[OT] The omnigroup does not like me anymore
Sorry for the OT posting. I am subscribed to various WO/EOF/Apple related mailing list from the omni group. For the last couple of days I have not received one mail from them. What I have done so far: Used the web interface to the listmanager to try and check my subscription. However as I could not remember my password I opted for them to mail it to me. While waiting for that mail my memory came back and I could log in. All my subscriptions are enabled and all look fine. Only after some hours I realised that the password reminder had not yet come. This made me really suspicious. So I put my mail server (Mac OS X Tiger with postfix) into postfix debug level log and waited what was going to show in the logs. Well, everything but nothing from the omni group listserver, Last desperate test this morning: while running tail -f /var/log/mail.log (still debug level) I again requested a password reminder. The web page tells me that the mail had been sent, but my log shows nothing. However all the spam as well as any other mail e.g. from lists.apple.com and everything else comes in nicely and shows in the log. Just nothing from the omni group (not even a connect attempt and a reject). I have sent a mail to the listmanager but have yet to receive an answer (and yes, I gave them an alternate reply to in case their mail server really hates me) So is anyone aware of any problem? Thanks a alot and again sorry for the OT ---markus--- ___ Do not post admin requests to the list. They will be ignored.

WebPdfReports and Header
Hallo, is there someone around who has solved this problem: - I use WebPdfReports - I need to have it use the right header for Download of the generated pdf-Files for InternetExplorer 6.x, which throws an exception with the default implementation (under ssl, but I suspect the ssl does not make the difference). So I would like to pass my headers via appendToResponse. If I put it into the page I generate the pdf from under append to response and a var, which is set to true while the pdf generation takes place, it seems the header are not set or overwritten. If I try to use pdfPage.appendToResonse I end up with no instance available in place of the pdf. Can someone please advice? Thanks, Ute ___ Do not post admin requests to the list.

Client side validateForDelete() workaround
Hi all,
Some time ago I noticed that validaetForDelete() does not work
properly in client side EOCustomObject's implementation. It turns out
that the bug is in EOClassDescription.validateObjectForDelete
(EOEnterpriseObject), which does not properly check relationships
against deletion rules. The deletion rules however are present in the
class description, so I overrode validateForDelete() in my common EO
superclass. I have reported this bug quite some time ago, but it
still is not fixed. Anyway, for anyone who might fight the same
problem, the implementation is below. My first tests show that this
works OK. Please let me know however if you find any mistakes in it.
Cheers,
Flor
/**
* Overriden because the client side implementation of
* ttEOClassDescription.validateObjectForDelete(EOEnterpriseObject)
/tt does not
* perform proper checking against deletion rules.p
*
* This implementation first invoked the superclass' implementation
(which might throw),
* and thereafter checks manually for relationship deletion rules and
this object's
* relationship, to verify that the object indeed is valid for
deletion.
