  • How can one cache bust files referenced in a LESS file when using Symfony2, Twig, and Assetic?

    - by user3719083
    I have a web site built on Symfony2 which uses twig templates, LESS, and assetic. In order to cache bust assets, I'm simply using this in my config.yml: framework: templating: engines: ['twig'] assets_version: 'asset-version-here' And then I use the asset() function to load the asset and the cache busting is handled for me. However, the concern I have is when I load my LESS (css) file, there are references to other files, and I would like to know how these files can be cache busted as well. Example: .someSelector { background:url('../images/filename.png'); } How can I make sure that the referenced file, filename.png is cache busted upon deployment? The asset files referenced in Twig using asset() are cache busted automatically upon deployment (I use a deployment script hook that updates the assets_version in the framework's config), but those referenced in a stylesheet are not. How can I do this?

  • flash cs4 file reference. Event.COMPLETE not called on a MAC,

    - by jobbie jones
    Hi, I am working with a fileReference, however I'm having issues running on Safari on a MAC... EDIT The below example also doesnt work on Safari on a MAC... http://www.permadi.com/blog/2010/06/flash-as3-using-filereference-to-load-files-example-for-flash-cs4-and-above/ # The workflow on a PC runs as such: 1) Create file reference 2) attach addEventListener's for Event.SELECT and Event.COMPLETE 3) call the browse() method On a PC, Event.SELECT is fired when a file has been selected. Event.COMPLETE is fired when the file data is available to flash. If I select an 500meg file, it takes a few seconds before Event.COMPLETE is fired. If I attempt to access the file data properties (such as reading the data stream) before Event.COMPLETE is fired, I receive null reference errors... So far so good. However, on a MAC (speficially Safari, not tested other browsers), the Event.COMPLETE is not fired. I have checked the Adobe docs, which say Event.COMPLETE is fired when the upload is completed. So why does it get fired on windows when the fileReference has parsed the file, but the upload method has not yet been called... Can anyone help? Here's snippets of the code I am working on: public function browseFile(target:Object):void { var imagesFilter:FileFilter = new FileFilter("Allowed files", "*.jpg;*.bmp;*.flv;"); fileReference.browse([imagesFilter]); fileReference.addEventListener(Event.SELECT, fileSelect); fileReference.addEventListener(Event.COMPLETE, fileSelectComplete); } private function fileSelect(event:Event):void { // update label - IMPORTANT for large files as there's a delay while flash parses file, before control is handed back to this script... setStatusLabel("...loading file"); var fileReference:FileReference = event.target as FileReference; fileReference.addEventListener(Event.COMPLETE, fileSelectComplete); // load the file into the fileReference object fileReference.load(); } // Called when upload file has been processed by flash (a few secs for large files, or fileRef.data is null...) private function fileSelectComplete(event:Event):void { var fileReference:FileReference=event.target as FileReference; trace("ready to do things - but not fired on Safari on a MAC "); }

  • Post Loading ads from Google Admanager

    - by Prem
    I have changed code around to basically load an add the bottom of the page in a hidden div and attached an onload event handler that called document.getElementById(xxx).appendChild() to take the hidden ad and move it into the right spot in my page. This works GREAT.. however when the ad is a text ad it AFTER i move the ad there is nothing in the rendered Iframe. I did tests to see what it looks like before i move it and sure enough the text links load in the IFRAME but the second i do the appendChild call to move the div that contains the ad i seem to loose the contents of the Iframe. Any ideas whats going on <div id="myad" style="display: none;"> GA_googleFillSlot("MyADSlotName"); </div> <script> window.onload = function() { // leader board document.getElementById('adplaceholder').appendChild(document.getElementById('myAd')); document.getElementById('myAd').style.display = ''; </script

  • Code in Global.asax prevents webpage from loading

    - by pete the pagan-gerbil
    I've made a static class to hold a number of configuration values (and also swap these values out in unit tests). If I initialise it in the Global.asax, the code runs correctly but the page doesn't load at all, and trying to navigate to a specific page fails. I can't initialise the values in a constructor or inline on the field declarations, because I need to be able to swap the values out in unit tests before the web.config is interrogated. Basically, putting the one line "ConfigClass.SetValues()" in the Global.asax prevents the app from loading correctly (although, as I say, it runs the code fine) and removing it again makes the app load properly - but without the class values initialised. As an aside, I'm sure I had this working correctly and being initialised in the Global.asax yesterday. I'm positive I didn't take any action to change or break it... Does anyone have advice on how I might track down what's going on here? Was I mistaken that it worked before (always possible) and that I need to go back and redesign something?

