Re: Does the ERXStaticResourceRequestHandler work with those compressed jarred resources?
The reason we don't do it ourself is that a lot of that stuff calls into erxfileutils and that uses path names. Fixing it would be a lot of work and make code more complicated without a lot of real gain (at least from when I last looked at it). So unless any of the committers actually need to use this themselves, I wouldn't hold my breath waiting for it.

Solaris SPARC WO Adaptor
Hi everyone, I'd need to setup a running WO environment for a client on a SPARC Solaris 10, with Apache 2.2. Would it happen someone has already a precompiled WO Adaptor for this platform please ?

Re: any there any other actions which could cause a timeout?
Hi Jake; If you don't have concurrent request processing turned on then if an instance (X) is already dealing with another request which takes more than a few seconds to return a response, the Apache adaptor seems to fail-over a new inbound request to another instance (Y) even though the new request is related to a session. As the second instance (Y) is oblivious to the session on the new request it gives you a session timeout response. This could be what is happening in your case. cheers. can someone tell me if there is anything else which can cause a timeout? we have set setSessionTimeOut to be an hour in Application class, but we are intermittently experiencing timeouts when the hour has not been reached. ___ Andrew Lindesay www.silvereye.co.nz ___ Do not post admin requests to the list.

(dead)locking of EC and OSC
Hi, We recently had some deadlock problems involving EC and OSC locking, and I would like to validate my thoughts with the list. As a very basic rule with everything multithreaded, whenever two threads want access to the same resources, they have to lock them in a predefined identical order. Otherwise you have that classic deadlock possibility, where T1 has A and wants B, and T2 has B and wants A. This, for EOF, means the following: Whenever you hold an OSC lock, you are NOT allowed to lock any EC anymore! Why not? Cause the normal order is the other way round. First you lock the EC, then, when doing something with it, you lock the OSC. For example, our specific deadlock occurred, cause we had a Thread1: - lock the OSC - in a loop, do some operations involving locking of lots of ECs (we have some stuff in there, which posts notifications to all ECs) - Unlock OSC Now, while T1 was busy in its loop, some T2 was fetching a single EO: - lock the EC - fetch EO causing OSC to lock - which waits for T2 to finish And, as soon as the T1 loop reaches the locked EC of T2 - Deadlock Now, the questions I have: - Is this analysis correct? - What do we do about it? If I understand all this correctly, my above rule means: _Whenever you have the need to explicitely lock an OSC, you can't do any operation, which would cause an formerly unlocked (by you) EC to be locked._ Which might be more than you think. IIRC, you are not allowed to make any changes to any EO. Because that causes EOObjectsChangedInStoreNotifications to be fired around to all ECs. Which in turn, causes all these ECs to be locked. Which violates the rule. Now, if you really need to do this (you NEED to lock an OSC, and you NEED to use ECs while having it locked), you could think, Oh it's OK, I just lock all of them first. But then again, in what order do you lock the ECs? Because if you do it in random order, you again have the possibility of deadlock. So, what is everybody doing? - I don't lock the OSC myself. Why would I want to? - I do, but I am VERY careful about what I do with it being locked. - I do, and so far I have been lucky. BTW, this deadlock we had occurred about once a week. As such, it was not really reproducible on a developer machine. We finally catched it, when we put that T2 thread in an endless loop, letting it refetch that same EO again and again. The Eclipse Console didn't like the logging output of that thread at all :) Greetings, Marc ___ Do not post admin requests to the list. They will be ignored.

Re: Does the ERXStaticResourceRequestHandler work with those compressed jarred resources?
Hm. Then again, IIRC we use strings for paths... so you probably *could* give these methods a jar:xxx string and handle that in the method. Not the cleanest way, but what the heck. I'm not sure if not using the default props is that good a thing. Sometimes these change or get added to and you would want to get the additions.

