Re: EOF - statement has been closed?
Hey Chuck et al, This is a follow-up question for you. I'm doing things like the code shown below in quite a few places. I'm assuming the ERXEC's are locked automagically as normal during the RR loop, but are you saying I also need to explicitly lock the EODatabaseContext in this case? Do I need to manually lock the EC too? When do these things need to be manually locked? Do I need to manually lock the EC when I'm getting a ref. to the EOModel, EOAttributes, etc...? EODatabaseContext db = EOUtilities.databaseContextForModelNamed(editingContext(), myModel); EOSQLExpressionFactory sqlFactory = db.adaptorContext().adaptor().expressionFactory(); EOSQLExpression exp = sqlFactory.createExpression(al); exp.setUseBindVariables(true); exp.setStatement(sql); //set the values exp.addBindVariableDictionary( exp.bindVariableDictionaryForAttribute(al.attributeNamed(Al.E_KEY), user().e().id())); exp.addBindVariableDictionary( exp.bindVariableDictionaryForAttribute(al.attributeNamed(Al.U_KEY), user())); exp.addBindVariableDictionary( exp.bindVariableDictionaryForAttribute(al.attributeNamed(Al.AL_KEY), AlEnum.GSTONE)); exp.addBindVariableDictionary( exp.bindVariableDictionaryForAttribute(al.attributeNamed(Al.AL_KEY), AlEnum.GSTRATEGY)); //execute the query NSArrayNSDictionary rows = ERXEOAccessUtilities.rawRowsForSQLExpression(editingContext(), myModel, exp); return ((BigDecimal) rows.get(0).valueForKey(NUMBER)).intValue(); Thanks. -Mike On Mar 21, 2013, at 1:42 PM, Michael Gargano wrote: I've checked this in our code several times, there is another app where we do stuff like that, but not in this one.

postgres jdbc driver
Hi all, Just taking a quick survey of folks using postgres. I think we've found an issue with the jdbc driver (any version within the last year or so). Since people don't update the jdbc drivers too frequently. What version of driver are you on? Has it been stable under heavy load? Thanks. -Mike ___ Do not post admin requests to the list.

RE: postgres jdbc driver
The statement is closing at random times and it eventually ends up hanging eof and locking the instance. It looks like others have found an issue with the postgres jdbc driver doing this under heavy load, it's all in the statement pooling (some kind of race condition). I've been trying to debug this for months. I'm on pg 9.0. -Mike From: Ramsey Gurley [mailto:rgur...@smarthealth.com] Sent: Wednesday, March 06, 2013 11:59 AM To: Michael Gargano Cc: WebObjects-Dev List (webobjects-dev@lists.apple.com) Subject: Re: postgres jdbc driver Out of curiosity, what sort of issues are you seeing?

RE: WOWorkerThread deadlocks
Hi guys, I know I'm a little late on this, but I'm also seeing the same behavior. It's not a long running query I don't think because I'm logging long queries in postgres and nothing is running over 10 seconds. Can you explain why having a max of 256 worker threads is too high? Any other things I should look at? The customers are not happy! My last problem did turn out to be a bunch of deadlocks, which all now seem to be resolved. It had to with setting er.extensions.ERXObjectStoreCoordinatorPool.maxCoordinators=4 which should be seamless (you would think) but causes issues with fetch specs that have EOs crossing OSCs. I had to pull all EOs local, seems like something that should be handled inside wonder automatically (so I consider it a bug, whether it is or not could be argued I guess). Anyway, after those all got fixed, I'm now running into this. Much harder to figure out since I don't even know what the lock is held on. BTW Chuck and Quinton, I owe you guys a beer.

Re: production hanging
Some more info on this that I just found. This doesn't happen under load when concurrent dispatch is disabled. Now is that a bug in wonder or in my app.? -Mike On Nov 30, 2012, at 1:25 PM, Michael Gargano wrote: okay guys, you were right... it's a deadlock the worst of all possible worlds. I've included the trace below for one of the deadlocks. I keep getting two deadlocks at the time the app goes down. I can't quite figure out why, it seems like it's always in the same one or two places, but there's nothing so different about those spots that it shouldn't lock for the same reasons in a million other places in the app. I'm only doing fetches in these methods where it breaks and my guess is, that since I have 4 coordinators going, the four threads involved (between the two deadlocks) are locking the coordinators and bringing all the other threads to a grinding halt. It almost looks to me like a bug in the auto-locking. Can one thread be accessing multiple coordinators? I almost feel like one of the EOs I'm getting out of my default session store, that is being used in a fetch spec with an EO from the editing context on the page, are locking across two different store coordinators.

production hanging
Hi all, I'm having an issue in our production environment. I have two servers (vm's w/ windows 2008 r2 64-bit) running two instances each. The servers are load balanced by a hardware load balancer that pings the app on each box every minute to determine if it is still up (because of the way our app works, this creates a session). After about a week of uptime, the each app instance seems to just stop responding to requests one at a time until no instances respond any more. The java processes are still always running, but nothing responds. I recently bumped up the mem. on the apps to 3G each, to see if that would help, but the same problem occurred.

