merging changes upon a save: what are “locally uncommitted changes”, too many snapshots?

[OCsite via Webobjects-dev]

Hi there,

is the process of merging changes upon a save into other ECs, and all the kinds 
of snapshots available, documented somewhere in detail?

My old EOEditingContextConcepts says just this:

... However, locally uncommitted changes to objects in the EOEditingContext are 
by default reapplied to the objects, in effect preserving the uncommitted 
changes in the object graph. After the update, the uncommitted changes remain 
uncommitted, but the committed snapshots have been updated to reflect the 
values in the EOObjectStore.

and I can't see what does it actually mean “locally uncommitted changes” here. 
Most probably a difference from some snapshot, but I admit I am sort of lost in 
the things.

So far I lived in impression that (if we ignore undo) there's only one kind of 
snapshots: OSC-level shared snapshots of what-was-just-saved-into-DB.

I've tried to research the thing a bit and there seem to be at the very least 
the following snapshots:

(i) EC.committedSnapshotForObject
(ii) EC.currentEventSnapshotForObject
(iii) EODatabaseContext.snapshotForGlobalID
(iv) EODatabaseContext.localSnapshotForGlobalID

I regret to say the standard documentation does not help much. I did some 
testing and it looks like

- (iii) is the one snapshot I knew: whenever save finishes, it always contains 
the newly saved values
- (i) and (ii) — which for me always contain same data, that's weird! — seem to 
contain an EC-level snapshot stored at its (first) willChange. Also it looks 
like those “locally uncommitted changes” are based on (one of) these. So far 
though I haven't found a case when (i) would differ from (ii)... although, 
based on the name, I would actually presume (i) should be the same as (iii). It 
very definitely is not.
- (iv) I don't understand at all :(

Are those things somewhere documented in detail?

Thanks and all the best,
OC

Changes synchronized via jGroups won't always propagate on remote machines

[René Bock]

Hi!

We are experiencing issues with the RemoteSynchronizer (on jGroups), if we use 
more than one er.extensions.ERXObjectStoreCoordinatorPool.maxCoordinators (like 
20). The synchronization between instances is working, changes are distributed 
and fetched from the database, but they don't "push through" - if we read the 
EO-Entity that should contain those changes, we're getting the same data as if 
nothing was updated.

It seems to work most of the time if we create a new session: if we hit a new 
WorkerThread we get the changes, if not we'll end up with the old data.

We tested it with two vastly different projects (also vastly different in age 
of the product) and both suffer from the issue mentioned above.

We looked into the mechanics and wondered, why the following three lines are 
present in processing of local changes 
(ERXObjectStoreCoordinatorSynchronizer.ProcessChangesQueue.UpdateSnapshotProcessor.processSnapshots()),
 but not in the remote-version of this 
(ERXObjectStoreCoordinatorSynchronizer.ProcessChangesQueue.UpdateCacheChangeProcessor.processCacheChange()):



NSMutableDictionary userInfo = new NSMutableDictionary(gids, 
EODatabaseContext.UpdatedKey);
userInfo.setObjectForKey(Boolean.TRUE, 
ERXObjectStoreCoordinatorSynchronizer.SYNCHRONIZER_KEY);
NSNotificationCenter.defaultCenter().postNotification(EODatabaseContext.ObjectsChangedInStoreNotification,
 dbc, userInfo);


We added those lines on the RemoteChanges-side and our issue was gone.



Our question is, if this could be a bug, or "if we are doing something wrong" 
because no one ever faced those issues... :)

What would be the consequences if we add those three lines to the 
UpdateCacheChangeProcessor (or wherever it'd be needed to process all kinds of 
changes)?

Another question would be: Why is it working with only one 
ObjectStoreCoordinator?


PS: Since we're using a WebSphere environment we can't use the usual "20 
instances, one ObjectStore"-approach, we need to use many concurrent threads in 
a single process. This issue is also occurring outside of WebSphere though (if 
more than one ObjectStoreCoordinator is used with remote instances).


PPS: see also https://github.com/wocommunity/wonder/issues/866


Thanks a lot for your time!
Best regards

René Bock

Thanks. I’ve just made a pull request for these:

https://github.com/wocommunity/wonder/pull/806

As I note in that ticket, I don’t use this package, but I assume you have the 
second patch in use and that it does what it seems to do. If you have time, 
could you add some reassuring comments to the ticket? Then we’ll merge it.

