/~wonder/api/er/extensions/ ERXExtensions.html#session(). I don't know any similar API in standard WO that would let you access the session without passing the context around. Anybody? cheers Fabian ___ Do not post admin requests to the list.

Re: custom display for WOToManyRelationship destinationDisplayKey
No, but Wonder just sticks it in a ThreadLocal variable, which you could easily do with non-Wonder-WO also. Just make sure to clean up after yourself at the end of the request. ms On Aug 30, 2006, at 10:15 AM, Fabian Peters wrote: I'll guess your next question will be how to access the session from the method in your framework?

Wonder AJAX Drag/Drop
Hi List, I found the following behavior in DragAndDropExample component: The method in the action binding in the AjaxDroppable is called only once for each AjaxDraggable that is dropped in the AjaxDroppable. For example if you drag and drop the draggable #1 into drop area #1 something is printed in the console, the next time that you drag and drop draggable #1 into drop area #1 nothing is printed. I don't know if this behavior is normal, maybe there is another binding that needs to be set to change this behavior. If somebody know how this works please let me know. Thanks in advanced ___ Do not post admin requests to the list. They will be ignored.

Re: directtoweb and readOnlyEntityNames rule
I am glad I could help!
This type of problem seems to be VERY typical of D2W and D2JC (and
likely D2WS as well). The documentation is often either incomplete or
just pain wrong. Digging through the API and examples of things that
do work is about the only way to get by. With that said, once you
figure out the correct way to do things, it is absolutely amazing
what can be done without writing a bunch of Java code.
If there is a place in any of the documentation that led you astray,
please point it out. I'm on a crusade to make D2JC (and D2W) much
more friendly and less mysterious and therefor used more widely.

nasty cusses I muttered about D2W.
Thanks a whole lot for your help!

Okay, I'm going to take another stab at it. I think you're using
the wrong class.
From the 5.3 API, EOKeyComparisionQualifier compares a named
property of an object with a named value of another object. For
example, to return all of the employees whose salaries are greater
than those of their managers, you might use an expression such as
salary manager.salary, where salary is the left key and
manager.salary is the right key.
I think you should be using EOKeyValueQualifier, which the API
states that it compares a named property of an object with a
supplied value, which I believe is what you are doing. Based on
this, You should rewrite the rule as:
{
author = 50;
class = com.webobjects.directtoweb.Rule;
lhs = {
class = com.webobjects.eocontrol.EOKeyValueQualifier;
key = session.noEdits;
selectorName = isEqualTo;
value = 1;
};
rhs = {
class = com.webobjects.directtoweb.Assignment;
keyPath = readOnlyEntityNames;
value = (User, Group);
};
}
The reason the rule you wrote is not being triggered is that there
is no object 1 and 1 certainly doesn't have named value so the
lhs is never True.
Again, I'm pretty new to rules writing, but I think this is correct.

out of memory (wo 5.3)
Hi All, I'm getting out of memory exceptions in my app. I do need to go through it and see if there is anything I can do to manage memory better, but until then, I tried increasing the memory of the JVM. I did it by adding -Xmx256M -Xms128m to the Additional Arguments section of the apps configuration in Monitor. When I check the running processes using ps axwww | grep Xmx I see my app but it has two occurrences as you can see below. java -XX:NewSize=2m -Xmx64m -Xms32m -DWORootDirectory=/System - DWOLocalRootDirectory= -DWOUserDirectory=/System/Library/WebObjects/ JavaApplications/wotaskd.woa -DWOEnvClassPath= - DWOApplicationClass=gov.maine.oit.BailMonitor.Application - DWOPlatform=MacOS -Dcom.webobjects.pid=9181 - DNSDebugLevel=NSLog.DebugLevelCritical -Xmx256M -Xms128m I'm questioning which of those is taken. I would think that the arguments are checked as they are encountered and that the last one is the one used but I don't know any way to be sure. Can anyone confirm that the Additional Arguments section in Monitor is the right place to put that and that it is the last argument that takes effect?

