  • Eror while showing returned value on parent window from chield (Dialog box) window using JSF Trinida

    - by Navnath
    Hi There, I am using Myfaces and Trinidad tld's for page design. In that, I am trying to implement Dialog box which will going to open on button click with tacking some value from parent window and return result to Parent window. Now the problem is I can send value to Dialog box and also get return from dialog box successfully, but there is problem to show return value on Parent window because parent window is not reflecting that value and ask for refresh page. When I refresh page, it again open the pop up, i.e. it resending the previous request. Here is my return code. private UIXInput input; public UIXInput getInput() { return input; } public void setInput(UIXInput input) { this.input = input; } public void returned(ReturnEvent event) { if (event.getReturnValue() != null) { getInput().setValue(event.getReturnValue()); RequestContext afContext = RequestContext.getCurrentInstance(); afContext.addPartialTarget(getInput()); } } Next is I have bind input variable with field which need to reflect return value. Here is .jspx code. I have download Trinidad dialog code and try to run on local system, but it not showing any dialog box. But once I remove partialSubmit="true" attribute from comment button which shows dialog box, Then I can see dialog box. Is this attribute making an above error? I hope I have explain my problem clearly. Please...Please let me know any any kind of solution, suggestion. I have spend almost a week to resolve this issue, but.......didn't succeed. Thank You in advance, Navnath Kumbhar.

  • Preprocessor Conditionals

    - by Mike
    I was wondering if it would be possible to have a define which changes values at some point in the code be used in a conditional. Basically something like this: //////////////////////////////////////////// SomeFile.cpp #define SHUTDOWN false while(window->isOpen()) { if(SHUTDOWN) window->close(); // Rest of the main loop } //////////////////////////////////////////// SomeOtherFile.cpp if(Escape.isPressed()) { #undef SHUTDOWN #define SHUTDOWN true } Thus causing the app to close. If it's not, would having a function like RenderWindow* getWindow() { return window; } and then calling if(Escape.isPressed()) getWindow()->close(); The best way to do it? I'd rather not go that route because the classes that are calling the key event are members of the class controlling the main loop and the window, so I'd have to set pointers to the containing class in the smaller classes to call getWindow() and it just seems like a more complicated method. But if I can't do it with preprocessor directives I'll just have to use pointers to the parent class.

  • 'Best' way to pull data relative to a div?

    - by acidzombie24
    This answer suggested i should put my data in JS instead of a textarea. Thinking about it i could have scripts and do something like myarray[i]="data" where i is the index of my for loop. However when i click a div how do i find out what i is? I have used var data = $(this).parent('.parent').find('.valuestr').eq(0).val(); which is extremely simple. Should i use a script or should i continue to do it with a textarea? if i should use a script 1) Whats the easiest way to find i and 2) Is it bad pratice to have dozens or hundreds of <script> in my html? or i can go through the loop twice but i still dont know the easiest way to find i. I would have to store it somewhere or go through multiple tags and count them.

  • calling same function on different buttons not loaded yet

    - by Jordan Faust
    I can not get this to work for every button and I cannot find anything explaining why. I guessing it is something small that I am missing $(document).ready(function() { // delete the selected row from the database $(document).on('click', '#business-area-delete-button', { model: "BusinessArea" }, deleteRow); $(document).on('click', '#business-type-delete-button', { model: "BusinessType" }, deleteRow); $(document).on('click', '#client-delete-button', { model: "Client" }, deleteRow); $(document).on('click', '#client-type-delete-button', { model: "ClientType" }, deleteRow); $(document).on('click', '#communication-channel-type', { model: "CommunicationChannelType" }, deleteRow); $(document).on('click', '#parameter-type-delete-button', { model: "ParameterType" }, deleteRow); $(document).on('click', '#validation-method-delete-button', { model: "ValidationMethod" }, deleteRow); } the event function deleteRow(event){ $.ajax( { type:'POST', data: { id: $(".delete-row").attr("id") }, url:"/mysite/admin/delete" + event.data.model, success:function(data,textStatus){ $('#main-content').html(data); }, error:function(XMLHttpRequest,textStatus,errorThrown){ jQuery('#alerts').html(XMLHttpRequest.responseText); }, complete:function(XMLHttpRequest,textStatus){ placeAlerts() } } ); return false }; This works only for a the button with id validation-method-delete-button. I use document and not the button its self because the button is contained in a template that is loaded later via ajax. I have this working for a similar function that is selecting a row in a table however I am not attempting to pass data in that scenario.

  • How to iterate through an XDocument's Nodes

    - by Ed R
    I am trying to iterate through my xml document's nodes to get the value for <username>Ed</username> in each node. I am using Linq to sort the XDocument first, then attempting to loop through the nodes. I can't seem to find the correct foreach loop to achieve this. Any help is appreciated. var doc = XDocument.Load("files\\config.xml"); var newDoc = new XDocument(new XElement("Config", from p in doc.Element("Config").Elements("Profile") orderby int.Parse(p.Element("order").Value) select p)); foreach (XElement xe in newDoc.Nodes()) { MessageBox.Show(xe.Element("username").Value); }

  • Is it faster to count down than it is to count up?

    - by Bob
    Our computer science teacher once said that for some reason it is more efficient to count down that count up. For example if you need to use a FOR loop and the loop index is not used somewhere (like printing a line of N * to the screen) I mean that code like this : for (i=N; i>=0; i--) putchar('*'); is better than: for (i=0; i<N; i++) putchar('*'); Is it really true? and if so does anyone know why?

  • jQuery how to set click on href in the div?