Re: ERGroupware changes

[Fabian Peters]

Hi Pascal,

 This is the first time I heard from someone who is using ERGroupware :-)

Thanks a lot for publishing it, Pascal!

 Yeah, the cdav-connector is not complete, I will have to work on this. About 
 the More than one UID found in calendar, that's because you can only add 
 one vCalendar object by CalDAV. iCal is splitting the file in chunks and send 
 each vCalendar object separately. So instead of adding the event to a 
 calendar object in a loop, you should ship the event in the loop.

Right, that was it. And it makes sense now, after reading up on the WebDAV 
resource scheme.

I'm planning to make course data available via CalDAV (events) and CardDAV 
(participants). Ultimately I'd like to allow organisers/employees to access all 
data, instructors to access event and participant data of their courses only 
and participants to access event data of their courses only. I'm still 
wondering how to best organise the calendar data to make it easy enough to use 
for non-technical users and avoid too much duplication. I remember iOS devices 
having no support for delegated calendars, is that still true?

Thanks, Fabian

 Hi Pascal,
 
 I've just started to look into ERGroupware and wanted to make sure I'm using 
 the cdav-connector version, but I cannot seem to find any references to e.g. 
 zswi.objects in the code of the cdav-connector branch? It looks like master 
 and cdav-connector are identical.
 
 I bumped into an issue with the old (?) ical4j connector: Calendars.getUid 
 throws a ConstraintViolationException More than one UID found in calendar 
 when I add more than one event to a calendar and then try to add it to an 
 existing CalDAVCollection on a DAViCal server:
 
for (CourseEvent anEvent : aCourse.events()) {
ERGWEvent event = new ERGWEvent(cal);
event.setStartTime(anEvent.startDateTime());
event.setEndTime(anEvent.endDateTime());
…
}
…
 
CalDAVCollection defaultCollection = store.getCollections()
   .objectAtIndex(0);
defaultCollection.addCalendarObject(cal);
 
 Generating the ics file via ERGWPublishCalendarPage works fine and iCal 
 accepts it and pushes it to that same calendar on DAViCal w/o issues.

Do you want to let organizers edit the events in a « regular » CalDAV client or 
only from a Web interface?

An option would be to use the sharing option (not all CalDAV servers support 
this), with an account that have every calendars and share the calendars to 
groups.

iOS supports delegated calendars, but you have to enter the URL for the 
delegated into the device. You can’t add them with Profile Manager, but adding 
them manually works. This is what we did at work for the calendars of our sales 
team.

No, the CalDAV data will be read-only. Keeping the data on the CalDAV server up 
to date will be enough of a hassle, I guess.

 this), with an account that have every calendars and share the calendars to

Yes, that sounds like a good approach. Storing all calendars (one per course?) 
under the organisers' account and then sharing them to others.

 iOS supports delegated calendars, but you have to enter the URL for the 
 delegated into the device. You can’t add them with Profile Manager, but 
 adding them manually works. This is what we did at work for the calendars of

Right, now I remember having done something like this. Definitely not what I 
want to explain to non-technical, paying customers. ;-)

Multi Application Instance and propagation of EO changes

[Gino Pacitti]

Hi list
Im working on an App that requires an initial cache of read only EOs which will 
drive searches and result in paginated pages for display across the app 
instances.

But I also need to provide some administration of the database rows and for 
those changes to be propagated across the apps so that they are available to 
the EditingContexts/EOs so that the all post searches draw from updated objects.

Is there a Framework or strategy that can help with that?

Endless logs WARN NSLog - ** DirectToWeb could not find user.d2wmodel file. One will be created if you try to save changes.

[Christoph Wick]

Hi List,

I get endless logs of 

WARN  NSLog  - ** DirectToWeb could not find user.d2wmodel file.  One will be 
created if you try to save changes.

in Eclipse. I don't use DirectToWeb in this project. 

Does anyone know how to stop that?

Thx for any hint,

Re: Eclipse not seeing file changes.

Hi Tim,

Another problem with Mavericks - my mail (I use Gmail for small business) is

Anyway, I tried GOLips for the first time but I don’t think it completed the 
installation.  From the log:

You should be good to go. Eclipse is installed in '/Applications/eclipse'.

I don’t see the WOLips perspectives in Eclipse when I launch it.

Is that the right version?

