    - by Chris
    Jmeter is not extracting correctly the value with the reg ex. When I play with this reg ex (NAME="token" \s value="([^"]+?)") in reg ex coach with the following html everything work fine but when adding the reg with a reg ex extrator to the request he doesn't found the value even if it's the same html in output. <HTML>< script type="text/javascript" > function dostuff(no, applicationID) { submitAction('APPS_NAME' , 'noSelected=' + no + '&applicationID=' + applicationID); }< /script> <FORM NAME="baseForm" ACTION="" METHOD="POST"> <input type="hidden" NAME="token" value="fc95985af8aa5143a7b1d4fda6759a74" > <div id="loader" align="center"> <div> <strong style="color: #003366;">Loading...</strong> </div> <img src="images/initial-loader.gif" align="top"/> </div> <BODY ONLOAD="dostuff('69489','test');"> From the reg ex extractor reference name: token Regex: (NAME="token" \s value="([^"]+?)") template : $2$ match no.:1 Default value: wrong-token The request following my the POST of the previous code is returning : POST data: token=wrong-token in the next request in the tree viewer. But when I check a the real request in a proxy the token is there. Note : I tried the reg ex without the bracket and doesn't worked either. Do anybody have a idea whats wrong here ? Why jmeter can't find my token with the reg ex extrator ?

    I am trying to display a tree of categories and subcategories by using dijits with zend framework. Haven't been able to find a good example. This is what I've got: Basically I got the following code as my action: class SubcategoriesController extends Zend_Controller_Action{ ..... public function loadtreeAction() { Zend_Dojo::enableView($this->view); Zend_Layout::getMvcInstance()->disableLayout(); //Creating a sample tree of categories and subcategories $a["cat1"]["id"] = "id1"; $a["cat1"]["name"] = "Category1"; $a["cat1"]["type"] = "category"; $subcat1 = array("id" => "Subcat1","name" => "Subcategory1" , "type" => "subcategory"); $subcat2 = array("id" => "Subcat12","name" => "Subcategory12" , "type" => "subcategory"); $a["cat1"]["children"] = array($subcat1,$subcat2); $treeObj = new Zend_Dojo_Data('id', $a); $treeObj->setLabel('name'); $this->view->tree = $treeObj->toJson(); } .... } And on my view: <?php $this->dojo()->requireModule('dojo.data.ItemFileReadStore'); $this->dojo()->requireModule('dijit.Tree'); $this->dojo()->requireModule('dojo.parser'); ?> <div dojoType="dojo.data.ItemFileReadStore" url="/Subcategories/loadtree" jsId="store"></div> <div dojoType="dijit.tree.ForestStoreModel" jsId="treeModel" store="store" rootId="root" rootLabel="List of Categories" childrenAttrs="children" query="{type:'category'}"></div> <div dojoType="dijit.Tree" model="treeModel" labelAttrs="ListOfCategories"></div> It doesn't even seem to try to load the tree at all.

  • weird problem with load () or live () !!

    - by silversky
    I load a page with load () and then I create dinamically a tag. Then I use live() to bind a click event and fires a function. At the end a call unload (). The problem is that when I load the same page again ( without refresh ) when on click the function will be fired twice. If I exit again (again with unload ()) and load the page again on click will fire 3 times and so on .... A sample of my code is: $('#tab').click(function() { $('#formWrap').load('newPage.php'); }); $('div').after('<p class="ctr" ></p>'); $('p.ctr').live('click', function(e) { if($(e.target).is('[k=lf]')) { console.log ('one'); delete ($this); } else if .... }); function delete () { $.post( 'update.php', data); } I have other $.post inside on this page and also on the above live fnc and all work well. The above one also works but like I said on the second load will fire twice and the 3 times and so on ... The weird part for me is that if replece the console with console.log ('two'); save the page and load the page without refresh it will fire on a different rows - one two - if I unload the page replace the console with console.log ('three'); and load again will fire one two and three. I try to use: $.ajax({ url: 'updateDB.php', data: data, type: 'POST', cache:false }); $.ajaxSetup ({ cache: false }); header("Cache-Control: no-cache"); none of this it's working. And I have this problem only on this fnc. What do you think, it could be the reason, it remembers it remembers the previous action and it fires again?

  • How can I read the properties of an object that I assign to the Session in ASP.NET MVC?

