  • Unable to pass attribute from controller to view

    - by MDS
    I'm using Spring MVC 3 for a web app. In the app a URI template is supposed to be handled by a controller method, which then passes an attribute to a view. Currently, the controller does handle the request, and it even forwards to the correct view. However, it does NOT pass the attribute to the view. Below are the URI template, controller method and relevent jsp tags. Anyone see what is wrong? URI: /home/{status} Controller: @RequestMapping("/home") @Controller public class HomeController { ... ... @RequestMapping(value="/{status}") public String homeStatusView(@PathVariable("status") String status, ModelMap model) { model.addAttribute("status", status); return "home"; } } JSP: ... <c:if test="${not empty status}"> <span class="status">Your status is available...</span> </c:if> ...

  • Implementing prompts in text-input

    - by AntonAL
    Hi, I have a form with some text-inputs: login, password. If user sees this form the first time, input-texts should "contain" prompts, like "enter login", "enter password". If user clicks text-input, it's prompt should disappear to allow typing. I have seen various examples, that uses background image with prerendered text on it. Those images are appearing with following jQuery: $("form > :text").focus(function(){ // hide image }).blur(function(){ // show image, if text-input is still empty if ( $(this).val() == "" ) // show image with prompt }); This approach has following problems: localization is impossible need to pre-render images for various textual prompts overhead with loading images How do you overcomes such a problems ?

  • Jquery li element id

    - by Gazler
    Hi, I am using a jquery contextmenu plugin for right click menus which I am trying to add to each li element of an unordered list with the ID mailbox. The code I have is: $("#mailbox > li").contextMenu('myMenu1', { bindings: { 'open': function(t) { alert('Trigger was '+t.id+'\nAction was Open'); } //CODE SNIPPED }); My assumption is that this should alert the id of the list element that the contextMenu was called from, however it is returning an empty string. Am I accessing/assigning these correctly? t is an object HTMLLIElement in the context above by the way. Cheers, Gazler.

  • jquery add remove objects

    - by Scarface
    Hey guys quick question, I have an add remove script that will add a unique element and should remove it on a click function but does not. I think it is because the added object is not in the DOM when page is loaded but I am not sure how to fix this. IF anyone has any advice I would greatly appreciate it. $(document).ready(function(){ if (action=='content-change'){ $('#droppable2-inner').empty().append('<div id="content-image"><img id="visual-background2" src=' + src + '></div><div id="drop-content" action="drop-image">x</div>'); } $("#drop-content").click(function() { $('#content-image').remove(); }); })

  • [Resolved] OWC does not work with IE8

    - by mactov
    Hi, I have a web page that is generated with Access 2003 and uses Office Web Components. It worked fine with IE6 and IE7 but does not work anymore with IE8. Here are more details. I create an MSODSC component and a WSH object to get my ConnectionString in the registry. Then the Dropdown Lists are fed by a request to the database. It works perfect with IE6 and IE7, works locally with IE8 but if the page is served by IIS to IE8, the drop down lists are empty. Can anyone help me ? Thanks Mactov It was just a security issue. I had put my site in the confidence zone (according to the error message). I transfered it into intranet zone and it works perfect.

  • Converting C# class to JavaScript

    - by AgileMeansDoAsLittleAsPossible
    Take a look at this basic class: namespace AcmeWeb { public string FirstName { get; set; } public class Person { public Person(string firstName, string lastName) { if (String.IsNullOrEmpty(firstName)) { throw new ArgumentNullException(firstName); } this.FirstName = firstName; } } } What's the best translation of this into JavaScript? This is what I'm thinking: (function(namespace) { namespace.Person = function(firstName, lastName) { // Constructor (function() { if (!firstName) { throw "'firstName' argument cannot be null or empty"; } })(); // Private memberts var _ = { firstName: firstName }; // Public members this.firstName = function(value) { if (typeof(value) === "undefined") { return _.firstName; } else { _.firstName = value; return this; } }; }; })(AcmeWeb);

