Re: model insights (inheritance)

2015-10-28 Thread Alexander Spohr

One Entity for person. If you have more than 2-3 attributes in Employee or 
Donar make them own entities as well otherwise just put the attributes into 
Person.
An Employee might become a Donar anyway ;)

Subclassing in the model tends to give you problems later on.

 WORedirect uses HTTP status code 302 which makes the browser using GET. What 
 you need is HTTP status code 307.
 
 So, write your own subclass of WOCompnentent with a setter method for the 
 URL to redirect:
 
 public class MyRedirectComponent extends ERXComponent {
 private String url;
 public MyRedirectComponent(WOContext context) {
 super(context);
 }
 public void appendToResponse(WOResponse aResponse, WOContext 
 aContext) {
 aResponse.setHeader(this.url, location);
 aResponse.setStatus(307);
 }
 public void setUrl(String url) {
 this.url = url;
 }
 }
 
 The method that submits your form should look like this:
 
 public WOActionResults submitAction() {
 MyRedirectComponent nextPage = (MyRedirectComponent)
 
 pageWithName(your.app.components.MyRedirectComponent.class);
 nextPage.setUrl(http://YOUR_REDIRECT_URL;);
 return nextPage;

Re: Redirect from Spring MVC application to WebObjects application

The tab's window would need to have a name that you can address in your a tag
as target=myappwindowname. Then it will open the WO-app in the old, named
window.
You might be able to set that name either when you open your WO-app’s window
(using a target link). Or you could try to set it using JavaScript from within
your WO-app. I am not sure if the latter is possible.

Please be aware that this bug might kill your database after a while!

At least using PostgreSQL, the database will keep all changes since the start

it never will be.

To avoid this we append „?useBundledJdbcInfo=true“ to all database urls.

Re: Need help in building a pretty complex EOQualifier

2013-12-12 Thread Alexander Spohr

Hi Markus,

you need a GROUP BY HAVING COUNT because one DocumentText can not satisfy your
qualifier.
Unfortunately this does not work with a common qualifier.

I once modified PostgresqlExpression to allow for a GROUP BY:

// added by atze to support GROUP BY
public void prepareSelectExpressionWithAttributes(NSArray nsarray, boolean
flag, EOFetchSpecification eofetchspecification)
{
super.prepareSelectExpressionWithAttributes(nsarray, flag,
eofetchspecification);
String aGroupBy =
(String)eofetchspecification.hints().objectForKey(GROUP BY);
if(aGroupBy != null)
{
EOAttribute anAttribute =
EOModelGroup.defaultGroup().entityNamed(eofetchspecification.entityName()).attributeNamed(aGroupBy);
String aDefinition = (anAttribute.isDerived() ?
anAttribute.definition() : anAttribute.columnName());
setStatement(statement() + GROUP BY + aDefinition);
}
}

Maybe that helps a bit.

On first sight it looks pretty simple, but the more I think of a solution the
more confused I become. Can someone help me build a qualifier for entity
Document please:

Model:

Document ---DocumentText---Text

DocumentText is NOT a simple many2many join but has its own attributes. When
I create a Document I assign a pre-defiend set of Text objects to it. This
means I create a number of DocumentText objects each pointing to one Text.
These DocumentText objects are presented to the user as a list of
attributes of a Document. The user then specifies a textual comment (for
the field DocumentText.COMMENT_KEY) and a status value (for
DocumentText.STATUS_KEY) on any one or more of these DocumentText objects.
Upon save I update those 2 or 3 or 4... DocumentText objects accordingly. For
many of them the user does not enter anything (status is a known default,
comment is empty). This all works.

Now comes the qualifier to retrieve Documents: The user sees a D2WQueryPage
for the document properties with an embedded property level query component
that presents the full list of possible DocumentText objects with their
status and comment fields. A typical scenario could be: the user wants to
enter a comment query for the second assigned text (that's Text A) and/or
picks a query value for the status of the 7th assigned text (this could be
Text B). Upon executing the query the user expects to retrieve a list of
Documents that fulfill all given criteria. In this example the user wants to
see all Documents where the assignment to Text A has comment x AND the
assignment to Text B has status y.