    - by quakkels
    Hey all, I'm trying my hand at creating a session which stores member information which the application can use to reveal certain navigation and allow access to certain pages and member role specific functionality. I've been able to assign my MemberLoggedIn object to the session in this way: //code excerpt start... MemberLoggedIn loggedIn = new MemberLoggedIn(); if (computedHash == member.Hash) { loggedIn.ID = member.ID; loggedIn.Username = member.Username; loggedIn.Email = member.Email; loggedIn.Superuser = member.Superuser; loggedIn.Active = member.Active; Session["loggedIn"] = loggedIn; } else if (ModelState.IsValid) { ModelState.AddModelError("Password", "Incorrect Username or Password."); } return View(); That works great. I then can send the properties of Session["loggedIn"] to the View in this way: [ChildActionOnly] public ActionResult Login() { if (Session["loggedIn"] != null) ViewData.Model = Session["loggedIn"]; else ViewData.Model = null; return PartialView(); } In the Partial View I can reference the session data by using Model.Username or Model.Superuser. However, it doesn't seem to work that way in the controller or in a custom Action Filter. Is there a way to get the equivalent of Session["loggedIn"].Username?

  • How do I add a comment to an image using jQuery

    - by marcamillion
    So I am trying to replicate Facebook's picture tagging functionality, and I have the functionality that onClick, a box is created and there is a comment box. Now the issue is that I want to be able to (without doing any back-end processing) take the input from the input field and add it in some form to the underlying image area that they have selected. I would also like to add a small image to that area, that shows that a comment is there. How do I do that? See the code below for what I have for the comment box: <script type="text/javascript"> $(function() { var tag_box = $("<div>").appendTo("body").css({ "width": "40px", "height":"40px", "border":"4px solid #000000", "position":"absolute", "display":"none", "padding":"15px" }); var comment_box = $("<form action='#'><input id='comment' type='text' name='comment' placeholder='Add comment'></form>").appendTo(tag_box).css({"position":"absolute"}); $("#image-wrapper").live('click', function(e){ tag_box.css({ "left": e.pageX - 40, "top": e.pageY - 40, "display": "block" }) .after(comment_box.css({ "left": e.pageX - 65, "top": e.pageY + 40 })); }); }); </script> Now...whenever the user presses enter, the info in the comment box is appended to the URL like so: .html?comment=comment value# Thanks

  • Algorithm to detect how many words typed, also multi sentence support (Java)

    - by Alex Cheng
    Hello all. Problem: I have to design an algorithm, which does the following for me: Say that I have a line (e.g.) alert tcp 192.168.1.1 (caret is currently here) The algorithm should process this line, and return a value of 4. I coded something for it, I know it's sloppy, but it works, partly. private int counter = 0; public void determineRuleActionRegion(String str, int index) { if (str.length() == 0 || str.indexOf(" ") == -1) { triggerSuggestionList(1); return; } //remove duplicate space, spaces in front and back before searching int num = str.trim().replaceAll(" +", " ").indexOf(" ", index); //Check for occurances of spaces, recursively if (num == -1) { //if there is no space //no need to check if it's 0 times it will assign to 1 triggerSuggestionList(counter + 1); counter = 0; return; //set to rule action } else { //there is a space counter++; determineRuleActionRegion(str, num + 1); } } //end of determineactionRegion() So basically I find for the space and determine the region (number of words typed). However, I want it to change upon the user pressing space bar <space character>. How may I go around with the current code? Or better yet, how would one suggest me to do it the correct way? I'm figuring out on BreakIterator for this case... To add to that, I believe my algorithm won't work for multi sentences. How should I address this problem as well. -- The source of String str is acquired from textPane.getText(0, pos + 1);, the JTextPane. Thanks in advance. Do let me know if my question is still not specific enough.