  • VB 2010 Express - Debugger is not breaking on errors, Sub producing error simply terminates

    - by hamlin11
    I'm using VB 2010 Express. When an error occurs in the form load function, the form load function simply terminates. Then, when I click on one of my buttons, the button click sub also terminates if it has an error. I can wrap the code that produces the errors in try/catch blocks, but I'd very much rather the debugger to throw an immediate break point (like usual) or at least exit the program. It's making it very difficult to program, not knowing whether or not previous Subs executed fully. Any thoughts on what might be going on? Thanks

  • Application Runs when Debugging but not when Published.

    - by corymathews
    When publishing my web application and then running it will return the error "Could not load file or assembly 'BaseApplicationName' or one of its dependencies. An attempt was made to load a program with an incorrect format." However if I run the application through debugging (f5) it runs correctly. I guess what it comes down to is what differences are there when running an application through debugging vs publishing it that would cause a problem like this? When publising I have it set to delete all existing. History of how it started... I added the 32 bit Oracle.DataAccess dll to my 64 bit system. It would not work and crash giving the same error as above but with the Oracle.DataAccess name instead of the baseApplicationName. I have since removed all references to it and removed the dll to try and get it to run without it once again. Any advice?

  • Can't get results from a IQueryable.

    - by StackPointer
    Hi! I have the following code in Linq to Entity: var policy= from pol in conn.Policy where pol.Product.DESCRIPTION=="someProduct" SELECT pol; Then, the table Policy, has some dependencies for a table called Entity. If I do this: foreach(Policy p in policy){ if(!p.Entity.IsLoaded) p.Entity.Load(); IEnumerable<Entity> entities= from ent in p.Entity Where ent.EntityType.DESCRIPTION=="SomeEntityType" select ent; Console.Writeline(entities.ElementAt(0).NAME); } It says, "Object not set to an instance", but if I do: foreach(Policy p in policy){ if(!p.Entity.IsLoaded) p.Entity.Load(); foreach(Entity et in p.Entity)Console.Write(et.NAME); } It works! Can anyone tell me why? Thank you, Best regards.

  • Faster 2D Collision detection

    - by eShredder
    Recently I've been working on a fast-paced 2d shooter and I came across a mighty problem. Collision detection. Sure, it is working, but it is very slow. My goal is: Have lots of enemies on screen and have them to not touch each other. All of the enemies are chasing the player entity. Most of them have the same speed so sooner or later they all end up taking the same space while chasing the player. This really drops the fun factor since, for the player, it looks like you are being chased by one enemy only. To prevent them to take the same space I added a collision detection (a very basic 2D detection, the only method I know of) which is. Enemy class update method Loop through all enemies (continue; if the loop points at this object) If enemy object intersects with this object Push enemy object away from this enemy object This works fine. As long as I only have <200 enemy entities that is. When I get closer to 300-350 enemy entities my frame rate begins to drop heavily. First I thought it was bad rendering so I removed their draw call. This did not help at all so of course I realised it was the update method. The only heavy part in their update method is this each-enemy-loops-through-every-enemy part. When I get closer to 300 enemies the game does a 90000 (300x300) step itteration. My my~ I'm sure there must be another way to aproach this collision detection. Though I have no idea how. The pages I find is about how to actually do the collision between two objects or how to check collision between an object and a tile. I already know those two things. tl;dr? How do I aproach collision detection between LOTS of entities? Quick edit: If it is to any help, I'm using C# XNA.

  • How do I confirm a pdf loaded correctly with Watir webdriver testing

    - by Mike Rose
    This is a general type question that I dont know what code I could post that would help get an answer. So I apologize in advance, but if some piece of code would help, please let me know and Ill add it. The question is, how do I confirm that a pdf loaded in a web browser when using Ruby/Cucumber/Watir Webdriver? My test clicks on a random link that should load a pdf in a new browser window, so I cant check the url because it will vary with each test. Any ideas how I can make sure the correct pdf loads after clicking the link that should load it?

