  • Completed Event not triggering for web service on some systems

    - by Farukh
    Hi, This is rather weird issue that I am facing with by WCF/Silverlight application. I am using a WCF to get data from a database for my Silverlight application and the completed event is not triggering for method in WCF on some systems. I have checked the called method executes properly has returns the values. I have checked via Fiddler and it clearly shows that response has the returned values as well. However the completed event is not getting triggered. Moreover in few of the systems, everything is fine and I am able to process the returned value in the completed method. Any thoughts or suggestions would be greatly appreciated. I have tried searching around the web but without any luck :( Following is the code.. Calling the method.. void RFCDeploy_Loaded(object sender, RoutedEventArgs e) { btnSelectFile.IsEnabled = true; btnUploadFile.IsEnabled = false; btnSelectFile.Click += new RoutedEventHandler(btnSelectFile_Click); btnUploadFile.Click += new RoutedEventHandler(btnUploadFile_Click); RFCChangeDataGrid.KeyDown += new KeyEventHandler(RFCChangeDataGrid_KeyDown); btnAddRFCManually.Click += new RoutedEventHandler(btnAddRFCManually_Click); ServiceReference1.DataService1Client ws = new BEVDashBoard.ServiceReference1.DataService1Client(); ws.GetRFCChangeCompleted += new EventHandler<BEVDashBoard.ServiceReference1.GetRFCChangeCompletedEventArgs>(ws_GetRFCChangeCompleted); ws.GetRFCChangeAsync(); this.BusyIndicator1.IsBusy = true; } Completed Event.... void ws_GetRFCChangeCompleted(object sender, BEVDashBoard.ServiceReference1.GetRFCChangeCompletedEventArgs e) { PagedCollectionView view = new PagedCollectionView(e.Result); view.GroupDescriptions.Add(new PropertyGroupDescription("RFC")); RFCChangeDataGrid.ItemsSource = view; foreach (CollectionViewGroup group in view.Groups) { RFCChangeDataGrid.CollapseRowGroup(group, true); } this.BusyIndicator1.IsBusy = false; } Please note that this WCF has lots of other method as well and all of them are working fine.... I have problem with only this method... Thanks...

  • ViewController doesn't get released

    - by ObjectiveFlash
    Every time I turn the page in my app, I am removing and releasing the previous viewController - but for some reason it is still in memory. I know this, because after using the app for a while, I get 47 memory warnings - one from each view controller - if I had opened 47 pages before the memory warning occurred. I get 60 memory warnings if I had opened 60 pages before the memory warning occurred. And so on... This is the code that runs from page to page: UIViewController *nextController; Class nextClass = [pageClasses objectAtIndex:(currentPageIndex - 1)]; nextController = [[nextClass alloc] initWithNibName:[pageNibs objectAtIndex:(currentPageIndex - 1)] bundle:nil]; [nextController performSelector:@selector(setDelegate:) withObject:self]; [currentPageController.view removeFromSuperview]; [self.view addSubview:nextController.view]; [currentPageController release]; currentPageController = nextController; [currentPageController retain]; [nextController release]; Can anybody point to any issues they see? Thanks so much!