  • Getting an "i" from GEvent

    - by Cosizzle
    Hello, I'm trying to add an event listener to each icon on the map when it's pressed. I'm storing the information in the database and the value that I'm wanting to retrive is "i" however when I output "i", I get it's last value which is 5 (there are 6 objects being drawn onto the map) Below is the code, what would be the best way to get the value of i, and not the object itself. var drawLotLoc = function(id) { var lotLoc = new GIcon(G_DEFAULT_ICON); // create icon object lotLoc.image = url+"images/markers/lotLocation.gif"; // set the icon image lotLoc.shadow = ""; // no shadow lotLoc.iconSize = new GSize(24, 24); // set the size var markerOptions = { icon: lotLoc }; $.post(opts.postScript, {action: 'drawlotLoc', id: id}, function(data) { var markers = new Array(); // lotLoc[x].description // lotLoc[x].lat // lotLoc[x].lng // lotLoc[x].nighbourhood // lotLoc[x].lot var lotLoc = $.evalJSON(data); for(var i=0; i<lotLoc.length; i++) { var spLat = parseFloat(lotLoc[i].lat); var spLng = parseFloat(lotLoc[i].lng); var latlng = new GLatLng(spLat, spLng) markers[i] = new GMarker(latlng, markerOptions); myMap.addOverlay(markers[i]); GEvent.addListener(markers[i], "click", function() { console.log(i); // returning 5 in all cases. // I _need_ this to be unique to the object being clicked. console.log(this); }); } });

  • jQuery code working in Safari and Chrome but not Firefox

    - by Chris Armstrong
    I'm got a site that has a long list of tweets, and as you scroll down the right column follows you down, showing stats on the tweets. (See it in action at http://www.grapevinegame.com . Click 'memorise', then 'skip' to get to the list page. Works in Safari and Chrome). I'm using jQuery to update the top-margin of the right column, increasing it as I scroll down. It seems to be working fine in webkit-based browsers, but doesn't budge in Firefox. Heres the code, the right column element is a div with id = "distance". // Listen for scroll function $(window).scroll(function () { // Calculating the position of the scrollbar var doc = $("body"), scrollPosition = $("body").scrollTop(), pageSize = $("body").height(), windowSize = $(window).height(), fullScroll = (pageSize) - windowSize; percentageScrolled = (scrollPosition / fullScroll); var entries = $("#whispers-list > li").length; // Set position of distance counter $('div#distance').css('margin-top', ($("#whispers-list").height()+$("#latest-whisper").height()+33)*percentageScrolled); // Update distance counter $('#distance-travelled').text(Math.round(distanceTravelled*(1-percentageScrolled))); $('#whispers-list li').each(function(index) { //highlight adjacent whispers if ($('#whispers-list li:nth-child('+(index+1)+')').offset().top >= $('#distance').offset().top && $('#whispers-list li:nth-child('+(index+1)+')').offset().top <= $('#distance').offset().top + $('#distance').height()) { // alert("yup"); $('#whispers-list li:nth-child('+(index+1)+') ul').fadeTo(1, 1); } else { $('#whispers-list li:nth-child('+(index+1)+') ul').fadeTo(1, 0.5); } }); }); Appreciate any help or advice!

  • Can I ignore a SIGFPE resulting from division by zero?

    - by Mikeage
    I have a program which deliberately performs a divide by zero (and stores the result in a volatile variable) in order to halt in certain circumstances. However, I'd like to be able to disable this halting, without changing the macro that performs the division by zero. Is there any way to ignore it? I've tried using #include <signal.h> ... int main(void) { signal(SIGFPE, SIG_IGN); ... } but it still dies with the message "Floating point exception (core dumped)". I don't actually use the value, so I don't really care what's assigned to the variable; 0, random, undefined... EDIT: I know this is not the most portable, but it's intended for an embedded device which runs on many different OSes. The default halt action is to divide by zero; other platforms require different tricks to force a watchdog induced reboot (such as an infinite loop with interrupts disabled). For a PC (linux) test environment, I wanted to disable the halt on division by zero without relying on things like assert.

  • Adding Unlimited Form Fields With JQuery Problem.

  • NSMenu doesn't start tracking

    - by Measunny
    Hey, I have a little cocoa app which usually operates in the background (as agent). Sometimes I'd like to be able to popup a contextmenu (no window or s.th. visible at this time). As I'm only targetting Snow Leopard I tried this: if (windows) { NSMenu *theMenu = [[[NSMenu alloc] initWithTitle:@"test"] autorelease]; [theMenu setShowsStateColumn:NO]; [theMenu setAutoenablesItems:NO]; for (id item in windows) { NSString *labelText = @"some text"; NSMenuItem *theMenuItem = [[[NSMenuItem alloc] initWithTitle:labelText action:@selector(menuItemSelected:) keyEquivalent:@""] autorelease]; [theMenuItem setTarget:self]; [theMenuItem setRepresentedObject:item]; [theMenuItem setEnabled:YES]; [theMenuItem setImage:icon]; [theMenu addItem:theMenuItem]; } [theMenu popUpMenuPositioningItem:nil atLocation:[NSEvent mouseLocation] inView:nil]; } The menu popsup perfectly but if I hover the items with the mouse cursor they don't highlight and I can't click them. The menuItemSelected: method looks just like this: -(IBAction)menuItemSelected:(id)sender { } Any idea what I'm doing wrong?

