Login oddness
Has anyone any thoughts on an issue I am experiencing. I have an application deployed on a Linux system which has been running fine for a long time. Just recently (I think it was after the 10.4 recent update but can't say it was that) I began finding that the app does not hold onto certain session related pages when using Firefox on mac and pc and also Safari on Mac. This is really odd as the server application has not been modified... Any thoughts on what possibilities it could be or how I could determine its cause...

conditional link
I want to have an WOimage that, when clicked, will offer the option of inserting an object (revealing a conditional input field). I'd like to offer this ability within the same page using a WOConditional; meaning when a user clicks on the button, it reveals a section where you can insert an object (string in this case). Since my conditional-based knowledge is a bit weak, I can do this by sending the user to another page, but I'd rather not. How can I keep them in the same page? Ideas?

I do this kind of thing all the time.
Usually an editFlag boolean on the page is all you really need. Bind
your WOConditional wrapping your form to that and add some management
actions:
protected boolean _editFlag;
public boolean editFlag() {
return _editFlag;
}
public void setEditFlag(boolean flag) {
_editFlag = flag;
}
public WOComponent editObject() {
setEditFlag(true);
return this.context().page();
}
public WOComponent saveChanges() {
// blah, blah
setEditFlag(false);
return this.context().page();
}
public WOComponent cancel() {
// blah, blah, ec.revert(), blah
setEditFlag(false);
return this.context().page();
}

Re: Unit testing
I (almost violently) oppose any code in a a WOComponent not directly and exclusively tied to making the UI function. I try to restrict them to binding variables, cover methods, and overrides for inherited methods. Everything else belongs someplace else, either in the EO or in a layer between the EO and UI. Doing this, the UI classes become very simple. So simple, in fact, that they could not possibly break. Therefore there is no need to write tests. Any potential bugs are best caught in functionality testing. Chuck On Nov 7, 2005, at 7:52 AM, Sam Barnum wrote: Slightly different topic, but how do you write tests at the component level?

Re: Unwanted Session Creation
I recall a discussion of this in the recent past (search the

getting created? Maybe that will remind me. Logging out a stack

public Session() {
super();

the context().request(), but when I do session(), it is creating a

Under what circumstances does a new session get created? I guess a
work around would be to restore the session myself using the
sessionID from the request, but I would really like to know why it
would be occurring.
Any information is greatly appreciated.

Re: SharedEditingContext Write Locks?
Hi Dov,
as David said, EOSEC requires special care. OTTOMH I'd say the
problem is caused by your use of objectsWithQualifierFormat. I
normally use
EOSharedEditingContext.defaultSharedEditingContext
().objectsByEntityName().valueForKey(NameOfMyEntity)
You could then qualify on the array in memory using e.g.
filteredArrayWithQualifierEvaluation from WOnder's ERXArrayUtilities.

We recently made some changes to try to fix this problem. We set
the sharededitingcontext = null anywhere we created a new editing

Re: SharedEditingContext Write Locks?
Title: Re: SharedEditingContext Write Locks?
Hmmm, I kind of suspected that was the case. The whole reason we were using SEC at all was to help performance under load. It doesnt make sense to have to re-retrieve a lot of the info that is read only for every session that connects up. We tried caching Eos which failed miserably and have resorted to storing their primary keys and fetching as needed. We do have a NSMutableDictionary that we use as an EO cache (primary key is the key). We get a localInstanceofObject before doing anything with it.

EOSEC is known to be hard to use. Its very likely that you will have EOF deadlocks, which is what you see below. AFAIK the only way to use it without deadlocks is:
load the desired eos at startup and make sure they will -nevernever- change no matter if you fault them into another ec, set sec from this ec to null and change the eo there. Do not change them -anywhere-.

Some bugs I'll be filing for the new Builder... 1) I was getting some weird behaviour yesterday where the interface was getting out of sync with itself. i.e., I'd control+click to add a new Key - and if I cancelled (to go look something up first) and then did it again, sometimes the next sheet wouldn't appear for ages. Thinking it wasn't going to happen, I'd try it again, but then I'd get the sheet opening up whilst the popup menu was open - and then the popup window wouldn't go away... endless cycle. Has anyone else seen this... I'll file a bug today sometime once I've played with it a bit more to see if I can narrow down the bug. 2) Also, sometimes I'd click on the right side of a WOString and hit CMD+1 and get No object selected whereas if I clicked on the left side the selection would be available as normal. So, there's definitely some promise in the new Builder... but there's a few interface glitches to work through. 3) Ctl+Click to add a new Key/Action in WebObjects Builder, get the sheet... switch back to Xcode, attempt to add a new File (File New...) Xcode will give you the spinning beach ball and fails to add the new file until you cancel the sheet in WebObjects Builder! This is not in accordance with expected sheet behaviour.

Re: SharedEditingContext Write Locks?
We took a closer look at our code and made some changes. We were using a method out of EOUtilities to get data instead of using objectsWithFetchSpecification. Hopefully that will clear up our issue. I will let everyone know if that works. A point of clarification: Based on one of the links that someone sent along, it seems like the SharedEditingContext should never be passed into a method to do a fetch unless objectsWithFetchSpecification is used. It seems that objectsWithFetchSpecification is used to load the SEC, I am not sure why I would use objectsByEntityName or objectsByEntityNameAndFetchSpecificationName. It seems that these methods could return a huge number of objects. Is the idea that you could filter the Shared objects in memory like you would in the DB?