  • Happy Tau Day! (Or: How Some Mathematicians Think We Should Retire Pi) [Video]

    - by Jason Fitzpatrick
    When you were in school you learned all about Pi and its relationship to circles and turn-based geometry. Some mathematicians are rallying for a new lesson, on about Tau. Michael Hartl is a mathematician on a mission, a mission to get people away from using Pi and to start using Tau. His manifesto opens: Welcome to The Tau Manifesto. This manifesto is dedicated to one of the most important numbers in mathematics, perhaps the most important: the circle constant relating the circumference of a circle to its linear dimension. For millennia, the circle has been considered the most perfect of shapes, and the circle constant captures the geometry of the circle in a single number. Of course, the traditional choice of circle constant is p—but, as mathematician Bob Palais notes in his delightful article “p Is Wrong!”,1 p is wrong. It’s time to set things right. Why is Pi wrong? Among the arguments is that Tau is the ration of a circumference to the radius of a circle and defining circles by their radius is more natural and that Pi is a 2-factor number but with Tau everything is based of a single unit–three quarters of a turn around a Tau-defined circle is simply three quarters of a Tau radian. Watch the video above to see the Tau sequence (which begins 6.2831853071…) turned into a musical composition. For more information about Tau hit up the link below to read the manifesto.

  • Applet problem with IPlanet and Firefox (class not found)

    - by JB Hurteaux
    I have an applet which loads nicely when accessed locally (both IE and Firefox). However, when I put my webpage in a webserver (local IPlanet), it refuses to load on Firefox (but still fine on IE). I get the following error in the java console: load: class XXX.localprinting.LocalPrintingApplet.class not found. java.lang.ClassNotFoundException: XXX.localprinting.LocalPrintingApplet.class at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.plugin2.applet.Plugin2ClassLoader.loadCode(Unknown Source) at sun.plugin2.applet.Plugin2Manager.createApplet(Unknown Source) at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Caused by: java.io.IOException: open HTTP connection failed:https://XXX/test/XXX/localprinting/LocalPrintingApplet/class.class at sun.plugin2.applet.Applet2ClassLoader.getBytes(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader.access$000(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) ... 7 more Exception: java.lang.ClassNotFoundException: XXX.localprinting.LocalPrintingApplet.class Any idea what could explain the different behavior in the webserver? I researched the issue of "class not found" already but without finding something relevant.

  • Loading a DB table into nested dictionaries in Python

    - by Hossein
    Hi, I have a table in MySql DB which I want to load it to a dictionary in python. the table columns is as follows: id,url,tag,tagCount tagCount is the number of times that a tag has been repeated for a certain url. So in that case I need a nested dictionary, in other words a dictionary of dictionary, to load this table. Because each url have several tags for which there are different tagCounts.the code that I used is this:( the whole table is about 22,000 records ) cursor.execute( ''' SELECT url,tag,tagCount FROM wtp ''') urlTagCount = cursor.fetchall() d = defaultdict(defaultdict) for url,tag,tagCount in urlTagCount: d[url][tag]=tagCount print d first of all I want to know if this is correct.. and if it is why it takes so much time? Is there any faster solutions? I am loading this table into memory to have fast access to get rid of the hassle of slow database operations, but with this slow speed it has become a bottleneck itself, it is even much slower than DB access. and anyone help? thanks

  • NSUserDefaults and default language used for I18N

    - by fedmest
    I have searched around a lot for this and found some answers that sounded quite like what I wanted but never worked. I simply need to have my iPhone app load NIBs and Localizable.strings that I decide (through user selection) rather than the ones that are established through the global iPhone/iPad settings. General consensus seems to be that this line [[NSUserDefaults standardUserDefaults] setObject:[NSArray arrayWithObject:@"ro"] forKey:@"AppleLanguages"]; would do the trick (in this specific case, load the NIBs and Localizable.strings in ro.lproj) but I have not had such luck. It keeps on looking for the files in en.lproj or whatever language I chose in the Settings app. I have then tried adding this line [[NSUserDefaults standardUserDefaults] setObject:[NSArray arrayWithObject:@"ro_RO"] forKey:@"AppleLocale"]; and to my great surprise, it worked! ...only once :-( then back to the same issue. Has anyone got any idea how to solve this issue? The aforementioned code was added at the very start of applicationDidFinishLaunching, which is before any NIBs or strings files should be loaded.