I have this working for the case where the user only gives one search
criterium but I cannot figure out how to construct the qualifier for the
combination. An OR qualifier returns all Documents where any one DocumentText
is satisfied whereas an AND qualifier returns nothing. I do understand those
two cases. Mind you the top level entity must be Document, because that's
what the user works with and queries against. In my property level query
component I have set-Methods for the status and the comment values on the
DocumentText loopvar. These methods retrieve the displayGroup qualifier and
manipulate it. But not knowing how the final qualifier should look I am at a
loss.

Thanks for any help

Re: Session timeout when performing an action

2013-10-15 Thread Alexander Spohr

Did you check /WebObjects/WOAdaptorInfo?
What is the dead time?
Do you see a lot of active requests?

dominique.schoenenber...@nagra.com:

 Thanks, 
 
 My parameters are (bigger):
 
 HTTP Adaptor Settings:
   Load Balancing scheme: Round Robin
   Send Timeout: 1200
   Receive Timeout: 1200

Do you have requests that take longer than 20 minutes?


 The page seems related to an http error 500.

Is it a 500 or another 5xx?


 Is any way to avoid the adaptor to give the request to another instance if 
 one instance is too slow to respond because this seems no helping because at 
 the end it causes a Session timeout error.

This would just hide your problem. You need to fix it.


 I need also to say that when the user get a untimely Session Timeout, there 
 is not waiting time (We got the session timeout just after the click on a 
 button). I would expect some retrying before returning an Session timeout 
 error if it is due to a instance not responding.

The apache has already decided that your instance is dead because it did not 
answer in time. So it just kicks your request to the next instance.

Is the editing context that you saveChanges() on the same as your objects()’s?

How do I tell the object that the attribute has changed so do an update on

Re: Binary Plist generation very slow

2012-12-10 Thread Alexander Spohr

Never use dicts or arrays as a hashtable’s keys!

I removed the uniquing of dicts, arrays and sets. I now use an int based hash 
table with object.hashCode() as the key. My binary property list generation is 
now faster than the string based version.

The test file is a 11MB string based property list, run over a 100 times each.
Duration: 15805ms NSPropertyListOpenStepFormat
Duration: 10084ms NSPropertyListBinaryFormat_v1_0

If java could provide the address of an object I would use that and unique the 
collections again. The address would be a nice hash key. Unfortunately you 
don’t get addresses in Java and the hashCode() of collections are unusable.

Original file (contains lots of spaces):

Re: WOComponent Function Call Order

2012-12-10 Thread Alexander Spohr

WO runs from to to bottom of your page. So it should work.

A better way would be to do the calculations in appendToResponse() before you 
call super. Then all will be set before the page is rendered.
If you can not do that because of your loop, you could do it in the 
displayedObjects call. Or in a method that calls displayedObjects and returns 
after your calculation for this item.

   • Functions timeConsumingCallA() and timeConsumingCallB() are, as their

   • Function callDependingOn_A_and_B() depends on the results of the two

 Is there any guarantee that the two function calls (timeConsumingCallA,

 callDependingOn_A_and_B() so I can set and depend on instance variables 
 $timeConsumingCallA_result and $timeConsumingCallB_result in the

 If not, I can see a number of ways I could myself make sure the calls are

 a Wonder/WebObjects strategy to approach this.

Re: Automatic Long (8 byte) Primary Key?

 I need an entity to have a long (8 byte) primary key.
 How do I tell EOF to generate it from a sequence as it does with 4 byte keys?


Now this gets strange.
I changed the pk to prototype id (int4) because I could not get EOF to call my 
primaryKeyDictionary(boolean). But EOF just ignores all inserted objects of 
this class. It just does not generate a pk - but tries to save them to the 
database anyway.

What I see:
1. SELECT NEXTVAL('Player_seq')
2. SELECT NEXTVAL('Avatar_seq')
3. INSERT INTO Player
4. INSERT INTO Avatar
5. INSERT INTO Gear
6. exception

The question here is why EOF isn’t getting the pk for Gear - but tries to save 
them. I don’t see any difference in the eomodel’s plists. It has a single pk 
that is not an attribute and not null, like all other tables do.
Looks like it thinks that I fill the pk. But the attribute is non-null, why 
does EOF save the whole record then? The pk attribute seems to be invisible to 
EOF.