  • Is it possible to write an IIS URL Rewrite Rule that examines content of HTTP Post?

    - by JohnRudolfLewis
    I need to split a portion of functionality away from a legacy ISAPI dll onto another solution (ASP.NET MVC most likely). IIS7's URL Rewrite sounded like a perfect candidate for the job, but it turns out I cannot find a way to configure the rules the way I need. I need to write a rule that examines the content of the HTTP post for a particular value. i.e. <form method="post" action="legacy_isapi.dll"> <input name="foo" /> </form> if (Request.Form["foo"] == "bar") Context.RewritePath("/some_other_url/on_the_same_machine/foo/bar"); As a proof of concept, I was able to create an IHttpModule that examines context.Request.Form collection and performs a rewrite when certain parameters are present. I installed this module in my website, and it works. Rather than a custom module, however, I'd rather extend the existing URL Rewrite module to support examining the content of the HTTP Post as one of its rules. Is this possible?

  • How to implement menuitems that depend on current selection in WPF MVVM explorer-like application

    - by Doug
    I am new to WPF and MVVM, and I am working on an application utilizing both. The application is similar to windows explorer, so consider an app with a main window with menu (ShellViewModel), a tree control (TreeViewModel), and a list control (ListViewModel). I want to implement menu items such as Edit - Delete, which deletes the currently selected item (which may be in the tree or in the list). I am using Josh Smith's RelayCommand, and binding the menuitem to a DeleteItemCommand in the ShellViewModel is easy. It seems like implementing the DeleteItemCommand, however, requires some fairly tight coupling between the ShellViewModel and the two child view models (TreeViewModel and ListViewModel) to keep track of the focus/selection and direct the action to the proper child for implementation. That seems wrong to me, and makes me think I'm missing something. Writing a focus manager and/or selection manager to do the bookkeeping does not seem too hard, and could be done without coupling the classes together. The windowing system is already keeping track of which view has the focus, and it seems like I'd be duplicating code. What I'm not sure about is how I would route the command from the ShellViewModel down to either the ListViewModel or the TreeViewModel to do the actual work without making a mess of the code. Some day, the application will be extended to include more than two children, and I want the shell to be as ignorant of the children as possible to make that extension as painless as possible. Looking at some sample WPF/MVVM applications (Karl Shifflett's CipherText, Josh Smith's MVVM Demo, etc.), I haven't seen any code that does this (or I didn't understand it). Regardless of whether you think my approach is way off base or I'm just missing a small nuance, please share your thoughts and help me get back on track. Thanks!

  • Email Collector / Implementation

    - by Tian
    I am implementing a simple RoR webpage that collect emails from visitors and store them as objects. I'm using it as a mini-project to try RoR and BDD. I can think of 3 features for Cucumber: 1. User submits a valid email address 2. User submits an existing email address 3. User submits an invalid email My question is, for scenarios 2 and 3, is it better to handle this via the controller? or as methods in a class? Perhaps something that throws errors if an instance is instantiated in sceanrio 2 or 3? Implementation is below, love to hear some code reviews in addition to answers to questions above. Thanks! MODEL: class Contact < ActiveRecord::Base attr_accessor :email end VIEW: <h1>Welcome To My Experiment</h1> <p>Find me in app/views/welcome/index.html.erb</p> <%= flash[:notice] %> <% form_for @contact, :url => {:action => "index"} do |f| %> <%= f.label :email %><br /> <%= f.text_field :email %> <%= submit_tag 'Submit' %> <% end %> CONTROLLER: class WelcomeController < ApplicationController def index @contact = Contact.new unless params[:contact].nil? @contact = Contact.create!(params[:contact]) flash[:notice] = "Thank you for your interest, please check your mailbox for confirmation" end end end