Re: Postgresql and ERXSQLHelper
Just some follow up on this It turns out this had to do with being headless. As soon as initApp was added (or when I turned it into a full fledge WO app) the problem went away. I'm not sure what additional work is being done in initApp, but this is clearly a bug when running headless. I wish I knew where to look to fix it, but nothing that initApp does jumped out at me as something that was missing in initEOF. -Mike On Mar 16, 2012, at 6:35 PM, Michael Gargano wrote: Okay, I'm not sure how to explain this, but here it goes...

migrations with multiple software versions
Hi all, I have a little scenario here and I was wondering if there was a way the ERXMigration system could handle it. It looks like a no just reading some of the docs, but I can't be the only one doing this (i hope). So, I have two versions of software being worked on simultaneously. The version 1 branch is stable with point releases introducing new features and the version 2 branch is a fairly major revision simultaneously undergoing major development. version 1.0 _ version 1.1__ version 1.1.1 __ version 1.2.0 /_. \version 2.0 development The question is... is there a good way to mange migrations with this sort of setup? It seems like the migration system is really designed more to handle a linear progression only. Is there even a way to spilt the migration classes of a particular model into separate packages to better manage the migrations across different versions of the software? I understand that as I add things to the version 1 branch that there will be potential conflict in the version 2 branch, but my question is more like do I start the version 2 migration numbers at like 200 and leave room for ~90 potential future version 1 migrations and if i did that does that mean I would need to create ~90 actual classes that do nothing (obviously, this is not really a good solution) Any thoughts or ideas on this are appreciated.

ERXObjectStoreCoordinatorPool exception
Hi again, I just configured the ERXObjectStoreCoordinatorPool have 4 coordinators using the ERJGroupSyncronizer. I have 2 application servers running 2 apps each. The apps on each box talk to each other and both servers share one DB. Server A Server B --- --- myApp myApp taskRunnerApp taskRunnerApp \ / DB Server Everything seems to be running okay, but now that I've turned on the coordinator pool I see this strange exception.

Re: Interesting DisplayGroup EOEditingContext Interaction
After more testing and playing today. It seems that the refresh of the ERXBatchingDisplayGroup is sporadic at best. I tried using just the fetch() and the status field never updated, setting the qualifier to the current qualifier seems to work more often then not, but it still does not work consistently. However, forcing a page refresh in one browser still seems to consistently update the other browser. At the end of the day, I just don't want the display group to cache any of the records on this page.

Interesting DisplayGroup EOEditingContext Interaction
Hey dev. group, As I was working on one of my application pages today I noticed something that I couldn't explain and was hoping one of you nice folks could shed some light on it. -Setting the stage- One of the pages I'm working on has an AjaxGrid that is periodically (5 secs.) refreshed from an AjaxUpdateContainer. When the update container fires, it calls an action that calls displayGroup.setQualifier(displayGroup.qualifier()) to refresh the ERXBatchingDisplayGroup as noted in the JavaDoc and by Chuck in previous posts. Now the reason this grid is being updated is because I'm running processes in the background and the grid shows the status of the processes (qualified by user). This way I can see when the task completes. Easy enough It seems to work great. -The dilemma- Now here's what I don't get. If I log into the application as the same user from two different machines... When I start a new process on one machine both of the grids update showing that a new process is running (as expected), but neither ever update the grid when the process is completed. If I reload the page on one machine, it updates the status and then subsequently the other machine refreshes with the correct status, but I need to poke it. I don't understand why it works fine on the individual machines when I'm logged in only once and acts like this when I have two browsers refreshing the same data. The page generates a new EC. I'm guessing it's some kind of weird locking issue, but I can't figure out what's locking. I'm using optimistic locking and on top of that, these are only reads. Thanks.