Any ideas?

 If we are contemplating doing work, shouldn't we consider going straight for

 productive. Only use OR-mapping for old systems that we must interface with 
 but new work should consider the advantages of being pure objects, all the

 Everyone has success stories. You can write a great app in PHP if you really

 achieve their success and if we'd enjoy doing it in a similar fashion. For us

 UPDATE IP_DATES_OUVERTURE_DOM SET IP_DATES_FIN_DOM = ? WHERE (...) 
 withBindings: 1:2012-02-21 23:59:00(ipDatesFinDom)
 - the user request the same date
 - the jdbc driver fetch the date as 21/02/2012 23h59 (no tz info at this 
 level)
 - the adaptor creates a NSTimestamp with 21/02/2012 23h59 (GMT)
 - the formatter (configured with tz = GMT+11) shows : 22/02/2012 10h59 ...
 
 Something is obviously wrong with this setup, either :
 - the jdbc driver should not convert to GMT+11 when inserting, the db then 
 stores only GMT dates
 - the jdbc driver or the adaptor should convert back to GMT when reading the 
 date from the DB
 
 Any hint is welcomed,
 
 Thanks !

Re: Limit to the number of instances under JavaMonitor

 Does anyone know if there is a limit to the number of instances you can run

There is a limit in the WebObjects adaptor but that only hits the web server.


 My new instance dies silently. No log, just a new Death. I can start the 
 application from the command line. After trying everything I could think of, 
 I stopped an instance of another application, and tried again. This time it 
 works.

Did you try to start it with the exact parameters from monitor? (after removing 
the projectPath()-thingie)
Hitting any OS or connection limits?

 The number of instances is 52.

We currently run more than 500 instances for 21 apps on six machines, with one 
monitor. The biggest apps use 48 instances. When we bounce we double the 
instance count for a short time. No problems.

 Hi, All
 
 I'm having some weird behaviour and have spent the last weekend trying to 
 figure out what is going on.  Here is what's happening:
 
 I have an EO record that has a number of fields including foreign keys. I 
 run the application on my machine or on a Mac Server and edit a record by 
 changing field values, including selections in different popups to change 
 the foreign key values.  I verify that the changes have been made by using 
 a SQL application called Froq App to look directly into the database.
 
 Now the weird thing is that sometimes the data is not changed in the 
 database.  I'll log out and then back into the app and make the exact same 
 changes and this time it works.  This completely scares me and now I have 
 absolutely no faith in what the application is saving.
 
 Any one have any clues on why this might be happening and what I can do to 
 figure this out.  I'm completely stumped. :-(

Re: [SOLVED]: Is JDBCAdaptor generating the wrong SQL for fixed length character columns?

2011-11-10 Thread Alexander Spohr

Hi Chuck,

you have to use useBundledJdbcInfo=true with PostgreSQL. Otherwise your 
PostgreSQLAdaptor will hold an open transaction into the database. That will 
prevent commits from getting closed and written (kicking the old values), 
therefore bloating your database and finally kill your performance.

We learned the hard way.

 Hi folks!
 
 
 For reason not to be discussed here my coworker has created a PostgreSQL 9 
 database table like follows:
 
 CREATE TABLE systemmessagecontent
 (
 id integer NOT NULL,
 language character(2) NOT NULL,
 message text NOT NULL,
 subject character varying(255) NOT NULL,
 systemmessageid integer NOT NULL,
 CONSTRAINT systemmessagecontent_pkey PRIMARY KEY (id),
 CONSTRAINT systemmessagecontent_systemmessage_fk FOREIGN KEY 
 (systemmessageid)
REFERENCES systemmessage (id) MATCH SIMPLE
ON UPDATE NO ACTION ON DELETE NO ACTION
 )
 
 The interesting point here is column language which is a two character 
 fixed string. 
 
 In the corresponding EOModel the property for this has char as External 
 Type and an External Width of 2 and no prototype (since there is nothing 
 matching).
 
