• NSSortDescriptor for NSFetchRequestController causes crash when value of sorted attribute is changed

  - by AJ

  I have an Core Data Entity with a number of attributes, which include amount(float), categoryTotal(float) and category(string) The initial ViewController uses a FethchedResultsController to retrieve the entities, and sorts them based on the category and then the categoryTotal. No problems so far. NSManagedObjectContext *moc = [self managedObjectContext]; NSEntityDescription *entityDescription = [NSEntityDescription entityForName:@"Transaction" inManagedObjectContext:moc]; NSFetchRequest *request = [[[NSFetchRequest alloc] init] autorelease]; [request setEntity:entityDescription]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(dateStamp >= %@) AND (dateStamp =< %@)", startDate, endDate]; [request setPredicate:predicate]; NSSortDescriptor *sortByCategory = [[NSSortDescriptor alloc] initWithKey:@"category" ascending:sortOrder]; NSSortDescriptor *sortByTotals = [[NSSortDescriptor alloc] initWithKey:@"categoryTotal" ascending:sortOrder]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortByTotals, sortByCategory, nil]; [request setSortDescriptors:sortDescriptors]; NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:request managedObjectContext:managedObjectContext sectionNameKeyPath:@"category" cacheName:nil]; aFetchedResultsController.delegate = self; self.fetchedResultsController = aFetchedResultsController; On selecting a row (tableView:didSelectRowAtIndexPath), another view controller is loaded that allows editing of the amount field for the selected entity. Before returning to the first view, categoryTotal is updated by the new ‘amount’. The problem comes when returning to the first view controller, the app bombs with *Serious application error. Exception was caught during Core Data change processing: Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (1) must be equal to the number of rows contained in that section before the update (1), plus or minus the number of rows inserted or deleted from that section (0 inserted, 1 deleted). with userInfo (null) Program received signal: “EXC_BAD_ACCESS”.* This seems to be courtesy of NSSortDescriptor *sortByTotals = [[NSSortDescriptor alloc] initWithKey:@"categoryTotal" ascending:sortOrder]; If I remove this everything works as expected, but obviously without the sorting I want. I'm guessing this is to do with the sorting order changing due to categoryTotal changing (deletion / insertion) but can't find away fix this. I've verified that values are being modified correctly in the second view, so it appears down to the fetchedResultsController being confused. If the categoryAmount is changed to one that does not change the sort order, then no error is generated I'm not physically changing (ie deleting) the number of items the fetchedResultsController is returning ... the only other issue I can find that seem to generate this error Any ideas would be most welcome Thanks, AJ

• Does UrlDecode handle plus (+) correctly?

  - by harpo

  According to RFC 2396, The plus "+", dollar "$", and comma "," characters have been added to those in the "reserved" set, since they are treated as reserved within the query component. Indeed, search this site for "plus + comma , dollar $", and you get http://stackoverflow.com/search?q=plus+%2B+comma+,+dollar+$ Plus is only encoded (by the application) when it's not being used as a delimiter. But as others have observed, .NET's UrlDecode function converts plus to space. Where is this behavior specified?

• Print/save full webpage as PDF

  - by Oliver

  I need a method to be able to print/save the current full webpage as a PDF. I know it can be done if I download a PDF printer and print to that; but I need it to be done without the user having to do anything other than click a button in a webpage. I can't do it via PHP as the page is all client side content, so I'm guessing an ActiveX component? Any ideas would be greatly appreciated! Many thanks

• FluentNHibernate - AutoMappings producing incorrect one-to-many column key

  - by Alberto

  Hi I'm new to NHibernate and FNH and am trying to map these simple classes by using FluentNHibernate AutoMappings feature: public class TVShow : Entity { public virtual string Title { get; set;} public virtual ICollection<Season> Seasons { get; protected set; } public TVShow() { Seasons = new HashedSet<Season>(); } public virtual void AddSeason(Season season) { season.TVShow = this; Seasons.Add(season); } public virtual void RemoveSeason(Season season) { if (!Seasons.Contains(season)) { throw new InvalidOperationException("This TV Show does not contain the given season"); } season.TVShow = null; Seasons.Remove(season); } } public class Season : Entity { public virtual TVShow TVShow { get; set; } public virtual int Number { get; set; } public virtual IList<Episode> Episodes { get; set; } public Season() { Episodes = new List<Episode>(); } public virtual void AddEpisode(Episode episode) { episode.Season = this; Episodes.Add(episode); } public virtual void RemoveEpisode(Episode episode) { if (!Episodes.Contains(episode)) { throw new InvalidOperationException("Episode not found on this season"); } episode.Season = null; Episodes.Remove(episode); } } I'm also using a couple of conventions: public class MyForeignKeyConvention : IReferenceConvention { #region IConvention<IManyToOneInspector,IManyToOneInstance> Members public void Apply(FluentNHibernate.Conventions.Instances.IManyToOneInstance instance) { instance.Column("fk_" + instance.Property.Name); } #endregion } The problem is that FNH is generating the section below for the Seasons property mapping: <bag name="Seasons"> <key> <column name="TVShow_Id" /> </key> <one-to-many class="TVShowsManager.Domain.Season, TVShowsManager.Domain, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" /> </bag> The column name above should be fk_TVShow rather than TVShow_Id. If amend the hbm files produced by FNH then the code works. Does anyone know what it's wrong? Thanks in advance.