  • Problem persisting inheritance tree

    - by alaiseca
    I have a problem trying to map an inheritance tree. A simplified version of my model is like this: @MappedSuperclass @Embeddable public class BaseEmbedded implements Serializable { @Column(name="BE_FIELD") private String beField; // Getters and setters follow } @MappedSuperclass @Embeddable public class DerivedEmbedded extends BaseEmbedded { @Column(name="DE_FIELD") private String deField; // Getters and setters follow } @MappedSuperclass public abstract class BaseClass implements Serializable { @Embedded protected BaseEmbedded embedded; public BaseClass() { this.embedded = new BaseEmbedded(); } // Getters and setters follow } @Entity @Table(name="MYTABLE") @Inheritance(strategy=InheritanceType.SINGLE_TABLE) @DiscriminatorColumn(name="TYPE", discriminatorType=DiscriminatorType.STRING) public class DerivedClass extends BaseClass { @Id @Column(name="ID", nullable=false) private Long id; @Column(name="TYPE", nullable=false, insertable=false, updatable=false) private String type; public DerivedClass() { this.embedded = new DerivedClass(); } // Getters and setters follow } @Entity @DiscriminatorValue("A") public class DerivedClassA extends DerivedClass { @Embeddable public static NestedClassA extends DerivedEmbedded { @Column(name="FIELD_CLASS_A") private String fieldClassA; } public DerivedClassA() { this.embedded = new NestedClassA(); } // Getters and setters follow } @Entity @DiscriminatorValue("B") public class DerivedClassB extends DerivedClass { @Embeddable public static NestedClassB extends DerivedEmbedded { @Column(name="FIELD_CLASS_B") private String fieldClassB; } public DerivedClassB() { this.embedded = new NestedClassB(); } // Getters and setters follow } At Java level, this model is working fine, and I believe is the appropriate one. My problem comes up when it's time to persist an object. At runtime, I can create an object which could be an instance of DerivedClass, DerivedClassA or DerivedClassB. As you can see, each one of the derived classes introduces a new field which only makes sense for that specific derived class. All the classes share the same physical table in the database. If I persist an object of type DerivedClass, I expect fields BE_FIELD, DE_FIELD, ID and TYPE to be persisted with their values and the remaining fields to be null. If I persist an object of type DerivedClass A, I expect those same fields plus the FIELD_CLASS_A field to be persisted with their values and field FIELD_CLASS_B to be null. Something equivalent for an object of type DerivedClassB. Since the @Embedded annotation is at the BaseClass only, Hibernate is only persisting the fields up to that level in the tree. I don't know how to tell Hibernate that I want to persist up to the appropriate level in the tree, depending on the actual type of the embedded property. I cannot have another @Embedded property in the subclasses since this would duplicate data that is already present in the superclass and would also break the Java model. I cannot declare the embedded property to be of a more specific type either, since it's only at runtime when the actual object is created and I don't have a single branch in the hierarchy. Is it possible to solve my problem? Or should I resignate myself to accept that there is no way to persist the Java model as it is? Any help will be greatly appreciated.

  • No more memory available in Mathematica, Fit the parameters of system of differential equation

    - by user1058051
    I encountered a memory problem in Mathematica, when I tried to process my experimental data. It's a system of two differential equations and I need to find most suitable parameters. Unfortunately I am not a Pro in Mathematica, so the program used a lot of memory, when the parameter epsilon is more than 0.4. When it less than 0.4, the program work properly. The command 'historylength = 0' and attempts to reduce the Accuracy Goal and WorkingPrecision didn`t help. I can't use ' clear Cache ', because there isnt a circle. I'm trying to understand what mistakes I made, and how I may limit the memory usage. I have already bought extra-RAM, now its 4GB, and now I haven't free memory-slots in motherboard Remove["Global`*"]; T=13200; L = 0.085; e = 0.41; v = 0.000557197; q = 0.1618; C0 = 0.0256; R = 0.00075; data = {{L,600,0.141124587},{L,1200,0.254134509},{L,1800,0.342888644}, {L,2400,0.424476295},{L,3600,0.562844542},{L,4800,0.657111356}, {L,6000,0.75137817},{L,7200,0.815876516},{L,8430,0.879823594}, {L,9000,0.900771775},{L,13200,1}}; model[(De_)?NumberQ, (Kf_)?NumberQ, (Y_)?NumberQ] := model[De, Kf, Y] = yeld /.Last[Last[ NDSolve[{ v (Ci^(1,0))[z,t]+(Ci^(0,1))[z,t]== -((3 (1-e) Kf (Ci[z,t]-C0))/ (R e (1-(R Kf (1-R/r[z,t]))/De))), (r^(0,1))[z,t]== (R^2 Kf (Ci[z,t]-C0))/ (q r[z,t]^2 (1-(R Kf (1-R/r[z,t]))/De)), (yeld^(0,1))[z,t]== Y*(v e Ci[z,t])/(L q (1-e)), r[z,0]==R, Ci[z,0]==0, Ci[0,t]==0, yeld[z,0]==0}, {r[z,t],Ci[z,t],yeld},{z,0,L},{t,0,T}]]] fit = FindFit[data, {model[De, Kf, Y][z, t], {Y > 0.97, Y < 1.03, Kf > 10^-6, Kf < 10^-4, De > 10^-13, De < 10^-9}}, {{De,7*10^-13}, {Kf, 10^-5}, {Y, 1}}, {z, t}, Method -> NMinimize] data = {{600,0.141124587},{1200,0.254134509},{1800,0.342888644}, {2400,0.424476295},{3600,0.562844542},{4800,0.657111356}, {6000,0.75137817},{7200,0.815876516},{8430,0.879823594}, {9000,0.900771775},{13200,1}}; YYY = model[ De /. fit[[1]], Kf /. fit[[2]], Y /. fit[[3]]]; Show[Plot[Evaluate[YYY[L,t]],{t,0,T},PlotRange->All], ListPlot[data,PlotStyle->Directive[PointSize[Medium],Red]]] the link on the .nb file http://www.4shared.com/folder/249TSjlz/_online.html