The second one should win, though you can print Runtime.getRuntime ().maxMemory() in your app startup to be sure.

Re: out of memory (wo 5.3)
Marc, If you display dynamic images (e.g. from generated from a database) then I would recommend looking there for the source of the memory leak. Under certain circumstances the resource manager fails to free up the resources. I no longer use WOImage and WOActiveImage. Instead I created a custom image element starting from code someone on this site donated. That fixed the memory leak for my application. -tom On Aug 30, 2006, at 1:00 PM, [EMAIL PROTECTED] wrote: Date: Wed, 30 Aug 2006 12:53:46 -0400 From: Marc Respass [EMAIL PROTECTED] Subject: out of memory (wo 5.3) To: WebObjects-Dev Apple webobjects-dev@lists.apple.com Message-ID: [EMAIL PROTECTED] Content-Type: text/plain; charset=US-ASCII; delsp=yes; format=flowed Hi All, I'm getting out of memory exceptions in my app. I do need to go through it and see if there is anything I can do to manage memory better, but until then, I tried increasing the memory of the JVM.

Re: Wonder Ajax Application Example
I also had to rewrite my tables using divs to get it to work right.

Removing UTF8 characters seems to prevent it, but sometimes it'll save a multi-be character anyway. Its complaining that the column isn't long enough but its definitely long enough. Its a text field which should be able to store some 65k characters. Any ideas? I'm stumped. thanks, matt [2006-08-30 14:29:51 EDT] WorkerThread0 evaluateExpression: com.webobjects.jdbcadaptor.MySQLPlugIn$MySQLExpression: UPDATE abExhibition SET description = ?

If you still have some issue, you should be checking how to convert the text encoding on existing field in the database as they were probably not UTF-8 at the beginning...maybe try to dump the database, drop it recreate it 'making sure it's UTF-8 thanks to the my.cnf parameters).

Javascript in a framework
Hello all,
I am calling a javascript that resides in a new framework that I have
just created.
CalendarPopupJavaScript: WOJavaScript {
scriptSource = calendar.js;
hideInComment = true;
}
The html generated reads:
SCRIPT language=JavaScript src=/cgi-bin/WebObjects/
FrameworkTest.woa/wr?
wodata=ERROR_NOT_FOUND_framework_*null*_filename_calendar.js/SCRIPT
Can you call a javascript file that resides in a framework using
WOJavaScript?

Re: Javascript in a framework
No, surprisingly this is not supported. File a bug.
In the meantime, you can implement your own. :-)

Working example of EOModel and OpenDirectory
Hello, I'm revisiting the idea of adding LDAP to my WO application. However, I'm unable to get things working based on the Developer example.

Re: Restore and Save Session
Hello Chuck; I am a little confused here as at (2) there is no context in which to restore/save the session. I assume in the case of the component request handler, the context is actually created at (2), but I am creating a system that uses 'WOAction' so I assume the context must be being created at (1) and thus I think the session restore and save must be done at that point as well? cheers. I'm wondering, when one is writing a request handler, where should the session restore and save be located? 1) WOAction.performActionNamed(...) 2) WORequestHandler.handleRequest(...) Anybody know where Apple does this? The second one. See page 167. ;-) ___ Andrew Lindesay www.lindesay.co.nz ___ Do not post admin requests to the list. They will be ignored.

EOModeler not bringing any data
Title: EOModeler not bringing any data Hi all, Something really weird happens: I use EOModeler to browse data from a view in SQL 2000, and it shows no data. But if queried through DBVisualizer or Enterprise Manager, I can see data. Following is the adapter setting, and there is no complaint about it by the EOModeler: URL - jdbc:microsoft:sqlserver://serverName:1433;DatabaseName=PDSDevel;selectMethod=cursor Driver - com.microsoft.jdbc.sqlserver.SQLServerDriver Also, with the same adaptor setting, Im able to retrieve data from other views or tables in the same database. I wonder what might be the problem. Please advise. Thanks a lot! Wen ___ Do not post admin requests to the list. They will be ignored.
