Re: Running through Apache, and testing in VMWare/Windows
I test Windows on Parallels. One way is to install Bonjour for Windows on your Windows VM and then use http://andrewsmac.local/ (or whatever your bonjour name is). Another way is to just use the Mac's IP address in the URL. On Dec 7, 2010, at 4:52 PM, Andrew R.

Re: Running through Apache, and testing in VMWare/Windows
Yep, I think if you use a NAT network setup you can't connect from Windows to OS X by IP. I always setup my VMs to use a bridge (don't know the exact term in English, my copy of Fusion is running in French). What is the networking setup of your VMWare virtual machine?

Re: Running through Apache, and testing in VMWare/Windows
They also have a paid version. But personally, I trust more VMWare. Virtualization is their core business and so far Fusion have been rock solid for me (using it since mid 2008). hold on a second - on the bottom of that web page there is an oracle badge. let me guess: it's free to download and free to install, but drains a $1000 per second from your bank account when you're not looking ? :-) simon On 8 December 2010 00:25, Chuck Hill ch...@global-village.net wrote: Mostly unrelated, but I ran across this the other day: http://www.virtualbox.org/ Free(ish) and there is an OS X version.

Re: Running through Apache, and testing in VMWare/Windows
Yeah, I just changed that (It is called Bridge vs. NAT which is the default).

Re: Need help with a (non) deadlock Issue
you can't spot the deadlock here ... it means a previous thread left the osc locked and went away. because there's no thread BEYOND that lock, it means the thread is gone now and you'll have to try and track down the one the had a problem. I would look for possibly exceptions that were thrown in the logs that might have not had a finally?

WOBrowser selections missing
Having some WOBrowser weirdness, after upgrading from OS X 10.5 to 10.6 (Snow
Leopard) and from WebObjects 5.3.x to 5.4.1. This issue did not happen prior
to the upgrade. Problem is, the selected items from our WOBrowser are not
being passed correctly to our Java code.
So I tried running this in Eclipse debug. My WOBrowser has about 450 items in
it.
* If I selected the first item in the list, selectedClientList contains
the one item. Cool.
* But if I selected any other item besides the first,
selectedClientList is empty.
* And if I multi-select 3 or 4 items, sometimes selectedClientList is
empty, and other times it will have just the first item I selected.
Any thoughts on what could be causing this?
Here's our WOBrowser. selectedClientList is defined as public NSArray in the
accompanying java class.
Browser3: WOBrowser {
displayString = currentClient.displayName;
item = currentClient;
list = clientList;
multiple = true;
selections = selectedClientList;
style = width:270px;
value = currentClient.displayName;
}
Thanks!

Re: Need help with a (non) deadlock Issue
My guess is that you passed some EOs into your quartz scheduler that is running in a separate thread. That is a good way to shoot yourself in the foot. Just pass in identifiers to your thread and refetch them in the scope of the thread and clean up after your self inside the thread.

Re: Index problems
Hi Calven, What Chuck is saying is that while you are _expecting_ two inserts, that second insert is _not_ the one you think it is. EOF hasn't yet gotten around to that insert yet and because it is failing on the one with a PK of 56, you don't see it. As far as the insert with the PK of 56, he's saying that that insert really is probably supposed to be an update or a delete, but because EOF is in a confused state, you are getting a completely bogus SQL command that just happens to be an insert. Chucks point is that when this type of thing happens, it's because you are violating one or more EOF commandments (see: http://wiki.objectstyle.org/confluence/display/WO/EOF-Using+EOF-The+EOF+Commandments) somewhere in your code.

That is violating EOF commandments for sure. then how? (I've read the commandments and I don't see your comment above in there) Essentially this is what is done... EOClassDescription cd = EOClassDescription.classDescriptionForEntityName(entityName); EOEnterpriseObject eo = (EOEnterpriseObject)cd.createInstanceWithEditingContext(ec, null); Save some typing: MyClass myClass = (MyClass)EOUtilities.createAndInsertInstance(ec, entityName); Wonder templates make it even easier. ec.insertObject(eo); eo.takeValueForKey(noteDescription, notesdescription); That is OK, provided that noteDescription is a local ivar and not on an EO. Touching an attribute of an EO that has not been inserted (which is what I thought you were describing) is a Bad Thing (tm) to do. ... ec.saveChanges(); If that is exactly what you are doing, then ec is already trashed by the time you get here or is not locked. I would suspect the former. Tracking this problem down to the code causing it can be very hard as the cause maybe far away in code and appear totally innocent. Chuck that's when I do the saving/inserting into the database. but then the sequence numbers are incorrect for the second one. what is the other insert you are talking about?

Re: Need help with a (non) deadlock Issue
Hi Dov, Thanks for the input. I did find one quartz job that I'm passing EOs into. But inside the quartz job I create a new editing contenxt use editingContext.faultForGlobalID to bring those objects into the local editing context, and then I dispose that editingContext in a finally block. Is disposing editingContexts what you mean by cleaning up after myself, or is there more to it?

No, not directly. Fetching and saving cause OSC locks. Those should be released automatically. If you are using Wonder, it is possible that something you are using has a bug that is leaving a hanging lock. Is there a more recent version you could update to? Running out of memory can also sometimes cause this (and a lot of other unpredictable chaos). Check the log for heap and OutOfMemory. Otherwise, some code in your app or in some code you are using is locking the OSC and not unlocking it.
