  • Using Jquery UI Tab control in ASP.NET MVC

    - by mike3333
    I am new to jquery and am trying out UI plugins. For some reason this following code does not work, in the sense, it does not render the tabs and it's just a bunch of text. But when I copy the page source and paste it in the html page, and put it in the views folder, everything looks great, so , I assume all the js paths are good. Any ideas? <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> Details $(document).ready(function() { $("#tabs").tabs(); }); <div id="tabs"> <ul> <li><a href="#tabs-1">Text 1</a></li> <li><a href="#tabs-2">Text 2</a></li> <li><a href="#tabs-3">Text 3</a></li> </ul> <div id="tabs-1"> <div>tab1 content - adsfadfadsf</div> </div> <div id="tabs-2"> <div>tab 2 content -adfadfadf </div> </div> <div id="tabs-3"> <div>tab 3 content -adfadfadfadf</div> </div> </div> </div>

  • pulling an UIImage from a UITextView or UILabel gives white image

    - by user293139
    Hello all, I need to grab an UIImage from a UITextView or UILabel. I've got a method that will pull an image successfully from other types of views ( [UIViewController view], MKMapView, UIButtons) but I am just getting a white rect for my UITextView. I've been banging my head against the wall for a while and suspect something really, really basic. many thanks! @interface TaskAccomplishmentViewController : UIViewController { MKMapView *mapView; UILabel *timeLeftText; UITextView *challengeText; UIButton *successButton; -(void) setChallangeImageToImageFromChallenge { // works // [currChallenge setChallengeImage:[UIImageUtils grabImageFromView:mapView]]; // [currChallenge setChallengeImage:[UIImageUtils grabImageFromView:[self view]]]; // [currChallenge setChallengeImage:[UIImageUtils grabImageFromView:successButton]]; //doesn't work // [currChallenge setChallengeImage:[UIImageUtils grabImageFromView:timeLeftText]]; [currChallenge setChallengeImage:[UIImageUtils grabImageFromView:challengeText]]; } and the grabImage from a UIView code +(UIImage *)grabImageFromView: (UIView *) viewToGrab { UIGraphicsBeginImageContext(viewToGrab.bounds.size); [[viewToGrab layer] renderInContext:UIGraphicsGetCurrentContext()]; UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); return viewImage; }

  • ASP.NET MVC - Parent-Child Table Relation - how to creat Children in MVC (example request)

    - by adudley
    Hi All. In a standard setup of Parent Child relation, lets say Project and Task. Where a Project is made up of lots of Tasks. So in a standard RDB, we have a Project (ID, Name, Deadline) Task (ID, FK_To_Project, Name, Description, isCompleted) this is all very straight forward. We have an MVC View that views Projects, so we get a nice list of all the project Names next to each deadline. Now we want to CREATE a new PROJECT. The Edit view opens, we type a name, say, 'Make a cup of Tea', with tomorrow as the deadline! Still in this view/web page, I would like a list of all the Child Tasks, in a standard list, with Edit, Delete, and a Create/Add Task button too, just below the 'parent table' details. The simplest way to describe this, is the Parents Table Create/Edit view, with the Childes List View Below it. 1) The ideal solution will also allow my Child Table (Tasks) to have Children also (for more complex scenarios) , and so on, and on, and on. 2) If I navigate away from my Created Project, I don’t want all sorts of random stuff laying around, they went away, it’s gone! 3) I’d expect all the same functionality when Editing an existing project. I’m struggling with the ‘Add New Child’, I had a model dialog (jquery) and all was well, but now when editing an existing child/task, I need to populate the Child Edit, which is a pain and will need loads of java script I think :( How can this be achieved in MVC, does anybody have any examples?

  • How can I encrypt CoreData contents on an iPhone

    - by James A. Rosen
    I have some information I'd like to store statically encrypted on an iPhone application. I'm new to iPhone development, some I'm not terribly familiar with CoreData and how it integrates with the views. I have the data as JSON, though I can easily put it into a SQLITE3 database or any other backing data format. I'll take whatever is easiest (a) to encrypt and (b) to integrate with the iPhone view layer. The user will need to enter the password to decrypt the data each time the app is launched. The purpose of the encryption is to keep the data from being accessible if the user loses the phone. For speed reasons, I would prefer to encrypt and decrypt the entire file at once rather than encrypting each individual field in each row of the database. Note: this isn't the same idea as Question 929744, in which the purpose is to keep the user from messing with or seeing the data. The data should be perfectly transparent when in use. Also note: I'm willing to use SQLCipher to store the data, but would prefer to use things that already exist on the iPhone/CoreData framework rather than go through the lengthy build/integration process involved.