ERGroupware changes

[Pascal Robert]

Hi,

At WOWODC, I said that I wanted to use another library for CalDAV and use it 
into ERGroupware. Well, I found that other library, in fact I wrote 75% of the 
code in that library.

  https://github.com/Kerio/cdav-connector

If you wish to try ERGroupware with that library, get the source of ERGroupware:

  https://github.com/pascalrobert/ERGroupware

And switch to the cdav-connector branch. Please note that if you have used 
ERGroupware in the past, the constructors have changed. That's probably the 
only change you will have to do in your code.

Changes to PostgreSQL unique constraint handling in ERXSQLHelper

[Paul Hoadley]

Hi Ramsey,

I used to handle unique constraint violations via a custom editing context 
delegate in editingContextDidFailSaveChanges().  This worked fine, but since 
upgrading to a more recent Wonder, this no longer works (that method is never 
called on the delegate), and now I get a stack trace containing an 
ERXValidationException.  I assume this is related to your commit here:

---
commit a3d8ae17480f04ff5b517c82fc3c864975c3af66
Author: nullterminated ramseygur...@gmail.com
Date:   Thu Jun 7 21:33:44 2012 -0700

Add unique constraint handling to ERXSQLHelper for postgresql.
---

(Until recently, the application in question was using Wonder dated prior to 7 
June, so the timing fits, at least.)  Could you explain how this new approach 
is supposed to work?  I'm sure it's better than what I was doing, but at the 
moment it breaks my delegate approach, and it's not clear whether I need to 
change every application that depended on that, or whether there's another 
centralised approach I could use.

Re: WOJenkins Changes Causes Jobs to FAIL

[Pascal Robert]

What about the job to install WO and Wonder? I guess the properties file name 
changed from hudson.build.properties to jenkins.build.properties ?

 Hey all,
 
 I've made a bunch of changes to WOJenkins, which I have rolled out to both my 
 own github repository () and the WOCommunity clone.
 
 The problem is that my changes have BROKEN existing jobs!
 
 The fixes are easy, though. You just need to make two changes to your 
 Jenkin's job configurations:
 
 1) Change the Execute Shell build step from:
   
 ${WORKSPACE}/WOJenkins/Build/WonderProjects/WorkspaceSetupScripts/SVNProject/GitWonder/setupWonderProjectWorkspace.sh
 to:
   
 ${WORKSPACE}/WOJenkins/Build/WonderProjects/WorkspaceSetupScripts/setupWonderProjectWorkspace.sh
 
 2) In the Invoke Ant Targets, change the -propertyfile argument from 
   -propertyfile ${WORKSPACE}/Root/build.properties 
 to 
   -propertyfile ${WORKSPACE}/Root/jenkins.build.properties
 
 That should get any of your projects building again!
 
 (you really should clone my (or WOCommunity's) repository and then target 
 your clone instead of using them directly, anyway…)
 
 However, I'll try to not make changes that will break builds without some 
 notice in the future!
 
 Sorry about that!
 
 Dave

KMAjax or Ajax?

If you are using KMAjax I could send you a more recent version (it's just my 
MooTools version of Ajax Frameworks).  It's probably (definitely) not as well 
supported as the regular Ajax framework.  You also can't mix and match Ajax and 
KMAjax components on the same page as I used the same variable names for the 
JavaScript objects  i.e. if you have a KMAjaxUpdateContainer you need to use 
KMAjaxSubmitButton.

aloha,

Re: Problems, Changes, and RIA

[Emmanuel Tote Dominguez Torres]

I would love to have the most recent version, I know it's pretty similar to
the Ajax framework but I prefer the KMAjax version, and noI was not mixing
them, After i had problems with KMAjax  i searched the mailing list for
questions about it, and as I did not find questions, I decided to migrate
to Ajax framework.

but I haven't get the same results as i got with your framework.

would you please send me the most recent version?or github repos? or svn
repos? to update from

Thanks a lot by the way. every time i get an answer on a question i feel
more like a part of the community although i have a long way to go to be a
good wo programmer.

also, is there any live site on the web that I can check on to take ideas
about what the framework can do in good hands?
dont matter i cant  see the code i just want to see a site made with
webobjects and kmajax.

Changes to BackgroundTasks and ERJasperReportsExample

[Pascal Robert]

I did a couple of small changes to BackgroundTasks and ERJasperReportsExample 
in Wonder.