Dumb ERAttachmentFlexibleUpload question
I am trying to use ERAttachmentFlexible upload in our app. We have a
communication entity, which has up to 5 attachments of type ERAttachment.
(attachment1, attachment2 . . ., etc.) all are foreign keys to the
ERAttachment.
I am trying to use ERAttachmentFlexibleUpload inside a subcomponent which
itself is contained in an AjaxModalDialog. This seems to work for the first
attachment I upload, using relatively few bindings
ERAttachmentFlexibleUpload : ERAttachmentFlexibleUpload {
attachment = attachmentItem;
editingContext = communication.editingContext;
finishedFunction = new function() { attachmentUploadContainerUpdate() };
selectFileButtonClass = prettyButton;
selectFileLabel = Choose File;
}
I am not a javascript whiz to say the least, so I am having difficulty figuring
out what the javascript is doing and where it is (e.g.
attachmentUploadContainerUpdate())
Also, I don't know where the default css is.
The main problem is that when I delete an attachment (by setting it to null in
the communication's edit component), then I want to add another attachment, the
old filename appears, with a clear link below it. I have no idea why that is,
or where that is happening.
I assume there is someplace someone could point me to.
Thanks

Well that will update an ajax update container with the id

Also, I don't know where the default css is.
Because ERAttachmentFlexibleUpload is based on AjaxFlexibleFileUpload the

It is not clear what you are doing here. How and where are you deleting the
attachment again?
Have you looked at using ERAttachmentFlexibleEditor? It uploading adding
*and* removing/replacing attachments.
OK, that makes no sense... trying again: It supports uploading *and*
removing/replacing attachments.
I assume there is someplace someone could point me to.
Thanks
The bindings for the various FlexibleUpload (which I just realized compresses
to FU... oops) components are documented in their respective java docs.

Unfortunately, this didn't actually solve anything. Also, I don't know where the default css is.

I have no idea why that is, or where that is happening. It is not clear what you are doing here. How and where are you deleting the attachment again? Basically, I have an edit component which contains the AjaxModalDialog containing the subcomponent with the Flexible Uploader The edit component edits the communication in general, and as part of that, the user can attach up to 5 files. These appear in an inline worepetition with a close button. Clicking close tells the attachment represented by that index to be set to null. e.g. click the close button for attachment1 sends communcation.setAttachment1(null) There are also links at the end of the repetition to add more attachments. Clicking one opens the AjaxModalDialog containing the subcomponent with the ERAttachmentFlexibleUploader. The first time you click Add File the dialog appears with the choose file button reflected as a shrunken version of my standard prettyButton . . . presumably it's shrunken because of something in the CSS. Once you choose a file, it's uploaded and it appears with a red x close button. Presumably also in the CSS. (I originally didn't set the choose button class and got a blue choose button which apparently didn't have a grey background, so the corners are a little weird. Hence I tried to use our button class) After you upload a file, and click my Attach button (which simply sets the attachmentItem into the first available spot for the communication's attachments -- e.g. communication().setAttachment1(attachmentItem). This appears to work. The dialog goes away and the attachment appears. If you click our close button for it, it disappears. Then if you click attach files again, the old attachment's filename appears, with a Clear link under it. I'd rather have it just open an empty one uploader with a default button instead of a clear link. Sorry I wasn't clearer earlier, Dave A was harassing me to go to lunch. I can't disappoint Dave. Have you looked at using ERAttachmentFlexibleEditor? It uploading adding *and* removing/replacing attachments. I was originally looking at using the editor, but they actively didn't want to see the uploaded file (dunno why) so I went back to the Flexible Uploader.

I have a model where an entity A has a recursive relationship as parent
toParentOfTypeA() and children toChildrenOfTypeA(). Consider it as a tree
structured entity.
In the model have setup the entity to delete cascade.
In the entity I have overriden the method willDelete(). Now when I delete the
parent, it fires the willDelete() of it but does not fire willDelete() of it's
children. When I checked in the willDelete() I found the toChildren()
relationship is empty but the children are there and I access it in the
component when I generate tree. Below is the source code.
Follwing method is overridden inside entity A.
public void willDelete() {
ERXUtilities.deleteObjects(editingContext(), toChildrenOfTypeA());
}
// below code is somewhere else.
A a = // object retrieved from the db.
a.delete();
Any Idea? If needed, I can send the source code too.