  • Lithium: Run filter after find() to format output

    - by Housni
    I wanted to specify the output of a field from within my model so I added a date key to my $_schema: models/Tags.php <?php protected $_schema = array( 'id' => array('type' => 'integer', 'key' => 'primary'), 'title' => array('type' => 'string'), 'created' => array('type' => 'integer', 'date' => 'F jS, Y - g:i a'), 'modified' => array('type' => 'integer') ); ?> I store my time as an unsigned integer in the db (output of time()). I want my base model to format any field that has the date key for output. I thought the best place to do that would be right after a find: extensions/data/Model.php <?php static::applyFilter('find', function($self, $params, $chain) { $schema = $self::schema(); $entity = $chain->next($self, $params, $chain); foreach ($schema as $field => $options) { if (array_key_exists('date', $options)) { //format as a date $params['data'][$field] = $entity->formatDate($field, $options['date']); } } return $entity; }); public function formatdate($entity, $field, $format, $timezone = 'Asia/Colombo') { $dt = new \DateTime(); $tz = new \DateTimeZone($timezone); $dt->setTimestamp($entity->$field); $dt->setTimezone($tz); return $dt->format($format); } ?> This doesn't seem to be working. When I execute a find all, this filter seems to get hit twice. The first time, $entity contains a count() of the results and only on the second hit does it contain the Records object. What am I doing wrong? How do I alter this so that simply doing <?= $tag->created; ?> in my view will format the date the way I want? This, essentially, needs to be an 'after filter', of sorts. EDIT If I can find a way to access the current model entity object (not the full namespaced path, $self contains that), I can probably solve my problem.

  • Appending a TR to Table Not Formatting Correctly

    - by TimNguyenBSM
    My PHP script is sending back an array: $currentStatus = ( isset( $status ) ) ? "1" : "0"; $html = "<tr><td>" . $email . "</td><td>" . ( ( $status->type == 0 ) ? "View Only" : ( ( $status->type == 1 ) ? "View & Mark" : "View, Mark & Edit" ) ) . "</td><td>Invited</td></tr>"; echo json_encode( array( $html, $currentStatus ) ); Then my jquery is appending this to the table: ... success: function( result ) { var resultArray = eval( result ); $( "#myTable tr:last").append( resultArray[0] ); ... } Problem is, when it prints, it prints the following extra marks: [email protected]<\/td> View Only<\/td> Invited<\/td><\/tr>","1"] If I only echo the HTML it appends to table just fine, but I cant do that because I need the $currentStatus back too to do something with it. Thanks!

  • Django: select_related and GenericRelation

    - by Parand
    Does select_related work for GenericRelation relations, or is there a reasonable alternative? At the moment Django's doing individual sql calls for each item in my queryset, and I'd like to avoid that using something like select_related. class Claim(models.Model): proof = generic.GenericRelation(Proof) class Proof(models.Model): content_type = models.ForeignKey(ContentType) object_id = models.PositiveIntegerField() content_object = generic.GenericForeignKey('content_type', 'object_id') I'm selecting a bunch of Claims, and I'd like the related Proofs to be pulled in instead of queried individually.

  • CakePHP – 2 controllers, 1 form

    - by user1327
    I need to create a review form. I have 2 models and 2 controllers – Products and Reviews with 'Products' hasMany 'Reviews' relationship, the review form will be displayed on the current product page (Products controller, 'view' action), and this form will be use another controller (Reviews). Also I need validation with validation errors being displayed for this form. In my Products controller view.ctp I have: // product page stuff... echo $this->Form->create($model = 'Review', array('url' => '/reviews/add')); echo $this->Form->input('name', array('label' => 'Your name:')); echo $this->Form->input('email', array('label' => 'Your e-mail:')); echo $this->Form->input('message', array('rows' => '6', 'label' => 'Your message:')); echo $this->Form->end('Send'); echo $this->Session->flash(); ReviewsController - add: public function add() { if ($this->request->is('post')) { $this->Review->save($this->request->data); $this->redirect(array('controller' => 'products', 'action' => 'view', $this->request->data['Review']['product_id'], '#' => 'reviews')); } } Somehow this horrible code works.. in part. Review saves, but I don't get validation errors, and I can't add 'if ($this->Review->save($this->request->data);) { //... } because it will break this action (missed view error). My question is how to properly deal with this situation to achieve functionality that I need? Should I use elements with request action or I should move adding reviews to the ProductsController?