First, they both use H2 as the default instead of MySQL, so hopefully the 
examples will run out of the box without any properties change. 

I also added a background task in a REST context example in BackgroundTasks. 
To start the app, you do a POST, like this:

$ curl -v -X POST 
http://192.168.0.106:65473/cgi-bin/WebObjects/BackgroundTasks.woa/ra/taskInfos.json

In the reply, you will a 202 code instead of 201 or 200, 202 = Accepted, 
meaning that the job was accepted. The response, you will also get this header:

HTTP/1.0 202 Apple WebObjects
content-location: 
http://mbp-pascal-robert-4.local:65473/cgi-bin/WebObjects/BackgroundTasks.woa/ra/taskInfos/17.json

So you can query that URL to find out details about the status of the task:

$ curl -v -X GET 
http://192.168.0.106:65473/cgi-bin/WebObjects/BackgroundTasks.woa/ra/taskInfos/17.json

When the job is still running, you will get a 200 code. But when the job is 
done, that URL will return a 303 code instead of 200, and again, with a header 
with a link to the details:

HTTP/1.0 303 Apple WebObjects
content-location: 
http://mbp-pascal-robert-4.local:65473/cgi-bin/WebObjects/BackgroundTasks.woa/ra/taskInfos/17/results.json

Just query that new URL to get everything.

Re: Changes to podcasts

[Pascal Robert]

It's mostly done, the ones that are not, it's because they have audio issues 
that came out in the re-encoding. I would say 90% of the podcasts had a diet 
and lost at least 50% of their size.

 Grat news,
 
 Thanks for the effort.

root directory of workspace changes

[Cheong Hee (Gmail)]

Hi all

I have relocated the root directory of workspace in Eclipse/WOLips.  Now the 
new launch of WOLips could not locate .project.  Is there any file or setting 
i could look at?  

Cheers

AjaxTabbedPanel - Implementation changes

[Raghavender]

Hi Chuck,

As explained in the email below, I have implemented AjaxTabbedPanel  
and AjaxTabbedPanelTab 's, in each Tab I am loading a component page  
and from that page I am navigating to the next page using  
AjaxSubmitButton action.  From the first page I am able to  
successfully navigate to the second page, and when I tried to navigate  
from the second page to third page using AjaxSubmitButton action but  
it is invoking the first page's AjaxSubmitButton action method.  The  
second page AjaxSubmitButton action method is not being called, and  
not able to navigate to the third page.  Please suggest how to handle  
multiple ajax submit actions in the same AjaxTabbedPanelTab page  
navigations.


Only the main page that has AjaxTabbedPanel and AjaxTabbedPanelTab 's  
have WOForm with multipleSubmit = true.  The component pages loaded in  
the Tab and navigated does not have any form in those pages.


Regards,
Raghu.

be keep navigating in the same AjaxTabbedPanelTab.  For example a  
Admin User selects a Test Results tab, and in that Tab the  
District selection page is displayed, after the district is  
selected then user clicks on next button to move to School  
selection page then move to next page for Students selection and  
finally generates a report.
All these component pages are extended ERXComponent and now in  
order to achieve complete Ajax based application and keep tracking  
of data while navigating from one page to another in the same  
AjaxTabbedPanelTab, what changes have to be made, please suggest.


My best suggestion is to come up with a better UI!.  What  you want  
to do might just work if you manipulate the selected bindings in  
code.

Re: AjaxTabbedPanel - Implementation changes

[Chuck Hill]

What you are doing is not something that I have used the AjaxTabbedPanel for, 
nor something I expected it to be used for.  I suspect the problem is in your 
code, but if you do find a bug in the AjaxTabbedPanel source, patches are 
welcome.

Re: Changes in Component HTML Not Immediately Showing Up

Hi again,

Just getting back to this issue now, and still no luck.  I've tried
bundle-less builds, selecting PB.project building, and deleting and

that next.  Any other ideas?

Thanks again for the help.

Re: Changes in Component HTML Not Immediately Showing Up

I would install jadclipse or jd (java decompiler) for eclipse and debug
these methods in WOApplication:

_rapidTurnaroundActiveForAnyProject
_initializeRapidTurnaroundMode

If rapidTurnaround is not active then you can try to find out why.

Try turning on the PB.project building in the WOLips prefs.  I think this
file is necessary for WO to enable rapid turnaround.