 
 
 When running the application and trying to update that property/column the 
 following SQL is generated:
 
 Nov 08 18:28:34 BKAdmin[5] DEBUG NSLog  -  === Begin Internal 
 Transaction
 Nov 08 18:28:34 BKAdmin[5] DEBUG NSLog  -  evaluateExpression:

 3:48(systemMessageID)
 Nov 08 18:28:34 BKAdmin[5] DEBUG NSLog  -  === Commit Internal

 Remarkable here is the ?::char Obviously this is a cast into a single 
 character type of PostgreSQL. 
 
 see http://www.postgresql.org/docs/9.1/interactive/datatype-character.html 
 table 8-5 for this.
 
 
 
 Correct would have been to use character(2) or char(2) as my tests with 
 PGAdmin revealed:
 
 At first I fired the following SQL:
 
 UPDATE SystemMessageContent SET language = 'de'::char WHERE (id = 28::int4 
 AND systemMessageID = 48::int4)
 
 The result was the same like the one from the WOApp itself, after updating 
 the database contained this: d 
 
 
 When I changed the query accordingly ('de'::char to 'de'::char(2)) I got 
 what I expected:
 
 UPDATE SystemMessageContent SET language = 'de'::char(2) WHERE (id = 
 28::int4 AND systemMessageID = 48::int4)
 
 After this the database  contained a de.
 
 
 Trying to use char(2) as External Type in my EOModel (instead of char) 
 I've got the following exception:
 
 Nov 08 18:40:36 BKAdmin[5] WARN  NSLog  - *** JDBCAdaptor : no type 
 info found for char(2)
 Nov 08 18:40:36 BKAdmin[5] DEBUG NSLog  -  === Begin Internal

 information for external type 'char(2)' in attribute 'language' of entity 
 'SystemMessageContent'.  Check spelling and capitalization.
 
 
 Now I think that maybe char was the right External Type to begin with. 
 Only the JDBCAdaptor did not respect the external with of 2 and did not 
 mangle char into char(2)
 
 
 Is there something I can do about this?
 
 Adding the following to PostgresqlPlugIn.framework/Resources/JDBCInfo.plist:
 
  character = {
  defaultJDBCType = (
  CHAR

  createParams = 1;
  maxScale = 0;
  minScale = 0;

CLOSE_WAIT when database is offline

2011-10-17 Thread Alexander Spohr

Hi list,

we have a rather busy WO-service. Sometimes one of our multiple database 
servers fails and CLOSE_WAIT shows its ugly head and kills the performance.

What I think the problem is:
- WebServer asks AppServer for data
- AppServer tries to connect to db
- more requests come in
- AppServer tries to connect to db
- more requests come in
- AppServer tries to connect to db
- more requests come in
...
Then after a while the WebServers close their side of the connection but the 
app connection threads still wait in queue for the database. So the app never 
acknowledges the close and we slowly die.

Is this what happens?
Can we do something against it?
A delegate method perhaps, to throw an error if we can not connect to the db? 
(And of course retrying later to reconnect - after all the database will come 
online again)

Any pointers are welcome,

atze

Our setup:

- Webservers know every appserver and ask each for running instances.
- Each appserver has wotaskd running. wotaskd restarts and shedules apps on its 
machine (that's what it is for).
- Monitor (on one machine) knows all wotaskd's and configures them.

No files involved. (Just as backup)
wotaskd's do not synchronize. They just know their own machine. (As far as I

ant build not working - again after update (Lion this time)

2011-07-21 Thread Alexander Spohr

Hi people,

I feel stupid. After the upgrade to Lion the start of Eclipse told me to 
download Java first.
I did that and Eclipse works as expected.

Now I tried to run ant from the cli. And again it fails as it did when I last 
updated Java under Snow Leopard. The last time the problem was that 
woproject.jar was placed at /Library/Java/Extensions. Removing it from that 
place helped to make ant work again.