AjaxObserveField observeFieldFrequency problem
Anyone ever encounter this? I have a CCAjaxTab and inside each tab is a AjaxObserveField observing a text field and, somewhere else in the tab, an update container. the AjaxObserveField has an observeFieldFrequency of 1. everything works fine except in IE (of course) when you click on another tab. An alert box pops up from wonder.js (line 379) complaining that it can't find the update container ID of what is being observed on the tab I just came from because that tab content has now been replaced. Anyone have ideas of how I can stop the observing before switching tabs or any other suggestions? Thanks. -Mike ___ Do not post admin requests to the list. They will be ignored.

Re: EOF validation messages questions
Hi Ramsey, Okay, so you helped me quite a bit here, but of course I have a few follow-up questions. :-D 1) (the easier one) how do I change the name for an entity in the localization file? 2) When a validation exception comes from a formatter (the java.text.Format) on a text field, the exception is a NSValidation.ValidationException which does not have a context like the ERXValidaion does. Also, because it is thrown before it has anything to do with EOF, there is no attribute or eo associated with it, so in the contextForException method you don't even know what form is throwing it. How is this usually handled, because this is giving me the following error... The value entered for ? is not valid. I can grab it on the page in validationFailedWithException, but again there's no way to set the context. I'm surprised by how confusing this is for such seemingly simple task. Thanks again. -Mike On Oct 19, 2011, at 6:54 PM, Ramsey Gurley wrote: On Oct 19, 2011, at 3:41 PM, Michael Gargano wrote: Hi Ramsey, I'm a little confused here.

I had that problem the other month on all my attributes, but it had to with the d2w libs I had in the build path at the time, those are gone now and I don't know why this happens or the best way to handle it. In ERExtensions ValidationTemplate.strings file I see: ValueConversionException = The value entered for b@@displayNameForProperty@@/b is not a valid b@@attribute.valueClass@@/b.; The display name for your property is created correctly because there is a displayNameForProperty() method on ERXValidationException. There's no attribute() method on ERXValidationException, so it goes to the validation context object for an answer. If you don't have a validation delegate to supply a context and you haven't set a context manually, you end up with a '?' replacement character. 2) Somewhat related to this... I have some EO attributes with names that make sense in the business domain, but should be called something else when surfaced to the user. So, the attribute might be fancyBusinessObjectName, but when I catch the exception and show the message I want it to be displayed as User Non Scary Name. Is there a way to do either of these things without just doing string replacements on the message from the exception, perhaps something in userInfo? Thanks. -Mike In the example above, you could add something like: PropertyKey.fancyBusinessObjectName = User Non Scary Name; To your english strings file and get the desired results. It's also done as MyEntityName.fancyBusinessObjectName = User Non Scary Name; In some places. Not sure which will work for you. Ramsey ___ Do not post admin requests to the list.

Re: Entity Validation Exception Question
Hi Ramsey, Sorry, I'm still a little confused with this one. I see what you are saying about the context, but I don't know how to find which keys to use. The messages that are getting generated by validation produce things like Please provide ? Name. From what I looked at in the code yesterday, I guess the '?' is supposed to be the entity name. Why does the property resolve properly, but not the entity name? And where do I look to find the valid keys for the context?

Re: Entity Validation Exception Question

validation question
Hi everyone, I have an EO with let's say 3 attributes. Name (String, not nullable, 255 chars) short desc (String, not nullable, 255 chars) long desc (String, nullable, 2000 chars) in the ui, name and short desc are attached to wotextfields and long desc is a wotext if i put more than 2000 chars in the long desc text box and leave the other two fields blank, i get all three validation errors (name and short desc cannot be null and long desc is over 2000 chars) just as expected. however if i fill in name and short desc properly and put more than 2000 chars in the long desc text box the EO gets saved to the DB. upon inspection of the record, the long desc attribute is just nullified. i see the exception being thrown in validateValueForKey, but since all the validations get called twice, it looks like the first time around the exception is thrown, swallowed by something that then nulls that value, and on the second time around since that attribute is nullable, it's just stores it straight to the DB. it looks like others have had similar problems on the mailing list in the past, i couldn't seem to find a resolution though.

The AMD Opener then stashes object() in the thread/page/session/as you like
for the dialog to use. My pages have a concept of selected object or
focused object
also, this is probably a dumb question, but there's no way to pop and push
modal dialogs on top of one another? My spec calls for a modal dialog that
has another modal on top of it for selection inside the 1st modal dialog (i
just work here).
:-)
i starting writing a component myself, but when I needed to make it ajax-y i
turned and started running the other way.
I don't think there is a way. The reason is that the underlying JavaScript
implementation just allows for one to be displayed at a time. You would have
to close one and open the other, or update the contents of the current one
with the other one. I'd look at that or something like an expansion area.