Changes in Component HTML Not Immediately Showing Up

[Joe Kramer]

Hi all,

I have a project that is no longer immediately showing changes that I make
to the component html file while the app is running (from debugger).  I used
to be able to make a change, save, build, and then refresh the page and see
the changes.  Something changed somewhere and now this is no longer the
case.  What do I need to do to get this working again?

Thanks,

Joe

Re: Changes in Component HTML Not Immediately Showing Up

[Joe Kramer]

Thanks again for the suggestions.  Still no luck.  I have Build
Automatically checked in the offending project, but I also have other
projects where I do manual builds and changes automatically show up.  I also
unchecked Generate Bundle to no avail.  This is more of an annoyance than
anything else, though it has cut my productivity significantly (mostly
because I have been trying to fix this :-) ).  Any other ideas?

Thanks again,

This also works sometimes. Delete the project from workplace and reimport. If 
your other projects are working, this will also work.

Good luck!

Re: Changes in Component HTML Not Immediately Showing Up

[Tim Worman]

After unchecking Generate Bundle is there still a Build folder in your 
project? If so, you should be able to delete it. My concern is that something 
in your build folder is borked - which can require a shaman to fix. Running 
without that is better.

After that I'd also do a Clean and Refresh (on the entire project). Good luck.

Hudson Build Script changes

[David Avendasora]

Hi all,

I've been busy today updating the shell scripts that are in the WOCommunity 
subversion repository so that they can maintain and use wonder builds that may 
not always be from trunk.

*** These changes will break any Hudson jobs that you may have setup that 
depend upon these scripts! ***

There are a couple things you can do to fix any jobs that are having problems:

• In the job configuration, add @122 to the end of the SCRIPT_REPOSITORY 
parameter. It would now be: 
https://services.wocommunity.org/wowodc/hudsonbuildfi...@122

OR - That's an or people

• For any of your own frameworks or applications, modify all of your jobs to 
include a WONDER_BRANCH parameter. It should look something like this:
inline: PastedGraphic-2.png
The build scripts will automatically pick up this new value and use it. Without 
this parameter, the build will fail.

• For any jobs you have that build Wonder, add the same Parameter, and change 
the Repository URL for Wonder to: 
${APPLICATION_REPOSITORY}/${BRANCHES_TAGS_TRUNK}${APPLICATION_BRANCH_TAG}/${APPLICATION_NAME}/${APPLICATION_REVISION}

The build scripts will automatically pick up this new value and use it. Without 
this parameter, the build will fail.

PRO TIP: You really should keep a copy of the build scripts that you use with 
each branch of your own projects so you will always have the scripts that built 
that particular release of your application.

Simple code changes require a restart of the app

[Ricardo J. Parada]

I just noticed that simple code changes require a restart of the app.

Does anybody have this problem? What should I check?

I'm using Eclipse 3.6.0 / WOLips 3.6.6142 / WO 5.4.3 / Wonder Revision 11424 
from https://wonder.svn.sourceforge.net/svnroot/wonder/trunk/Wonder

Thanks,
Ricardo

Re: Simple code changes require a restart of the app

[Farrukh Ijaz]

Check in the Eclipse that Build Automatically is selected.

Restart is normally required if you add new method, field, or change in 
property. Change in HTML is should work without restart. 

Use JRebel. Even with JRebel if you change the signature of existing method or 
class will require application restart.

Thanks.  That was it.  At some point I turned off Build Automatically and 
forgot to turn it back on.

Re: Simple code changes require a restart of the app

The memory problems happened for a week or two for me too. It is now working 
great. You might want to try it again. Any code change that normally requires a 
restart will no longer do so. There are a few exceptions, but it will tell you 
when it can't do it.

Re: Simple code changes require a restart of the app

[David Avendasora]

Memory problems?!

What are your launch arguments? I had to make some changes since with JRebel 
you're keeping a lot more in memory, but once I modified my launch arguments I 
haven't had a problem. Here's mine:

${jrebel_args} -XX:MaxPermSize=256m
-Xms512m
-Xmx1024m
-Drebel.log4j-plugin=true
-Drebel.webobjects_plugin=true
-Dwojrebel.noexclude

The last one is because I tend to poke around in the Wonder source.

Re: Simple code changes require a restart of the app

[Ricardo J. Parada]

I think it was the -XX:MaxPermSize which I had to set to something really big 
(like 2GB) or so.
But I may try it again to see if it got better.