  • SEO and internal links

    - by hanazair
    I'm fairly new to SEO and although I've read many articles on the topic I still don't have a clear idea of how to get my client's website get to the first page of Google Search. I run MOZ competitor analysis and see that a competitor that comes up at the top of Google Search has approximately same Domain Authority, Domain Moz Rank and Trust. They have 8 External Linking Root Domains while my client's site has five. Yet the competitor comes up as one of the top sites on the first page, and my client's side is on page #3. Then I noticed one drastic difference in competitor's ranking and that is Total Links. He has 1,388! I don't understand how this could be a positive factor in Search Engine ranking and how can they legitimately have 1,388 links (while only 14 of those are external). Another competitor who is #2 in search engine rankings has 773 links total with only 14 external links. It seems fishy, but yet there they are - at the top of the search engine results. Is that some current way to trick Search Engines? What to do if I'd like to get my client's website onto the first page by some legitimate means? Thanks.

  • Flex Air HTMLLoader blank pop up window when flash content is loaded

    - by user128938
    I have a flex Air program that loads external content with the HTMLLoader. Now for some reason whenever I load a page that has any flash content a blank system window pops up outside of my program. It's completely blank, all white with min, max and close buttons. If I close it any flash content I loaded stops working. For the life of my I can't figure out what's happening and there's no messages in the console and no title for the window. Does anyone have any ideas? I appreciate any help you can give. Here's the code I'm using: private var webPage:HTMLLoader; private function registerEvents():void { this.addEventListener(gameLoadEvent.GAME_LOAD, gameLoad); //webPage = new HTMLLoader(); } //function called back from Game Command to load correct game private function gameLoad(event:Event):void { var gameEvent:gameLoadEvent = event as gameLoadEvent; loadgame(gameEvent.url, gameEvent.variables); } private function loadgame(url:String, variableString:String):void { DesktopModelLocator.getInstance().scaleX = 1; DesktopModelLocator.getInstance().scaleY = 1; //var url:String = "http://pro-us.sbt-corp.com/aspx/member/LaunchGame.aspx"; var request:URLRequest = new URLRequest(url); //var variables:URLVariables = new URLVariables("gameNum=17&as=as1&t=demo&package=a&btnQuit=0"); if(variableString != null && variableString != ""){ var variables:URLVariables = new URLVariables(variableString); variables.exampleSessionId = new Date().getTime(); variables.exampleUserLabel = "guest"; request.data = variables; } webPage = HTMLLoader.createRootWindow(true, null, true, null); webPage.height = systemManager.stage.nativeWindow.height - 66; webPage.width = systemManager.stage.nativeWindow.width; webPage.load(request); webPage.navigateInSystemBrowser = false; flexBrowser.addChild(webPage); } ]]> </mx:Script> <mx:HTML id="flexBrowser" width="1366" height="658" backgroundAlpha="0.45" creationComplete="registerEvents();" x="0" y="0"> </mx:HTML>

  • Business knowledge in a large financial org?

    - by Victor
    As a programmer working in the finance industry, I recently got a project that is a hedge fund adminsitrative application(used to calculate NAVs, allocate assets etc.) From a business point of view this is a good thing. When we think of our 'next' project, typically the impulse is to think in terms of technology. e.g: 'I want to work on a project that uses SOA/cloud etc etc.' I am interested to know if anyone while career planning also takes into account the business aspect of a future project. i.e. what the application does. So does anybody ever think like this : 'I wish to work on a trading system so I can understand capital markets better.' instead of 'I want to work on a project that uses SOA/cloud etc etc.' I say this because it appears to me in the finance domain, for senior position, good business knowledge pays well. So maybe a guy that knows more business but maybe not so much latest technologies is at an advantage? The rockstar programmer seems more suited for an aggressive startup. Particularly big old finance orgs rarely invest in tech just for the 'cool factor'. No?

  • Embed external images for use in HTML canvas?