  • Rails 3 get raw post data and write it to tmp file

    - by Andrew
    I'm working on implementing Ajax-Upload for uploading photos in my Rails 3 app. The documentation says: For IE6-8, Opera, older versions of other browsers you get the file as you normally do with regular form-base uploads. For browsers which upload file with progress bar, you will need to get the raw post data and write it to the file. So, how can I receive the raw post data in my controller and write it to a tmp file so my controller can then process it? (In my case the controller is doing some image manipulation and saving to S3.) Some additional info: As I'm configured right now the post is passing these parameters: Parameters: {"authenticity_token"=>"...", "qqfile"=>"IMG_0064.jpg"} ... and the CREATE action looks like this: def create @attachment = Attachment.new @attachment.user = current_user @attachment.file = params[:qqfile] if @attachment.save! respond_to do |format| format.js { render :text => '{"success":true}' } end end end ... but I get this error: ActiveRecord::RecordInvalid (Validation failed: File file name must be set.): app/controllers/attachments_controller.rb:7:in `create'

  • is this uibutton autoreleased ?

    - by dubbeat
    HI This is just a question to check my sanity really. I'm hunting memory leaks that show up in instruments but not the static analyzer. In one spot the analyzer is pointing to this block of code UIButton *randomButton = [UIButton buttonWithType:UIButtonTypeRoundedRect ]; randomButton.frame = CGRectMake(205, 145, 90, 22); // size and position of button [randomButton setTitle:@"Random" forState:UIControlStateNormal]; randomButton.backgroundColor = [UIColor clearColor]; randomButton.adjustsImageWhenHighlighted = YES; [randomButton addTarget:self action:@selector(getrandom:) forControlEvents:UIControlEventTouchUpInside]; [self.view addSubview:randomButton]; For some reason I thought the above code would auto release the button because I'm not calling init or alloc? If I add [randombutton release] at the bottom of the code my button fails to show. Could somebody describe to me the correct way to release a button from memory that is created in the above way? Or would I be better off making the button a class variable and sticking the release in the dealloc method?

I cannot figure out what is wrong, but when i look inside the file (with the cool hexfiend app on macos), 2 things wrong: the header have a wrong value for the biHeight parameter : 4294966216 (hex=C8FBFFFF) the header have a correct biWidth parameter : 1920 the first pixel in the bitmap content (after 54 bytes headers in BMP format) correspond to the upper left corner of the original image. In the original BMP file and as specified in the BMP format, it should be the down left corner pixel first. To explain the full workflow in my app, i have an NSImageView where i can drag a BMP image. This View is bind to an NSImage. After a drag & drop i have an action to save this image (with some text drawing over it) to a BMP file. Here's the code for saving the new BMP file : CGColorSpaceRefcolorSpace = CGColorSpaceCreateWithName(kCGColorSpaceGenericRGB); CGContextRefcontext = CGBitmapContextCreate(NULL, (int)1920, (int)1080, 8, 4*(int)1920, colorSpace, kCGImageAlphaNoneSkipLast); [duneScreenViewdrawBackgroundWithDuneFolder:self inContext:context inRect:NSMakeRect(0,0,1920,1080) needScale:NO]; if(folderType==DXFolderTypeMovie) { [duneScreenViewdrawSynopsisContentWithDuneFolder:self inContext:context inRect:NSMakeRect(0,0,1920,1080) withScale:1.0]; } CGImageRef backgroundImageRef = CGBitmapContextCreateImage(context); NSBitmapImageRep*bitmapBackgroundImageRef = [[NSBitmapImageRepalloc] initWithCGImage:backgroundImageRef]; NSData*data = [destinationBitmap representationUsingType:NSBMPFileType properties:nil]; [data writeToFile:[NSStringstringWithFormat:@"%@/%@", folderPath,backgroundPath] atomically: YES]; The duneScreenViewdrawSynopsisContentWithDuneFolder method uses CGContextDrawImage to draw the image. The duneScreenViewdrawSynopsis method uses CoreText to draw some text in the same context. Do you know what's wrong?