Re: Using DataGrid in WO
Hey Chuck,
This is from a few months ago, but how exactly are you passing your selected
row into the dialog to edit it? I can't figure this out since I'm using a
custom cell in the grid to do this. the custom cell has an
ajaxmodaldialogopener with an image in it.
are you just directly using ajaxmodaldialogopener as the custom component?

I don't use AjaxModalDialog but AjaxModalDialogOpener.
But... you do have an AjaxModalDialog that the AjaxModalDialogOpener is
opening, right? If you don't, you are not using the AjaxModalDialogOpener
correctly. If you do have an AjaxModalDialog (even if it is in a different
component), then the closeUpdateContainerID goes in that WOD definition.
Can I surround AjaxModalDialogOpener with AjaxModalDialog ?
No. See how they are used in the AjaxExamples application in Wonder. You
also should not have a submit button inside the AjaxModalDialogOpener:
wo:AjaxModalDialogOpener id=refreshGrid
wo:AjaxSubmitButton action=$addSelectedPerson value=addPerson
/wo:AjaxModalDialogOpener
Where I insert AjaxModalDialog in my code to refresh my grid? My
AjaxModalDialogOpener is on the good side in html code?
The AjaxModalDialog was to edit the information shown in your grid.

In the plist that has your grid configuration, add a line like this:

Then in the WOD that defines the dialog:

ajaxgrid and d2w
If anyone knows... I'm guessing there is no easy way to use ajaxgrid with d2w. I'm assuming I'd have to write my own look to do something like this which would involve me mostly rewriting ajaxgrid to cram the d2w content into it. If anyone has any suggestions I'm open.

Re: ajaxgrid and d2w
Hi David, So, it's just a List Page that's been Ajax-ified. It doesn't even have an associated component, so, it's completely not embeddable in my application. I got so close with ERModern, but unfortunately every other grid in the app is an ajax grid and it just wouldn't look right. I guess that kills D2W for me. So, sad. If I knew more and had more time I might try to do this on my own, but Anjo's code looks crazy and depends heavily on YUI. Thanks anyway. -Sad Panda :( (I mean...

Re: woswitchcomponents

That's pretty easy to use. Just include your list of ERXAuditKeys in the userInfo dictionary for the Entity and it handles the rest. If you include the ERXAuditKeys key with an empty value, it will log all your attributes by default. Also, the existing audit trail handler doesn't support flattened relationships (many-to-many's) so well, but you can provide your own audit trail handler subclass via a property if you need that. If you want to track who makes changes, you'll also need to set up an actor entity. Otherwise, you just track changes. Most everything you need to know happens in ERCAuditTrailHandler.java.

d2w - huh?
Hi all, I'm trying to integrate d2w into my app and when I change the rules no updates seem to ever take hold. I've tried clearing the d2w cache, but the only thing that seems to work is cleaning the project several times. I had a stand alone wonder d2w app to just play with and everything was working fine, now that app has the same problem too. Very strange. Also, if I grab the queryAll page I run out of heap space after about 5-6 refreshes of the page. I hope I'm just doing something stupid here. Any ideas?