    - by Philipp Lenssen
    I'm using JavaScript to load an image into my Canvas element in Firefox. This works fine for local images, but throws a security exception for external images. Is there any way to avoid this security exception, one that does not involve my server having to act as proxy to load the image locally (because that would stress my server)? PS: The current code is similar to this: var img = new Image(); var contextSource = canvasSource.getContext('2d'); contextSource.drawImage(img, 0, 0); // get image data to do stuff with pixels var imageDataSource = contextSource.getImageData(0, 0, width - 1, height - 1);

  • Rails: unexpected behavior updating a shared instance

    - by Pascal Lindelauf
    I have a User object, that is related to a Post object via two different association paths: Post --(has_many)-- comments --(belongs to)-- writer (of type User) Post --(belongs to)-- writer (of type User) Say the following hold: user1.name == "Bill" post1.comments[1].writer == user1 post1.writer == user1 Now when I retrieve the post1 and its comments from the database and I update post1.comments[1].writer like so: post1.comments[1].writer.name = "John" I would expect post1.writer to equal "John" too. But it doesn't! It still equals "Bill". So there seems to be some caching going on, but the kind I would not expect. I would expect Rails to be clever enough to load exactly one instance of the user with name "Bill"; instead is appears to load two individual ones: one for each association path. Can someone explain how this works exactly and how I am to handle these types of situations the "Rails way"?

  • alternatives to eval for running remote code.

    - by Raynos
    Are there any alternatives to using eval to immediatly run remote & trusted javascript code. function load(filePath) { var o = $.ajax({ url: filePath, dataType: 'html', async: false }); eval(o.responseText); } load("somePath"); // run a function that relies on the code from o.responseText being loaded doSomethingWithCode(); I'm aware that synchronous loading of javascript is adviced againts. But if there is no choice are there any cross browser alternatives for the use of eval above. [Edit] To clarify in more detail the code being loaded is a self executing function. Which needs to execute before doSomethingWidthCode. It's also being loaded from the server on the same domain hence its trusted.

  • How to move the mouse

    - by GroundZero
    I'm making a little bot in C#. At the moment it works pretty well, it can load text from a file and type it for you. But for now, I need to manualy click the textfield to put the focus on it, remaximize my form and then click the Type-button. After the typing, I need to manualy slide the scorebar and press submit. I'd like to know how I can move my mouse with C# and if possible, if possible I'd like to load the mouse positions from a xml-file. I need to move to the textfield, click in it to focus on it, start the type script, move to the slider, hold the mouse down on it while dragging, releasing it on the correct position & clicking on the submitbutton This is what I have for now: To load in the variables, I'm using this script: private void Initialize() { XmlTextReader reader = new XmlTextReader(Application.StartupPath + @"..\..\..\CursorPositions.xml"); while (reader.Read()) { switch (reader.NodeType) { case XmlNodeType.Element: // The node is an element. element = reader.Value; break; case XmlNodeType.Text: //Display the text in each element. switch (element) { case "Textbox-X": textX = int.Parse(reader.Value); break; case "Textbox-Y": textY = int.Parse(reader.Value); break; case "SliderBegin-X": sliderX = int.Parse(reader.Value); break; case "SliderBegin-Y": sliderY = int.Parse(reader.Value); break; case "SubmitButton-X": submitX = int.Parse(reader.Value); break; case "SubmitButton-Y": submitY = int.Parse(reader.Value); break; } break; } } This is the xml-file: <?xml version="1.0" encoding="utf-8" ?> <CursorPositions> <Textbox-X>430</Textbox-X> <Textbox-Y>270</Textbox-Y> <SliderBegin-X>430</SliderBegin-X> <SliderBegin-Y>470</SliderBegin-Y> <SubmitButton-X>860</SubmitButton-X> <SubmitButton-Y>365</SubmitButton-Y> </CursorPositions> To move the mouse I'm using this piece of code: public partial class FrmMain : Form { [System.Runtime.InteropServices.DllImport("user32.dll")] public static extern void mouse_event(int dwFlags, int dx, int dy, int cButtons, int dwExtraInfo); public const int MOUSEEVENTF_LEFTDOWN = 0x0002; public const int MOUSEEVENTF_LEFTUP = 0x0004; public const int MOUSEEVENTF_RIGHTDOWN = 0x0008; public const int MOUSEEVENTF_RIGHTUP = 0x0010; ... private void btnStart_Click(object sender, EventArgs e) { // start button (de)activates loop if (!running) { btnStart.Text = "Stop"; btnStart.Cursor = Cursors.No; running = true; } else { btnStart.Text = "Start"; btnStart.Cursor = Cursors.AppStarting; running = false; } while (running) { // move to textbox & type Cursor.Position = new Point(textX, textY); mouse_event(MOUSEEVENTF_LEFTDOWN, textX, textY, 0, 0); mouse_event(MOUSEEVENTF_LEFTUP, textX, textY, 0, 0); Type(); // wait 90 seconds till slider available Thread.Sleep(90 * 1000); // move to slider & slide according to score Cursor.Position = new Point(sliderX, sliderY); mouse_event(MOUSEEVENTF_LEFTDOWN, sliderX, sliderY, 0, 0); Cursor.Position = new Point(sliderX + 345 / 10 * score, sliderY); mouse_event(MOUSEEVENTF_LEFTUP, sliderX + 345 / 10 * score, sliderY, 0, 0); // submit Cursor.Position = new Point(submitX, submitY); mouse_event(MOUSEEVENTF_LEFTDOWN, submitX, submitY, 0, 0); mouse_event(MOUSEEVENTF_LEFTUP, submitX, submitY, 0, 0); // wait 10 sec to be sure it's submitted Thread.Sleep(10 * 1000); // refresh page SendKeys.SendWait("{F5}"); // get new text NewText(); // wait 10 sec to refresh and load song Thread.Sleep(10 * 1000); } } } PS: I get the coordinates via my form. I've got 2 labels that show my X & Y coordinates. To capture them outside the form, I press and hold my Left Mouse Button and 'drag' it outside the form to the correct place. This way I get the coordinates of my mouse outside the form