    There is a piece of my program: height = atoi(argv[3]); width = atoi(argv[2]); sprintf(seqName,"%s", argv[1]); // strcpy(seqName, argv[1]); After compiling it, a exe file test is generated, then I use Valgrind to check it. Then I got the following message, however I cannot understand what it tends to tell me. Can anyone provide some kind help, Thanks. 1 contexts (suppressed: 13 from 8) 1 contexts (suppressed: 13 from 8) jl@ubuntu:~/work/dsr_analysis$ valgrind --tool=memcheck --leak-check=yes ./test ==28940== Memcheck, a memory error detector ==28940== Copyright (C) 2002-2009, and GNU GPL'd, by Julian Seward et al. ==28940== Using Valgrind-3.6.0.SVN-Debian and LibVEX; rerun with -h for copyright info ==28940== Command: ./test ==28940== ==28940== Invalid read of size 1 ==28940== at 0x40260CA: strcpy (mc_replace_strmem.c:311) ==28940== by 0x804A5C6: main (me_search.c:1428) ==28940== Address 0x0 is not stack'd, malloc'd or (recently) free'd ==28940== ==28940== ==28940== Process terminating with default action of signal 11 (SIGSEGV) ==28940== Access not within mapped region at address 0x0 ==28940== at 0x40260CA: strcpy (mc_replace_strmem.c:311) ==28940== by 0x804A5C6: main (me_search.c:1428) ==28940== If you believe this happened as a result of a stack ==28940== overflow in your program's main thread (unlikely but ==28940== possible), you can try to increase the size of the ==28940== main thread stack using the --main-stacksize= flag. ==28940== The main thread stack size used in this run was 8388608. ==28940== ==28940== HEAP SUMMARY: ==28940== in use at exit: 0 bytes in 0 blocks ==28940== total heap usage: 0 allocs, 0 frees, 0 bytes allocated ==28940== ==28940== All heap blocks were freed -- no leaks are possible ==28940== ==28940== For counts of detected and suppressed errors, rerun with: -v ==28940== ERROR SUMMARY: 1 errors from 1 contexts (suppressed: 13 from 8)1 contexts (suppressed: 13 from 8) 1 contexts (suppressed: 13 from 8)

  • How to run javascript on an ajax output?

    - by WAC0020
    I am using jquery-ui tabs and ajax to load the content of the tabs. Here is my javascript: $(document).ready(function() { $("#tabs").tabs({ fx: { opacity: 'toggle' } }); $('.hd_item').hover(function() { //Display the caption $(this).find('span.hd_caption').stop(false,true).fadeIn(600); }, function() { //Hide the caption $(this).find('span.hd_caption').stop(false,true).fadeOut(400); }); }); When the user clicks on the tab is will load the content.php via ajax. The output of the ajax is: <li class="hd_item"> <img title="Backyard Brawl" alt="Backyard Brawl" src="games/normal_icons/1844.png" id="hd_icon"> <span class="hd_caption"> <h1>Backyard Brawl</h1> <p id="hd_description">In this game you pick a player and beat each other up with ...</p> <p id="hd_stat">Added: <br>2009-12-14</p><a href="/dirtpilegames/index.php?ground=games&amp;action=play&amp;dig=backyard-brawl">PLAY</a> </span> </li> The problem that I am having is the javascript is not working on the ajax output. How to I get it to work on it?

  • Access a view inside a tab navigator when a tab is clicked

    - by magnus.lassi
    Hi, I I have a view in Flex 3 where I use a tab navigator and a number of views inside the tab navigator. I need to be know which view was clicked because of it's one specific view then I need to take action, i.e. if view with id "secondTab" is clicked then do something. I have set it up to be notified, my problem is that I need to be able to know what view it is. Calling tab.GetChildByName or a similar method seems to only get me back a TabSkin object. <?xml version="1.0" encoding="utf-8"?> <mx:VBox xmlns:mx="http://www.adobe.com/2006/mxml" width="100%" height="100%" xmlns:local="*" creationComplete="onCreationComplete(event)"> <mx:Script> <![CDATA[ import mx.events.FlexEvent; import mx.controls.Button; protected function onCreationComplete(event:Event):void { for(var i:int = 0; i < myTN.getChildren().length; i++) { var tab:Button = myTN.getTabAt(i); tab.addEventListener(FlexEvent.BUTTON_DOWN, tabClickHandler); } } private function tabClickHandler(event:FlexEvent):void { var tab:Button; if(event.currentTarget is Button) { tab = event.currentTarget as Button; // how do I access the actual view hosted in a tab that was clicked? } } ]]> </mx:Script> <mx:TabNavigator id="myTN"> <local:ProductListView id="firstTab" label="First Tab" width="100%" height="100%" /> <local:ProductListView id="secondTab" label="Second Tab" width="100%" height="100%" /> </mx:TabNavigator> </mx:VBox>
