In ERXSqlHelper-->MySQLHelper-->handleDatabaseException it swallows
the jdbc exception whole and never reports it. The best you ever get
bubbled up to you in a completely non-descriptive custom validator
exception.
I have been meaning to log this as an issue for a long time, sorry for

I have used Henrique's code, largely unmodified, backed by a PostgreSQL DATE column type in a deployed application since then.

In that thread you'll find several other suggestions, some of which people are apparently using quite widely, and with success.

If you're using full-blown timestamps elsewhere in your app (or if you choose one of the alternative solutions to your 1-day resolution problem that involves timestamps), be mindful of the "feature" in the PostgreSQL JDBC driver described in this thread: http://lists.apple.com/archives/webobjects-dev/2010/Dec/msg00058.html and the workarounds listed here: http://wiki.objectstyle.org/confluence/display/WO/Project+WONDER-Frameworks-PostgresqlPlugin in the yellow warning box entitled "JDBC driver adjusts timestamps". -- Paul. http://logicsquad.net/ ___ Do not post admin requests to the list.

Handling GET Requests & Redirecting
Hi, I'm hoping someone can help me with this problem. Let's say I have a Person object. How would I go about handling a GET request (with query strings) to delete a Person, save the changes to the database, and then redirect to a URL (not a WOComponent). Oh, and I need to have a Session available as well. Initially I thought about doing this as a WOComponent and calling one of it's methods from the constructor, but then there is no clean way to redirect the response. The alternative seemed to be to use DirectActions. But using this method seems to mean I will have to write a direct action for each "action" (like delete/add/edit) that I would want to perform on a particular EO. It gets even hairier if I would like to re-use these actions in an API. This seems a bit kludgy and very not the webobjects way so I think I'm missing something. Can anyone offer any suggestions? NB: My Session on awake, looks for certain cookie values, verifies hashes and loads a user account EO as a means of implementing Sign In "Remember Me", then cookies are updated and added to the response in the Session sleep method. It's a lazy man's Serialized Session Store. Does this sound like an appropriate use of awake and sleep? I also mention it in case it will mess with any response changes suggested for the redirect action. Thanks. --- Kevin ___ Do not post admin requests to the list. They will be ignored.

It does in British Columbia. We also have N for the Newfie drivers (or is that

I don't think much more got done, though I have more internally. It is an
interest of mine, so I would be keen on being part of the discussion.

Check for a custom EC, custom DB context, or delegates for either of those as a
place to start. At what point are you NOT seeing it? Could it just be getting

Yes, about as well as your exception. :-P

Re: how to handle dates alone
I think if you look, you'll see there's just a consistent time set on each date in your database but either way, you'll still have to deal with a regular date object - there's no alternative that's all that much better - at least not that I've seen working. In the end, you'll always have to keep your storage format and interface logic in sync if midnight is to remain midnight. What's your trouble now? Is your app presenting dates an hour or two off from where they should be? You'll have to change your timezone, change the data in the database or change your application's (Java) notion of the timezone. But hey, if you come up with something else, let me know for sure! All Dates are BAD dates! On Jan 28, 2011, at 2:00 PM, Theodore Petrosky wrote: > You say 'these are Java'. yes, but how it relates to the backend.

Java ONLY has a point in time. ONLY. JodaTime extends Java with some more, uh, relaxed attitudes towards dates. As David alluded to, dates in Java are no ones' idea of fun.

I lean toward normalizing the dates and looking at them more at presentation - relative date formats are all the rage because it excuses timezone and other issues but you always have to have a static way to store them - use seconds from epoch, or modern timezones or whatever is most consistent for your needs but you gotta stick to that. In your case, sounds like you just want to set the "time" to always be 5:pm or midnight or something, and just ignore that during presentation and input. Anyway, moving to a new box and timezone or changes like that are always tough, I feel for ya! At least you've caught it now eh? good luck, and sorry dates still suck and stuff.