This time there its no woproject.jar at /Library/Java/Extensions. Only in
/Applications/Developer/eclipse/plugins/org.objectstyle.wolips.woproject.ant_3.6.70244/lib/
and
/Applications/Developer/eclipse/plugins/org.objectstyle.wolips.woproject.ant_3.6.70245/lib/

But the build fails again with 
taskdef class org.objectstyle.woproject.ant.WOCompile cannot be found

I am at loss what I am doing wrong. Do I have to tell ant where woproject.jar 
is? I don’t think so as it worked fine before the upgrade. What am I doing 
wrong?
My ant is /usr/share/ant/java/ant-1.8.2

 Hi people,
 
 I feel stupid. After the upgrade to Lion the start of Eclipse told me to 
 download Java first.
 I did that and Eclipse works as expected.
 
 Now I tried to run ant from the cli. And again it fails as it did when I last 
 updated Java under Snow Leopard. The last time the problem was that 
 woproject.jar was placed at /Library/Java/Extensions. Removing it from that 
 place helped to make ant work again.
 
 This time there its no woproject.jar at /Library/Java/Extensions. Only in
 /Applications/Developer/eclipse/plugins/org.objectstyle.wolips.woproject.ant_3.6.70244/lib/
 and
 /Applications/Developer/eclipse/plugins/org.objectstyle.wolips.woproject.ant_3.6.70245/lib/
 
 But the build fails again with
 taskdef class org.objectstyle.woproject.ant.WOCompile cannot be found
 
 I am at loss what I am doing wrong. Do I have to tell ant where woproject.jar 
 is? I don’t think so as it worked fine before the upgrade. What am I doing 
 wrong?

 Hi Wonder-Community,
 
 Good News :
 
 There is now a new Version with a new Name: Wonderbar
 
 This Version will work with OS X Snow Leopard and Lion. And is a lot smaller 
 as the old one.
 
 1. After my mistake of updating my Developer ID on Apple's Site, I have now a 
 new ID.
 Because I can't make updates anymore, you have to download and install the 
 new Version.
 
 SORRY, for that.
 
 2. The new Name is Wonderbar.
 
 Installation : 
 
 You can download the new Version :

 After download, transfer with copy  paste the WO Monitor data from the old 
 Version to the new Version.
 
 Uninstall the old Version.

Re: SELECT count(*) throws - column t0.allianceid must appear in the GROUP BY?

2011-06-11 Thread Alexander Spohr

Looks like the bug is mine. I did not read the statement as i should, as the 
count(*) is an attribute.

To count an entity I add an Attribute count(*) on the fly to the entity.
This attribute seems to be still in the entity while another fetch runs.

This surprises me somewhat as I thought that my app is not multithreaded inside 
EOF.
But maybe I get an uncatched exception that keeps the count attribute from 
being removed. I'll check into that.

Sorry for the noise!

 While trying to return an EOGlobalID for a generic record, I am getting a

 EOUtilities.objectMatchingKeyAndValue(ctx, Student, studentId, sid);
   ctx.insertObject(student);  //tried with and without inserting it into 
 the context

You fetch the student into the ctx. So it is already existent in the database 
and not a new one that you could insert.
You only insert newly created objects. So that they will be saved to the 
database.

   return student;
 }
 
 Later I try to retrieve that object's EOGlobalID with the following:
 EOGlobalID globalID = ctx.globalIDForObject((EOGenericRecord) value);

You don’t show where you get value.

 The value of globalID is always null. What am I missing? 

Maybe value is null?

 My EOModel has an object called a Landing and an object called a

 Landing represents a user landing on the site. When a user comes to the 
 site, I create a Landing and associate it with the SiteDefinition so that I 
 can capture what site a user sees and what users were on a site.
 
 SiteDefinition to many Landings
 
 When I add the relationship using this:
 aLanding.setSiteDefinitionRelationship(getSiteDefinition());
 
 WebObjects decides it needs to select all Landings where the 
 siteDefinitionID equals the one I'm assigning. This is fine in dev where I 
 may only have 17 records but eventually I may have 10s of thousands of 
 records.
 
 Is this my EOModel, and if so how can I prevent it?

_Entity.java template bug?