Thanks for the info.

Changes in latest Wonder

[Frank Stock]

Hi,


I get a wrong date with the latest version of Wonder, getting data from my 
database (FB). (1 day earlier). I did my update on 09/23/10.

I have restored with  time machine  Wonder frameworks in /Library/frameworks 
from 08/17/10 and it works fine again.

What can be the source of that?

Re: Changes in latest Wonder

[Chuck Hill]

You will have to read over the commit messages, or find the classes that might 
affect this and do an svn log on them.

I don't recall any changes that would affect this and I am using FB and a very 
recent Wonder.

Are you building from source or downloading the binaries?  If so, which 
binaries?

Chuck

ERModernLook changes

[David LeBer]

Just a heads up folks.

Given that the Wonder_5_0_0_WebObjects_5_4_Branch was referred to as 
'experimental' at one point I've taken that as permission to do drastic things 
:-)

Well, not really drastic, maybe just a little drastic.

I pulled all of the non d2w components out of ERModernDirectToWeb (where they 
didn't really belong) and renamed and stuffed them into the fetchingly 
monikered ERCoolComponents framework. This means that the ERModern* frameworks 
and any apps built with them now have a dependency to ERCoolComponents.  I've 
done my best to hunt down and update all references to the old component names 
in the existing components and rules, but...

Please test your projects against the new branch when you get a chance and let 
me know if anything breaks horribly for you.

On the upside, there are a bunch of components in ERCoolComponents that aren't 
hidden away in ERModernDirectToWeb any longer.

D2W - execute custom code on save changes

[Tim Worman]

I'm using ERModernDirectToWeb to re-implement some admin parts of my existing 
application. One of the criteria I have is that under certain circumstances I 
need to log saved changes for audit reasons. I don't have to do it all the time 
so I need to interrupt in there with some branching logic.

The objects in question will be EO's so I thought about having the EO's 
themselves track the changes. The problem with that is that I really only want 
this auditing happening when accessing these EO's from the D2W admin interface. 
There are other processes that make changes to these EO's where I do not want 
the auditing.

Does anyone have some suggestions or pointers about where I can look to 
implement something like this?

Re: D2W - execute custom code on save changes

[Kieran Kelleher]

One suggestion:

Have a boolean attribute on user entity doesRequireAuditTrail and turn it 
on/off for users that require auditing. Put your current user EOGlobalID in 
ERXThreadStorage (do that in Session awake) and check the user's setting in EO 
state transition methods will* or did* and log as needed.

Re: D2W - execute custom code on save changes

[Ramsey Gurley]

ERCoreBusinessLogic has audit trails. You can subclass  
ERCAuditTrailHandler to customize it.  You specify the subclass with a  
property:


er.corebusinesslogic.ERCAuditTrailClassName=your.app.AuditTrailHandler

It's very nice. Auditing happens automatically whenever save changes  
is called via the magic of the NSNotificationCenter. I would go with  
this route personally.


If you want to inject custom logic into your submit method, you can  
hide the page buttons and supply your own buttons using a  
ERDBranchDelegate on your nextPageDelegate.  Doing that should display  
your custom buttons via the ERDActionBar.  Either that, or you can  
inject a custom Confirm page using the inspectConfirmConfigurationName  
rhs key.  Then I think you can supply the logic in a confirm delegate.

Re: D2W - execute custom code on save changes

[Tim Worman]

Thanks Kieran. I'm gonna have to look into ERXThreadStorage. I know vaguely 
what it is for but haven't used it.

In my case, the doesRequireAuditTrail will be less dependent on who the user 
is as what the Entity being edited is or what day it is. So, if I'm the user, 
the auditing may not happen today but may be required tomorrow.

Thanks for your thoughts.

Re: D2W - execute custom code on save changes

[Kieran Kelleher]

OK, so you can use any twisted logic you want to set a flag in ERXThreadStorage 
per request. Set the flag to true or false in some special logic in 
Session.awake maybe. I bet there is even a way to push a key in 
ERXThreadStorage using D2W rules based on certain logic ... maybe.

ERXThreadStorage is just a dictionary that is visible to the thread (a 
ThreadLocal variable) and works on the basis that each request/response is 
handled in a single thread. It gets cleared automatically at the end of a 
request. So you can push stuff in there anytime during a request and pull stuff 
out in totally unrelated places (for example in EOF), and still maintain 
separation of dependencies ... aka, not referring to appserver layer in the EOF 
layer. Very useful.