Re: Dumb ERAttachmentFlexibleUpload question

Kinnie wrote: On Jul 23, 2010, at 1:19 PM, David LeBer wrote: Well that will update an ajax update container with the id 'attachmentUploadContainer' Well that clears that much up. Unfortunately, this didn't actually solve anything. Also, I don't know where the default css is. Because ERAttachmentFlexibleUpload is based on AjaxFlexibleFileUpload the default css is in the Ajax framework: default_ajaxupload.css Thanks. I didn't even think of that. I'll look there. The main problem is that when I delete an attachment (by setting it to null in the communication's edit component), then I want to add another attachment, the old filename appears, with a clear link below it. I have no idea why that is, or where that is happening. It is not clear what you are doing here. How and where are you deleting the attachment again? Basically, I have an edit component which contains the AjaxModalDialog containing the subcomponent with the Flexible Uploader The edit component edits the communication in general, and as part of that, the user can attach up to 5 files. These appear in an inline worepetition with a close button. Clicking close tells the attachment represented by that index to be set to null. e.g. click the close button for attachment1 sends communcation.setAttachment1(null) Are you ever actually deleting the Attachment? Wouldn't this leave one dangling? There are also links at the end of the repetition to add more attachments. Clicking one opens the AjaxModalDialog containing the subcomponent with the ERAttachmentFlexibleUploader. The first time you click Add File the dialog appears with the choose file button reflected as a shrunken version of my standard prettyButton . . . presumably it's shrunken because of something in the CSS. Once you choose a file, it's uploaded and it appears with a red x close button. Presumably also in the CSS. (I originally didn't set the choose button class and got a blue choose button which apparently didn't have a grey background, so the corners are a little weird. Hence I tried to use our button class) After you upload a file, and click my Attach button (which simply sets the attachmentItem into the first available spot for the communication's attachments -- e.g. communication().setAttachment1(attachmentItem). This appears to work. The dialog goes away and the attachment appears. If you click our close button for it, it disappears. Then if you click attach files again, the old attachment's filename appears, with a Clear link under it. I'd rather have it just open an empty one uploader with a default button instead of a clear link. Sorry I wasn't clearer earlier, Dave A was harassing me to go to lunch. I can't disappoint Dave. Hmm. The ERAttachmentFlexibleUpload/AjaxFlexibleFileUpload cache the filename as their default behaviour. My brain is farting right now and I cannot think of a simple way to get them to reset that value when the AMD opens. There is a binding that will bypass the showing of the uploaded file name and clear button: 'clearUploadProgressOnSuccess' - it defaults to false. However with this set, there will be no indication of what file you uploaded, the uploader will revert to a select button. You can look at ERAttachmentFlexibleEditor as an example of how to setup a view/upload/replace workflow with these components. You could possibly set that binding and have the success function of the uploader close the AjaxModalDialog. Have you looked at using ERAttachmentFlexibleEditor? It uploading adding *and* removing/replacing attachments. I was originally looking at using the editor, but they actively didn't want to see the uploaded file (dunno why) so I went back to the Flexible Uploader. I will look at the other things you mentioned, and hopefully that will explain things better for me ;david -- David LeBer Codeferous Software 'co-def-er-ous' adj.

My approach is somewhat different Break it down into steps: - is Apache running: curl http://host - is the WOAdaptor loaded: http://host/cgi-bin/WebObjects/WOAdaptorInfo - which wotaskd's is the WOAdaptor talking to - they are listed on the WOAdaptorInfo page - which application instances are controlled by those wotaskd's - also listed on the WOAdaptorInfo page - does the WOAdaptor think that your app instances are dead? - dead time listed on the WOAdaptorInfo page You get the idea where I'm going with this! ;-) I should point out that you might find the updated WOAdaptor in wonder useful here because it's ability to log messages has been fixed/expanded.