Re: how to handle dates alone
You say 'these are Java'. yes, but how it relates to the backend. I have invoice dates in my database. it is just a date. no time. how can I set up Entity Modeler to not use a Timestamp. I tried the Joda Time stuff but it seems that there were problems so it was pulled. So I need to rephrase. How can I have a date column in my database and have an object in Webobjects that is date only and not care about times and timezones? Am I clearer?

Re: how to handle dates alone
Dates don't actually exist. Only instantaneous points in time exist (well, give or take certain theories from theoretical physics). What we talk about as dates are highly subjective spans of time. Standard Java does not support such subjective concepts. You could "normalize" all dates to noon in GMT so that the times are equal (assuming you never go more than 11 time zones away). The only other solution that I am familiar with is Joda Time.

how to handle dates alone
so I was out the other night with the really h (sorry wrong forum) How are people handling dates with no timezone (and no time, just the date alone)? I really want to use the date column type and not care about the time nor zone but I haven't figured out a way. I just got bitten with a timezone problem when shifting my app to a different box.

Perhaps if you cast correctly? The issue is with your code, not AjaxTabbedPanel.

AjaxTabbedPanel - exception while handling request
Hi,
I am trying to implement Project Wonder's AjaxTabbedPanel and
AjaxTabbedPanelTab in my application by following the Wonder Ajax
Examples from the link http://webobjects.mdimension.com/cgi-bin/WebObjects/AjaxExample.woa/1
. But after added these AjaxTabbedPanel and AjaxTabbedPanelTab in
my component's html and wod files then my page is not loading, getting
the following exception:
23848 [WorkerThread15] WARN NSLog -

Any help would be appreciated.
Also adding my Session class invokeAction method code:
public WOActionResults invokeAction(WORequest aRequest, WOContext
aContext) {
WOElement element =
(WOElement)requestLookup.objectForKey(aRequest.uri());
if ( element == null ) {
WOActionResults res = super.invokeAction(aRequest,
aContext);
try{
element = ((WOComponent)res).template();
}catch(Exception e){

return ((WOResponse)res);// Exception occurring
at this line-151.
}
if (res!=null && element != null && !
isReportMillComponent(element)) {
requestLookup.setObjectForKey(element,
aRequest.uri());
}
return res;
}
else if ( element instanceof WOComponent ){
((WOComponent)element).ensureAwakeInContext(aContext);
return (WOComponent)element;

return null;
}

WOWODC 2011: registration and lodging details
Good morning everyone, Everything's is up and running for registration and lodging for WOWODC 2011! Early bird pricing is $465 for an individual ticket, that offer ends on May 16. Regular pricing is $575 from May 17 to June 22. As the same as previous WOWODCs, you get an additional discount for groups. We also have a discount ($40) for people who stay at the hotel. If you are a member of the Community Membership program, you also get a $115 discount, but you cannot combine it with the "stay at the hotel" discount. About the hotel, fees start at $129 + taxes for a regular room. Don't forget that WOWODC is held on the last week-end of the Montreal International Jazz Festival, so hotels can fill up fast, and become pricy (for the WOWODC week-end, regular pricing at the Gouverneur is $179 instead of $129 for our group). It's probably best if you can book your room before May. Check out wowodc.com for all the details about registration, lodging and tips!

WebEx channel for the community
Hi everyone, We now have a WebEx channel for the community. That channel is a complement to WOWODC and will be use for: • presentations in other languages than English; • follow-up on WOWODC sessions; • shorter presentations (< 45 minutes); • case studies. One idea that we have is to do a monthly "Get To Know a Wonder component" where someone would show to use some specific component or other part of Project Wonder. The channel allows a limited number of connections, so members of the Community Membership program have access priority to the channel. But we can record the presentation and the presenter can decide if the recording can be made available to everyone. If you want to give a presentation on this channel, contact me directly or i...@wocommunity.org. -- Pascal Robert prob...@macti.ca AIM/iChat : MacTICanada LinkedIn : http://www.linkedin.com/in/macti Twitter : pascal_robert ___ Do not post admin requests to the list.