2010-10-15 Thread Alexander Spohr

Hi list,

I have a warning in some of my classes that fullQualifier is not used after 
declaration.
The problem occurs if this if is true:

#if (${relationship.actualDestination.genericRecord})
 EOFetchSpecification fetchSpec = new 
EOFetchSpecification(${relationship.actualDestination.name}, qualifier, 
sortOrderings);
 fetchSpec.setIsDeep(true);
 results = 
(NSArray${relationship.actualDestination.classNameWithDefault})editingContext().objectsWithFetchSpecification(fetchSpec);
#else
 results = 
${relationship.actualDestination.classNameWithDefault}.fetch${relationship.actualDestination.pluralName}(editingContext(),
 fullQualifier, sortOrderings);
#end

I guess it should be using fullQualifier like this:
 EOFetchSpecification fetchSpec = new 
EOFetchSpecification(${relationship.actualDestination.name}, fullQualifier, 
sortOrderings);


Regards,
atze

Current Status of WO

2010-09-29 Thread Alexander Spohr

Hi list,

I am planning a new project with heavy load. No HTML output, just plists. Lots 
of users, small data footprint (about 10k per request). PostgreSQL.
I consider using WO and EOF again because it served me well in the last 
(almost) 15 years. But I am not sure about the current status.

The net has lots of outdated info and a some fresh about wonder. This list 
looks still very active (that gives me hope).
What is the current status of WO? Do we have a public hosted WO5.4 that Apple 
won’t pull? I left this list two years ago so if someone could please bring me 
up to speed?

Thank you for your time. It is appreciated!

Apple dropping WO from own sites

Why did Apple drop WO from the shop?
.mac has already dropped WO as me.com is something else.

Anyone who can share insights why this is so?

If Apple drops WO now from most of its own sites I get really bad

Yes I knew that part.

 Mobile.me is fully WO on the backend. The front end uses  
SproutsCore to support the new desktop-like behaviours, and calls WO  
via RPC calls.


Because Apple bought me.com and the URLs look different I thought they  
also bought the underlying software.



 Everything is OK, the world is not collapsing (although it may have  
some concurrency problems once in a while).


Thanx for assuring me :)


Before you could at least point to the URL to argue for WO. What are  
you doing now? Telling the customer that WO ist the best technologie  
you can get did work when the price was $100k, but not any more.

Usually yes. But some of them want to do support of the apps on their  
own after the hulk is implemented. So they ask for technology before  
you get the job.




Apple uses a lot of WO inside the company, they do a lot more than a
couple of years ago; it's good to have Pierre there doing a lot of
very good work in making the tool better as the responsible manager
and WO wizard.


Yes, I bow to him.


So why do you worry about it now when it's actually a

I worry since the price dropped.
I still think it the best tech out there.
Just came across the new url-style and worried.

Re: mod_gzip + WO problems

2008-06-25 Thread Alexander Spohr


Hi John,

where did you get the mod from? The version I had has a bug, it only  
scans for content-type, but not for Content-type (Capital C). Or some  
other header that WO sends with a capital.
I think you can see it because you either get two headers, or the size  
does not fit the content. I can’t remember what it was exactly.


If you fix that, mod_gzip works fine.

this has something to do with the fact that the content is being

Re: Null property exceptions

2008-06-03 Thread Alexander Spohr


Jeff,

a 1:1 always connects the pk of both tables. Otherwise it is 1:n and  
should be modeled that way.


You have modeled a 1:n and set the propagation in the wrong direction  
(assuming that the other side has a to-many relationship :)


If you want to delete the entryScoreID you have to correct your  
relationship.

Owns Destination is wrong as well. You designed your relationships

And you’ll need to set all other relationships as well before you  
saveChanges, as none of the fks allow NULL.

You're exactly right, that relationship is an owns destination

pool = Pool.fetchRequiredPool(ec, poolQual);

entry.entryScore().setPotential(0);

but now I'm getting a different validation error.  There's  
probably still something I don't have setup right for using the  
propagates primary key and owns destination options for this  
relationship, but I'm not sure what it is.  It's interesting  
that the below INSERT passes in a NULL value for the  
entryScoreID.  If it automatically creates its own entryScore  
object, shouldn't it be sending in the ID of that object instead  
of NULL?


Well, uh, how do you have it set?  Do you have any foreign key  
exposed as a class property?  If so, don't!  You can make the PK  
a class property (not saying this a good idea, just that it won't  
cause errors), but exposing an FK will cause this sort of error.