Re: Mismatch between model and database
Hi Pascal, This sounds like our stuff that you're working on. I think I had an open question to the list on this actually. For some reason, when a model is reverse engineered and a prototype is incorrectly assigned to a column this error seems to occur. The reverse engineering process is making the assumption that if a column's data type matches a prototype, that attribute must be of that prototype's type. This is clearly incorrect though. For example you may just have a column that is varchar(5), it's not necessarily a boolean prototype. It would be good if the prototype mapping can be turned on/off when reverse engineering. The only solution I've found is to go through and manually remove the prototypes, so that's what I've been doing. The problem is the next time I need to refresh the mapping and rev. eng. the newer tables, prototype removal will need to be done again. -Mike On Jun 2, 2011, at 2:47 PM, Pascal Robert wrote: I'm getting some mismatch types for an attribute that is part of a model that was created from reverse engineering. Look like it's a mismatch between a String type and a number column, but sadly the exception is not saying which column or attribute it is, and no success by using breakpoints. Is there a trick to find which column is the problem? Checking manually more than 150 attributes would be a real PITA :-) Thanks. juin 02 14:37:33 eGM[49754] WARN NSLog - er.ajax.AjaxRequestHandler: Exception occurred while handling request: N/A [2011-6-2 14:37:33 EDT] WorkerThread8 N/A at com.webobjects.jdbcadaptor.JDBCColumn.takeInputValue(JDBCColumn.java:621) at com.webobjects.jdbcadaptor.JDBCChannel._bindInputVariablesWithBindingsAndExecute(JDBCChannel.java:260) at com.webobjects.jdbcadaptor.JDBCChannel._evaluateExpression(JDBCChannel.java:337) at com.webobjects.jdbcadaptor.JDBCChannel.evaluateExpression(JDBCChannel.java:296) at com.webobjects.jdbcadaptor.JDBCChannel.selectAttributes(JDBCChannel.java:220) at com.webobjects.eoaccess.EODatabaseChannel._selectWithFetchSpecificationEditingContext(EODatabaseChannel.java:897) at com.webobjects.eoaccess.EODatabaseChannel.selectObjectsWithFetchSpecification(EODatabaseChannel.java:234) at com.webobjects.eoaccess.EODatabaseContext._objectsWithFetchSpecificationEditingContext(EODatabaseContext.java:3055) at com.webobjects.eoaccess.EODatabaseContext.objectsWithFetchSpecification(EODatabaseContext.java:3195) at com.webobjects.eocontrol.EOObjectStoreCoordinator.objectsWithFetchSpecification(EOObjectStoreCoordinator.java:488) at com.webobjects.eocontrol.EOEditingContext.objectsWithFetchSpecification(EOEditingContext.java:4069) at er.extensions.eof.ERXEC.objectsWithFetchSpecification(ERXEC.java:1206) at com.webobjects.eocontrol.EOEditingContext.objectsWithFetchSpecification(EOEditingContext.java:) ...

Re: database design patterns for the desperate
Thanks Kieran,
Maybe something I wasn't clear about either is that the local user copy
can change attributes all the way across the structure. So, tB and tC will
have additional attributes as well and local values for attributes there too.
So, I understand doing that for tA, I guess I would need to have the same
procedure for tB and tC and the implementation of the EOCopyable interface
would have to create the local versions of the tB and tC objects when doing the
deep copy.
This is definitely an option. I'm not expecting it to be pretty.
My heart grows heavy with foreign key constraints.

getting a session from WOApplication dispatchRequest
Hi all,
I need to do something like this...
public WOResponse dispatchRequest(WORequest) {
session = getWOSession
retrieve / modify values in session
bind some thread local variables
response = super.dispatchRequest()
unbind the tread local variables
return response
}
I was trying to get the session from the request's context, but the context has
not be created at this point. So, there were two ways I was looking at
accomplishing this
1) call createContextFromRequest() to get a new context followed by
restoreSessionWithID
(this seems like the dicer of the two options)
2) call sessionStore() to retrieve the session store then call
restoreSessionWithID() to get a reference to the session make my reads and
changes
Chuck had mentioned doing this in Session's awake() and sleep(), but the
problem is that I'm trying to unify the WOSession with another framework's
session model, so some of the information I need to restore the other session
resides in the WOSession. The other framework also has a bunch of stuff it
binds to thread local, but everything works off it's own internal utility
classes preventing me from using ERXThreadStorage.
Thanks.

stoping models from loading into default EOModelGroup
Okay... two days... I give up...
Is there a way to stop a model from getting loaded into the default
EOModelGroup? I have a entity naming conflict and I want to prevent a model in
a framework I'm using from loading. I looked at the delegate methods and they
don't seem do do what I want, the EOModelGroup.ClassDelegate looked promising,
but from what I read it looks like I'd have to re-implement most of
ERXModelGroup.loadModelsFromLoadedBundles() and when I put this code...
// remove the my Model from the default model group of the Application
EOModelGroup.setClassDelegate(new EOModelGroup.ClassDelegate() {
@Override
public EOModelGroup defaultModelGroup() {
ERXModelGroup group = new ERXModelGroup();
group.loadModelsFromLoadedBundles();// pretty sure this would still throw an
exception
EOModel model = group.modelNamed(mymodel);
if(model != null)
group.removeModel(model);
return group;
}
});
... in the Application() constructor it get the message...
Class com.webobjects.foundation.NSSelector can not access a member of class
com.mycomp.Application$1 with modifiers public
If this can't be done I guess my only recourse would be to write a util.
program to edit all the plist from my models and prepend something to all the
entity names.
Thanks.