  • Castle Windsor with ASP.NET MVC 2 Areas

    - by Doug Shontz
    Been lurking for a few months and decided to jump in with a question. I am very new to Windsor and IoC in general. I can get Windsor to work with my MVC2 project with no problem. The project I am working on is a "portal" of multiple applications under one MVC2 project using the new Areas concept. In this scenario, each Area will actually be a separate application inside the "portal". We are doing this to effectively share a LOT of common code, views, authentication, and cross-application functionality. Many of our apps link to one another, so it made sense after discussing it to combine them into one project. What I am wondering how to do is actually allow different Areas to inject different concrete classes? In my limited understanding, the Application_Start is governing building the container and assigning it as the controller factory. I don't necessarily want to do all the injection at the application level. We have a config system where we have a config.xml at the root of every Area and those settings override any root settings. I would like to continue that trend by having the injections for each Area be read by the Area's config.xml (an inheritance similar to Webforms web.config where the config in a lower folder overrides settings in a parent folder). Example: I would have an ILogHandler which would need a different concrete implementation depending on which Area of the application I am in. So I would need to inject something different depending on where I am at in the application. I can easily do this using factories since each area could have it's own set of factories, but I am attempting to take this opportunity to learn about IoC and what the benefits/drawbacks are. Any help would be appreciated.

  • UITouch Event Propagation To Background UIViews

    - by drewww
    I'm having troubles getting any UIView that's not the foreground UIView to receive UITouch events. I'm building an all-Core Graphics-app, so I'm not using any built in UIViews or IB or anything - everything is programmatically constructed and drawn into. Here's my view hierarchy: Root View Type A Container Type A View Type A View Type A View Type B Container Type B View Type B View Type B View The containers are just vanilla UIView objects that I create programmatically and add instances of Type A and B to when they're created. I did this originally to make hitTesting easier—Type A objects can be drag-and-dropped onto Type B objects. Type A objects receive touch events fine, but Type B objects (which are contained by Type B Container which is behind Type A Container) don't receive touch events. Both containers occupy the entire screen; they're basically just convenience containers. If I pull Type B Container to the front (eg [self.view bringSubviewToFront:Type B Container]) it receives events properly, but then the Type A Container doesn't get events. How do I propagate events from the view that's on top? Both views occupy the entire screen, so it makes sense that the top-most view is catching the events, but how should I get it to pass those events on to Type B Container? I could inject some code in the container that passes the touch events back to the main ViewController which can pass them on to Type B Container but that feels really messy to me. Is there a nicer way to not have the Type A Container stop propagation? What's the best practice here?

  • Extra white space, on HTML output, on PHP MVC

    - by user316841
    Hi, I'm getting extra white space, that is not CSS, or nothing like it on the view output: The HTML. I've checked for ? (removed, where I could), saved UTF8 without BOM. Checked for existent white space in the beginning of each file, even at end. This is the structure: index.php - this is the entry point; MODEL/ CONTROLLER/ VIEW/ Let's say, that trough method GET, its sent the var TPL with some value. Let's call it LIST, so it pulls the LIST model, with all data and then show the right template to the user, with the right data. I used and tested, with require_once, include_once, include, even tested with readfile (just to test). The LIST Template opens the header.tpl and footer.tpl; I also tryed to remove this both includes from LIST template, but still, the extra white space continued. This is where the extra white space is coming from. This controller is placed between controller activity runs here , this is where the extra white space is coming from: $model_works-getRows(); $rows = $model_works-rows; if ( !require_once('views/list_works.tpl.php') ) { echo "Error."; } // end if clause The list_works.tpl.php, is basicly HTML with tags; I've t tested by changing the extension to something else, like html. Also, just to remember that at top of this file, we are using require_once to open the header.tpl and at bottom the footer.tpl. I've tested by removing both and the extra white space was still generated. The extra white space is being generated here: EXTRA WHITE SPACE HERE Thanks a lot for looking, ;D