  • iPhone real memory climbs when interacting with UI

    - by Scott Gress
    I've been using the Activity Monitor to check the memory usage of my iPhone apps. I've noticed that the Real Memory climbs whenever I interact with the UI in any way, even if there's no code being called. For example, I can create a brand new View-Based application and run it, and as I click or drag in the empty window the Real Memory increases even though the app isn't responding in any way. I get that the view controller is doing some stuff in the background to interpret my interactions, but it seems like the memory should go back down after a second or so. Instead, it keeps going up and up and up as long as I keep clicking or dragging. I can wait forever and it never decreases. This is a little disturbing. Am I missing something?

  • C++ Inheritance Question

    - by shaz
    I have a base class MessageHandler and 2 derived classes, MessageHandler_CB and MessageHandler_DQ. The derived classes redefine the handleMessage(...) method. MH_DQ processes a message and puts the result in a deque while MH_CB processes the message and then executes a callback function. The base class has a static callback function that I pass along with a this pointer to a library which calls the static callback when a new message is available for processing. My problem comes when I am in the static callback with a void * pointing to either a MH_DQ or a MH_CB. If I cast it to the base class the empty MessageHandler::handleMessage(...) method is called, rather than the version in the appropriate derived class. What is the best way to address this situation from a design perspective and/or what language features might help me to implement a solution to my problem? Thanks in advance!

  • Manager property is not available for Full Text Search (SharePoint 2010)

    - by Vijay
    Hi, I had created a web part on MOSS 2007 which displays a organizational chart by searching (Full Text) the user profiles. To identify the subordinates of a user, I used to search for users with the particular user in Manager property. The query looked like this: SELECT AccountName, PreferredName, Manager, WorkEmail FROM scope() WHERE ("SCOPE" = 'People') AND Manager = 'domain\parent_user' But, the same query does not run in SharePoint 2010 as Manager crawled property does not exists. So, I created a new crawled property and mapped it to People:Manager(Text) now, the Manager property is always empty. Even a full crawl after clearing the indexes also not helping. Can anyone please help me in getting manager information in Full Text Search? Thanks in advance!

  • Jquery .text() seems not to work on XML in IE7

    - by volder
    My PHP backend sends XML response to the client (ajax): <response> <code>0</code> <message>OK</message> </response> in the javascript I'm trying to get CODE value in this way: var errorCode = $('code', xml).text(); and then depending on errorCode value I do processing. It is working fine in all browsers I tested except IE7. Instead of CODE value - it is giving me the empty string. The problem is not in 0 value, because I tried to use 5 as a code for example - the result was the same. Any ideas, because I'm stuck with :(( Thanks.

  • Unable to generate a temporary class (result=1). error CS0030: Cannot convert type 'Type[]' to 'Type'?

    - by grady
    I get this error after I created a class from my xsd file using the xsd.exe tool. So I searched the net and found a solution. Here is the link: http://satov.blogspot.com/2006/12/xsdexe-generated-classes-causing.html Problem is that this makes the code run, but somehow the deserialized data seems corrupt. I did what the site suggests and in the end the 2nd array dimension is always empty (see the comments of the site, somebody also had this problem). Question is, how do I solve this issue now? Is there another tool to create the xsd file? I tried Xsd2Code, without success. Thanks :-)

  • Best way to handle storing (possibly NULL) char * in a std::string

    - by John
    class MyClass { public: void setVar(const char *str); private: std::string mStr; int maxLength; //we only store string up to this length }; What's the best approach to implement setVar when the external code is quite likely to pass in NULL for an empty string (and cannot be changed)? I currently do something a bit like: void MyClass::setVar(const char *str) { mStr.assign(str ? str : "",maxLength); } But it seems kind of messy. ideas?

