Yeah, and I just checked again and I already have code that

with:

But if you're right, and EOF already uses this in its qualifier then I  
probably don't need to be doing that.


But maybe the problem is that of null results for these related  
entities where the qualifier applies.



I can't see why this should not work, I'd file a bug.


ok.

See logs below. The FooBar restricting qualifier is not being applied  
properly it seems.

Anything more complex than that I would recommend single-table.

Vertical or horizontal?  With vertical this will still select on the

Backtracking and Safari

[Chuck Hill]

Hi,

Safari, at least as of version 3.1.1 (5525.20) does not seem to  
respect the headers that control local page caching.  The Safari FAQ  
claims to show how to do this:

http://developer.apple.com/internet/safari/faq.html#anchor5

Returning
last-modified = ("Wed, 04-Jun-2008 00:10:53 GMT");
cache-control = ("no-store, no-cache, must-revalidate, max-age=0, post- 
check=0, pre-check=0");

expires = ("Mon, 26 Jul 1997 05:00:00 GMT");
date = ("Wed, 04-Jun-2008 00:10:53 GMT");
pragma = ("no-cache");

still results in Safari using the local cache instead of making a trip  
back to the server.  The Web Inspector in Safari show that it is  
getting these headers, but it seems to ignore them. I have reported  
this to Apple.


Obviously, this has rather serious implications for those of use  
deploying dynamic web applications.  The back button is hard enough to  
deal with when the browser works correctly!


Any suggestions for work arounds gratefully attempted.

Chuck

Parameterized NSArray in 5.3.3

[Qi Yang]

Hi all,

I set up WO5.3.3 on OS X 10.4.11 with Eclipse and Wolips. I've read
about the trouble with NSArray cannot be parameterized error, seems that
WO5.3 doesn't support it and that I need to add ERExtension framework
from project wonder. 

In the project I'm working on I need to use 5.3 because of some
compatibility problems, and I added both JavaWOExtensions and
ERExtensions frameworks in the build path, but can't seem to get rid of
the NSArray can't be parameterized error.

Is there any special way I need to set it up to make this work?

Re: WebObjects + iPhone SDK

[David Avendasora]

There is _no_ WO development tools or project templates in WO 5.4/ 
Xcode 3. Installing the iPhone SDK would have updated you to that.


You can run Xcode 2.x and WO 5.3.3 (The last version of WO/Xcode to  
have the WO dev tools) in parallel on the same computer, but it  
requires downloading a new version of Xcode 2.x specifically designed  
to run in parallel with Xcode 3. There are also installers out there  
that will install WO 5.3.3


But since Apple-supplied tools are deprecated and Apple now recommends  
(and uses internally) Eclipse/WOLips for WO development, now's the  
time to transition! Do it and don't look back.

Wow, so Tuesday really is WebObjects day. There is only 3:30-4:30 left
to fill. I haven't seen feedback sessions posted, so the WO stuff may
be here and gone as soon as the beer runs out on Tuesday :)

Re: Capturing Monitor, WOTaskd and launch logs on Leopard

My Boy Scout Good Deed For the Day:

Re: Null property exceptions

[Johann Werner]

By looking at your Entity Modeler screenshot again your relationship  
from Entry to EntryScore should have "id" as source attribute and not  
your entryScoreID (finally you want your PK to be propagated).  
Changing this you should not have any warnings when deleting  
entryScoreID.

When I try to delete the foreign key, I get a big error message:




If the relationship is setup as a "propagate primary key", why  
should the relationship be referencing it?


Then, when I select Delete Anyway, it deletes both the foreign key

Hi all,


Sorry if this is an already answered question, but I just  
installed Leopard, to try to switch before WOWODC, and don't have  
the time to properly search...


My problem is that wotaskd is not running, after updating to  
10.5.2 and WO5.4. In fact there is *nothing* in the /System/ 
Library/StartupItems/ folder. Nothing at all. WTF???  
Interestingly, when I first did the Tig - Leop upgrade of the  
drive in question, the 5.3 wotaskd was running, my guess is that  
this was trashed by the OS/WO update.