  • Wpf Mvvm ComboBox

    - by 2Fast4YouBR
    Hi All, I am new in the Wpf world, so I created a couple of views and all of them have at least one ComboBox, as I am using the MvvM pattern, I get my self re-typing all the time the same line of codes to fill the Combo and to get the SelectedItem (creating properties, privates for fill and other to get). Is there some kind of framework that can improve this part ? or hack/trick ??? as I see too much repetitive code... maybe I am doing something wrong, take a look: XAML: <ComboBox name= "cbDepartments" DisplayMemberPath="DepartmentName" SelectedValuePath ="PrimaryKey" ItemsSource="{Binding Path=Departments}" SelectedItem="{Binding Path=DefaultBranch,Mode=TwoWay}" > ViewModel: private Department defaultBranch; public Department DefaultBranch { get { return this.defaultBranch; } set { if (this.defaultBranch != value) { this.defaultBranch = value; this.OnPropertyChanged("DefaultBranch"); this.saveChangeCommand.RaiseCanExecuteChanged(); this.UserMessage = string.Empty; } } } private ObservableCollection<Department> departments; public ObservableCollection<Department> Departments { get { return this.departments; } set { if (this. departments!= value) { this. departments = value; this.OnPropertyChanged("Departments"); } } }

  • Opening a View with a Table without a NavigationController

    - by Ken
    Hiya, I'm pretty new to developing with Cocoa Touch/XCode and I came across a problem. I'm making a sort of RSS reader for a newssite and I have 5 views of tables navigated with 5 tabs in a TabBarController. If someone selects a newsitem I want another view to open showing the complete newsitem. My problem is that it won't work. This is my code: - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection(NSInteger)section{ return [[[self rssParser]rssItems]count]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{ UITableViewCell * cell = [tableView dequeueReusableCellWithIdentifier:@"rssItemCell"]; if(nil == cell){ cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"rssItemCell"]autorelease]; } cell.textLabel.text = [[[[self rssParser]rssItems]objectAtIndex:indexPath.row]title]; cell.detailTextLabel.text = [[[[self rssParser]rssItems]objectAtIndex:indexPath.row]description]; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; return cell; } - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { [[self appDelegate] setCurrentlySelectedBlogItem:[[[self rssParser]rssItems]objectAtIndex:indexPath.row]]; [self.appDelegate loadNewsDetails]; } And it calls this method in my delegate: -(void)loadNewsDetails{ [[self rootController]pushViewController:detailController animated:YES]; } Please tell me what I'm doing wrong. BTW I do not want to use a NavigationController, just the tabbar I'm using. Thanks in advance, Ken

  • Best practice for structuring a new large ASP.NET MVC2 plus EF4 VS2010 solution?

    - by Nick
    Hi, we are building a new web application using Microsoft ASP.NET MVC2 and Entity Framework 4. Although I am sure there is not one right answer to my question, we are struggling to agree a VS2010 solution structure. The application will use SQL Server 2008 with a possible future Azure cloud version. We are using EF4 with T4 POCOs (model-first) and accessing a number of third-party web-services. We will also be connecting to a number of external messaging systems. UI is based on standard ASP.NET (MVC) with jQuery. In future we may deliver a Silverlight/WPF version - as well as mobile. So put simply, we start with a VS2010 blank solution - then what? I have suggested 4 folders Data (the EF edmx file etc), Domain (entities, repositories), Services (web-services access), Presentation (web ui etc). However under Presentation, creating the ASP.NET MVC2 project obviously creates it's own Models folder etc and it just doesn't seem to fit too well in this proposed structure. I'm also missing a business layer (or does this sit in the domain?). Again I am sure there is no one right way to do it, but I'd really appreciate your views on this. Thanks