    I have the following class class Identity < OmniAuth:: Identity:: Models:: ActiveRecord attr_accessible :email, :name, :password_digest, :password, :password_confirmation end I wonder if the above properties are the only ones allowed for a class that derive from a OmniAuth. I wish I could add some more like FirstName, LastName, age, gender, and so on. Do I need to create an other model for those properties or can I just add them to the Identity model? Thanks for helping.

  • long startup time...Need help

    - by Jeff
    My app is all done and working great. So now I ran it on a old iPhone and the app takes 17.3 seconds to start!?!? i spent a lot of time looking into it and i found that the reason it is taking so long to load is i have a lot of views and each view has a png background image. All my views and made in IB and in my code: #import "MyTestAppDelegate.h" #import "MyTestViewController.h" @implementation MyTestAppDelegate @synthesize window; @synthesize viewController; - (void)applicationDidFinishLaunching:(UIApplication *)application { // Override point for customization after app launch [window addSubview:viewController.view]; [window makeKeyAndVisible]; } - (void)dealloc { [viewController release]; [window release]; [super dealloc]; } @end At the end of the code where is says: [window addSubview:viewController.view]; the app seems to be loading all the views in the nib at the same time. All the png's from all the views are about 12mb. There is no need for the app to load all the views at the same time during startup. Is there a way i can only load the first "home" view at startup? (All the views are part of the same nib.)

  • Object Oriented vs Relational Databases

    - by Dan
    Objects oriented databases seem like a really cool idea to me, no need to worry about mapping your domain model to your database model, no messing around with sql or ORM tools. The way I understand it, relational DBs offer some advantages when there is massive amounts of data, and searching an indexing need to be done. To my mind 99% of websites are not massive, and enterprise issues never need to be thought about, so why arn't OO DBs more widely used?

  • Switching between 2 UINavigationControllers

    - by Smikey
    Hi all, I seem to have a problem switching between 2 UINavigationControllers, i.e. one which controls the main (selection) menu of my application, and the second which controls the main session (i.e. the user can't go back to the selection menu once they're started a new session). The first works just fine, but I get into trouble when trying to load the second. I have a class called GameViewController which contains the second UINavigationController instance. I set this up as usual, linking it as an IBOutlet to the delegate and setting up the NavController in the GameViewController.xib file with its 'Class' property pointing at GameScreenViewController (my main game screen), and its NIB Name property pointing to the GameScreenViewController nib file. I then create a new instance of GameViewController and load it. In IB, the navigation controller looks fine, with its View 'loaded from "GameScreenViewController"', however when the NavigationController is loaded in the game, it actually loads the GameViewController's UIWindow instance (just a blank window). I'm not sure how to make it load the Navigation Controller's view rather than its own window? Also, another quick question. When I load the second navigation controller from the first, which makes more sense to use: [self.view addSubview:gameViewController.view]; or [self presentModalViewController:gameViewController animated:YES]; Thanks for any help, much appreciated :D Michael

  • ViewController Navigating

    - by Kobe.o4
    I have 4 ViewControllers, startViewController as the initial View Controller. This contains my intro. After its finish, it will [self presentViewController:vc animated:YES completion:NULL]; into my menuViewController. startViewController ------> menuViewController ------> C1ViewController \ \ ------> ImportantViewController In my menuViewController are buttons for the two ViewController like the above illustration. Also I presented them in the View with this: [self presentViewController:vc animated:YES completion:NULL]; I return tomenuViewController with this [self dismissModalViewControllerAnimated:YES]; What I wanted is to make the ImportantViewController to be the like the parent view or the mainVIew even if I go to other Views. What I need is when ImportantViewController is presented when I go to either C1ViewController or menuViewController it wont be deallocated, or its content there will still be retained. Is it possible? And How? I don't know much about what parent and child view controllers for so I dont know what to implement in my problem. Thank you. BTW, Im using Storyboard.