  • GMap in iframe gets off-center

    - by Daj pan spokój
    I have a Google Map (API 2) that used to work fine as a standalone page. However, when I load the map page within an iframe (with Thickbox), the map gets off-center: normally it's centered over Germany and in the iframe it centers on Iran, instead. How to make the map center correctly? My guesses: The problem can result from the iframe loading time. I guess, that the script calculates window size basing on the iframe size when it's still loading. It's strange since I load the map when the document is ready. $(document).ready(function() { setupSearchForm(); setupMap(); setupResults(); }); For instance, when I refresh the already loaded iframe the center comes back to Germany. A sample of code loading the map

    I'm creating an installation script for an application that I'm developing and need to create databases dynamically from within PHP. I've got it to create the database but now I need to load in several .sql files.

So, please.. how do I load an sql file from within PHP? (as phpMyAdmin does with it's import command).

  • Exception showing a erroneous web page in a WPF frame

    I have a small application where i need to navigate to an url, I use this method to get the Frame: public override System.Windows.UIElement GetPage(System.Windows.UIElement container) { XmlDocument doc = new XmlDocument(); doc.Load(Location); string webSiteUrl = doc.SelectSingleNode("website").InnerText; Frame newFrame = new Frame(); if (!webSiteUrl.StartsWith("http://")) { webSiteUrl = "http://" + webSiteUrl; } newFrame.Source = new Uri(webSiteUrl); return newFrame; } My problem is now that the page im trying to show generates a error (or so i think), when i load the page in a browser it never fully loads, keeps saying "loading1 element" in the load bar and the green progress line (IE 8) keeps showing. When i attach my debugger i get this error: System.ArgumentException was unhandled Message="Parameter and value pair is not valid. Expected form is parameter=value."

  • Ria Services loading foreign keys with Linq-to-SQL

    - by Stephan
    I have a database that consists of 5 tables : Course, Category, Location, CourseCategories, and CourseLocations. The last 2 tables just contain the two foreign keys. A Course has many-to-many relationships with both category and location. I am trying to load the data into a Silverlight app using Ria Services. My DB model is Linq-to-SQL. I have tried adding the [Include] attribute to the metadata classes and I have added the DataLoadOptions so it should load the all tables when you ask for a Course. However on the client side I am never getting back any entries in the CourseCategories and CourseLocations properties. What else needs to be done to get the foreign key relationships to exist across the serialization.