Re: model connections to multiple DBs
Sorry, I thought I replied all. Thanks. I'll start here. With overhead I
just mean that the setup for a new EOF stack must not be very fast and my guess

I haven't actually tried it and don't know what you mean by overhead, but
the core idea would be sth like:
public Session() {
EOModelGroup modelGroup = new EOModelGroup();
EOModel model = modelGroup.addModelWithPath(/some/where); // model should
be in a subfolder of Resources so it won't get loaded
adjustConnectionDict(model);
EOAdaptor adaptor = EOAdaptor.adaptorWithModel(model);
EODatabaseContext dbc = new EODatabaseContext(adaptor);
EOObjectStoreCoordinator osc = new EOObjectStoreCoordinator();
osc.addCooperatingObjectStore(dbc);
EOEditingContext ec = new EOEditingContext(osc);
setDefaultEditingContext(ec);
}
This probably won't even compile, but should get you started. All other ECs
must be created as
new EOEditingContext(session().defaultEditingContext().parentObjectStore())
or from a thread-local.

You can create one EOF stack per user and clone the model group so it's

EOModelGroup.defaultGroup() anywhere, though.

Re: PostgreSQL float8
Hi Ramsey and Ted, It seems like that is the issue. WONDER-693http://issues.objectstyle.org/jira/browse/WONDER-693 and WOL-1206http://issues.objectstyle.org/jira/browse/WOL-1206 Thanks guys. -Mike On Mar 27, 2011, at 12:42 PM, Ramsey Gurley wrote: Hi Ted, I've closed one like that already as it belongs on WOProject JIRA. Don't be offended if I close 517 for the same reasons... http://issues.objectstyle.org/jira/browse/WONDER-438 The problem appears to be in the migration generation template. It should be filed on JIRA for WOLips instead. I see http://issues.objectstyle.org/jira/browse/WOL-1029 which looks related. Maybe vote on that? Michael, I was not aware that the double migration itself did not work for Postgresql. File a jira for that issue on Wonder and I will take a look once I figure out git (^_^) I suspect all you need to do is add Type.FLOAT and Type.DOUBLE into that tremendous 'if' statement in PostgresqlSQLHelper.externalTypeForJDBCType().

Mimicking the J2EE filter chain
Hi all,
I'm using the Shiro security framework for the project I'm
working on. In the framework, the subject (basically the user) is bound to the
thread and unbound through the J2EE filter chain. My plan was to just shove
this subject object into the Session, but the authors of the framework really
suggest binding and unbinding this object to the request thread . The problem
is... I have no idea how that would be done in WO. Would I have to override
createRequest in Application? I was thinking something like...
createRequest(params...) {
Subject.execute(new Callable() {
public Object call() throws Exception {
super.createRequest(params...);
}
}
}
Any other suggestions? I'm not sure something like this would even work.
Thanks.
-Mike

Re: Indexes on Postgresql using EOF Modeler
I believe Mike S. said that indexes were added in 5.4 and the modeler doesn't support them because there's no API. You have to add them programmatically in your migration script. If you search the archives you can get his exact response. I asked in Oct. or Nov. last year. :) -the other Mike Sent from my iPhone On Mar 9, 2011, at 6:03 AM, Paul Dunkler paul.dunk...@xyrality.com wrote: Hi folks, i'm currently working with WOLipse and the EntityModeler for creating a postgres-driven database model. Everything works fine except the creation of indexes. I can create new indexes on tables, but they aren't included in the sql-output generated by the modeler. Only the indexes on the primary key attributes are generated (automatically), but no index which i defined by my self. Would be very nice if anyone now what to do, because i don't want to maintain my indexes in txt-documents or something ;) -- Best Regards Paul Dunkler ___ Do not post admin requests to the list.

Re: Localization
Okay,
So, for future reference (for myself mostly, I guess)
ERXLocalizer.currentLocalizer().takeValueForKey() works fine. I'm not sure
what these other methods do, but it's not what I want.

Hi all,
I'm having a issue with string localization
I have English.lproj and Spanish.lproj folders in my Resources directory with a
Localizable.strings file in each (both UTF-8). The files look like this
{
loginname = {
test = Test;
};
}
{
loginname = {
test = Prueba;
};
}
Now in my code I'm calling the following...
ERXLocalizer.currentLocalizer().localizedStringForKey(loginname.test);
I also tried...
ERXStringUtilities.localizedStringForKey(loginname.test);
I get nothing but nulls back. If I get rid of the dictionary, it works fine.
According to the JavaDoc in ERXLocalizer it appears that this should work.
Suggestions?
Thanks.