  • If item not in the lst in scheme

    - by ms. sakura
    I'm working on context-free grammars, and I have a function that returns the (terminal values of grammar) for example: i have non-terminal function that results in (A B) , from calling say ((A cat) (B happy np) (A B sad)) so technically A and B are non terminals of the grammar. Now I want to be able to get the terminals (cat happy np sad) (define terminals (lambda (lsts) (cond ((null? lsts) lsts) ((not(member? (car(car lsts)) (n-terminals lsts))) (cons (car(car lsts)) (terminals (car (cdr lsts))))) (else (terminals (cdr lsts)))))) PS: functionality of n-terminals is described above. member? is a boolean function that returns true if an item is a member of the list, false otherwise. My function returns an empty lst. What am I missing here?

  • Add a Component to two different JTabbedPanes

    - by haldean
    I have a LinkedList of Components, each of which I would like to add into two different JTabbedPanes. For some reason, Swing is only letting me put each component into one or the other. The code I'm using is the following: /* The two tab panes */ JTabbedPane leftTabs = new JTabbedPane(); JTabbedPane rightTabs = new JTabbedPane(); for (int i=0; i<tabPanes.size(); i++) { rightTabs.add(tabPanes.get(i)); leftTabs.add(tabPanes.get(i)); } Whichever add call I put last is the one that works; if I add to leftTabs last, then rightTabs ends up empty, and vice-versa. Any ideas on how to get this working? Thanks!

  • Is it possible to make a TListView search by the caption of a different column in Delphi?

    - by James
    Hi, When you set the Caption of a TListItem it seems to always set the Text for the first column in the row. When you start typing in the ListView it will search & select the closest match based on the caption of the first column. I have a situation where I need the caption of the first row to be empty, but still need the search functionality to work as normal (in this case the data I would be searching for may be in the 2nd/3rd column). Is this possible without using any 3rd party controls?

  • Python 2.7 creating a multidimensional list

    - by poop
    I don't know why I am having so much trouble creating a 3 dimensional list. I need the program to create an empty n by n list. So for n = 4: x = [[[],[],[],[]],[[],[],[],[]],[[],[],[],[]],[[],[],[],[]]] I've tried using: y = [n*[n*[]]] y = [[[]]* n for i in range(n)] Which both appear to be creating copies of a reference. I've also tried naieve application of the list builder with little success: y = [[[]* n for i in range(n)]* n for i in range(n)] y = [[[]* n for i in range(1)]* n for i in range(n)] I've also tried building up the array iteratively using loops, with no success. In my rapid flurry of attempts to not post something stupidly easy to SO, I came upon a solution: y = [] for i in range(0,n): y.append([[]*n for i in range(n)]) Is there an easier/ more intuitive way of doing this?

  • trying to understand some codes related to window.onload in js

    <body> <script language="javascript"> window.tdiff = []; fred = function(a,b){return a-b;}; window.onload = function(e){ console.log("window.onload", e, Date.now() ,window.tdiff, (window.tdiff[1] = Date.now()) && window.tdiff.reduce(fred) ); } </script> </body> Above code is taken from a site. In firefox-console, it shows: window.onload load 1372646227664 [undefined, 1372646227664] 1372646227664 Question: For window.tdiff->[undefined, 1372646227664], why not:[], because when runs to code:window.tdiff, it is still an empty array? For window.tdiff.reduce(fred)->1372646227664, window.tdiff = [undefined, 1372646227664], undefined - 1372646227664, should be NaN, why it shows 1372646227664?

  • How can I "undelete" a set of documents in CouchDB?

    - by radicand
    I have a large set of documents in a CouchDB database that were just accidentally bulk deleted using _deleted:true. I also have a backup for this set of data that includes their last known good revision and metadata. I need to maintain the same _id, so simple restore with a new _id is not an option. Compaction has not been run and I can access any of these documents via the &rev= url parameter as well as their attachments (which are needed). What I need to do is "restore" these documents to the revision I have on file. Surprisingly, I have come up empty with any queries on how to achieve this. Tips or hacks appreciated.