Re: odd behaviour in n:m settings in EntityModeler in WOLips

2008-06-02 Thread Alexander Spohr


Johann,

it sounds like you got it the wrong way ’round.

Am 02.06.2008 um 08:58 schrieb Johan Henselmans:

I am creating a n:m relation between two tables, called adminuser  
and admingroup, and flatten the relationship.


That would result in an n:m table, admingroupadminuser, with two  
relationships on both sides: one would propagate the primary key to  
the table admingroupadminuser, the other one would be a flattened  
one to the other table.


The master-tables (adminuser and admingroup) have to propagate their  
pk into the n:m (admingroupadminuser). admingroupadminuserhas no pk of  
its own so it has nothing to propagate somewhere.


So you’ll have these real relationships (which you switch off in the  
model):

adminuser - admingroupadminuser - admingroup

and these two flattened ones:
adminuser - admingroup



However, I am now getting verification errors in EntityModeler after  
creating the table. It says:
The relationship adminGroupAdminUsers is a to-many but also  
propagates its primary key.


This sounds strange.

I assume that turning off the propagate primary key would prevent  
creating a new record in the n:m table admingroupadminuser.


See above.


Anybody has the same experience,


No.


solutions?


I hope so :)

If yes, this will kill your cycle while the tree is rendered/comes

No it changes IN takeValues. When it gets the checkbox, your following  
conditionals are reverted. Therefore your appendToResponse drew  
something different than your takeValues gets back - after taking the  
checkbox’ value.


Not sure if I am understandable here :)

Rule of thumb:
- Never change conditionals anywhere after super.appendToRespose() and  
before super.invokeAction()!


atze


Trying to clarify:

checkbox = false;
appendToResponse draws second condition - field-ids begin with x.y.z.1

user checks box
takeValues gets checkbox and switches conditionals
the incoming values have ids beginning with x.y.z.1 (second  
conditional) but the fields in takeValues now begin with x.y.z.0  
(first conditional) - so they ignore the values as they have not the  
correct ids. Result: your objects get null values because the  
inputstream has no values for your fields.

No, do not return null but the content of the new detail-page. This

Now I also want another (new) window to open up; to achieve that my

window.open(someURL, _blank, ...) calling a method that would  
return the detail of the selected object. I guess I have to use  
WOActionURL to generate the URL used by window.open ... ?


Don’t do that. That would always be called. Then you’d have to add a  
WOConditional for the body-tag and the horror begins :)


A last question, which indeed is more HTML related : Indeed I'm  
using a wrapper component for having a consistent layout over all

Dont use onLoad. Just put the JavaScipt where (your enclosed

Hm, this could easily be overridden by an EOF specific subclass...  
An NSArray (a fault) that would respond to objectAtIndex(...) by  
firing the fault and returning the appropriate object, but would  
respond to valueForKeyPath([EMAIL PROTECTED]) by asking EOF to  
evaluate it directly. No?


EOF has no method to to count, sum, max, min and the like in the  
database.




Well, maybe I am pushing this idea way too far :)



The idea sounds good but then you had two modi operandi:
1. count rows in the db
2. count objects in memory.
I am not sure if that would be a good idea, you might get different  
results at different times.

Not sure if I understand the question. But I’d say deploy the woa

is its own app-server.


Maybe someone could point me to the advantage of using any additional

No problem. Just write up the purchase order for a copy of the WO  
5.4 frameworks wrapped in super-sexy MacBookPro packaging. Just  
$4,000. Or you can go for the more economical Mac mini packaging.  
Just $599. (that's $200 off the $799 list-price for 5.2) and you get  
a free computer to (dual)boot.



Situation in the Real World:

- No software-package, you have to buy a Mac instead that people don’t  
want.

- No support to transfer that to Win/Linux
- No clear licensing for developers using Win/Linux
- If you think the license model is „one Mac OS X license per  
developer seat“ then you still have an OS DVD that you can not use to  
install WO on Win/Linux.



The only possible _manager acceptable_ solutions (from my experience)  
could be:


1. put the jars/frameworks in a package, that you can extract on any  
plattform (zip/gzip/rar).
2. clear up the license to make WO either a free download or charge a  
fee per dev-seat.