Regards, Kieran

Migrations and subsequent changes to DB model

[Farrukh Ijaz]

Hi All,

I'm using Migrations for the first time. I generated Migration for my model. I 
created a blank db and use Migration so the db is up to date. How the 
subsequent changes to the db will be handled using Migrations? Do I need to 
prepare SQL scripts manually or generating Migration again can detect the 
change and generate the code accordingly?

Thanks,

Farrukh ___

Ahg! No. :-)

 or generating Migration again can detect the change and generate the code 
 accordingly?

No, unfortunately generating the migration again will regenerate everything. 
After the initial migration, you'll need to manually write a new migration 
class, or do generate and manually remove the duplicate stuff - whichever is 
less work in your situation.

Basically create a second model class and increment the number from 0 (which 
is what your first migration class should have) to 1, eg MyModel1.java

Basically, Migrations will check to see if 0 was run, then it will look for the 
next class (by number) and then execute that one. And on and on and on.

Dave

ERModern* navigation changes

[David LeBer]

Hey all,

For those of you who are playing with apps based on ERModernMoviesDemo and do 
not follow the wonder commit list, I just committed changes to 
ERNavigationMenuItem that allow you to wrap the tab labels with an inner span 
eliminating the need for the Localizable.strings file hack.

I still recommend using Localizable.strings files, but now you can use them 
specifically for localization.

The inner spans are disabled by default and can be enable by adding the 
following property to your app:

er.extensions.ERXNavigationManager.includeLabelSpanTag=true

D2W-ListPageInterface using EOArrayDataSource doesn't display Changes?

[Dieter Stollorcz]

Hi all,

I am using the following code in the Session of a D2W-WonderApplication.

 public WOComponent listAnzeigengruppe() {
  ListPageInterface lpi = 
(ListPageInterface)D2W.factory().pageForConfigurationNamed(ListAnzeigengruppe,this);
 
  EOArrayDataSource ds = new 
EOArrayDataSource(EOClassDescription.classDescriptionForEntityName(Anzeigengruppe),
 session().defaultEditingContext() );
ds.setArray(bpAnzeigengruppeList());
  lpi.setDataSource(ds);
  return (WOComponent)lpi;
  }
After an update, delete or insert from this ERD2WListPage those changes are 
saved to the database but not displayed on the ListPage.


Using an EOFetchSpecification like the following works as expected.
...
EODatabaseDataSource ds = new EODatabaseDataSource(ec, 
Anzeigengruppe);
EOFetchSpecification fs = new EOFetchSpecification(Anzeigengruppe, 
qual, null);
ds.setFetchSpecification(fs);
ListPageInterface lpi = (ListPageInterface) 
D2W.factory().pageForConfigurationNamed(ListAnzeigengruppe, this);
lpi.setDataSource(ds);
return (WOComponent) lpi;
}

Isn't it possible to use an EOArrayDataSource in this case or am i doing 
something wrong?

This means your class path is incorrect. Adjust it so that

Right. When working in Eclipse, you just use the normal run/debug. By  
using the instructions I just sent, when you do Right-click - WOLips  
Ant tools - Install it will build a .war file that will run in  
Tomcat on any platform! I've run my wo projects on Mac, Windows  
(shudder) and Linux with _no_ modifications.


Long-term, you should look at setting up a build server like Hudson to  
do this for you automatically every time you commit to SVN/CVS.


You do use version control, don't you!? :-)

Hi Laurent,

How are you building your deployment? I have used WO with Tomcat lots
of times and have no troubles. There are specific options you can
check in WOLips to have it build a .war file that Tomcat will
automatically expand and run.

David can you send me your web.xml file (from your linux platform) please.

It's very strange, it's there a file to set the platform we use, I am using

Theres the problem.Note the first Prerequisite on the page I directed you to: "Eclipse 3.4  WOLips 5640 or laterinstalled."Everything I've been saying about how easy servlet development is, is because WOLips 3.4.5640 and later(aka "New Hotness" - Which requires Eclipse 3.4.2)have substantially revised servlet, framework-embedding and classpath-management functionality.New Hotness is pretty-much a mandatory upgrade. If you aren't using it (It's been around as Stable for almost a year now) then there's few people here that can help, because, as you are learning, servlet stuff was pretty bad before. It will probably take you longer to make servlets work out of 3.3 than the upgrade process will take you.See here:http://wolips.blogspot.com/2008/09/its-alive.html for instructions on how to upgrade your existing project to a New Hotness project.