  • Mimic CALayer shadow properties found in iPhone OS 3.2 for OS 3.1

    - by niblha
    The CALayer shadow properties like shadowOffset, shadowRadius, shadowColor are not available in iPhone OS versions below 3.2 and I'm wondering how I could mimic that functionality for use with 3.1 and below. I want to use this to be able to add drop shadows to UIViews in a clean way so that the shadows are drawn at layer level somehow, and not by drawing it in a view's -(void)drawRect:(CGRect)rect method which requires to shrink the actual views frame to accomodate for the shadow. (This shrinking approach have been proposed in the other UIView drop shadow related questions I found here on SO). I was thinking a layered approach would be cleaner. For example I tried creating subclassing CALayer to which I added a separate shadow layer as a sublayer, but then that would be drawn on top of whatever was draw in the drawRect: method of the UIView that had the main layer as backing layer. I've also tried implementing the subclass CALayer's drawInContext: something like this, - (void)drawInContext:(CGContextRef)ctx { // code to draw shadow for a frame the size of the layer's frame [super drawInContext:ctx]; } But then the shadow is still clipped to the current clipping bounding box of the context, which seems to be the layers own frame. I also had some idea of redirecting the drawing of the main layer to a sublayer, which would be placed above another sublayer which had the shadow drawn onto it. Then I would probably get rid of the clipping and the shadow would be farthest away. But I couldn't really wrap my head around how I would do that, and it doesn't really feel like a clean approach. Any ideas on how to go about this? Just to make clear how my UIView drop shadow related question is different from the other ones I found here on SO; I do not want to shrink the actual drawing frame of a UIView to accomodate for a shadow. I want it to somehow be on a separate layer in the background, whithout beeing clipped.

  • How Can i reload data in tableview in view controller in iphone

    - by Pugal Devan
    Hi, I am new to iphone development. I have created 5 buttons in the view. On clicking the buttons it navigates to the corresponding views. On clicking the "News" button it navigates and displayed the parsing details in the table view.(This table view, I have created View controller and added table view using Interface Builder and i have set all the properties.) and i go to another button and comes back to the "News" button, every time parsing will happened.How to avoid the multiple parsing when i come back to the button. i have tried this one and my code is, - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; static int i; if(i == 0) { NSString * path = @"http://www.AAAAAAAAAAAAAAAA.com"; [self parseXMLFileAtURL:path]; i++; } [self.newsTable reloadData]; } } Now the parsing is happened only time but the datas are doesnt displayed. My problem is the tableview doesnot reload. newsTable is the instance of the Tableview. How can i achieve this. Please help me out. Thanks.

  • Winforms MVP with Castle Windsor - DI for subforms?

    - by Paul Kirby
    I'm building a winforms app utilizing passive-view MVP and Castle Windsor as an IoC container. I'm still a little new to dependency injection and MVP, so I'm looking for some clarity... I have a main form which contains a number of user controls, and also will bring up other dialogs (ex. Login, options, etc) as needed. My first question is...should I use constructor injection to get the presenters for these other views into the main view, or should I go back to a Service Locator-type pattern? (which I've been told is a big nono!) Or something else? Second question...the user controls need to communicate back to the main form when they are "completed" (definition of that state varies based on the control). Is there a standard way of hooking these up? I was thinking perhaps just wiring up events between the main presenter and the child presenters, but I'm not sure if this is proper thinking. I'd appreciate any help, it seems that the combination of MVP and IoC in winforms isn't exactly well-documented.

  • XAML itemscontrol visibility

    - by Sam
    Hello, I have a ItemsControl in my XAML code. When some trigger occur i want to collapse the full itemsControl, so all the elements. <ItemsControl Name="VideoViewControl" ItemsSource="{Binding Videos}"> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <WrapPanel ItemHeight="120" ItemWidth="160" Name="wrapPanel1"/> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> <ItemsControl.ItemTemplate> <DataTemplate> <views:VideoInMenuView /> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> The trigger: <DataTrigger Value="videos" Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type UserControl}, AncestorLevel=1}, Path=DataContext.VideosEnable}"> <Setter Property="ScrollViewer.Visibility" Value="Visible" TargetName="test1" /> <Setter Property="ScrollViewer.Visibility" Value="Collapsed" TargetName="test2" /> <Setter Property="WrapPanel.Visibility" Value="Collapsed" TargetName="wrapPanel1" /> </DataTrigger> When I add the last setter the program crashes. Without this last setter it works fine but no visibility change.... What is wrong with this code? What is the write method to collapse all the elements of a ItemsControl with a trigger?

  • How to explain to users the advantages of dumb primary key?