A goodie would be to add Apache-adaptors compilable on Win/Linux.


The problem with supporting only Mac OS X remains a problem though.

Re: Best Way® to test for existence of a rela tionship

2008-04-07 Thread Alexander Spohr


Fetch only ManufacturedParts.

Don’t use the relationship to Parts (if that’s what you do) to get the  
NSArray.
Either create a relationship to ManufacturedParts or fetch them using  
a qualifier.


Iterating over a mixed NSArray wanting only one special class is bad  
design. Filter it before you use it for such a task.

Am 07.04.2008 um 15:12 schrieb David Avendasora:

Hi all,

This is more of a Java question than a WO-specific one

I have an Inheritance structure in my app:

Part (abstract Superclass)
RawMaterial (subclass of Part)
ManufacturedPart (subclass of Part)

I have an NSArray of Parts that could be, RawMaterial instances,   
ManufacturedPart instances, or most likely, a mixture of the two.


I want to iterate through the Array and get the contents of the  
Part.billsOfMaterial() (toMany) relationship. The problem is that  
while ManufacturedParts have this relationship, RawMaterials do not.


Right now, I'm using a try-catch block that catches the exception on  
RawMaterial.billsOfMaterial() and just ignores it.


I could also add a billsOfMaterial() method to the RawMaterial class  
that simply returns NSArray.emptyArray.


Is one way better than the other for any reason?

Thanks,

Dave

Wouldn’t it be enough to just flag the RawMaterial ones as such and  
just have one class for both?

Am 07.04.2008 um 18:02 schrieb David Avendasora:
You know, I was hoping to avoid the whole question if the domain was  
actually well-modeled or not, but with such dispersions cast on my  
flawless modeling skills, I must respond! :-P


I have 2 types of Parts. One purchased from an outside vendor  
(RawMaterial), and ones that are manufactured (ManufacturedPart).  A  
ManufacturedPart is made up of any number of component Parts. These  
component Parts can be _either_  a RawMaterial or another  
ManufacturedPart.


So I have modeled it like this:

ManufacturedPart - BillOfMaterial - BOMComponent - Part

To make things more complicated each given Manufactured Part can  
have one or more ways of making it and therefor have multiple  
BillsOfMaterial.


Hence, I have a branching, recursive relationship tree that can be  
any number of levels deep:


ManufacturedPart - BillOfMaterial - BOMComponent -  
ManufacturedPart - BillOfMaterial - BOMComponent -  
ManufacturedPart - Rinse, lather, repeat.


Or it can be very simple

ManufacturedPart - BillOfMaterial - BOMComponent - RawMaterial

What all this comes down to is that billsOfMaterial() does _not_  
belong on Part as it does not belong on RawMaterial because a  
RawMaterial is NOT manufactured by us so it will never have a  
BillOfMaterial.


But there are several places in my code that I want to recursively  
navigate this tree and I just don't see a right way to do that  
without some variation of instanceOf (in code or in a fetch), a case  
statement or adding the method to Part.


The simplicity of one simple method returning NSArray.emptyArray  
wins. Even though it sullies my object graph, it does so in a much  
less complicated, fragile way.

that the model / design is incomplete and leading David into doing  
Bad Things in code.


Otherwise, (a) the model is just wrong, or (b) David's processing

Hello

As I get rolling down the EO highway, I find myself wanting to put  
convenience functions in the model classes that are generated by the  
EOGenerator (yes, I'm using the generation gap classes for this).   
e.g. to more closely mimic indexing a two dimensional array like the  
old way I used to do things, I create the following to retrieve a  
Game object from in from a model class that contains a one to many  
relationship to Game objects:


  public Game game(int group, int gameIndex) {
	EOQualifier gameQual =  
Game.GROUP.eq(group).and(Game.GAMEINDEX.eq(gameIndex));

Game game = this.games(gameQual).objectAtIndex(0);
return game;
  }

Is this a good thing?  Just hoping to get some feedback before I go  
too far down this road.


If you only want to have only one Game at all, yes.
If you are going to call this in a loop, no and never!

Remember that every call of this method goes into the database. That  
will kill your app.
Better fetch all Games in memory and order them into an  
NSArray(NSAray()) and use that.