Btw, I did see David LeBer's blog post about wrong permissions on  
"/Library/WebObjects/Configuration/" folder, changed those to give  
the app server write permissions, but that's not the cause of my  
problem.

What is the lowest version of Eclipse that can be used with WOLips

Unfortunately, nightly and stable both require 3.3.x.

Re: Null property exceptions

[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.

Well, uh, how do you have it set?  Do you have any foreign key

When I try to delete the foreign key, I get a big error message:

If the relationship is setup as a "propagate primary key", why should  
the relationship be referencing it?


Then, when I select Delete Anyway, it deletes both the foreign key AND  
the relationship.   Now what?

Re: Null property exceptions

[Jeff Schmitz]

Yes, I had wondered about that myself.  The foreign key is a product  
of the GUI as when you create a new relationship, there is no way  
(that  I could find) to specify initially that you want it to  
propagate the primary key, so its created initially whenever you  
create a new relationship.  Then, when you specify later to "propagate  
primary key" from the relationship editor, the foreign key remains, so  
I thought perhaps is kept there, but entryScoreID is always equated  
with its own ID in the implementation.  Should/could perhaps the GUI  
auto-delete the foreign key when "propagate primary key" is selected?   
Would at least help DB neophytes like myself.


Also, I really don't care to get back to Entry from EntryScore, and  
anyway, if an entry's key is being propagated to its related  
entryScore, shouldn't you be able to get back to the entry from the  
entryScore by just using entryScore's ID (since it's the associated  
entry's ID too)?


Anyway, I'll try removing the foreign key and see what happens.  I  
thought I had actually tried it before and got some other error, but  
I'll give it another shot.
And thanks for the GREAT discussion, I've already gotten answers to a  
lot of lingering questions I had in my head.

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.

Hi Jeff,

what is your entryScore relationship like? Do you have "owns  
destination" checked? If yes then by creating an Entry object  
EOF does create an EntryScore object for you automatically. So  
when you save changes that object is still in the editing  
context but no attributes have been set and thus throwing  
NullPropertyExceptions for every attribute that does not allow  
Null.

Re: Null property exceptions

[Alexander Spohr]

Jeff,

you don’t want to propagate anything here.
entryScoreID is not a primary-key but a foreign-key, so you can not  
propagate it.
Owns Destination is wrong as well. You designed your relationships  
backwards (read: wrong).
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

existing entryScore instead of creating a new one:


 EOQualifier poolQual = Pool.NAME.eq(name);
 pool = Pool.fetchRequiredPool(ec, poolQual);
 entry = Entry.createEntry(ec, "DEFAULT", "pw", true, false, new

 entry.entryScore().setNumWins(0);
 entry.entryScore().setPlace(0);
 entry.entryScore().setPoints(0);

but now I'm getting a different validation error.  There's

Here's the basic code:

pool = Pool.fetchRequiredPool(ec, poolQual);

I removed some flattened relationships and now works fine

My guess is that you are doing the insert twice in the same  
transaction.  The transaction is then rolled back and consequently you
can manually insert the same values with no violation of the  
uniqueness constraint.  Turn on EOAdaptorDebugEnabled and
watch the SQL that's generated to get a better idea of what's going  
on.

I checked and rechecked, the value for column ID is UNIQUE!!!
also typing the SQL directly into database works!

Any suggestion?!!

Fwd: Relationship across model boundaries failing

[Juergen Lorenz Simon]

Hi,

Interesting to see which turn the discussion took. I assume the answer  
to the problem is, that
in the current state it's not possible. I worked around the problem by  
now.


The problem arose from the need to maintain a couple of IDs in a  
central place (table) and
have several models use it. All I needed was relationships from the  
other models to the model
in question, via n:m tables, without back relationships. I'm still  
slightly puzzled that it won't work.


Thanks for the help, as always.

J.L.Simon

Re: Null property exceptions

[Johann Werner]

Why do you have the attribute "entryScoreID" in the Entry entity? If  
you make a to-one relationship Entry->EntryScore and propagate the PK  
you only need an FK attribute in EntryScore that gets set to the PK of  
Entry by EOF.
In your exception it is complaining about the entryScoreID from Entry  
_not_ from EntryScore.