    - by Hao
    Primary key attractiveness I have a boss(and also users) that wants primary key to be sophisticated/smart/attractive control number(sort of like Social Security number, or credit card number format) I just padded the primary key(in Views) with zeroes to appease their desire to make the control number sophisticated,smart and attractive. But they wanted it as: first 2 digits as client code, then 4 digits as year year, then last 4 digits as transaction number on that client on a given year, then reset the transaction number of client to 1 when next year flows. Each client's transaction starts with 1. e.g. WM20090001, WM20090002, BB2009001, WM20100001, BB20100001 But as I wanted to make things as simple as possible, I forgo embedding their suggested smartness in primary key, I just keep the primary key auto increments regardless of client and year. But to make it not dull-looking(they really are adamant to make the primary key as smart control number), I made the primary key appears to them smart, on view query, I put the client code and four digit year code on front of the eight-zero padded autoincrement key, i.e. WM200900000001. Sort of slug-like information on autoincremented primary key. Keeping primary key autoincrement regardless of any other information, we are able keep other potential side effects problem when they edit a record, for example, if they made a mistake of entering the transaction on WM, then they edit the client code to BB, if we use smart primary key, the primary keys of WM customer will have gaps in their control number. Or worse yet, instead of letting the control numbers have gaps/holes, the user will request that subsequent records of that gap should shift up to that gap and have their subsequent primary keys re-adjust(decremented). How do you deal with these user requests(reasonable or otherwise)? Do you yield to their request? Or just continue using dumb primary key and explain them the repercussions of having a very smart/sophisticated primary key and educate them the significant advantages of having a dumb primary key? P.S. quotable quote(http://articles.techrepublic.com.com/5100-10878_11-1044961.html): "If you hold your tongue the first time users ask what is for them a reasonable request, things will work a lot better in the end."

Any ideas why the dialog doesnt show up in the first place? Greetz, Steffen

  • shouldAutorotateToInterfaceOrientation won't work!

    Hey. I've been writing my Universal application in portrait mode, and now after about 15 nib files, many many viewCotnrollers, i'd like to implement the shouldAutorotateToInterfaceOrientation and desing some screens in Landscape mode. adding : - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } to ALL of my viewControllers, does not do the work. During Debug, i see that this method is called, but it just won't work! not in the simulator, not in the device, not in Iphone, not in Ipad! i've searched some answers in the forum, and saw some advises to use: - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return (interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight || interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown ); } Didn't worked either, adding: [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications]; and [[UIDevice currentDevice] endGeneratingDeviceOrientationNotifications]; to my viewDidLoad and viewDidUnload respectively didn't worked either. I'm lost.. Any help will do! just one more info... all my Views are of type UIControl, as i needed the TuchUpInside to work. Appriciate your help.

  • Authlogic with nested attributes and polymorphic associations

    - by ferparra
    Hi all! I'm having trouble with the following code: User < AR acts_as_authentic belongs_to :owner, :polymorphic => true end Worker < AR has_one :user, :as => :owner accepts_nested_attributes_for :user end Employer < AR has_one :user, :as => :owner accepts_nested_attributes_for :user end I'd like to create registration forms based on user types, and to include authentication fields such as username and password. I currently do this: UserRegistrationController < AC #i.e. a new Employer def new @employer = Employer.new @employer.build_user end ... end I then include User fields with fields_for. All views render fine, but here's the catch: I cannot build a User, it tells me :password is a wrong method, so I guess the authentication logic was bypassed. What should I do? Am I doing it wrong altogether? Should I drop polymorphic associations in favor of Single Table Inheritance? Whatever I do, I have to make sure it plays nicely with Authlogic.

  • How to use javascript-xpath

    - by Nirmal Patel
    I am using Selenium RC with IE 6 and XPath locators are terribly slow. So I am trying to see if javascript-xpath actually speeds up things. But could not find enough/clear documentation on how to use native x- path libraries. I am doing the following: protected void startSelenium (String testServer, String appName, String testInBrowser){ selenium = new DefaultSelenium("localhost", 4444, "*" +testInBrowser, testServer+ "/"+ appName + "/"); echo("selenium instance created:"+selenium.getClass()); selenium.start(); echo("selenium instance started..." + testServer + "/" + appName +"/"); selenium.runScript("lib/javascript-xpath-latest-cmp.js"); selenium.useXpathLibrary("javascript-xpath"); selenium.allowNativeXpath("true"); } This results in speed improvement of XPath locator but the improvements are not consistent. On some runs the time taken for a locator is halved; while sometimes its randomly high. Am I missing any configuration step here? Would be great if someone who has had success with this could share their views and approach. Thanks, Nirmal