• How can I make xmlpp::DomParser less verbose on errors?

  - by Beau Simensen

  How can I make xmlpp::DomParser be less verbose on errors? Right now, if parsing fails, I get a bunch of text printed to my console and I'd just as soon have that not be visible. Entity: line 1: parser error : Opening and ending tag mismatch: feed line 1 and fed <feed><entry id='5' /></fed> I don't see a lot of options for xmlpp::DomParser but I have to believe this is something that can be disabled/tweaked.

• XS:Group causes Schema to fail validation

  I have an XML document based on a Schema that uses the xs:group element to bunch elements together. The result is an entity where name, address and phone number are defined in a group. This fails Schema validation in MS (Visual Studio) as well as XERCES (oXygen XML editor) Is there a workaround?

• App losing db connection

  - by DaveKub

  I'm having a weird issue with an old Delphi app losing it's database connection. Actually, I think it's losing something else that then makes the connection either drop or be unusable. The app is written in Delphi 6 and uses the Direct Oracle Access component (v4.0.7.1) to connect to an Oracle 9i database. The app runs as a service and periodically queries the db using a TOracleQuery object (qryAlarmList). The method that is called to do this looks like this: procedure TdmMain.RefreshAlarmList; begin try qryAlarmList.Execute; except on E: Exception do begin FStatus := ssError; EventLog.LogError(-1, 'TdmMain.RefreshAlarmList', 'Message: ' + E.Message); end; end; end; It had been running fine for years, until a couple of Perl scripts were added to this machine. These scripts run every 15 minutes and look for datafiles to import into the db, and then they do a some calculations and a bunch of reads/writes to/from the db. For some reason, when they are processing large amounts of data, and then the Delphi app tries to query the db, the Delphi app throws an exception at the "qryAlarmList.Execute" line in the above code listing. The exception is always: Access violation at address 00000000. read of address 00000000 HOW can something that the Perl scripts are doing cause this?? There are other Perl scripts on this machine that load data using the same modules and method calls and we didn't have problems. To make it even weirder, there are two other apps that will also suddenly lose their ability to talk to the database at the same time as the Perl stuff is running. Neither of those apps run on this machine, but both are Delphi 6 apps that use the same DOA component to connect to the same database. We have other apps that connect to the same db, written in Java or C# and they don't seem to have any problems. I've tried adding code before the '.Execute' method is called to: check the session's connection (session.CheckConnection(true); always comes back as 'ccOK'). see whether I can access a field of the qryAlarmList object to see if maybe it's become null; can access it fine. check the state of the qryAlarmList; always says it's qsIdle. Does anyone have any suggestions of something to try? This is driving me nuts! Dave

• How to stop debugging (or detach process) without stopping the process?

  - by Valentein

  I often use VS 2008 to debug a .NET C# component of an application. Sometimes, I want to quit debugging and continue running the application. Stop Debugging kills the process I was debugging. How can I achieve my aim? This is not a web app, it's a local process that runs managed and unmanaged code. I don't see any "Detach" or "Detach All" option in the Debug menu (is it enabled in some option?).

• What is a 'better' approach to query/save from server: DTO or Wcf Data Services?

  - by bonefisher

  From my perspective, the Data Services and their query approach is useful when querying simple object graphs from your server-side domain model. But when you want to query complex dependencies I couldn't create anything good out of it. The classic DTO approach is fine-grained and can handle everything, but the downside is that you have to create Dto classes for every type of server-request which is time consuming and you have to synchronize the Dto type with your domain entity/business logic.

• Is there an XmlWriter that writes a colorful HTML-formatted output for displaying XML in a webpage?

  - by Vilx-

  I've got a bit of XML I want to display on my ASP.NET website as-is (for debugging purposes), and it would be nice if it was colored. This should be easy to achieve with the right kind of XmlWriter, but I don't have the time to make one myself. Is there an existing (free) component that can do this?