That looks old.  Is this from a command line build?  If so, you have  
an old woproject.jar that Ant is using.

I don't touch the web.xml file that is created by Ant when my

I take the war file and drop it into Tomcat on Mac or Windows and it  
just works. It's been over a year since I dropped it into Tomcat on  
Linux, but it did run.


Did you follow the instructions at the link I sent?

It's very strange, it's there a file to set the platform we use,

No. In this situation, Java is Java and Tomcat is Tomcat. The  
platform is irrelevant (in my experience) when simply running one  
instance of a WO app in a servlet container.




I am using ERExtension framework, and it's appears nowhere in my war.

Which version of Eclipse/WOLips are you running?

That's strange, because this eclipse (3.4.2) didn't use wolips before ...

I created a new project, this the build.xml of a new wonder application.

when db schema changes... al goes wrong

[Gustavo Pizano]

Hello, long time without posting any question, I was assigned a iphone  
project, and now back to WO.


Here at work decided to change  the db schema, and add some more table  
and relationships, but they are not new apart from the ones I had  
already, they actually will touch the schema I was working on and the  
logic I was working with.


So, pain in the behind for me.

Im using migrations, this should work for something no?, when I create  
the new migration page then it complains that everything already  
exists!, and I can't delete anything otherwise.. all data goes to hell.



then I dunno if my design is that poor or what but I will have to  
touch the components that were doing something in the db in that  
specific area that its gonna be modified... so to keep avoiding this  
problems inthe future what suggestions you may have for me


I wanna cry I have to arrive on monday and start working on those  
changes, I was just todl today that they are waiting for me... great  
bday present I will have at the office on monday,

Each migration is a delta between the current state of the database  
and the previous state of the database.


In your myModelMigration0.java the migration includes everything to  
build the schema to step 0 (since nothing existed before).
In your myModelMigration1.java include only the additions to the  
schema necessary to build to step 1 (since step 0 is already completed).
In your myModelMigration2.java include only the additions to the  
schema necessary to build from step 1 to step 2 (since step 1 is  
already completed).

...
In your myModelMigrationN.java include only the additions to the  
schema necessary to build from step N-1 to step N (since step N-1 is  
already completed).

EOEditingContext has ObjectsChangedInEditingContextNotification, but  
it is on an object by object basis, not a key by key one.


You could implement this in your EO super class.

Re: Listening for changes on an EO

[Simon McLean]

also, if you are using wonder, check out
hasKeyChangedFromCommittedSnapshot in ERXGenericRecord. maybe listen
for the notification mentioned by chuck, then use
hasKeyChangedFromCommittedSnapshot to check the particular key you are
looking at.

Re: Listening for changes on an EO

[Lon Varscsak]

Thanks.  I figured there was nothing built to do exactly what I
needed, but I figured I would ask.

Do you know if there is much overhead if I implemented this in my EO
superclass even if there were no observers?

 EOEditingContext has ObjectsChangedInEditingContextNotification, but it is
 on an object by object basis, not a key by key one.

 You could implement this in your EO super class.

EOF makes heavy use of notification.  I would not expect there to be  
much overhead.  You will probably want to qualify the notification  
with the EC (depending on what it is you are trying to do) to limit  
the number of observers.  And then keep the method receiving the  
notification fast.  The notifications are synchronous, so you don't  
want anything slow in this method.

Re: Listening for changes on an EO

[Lon Varscsak]

Uh, another question. :)  Since I have a custom EO super-super class,
I decided to try to implement this in takeStoredValueForKey(..).

It works, although I was also trying to post the old value, and
asking for this current value at this point makes EOF not so
happy...but that's not strictly required for my needs.

However, it does post notifications even for fetched objects, what
would be the best way to only post changes after fetching?

Thanks again,

Lon

Re: Listening for changes on an EO

[Mark Morris]

Just a clarification, do you want to know when the value changes, even  
if it's not saved to the database?  Or do you just want to know if a  
change is being saved?  That would make a difference.  ;-)

Mark

Re: Listening for changes on an EO

I want to know if it's being changed.  I have a controller object that
will need to recalculate some values when a specific attribute changes
in the EO.