    I’m taking the HelloTabWidget Android example and trying two things: Moving the tabs to the bottom vs. the top (if that’s even desirable from an Android UI POV) Making each tab show a particular WebView in the space above I’ve got this for a layout (high level): <TabHost> <LinearLayout> <FrameLayout> <WebView/> <WebView/> <WebView/> <WebView/> <WebView/> </FrameLayout> <TabWidget/> </LinearLayout> </TabHost> Everything has a width/height set to fill_parent except for the TabWidget which has its layout_height set to wrap_content (and the layout_gravity set to bottom). First thing I noticed is that WebViews don’t show anything until all the parents have width/height set to fill_parent. However, once I do that, they fill the entire display, obscuring the TabWidget. Is there some other trick to making these two views play nicely together?

  • Linq to Entities and POCO foreign key relations mapping (1 to 0..1) problem

    - by brainnovative
    For my ASP.NET MVC 2 application I use Entity Framework 1.0 as my data access layer (repository). But I decided I want to return POCO. For the first time I have encountered a problem when I wanted to get a list of Brands with their optional logos. Here's what I did: public IQueryable<Model.Products.Brand> GetAll() { IQueryable<Model.Products.Brand> brands = from b in EntitiesCtx.Brands.Include("Logo") select new Model.Products.Brand() { BrandId = b.BrandId, Name = b.Name, Description = b.Description, IsActive = b.IsActive, Logo = /*b.Logo != null ? */new Model.Cms.Image() { ImageId = b.Logo.ImageId, Alt = b.Logo.Alt, Url = b.Logo.Url }/* : null*/ }; return brands; } You can see in the comments what I would like to achieve. It worked fine whenever a Brand had a Logo otherwise it through an exception that you can assign null to the non-nullable type int (for Id). My workaround was to use nullable in the POCO class but that's not natural - then I have to check not only if Logo is null in my Service layer or Controllers and Views but mostly for Logo.ImageId.HasValue. It's not justified to have a non null Logo property if the id is null. Can anyone think of a better solution?

  • TabHost NullPointerException in layout

    - by Chubbs
    I been following the Tab example provided by Google. I am trying to use the XML layout provided to setup a tab layout. I use this XML layout @ http://developer.android.com/guide/tutorials/views/hello-tabwidget.html <?xml version="1.0" encoding="utf-8"?> <TabHost xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/tabhost" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TabWidget android:id="@android:id/tabs" android:layout_width="fill_parent" android:layout_height="wrap_content" /> <FrameLayout android:id="@android:id/tabcontent" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:id="@+id/textview1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="this is a tab" /> <TextView android:id="@+id/textview2" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="this is another tab" /> <TextView android:id="@+id/textview3" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="this is a third tab" /> </FrameLayout> </LinearLayout> </TabHost> When ever I switch the Layout tab in the Eclipse layout designer I get a NullPointerException: null error inside my Eclipse. This happens also when I try to drag and drop a TabHost, and then a TabWidget into an empty layout file. What am I doing wrong ? this seems pretty simple.

  • UITableViewController not redrawing new cell text label after popViewControllerAnimated

    - by crunchyt
    I have a problemetic UITableViewController fails to redraw an updated cell after a child view is removed. Here's what's happening. After changing data in a child view, the parent view controller reloads the source data array and runs [tableView reloadData] via a PostNotification. After this triggers, I use popViewControllerAnimated to return to the parent UITableViewController (this pops the child view off the stack, and reveals the controller one level up). However, my updated data does not appear in the parent view controller! According to the debugger, the cell's label has been updated, but the visible label does not change. However, if I scroll-flick the table, momentarily moving the updated cell out of view, when it reappears the label is updated! I also try calling [tableView reloadData] via viewWillAppear but the issue still persists. Here is some additional info that may be helpful. I have a 3 views structured like this: 1/ SettingsViewController : UITableViewController 2/ -- UserView : UITableViewController 3/ ---- UserDetailsView : UIViewController <UIActionSheetDelegate> I am calling UserDetailsView from inside UserView as follows: UserDetailsView *userDetailsView = [[UserDetailsView alloc] init]; [self.navigationController pushViewController:userDetailsView animated:YES]; If I return to the top-most controller (SettingsViewController) and then load the problematic controller (UserView), everything is drawn correctly. It is only when returning from a child view that this issue occurs. Thank you in advance for your suggestions.