    - by faya
    Good day, I want to set click event on every anchor element in my div container. Here is an example what I want to do: ---HTML--- <div id="my-container"> <a href="page1.html">page1</a> <a href="page2.html">page2</a> <a href="page3.html">page3</a> </div> ---- jQuery ---- $("#my-container a").click(function() { var link = $(this).attr("href"); $("#my-container").load(link); }); What I want to do is to let me handle loading event of href clicks and load it to the same container. And this is must done without id, class attributes which aren't available for that hrefs. The problem is in this: $("#my-container a"). Any help would be appreciated! Thanks UPDATE People doesn't seem to get right what I wanted to ask. I repeat myself again. $("#my-container a") <---- doesn't add click events on href anchors. So how I can set click event?

  • Why does OpenGL's glDrawArrays() fail with GL_INVALID_OPERATION under Core Profile 3.2, but not 3.3 or 4.2?

    - by metaleap
    I have OpenGL rendering code calling glDrawArrays that works flawlessly when the OpenGL context is (automatically / implicitly obtained) 4.2 but fails consistently (GL_INVALID_OPERATION) with an explicitly requested OpenGL core context 3.2. (Shaders are always set to #version 150 in both cases but that's beside the point here I suspect.) According to specs, there are only two instances when glDrawArrays() fails with GL_INVALID_OPERATION: "if a non-zero buffer object name is bound to an enabled array and the buffer object's data store is currently mapped" -- I'm not doing any buffer mapping at this point "if a geometry shader is active and mode? is incompatible with [...]" -- nope, no geometry shaders as of now. Furthermore: I have verified & double-checked that it's only the glDrawArrays() calls failing. Also double-checked that all arguments passed to glDrawArrays() are identical under both GL versions, buffer bindings too. This happens across 3 different nvidia GPUs and 2 different OSes (Win7 and OSX, both 64-bit -- of course, in OSX we have only the 3.2 context, no 4.2 anyway). It does not happen with an integrated "Intel HD" GPU but for that one, I only get an automatic implicit 3.3 context (trying to explicitly force a 3.2 core profile with this GPU via GLFW here fails the window creation but that's an entirely different issue...) For what it's worth, here's the relevant routine excerpted from the render loop, in Golang: func (me *TMesh) render () { curMesh = me curTechnique.OnRenderMesh() gl.BindBuffer(gl.ARRAY_BUFFER, me.glVertBuf) if me.glElemBuf > 0 { gl.BindBuffer(gl.ELEMENT_ARRAY_BUFFER, me.glElemBuf) gl.VertexAttribPointer(curProg.AttrLocs["aPos"], 3, gl.FLOAT, gl.FALSE, 0, gl.Pointer(nil)) gl.DrawElements(me.glMode, me.glNumIndices, gl.UNSIGNED_INT, gl.Pointer(nil)) gl.BindBuffer(gl.ELEMENT_ARRAY_BUFFER, 0) } else { gl.VertexAttribPointer(curProg.AttrLocs["aPos"], 3, gl.FLOAT, gl.FALSE, 0, gl.Pointer(nil)) /* BOOM! */ gl.DrawArrays(me.glMode, 0, me.glNumVerts) } gl.BindBuffer(gl.ARRAY_BUFFER, 0) } So of course this is part of a bigger render-loop, though the whole "*TMesh" construction for now is just two instances, one a simple cube and the other a simple pyramid. What matters is that the entire drawing loop works flawlessly with no errors reported when GL is queried for errors under both 3.3 and 4.2, yet on 3 nvidia GPUs with an explicit 3.2 core profile fails with an error code that according to spec is only invoked in two specific situations, none of which as far as I can tell apply here. What could be wrong here? Have you ever run into this? Any ideas what I have been missing?

  • Why this search can not generate correct result?

    - by user482742
    Hi, All: Below is to find same customer and if he is in list, the number add one. If he is not in the list, just add him in the list. I use Search function to do this, but failed and generated incorrect records. It can not find the customer or the right number of customers. But if I use For..loop to iterate the list, it does well and can find the customer and add new customer in that for..loop search procedure. (I did not paste for ..loop search procedrue here). Another problem is that there is no difference between setting list.sorted true and false. It seems Search function is not correct. This search function is from an example of delphi textbook. The below is with Delphi 7. Thank you. Procedure Form1.create; begin list:=Tstringlist.create; list.sorted:=true; // Search function will generate exactly Same and Incorrect //records no matter list.sorted is set true or false. list.duplicates:=dupignore; .. end; Procedure addcustomer; var .. begin while p1.MatchAgain do begin //p1 is regular expression customer:=p1.MatchedExpression; if (search(customer)=false) then begin list.Add(customer+'=1'); end; allcustomer:=allcustomer+1; .. end; Function Tform1.search(customer: string): boolean; var fre:string; num:integer; L:integer; R:integer; M: Integer; CompareResult: Integer; found: boolean; begin result:=false; found:=false; L := 0; R := List.Count - 1; while (L <= R) and ( not found ) do begin M := (L + R) div 2; CompareResult := Comparetext(list.Names[m]), customer); if (compareresult=0) then begin fre:=list.ValueFromIndex [m]; num:=strtoint(fre); num:=num+1; list.ValueFromIndex[m]:=inttostr(num); Found := True; Result := true; exit; end else if compareresult > 0 then r := m - 1 else l := m + 1; end; end;

  • Iterating multple lists consecutively (C++)

    - by Graham Rogers
    I have 3 classes, 2 inheriting from the other like so: class A { public: virtual void foo() {cout << "I am A!" << endl;} }; class B : public A { public: void foo() {cout << "B pretending to be A." << endl} void onlyBFoo() {cout << "I am B!" << endl} }; class C : public A { public: void foo() {cout << "C pretending to be A." << endl} void onlyCFoo() {cout << "I am C!" << endl} }; What I want to do is something like this: list<A> list_of_A; list<B> list_of_B; list<C> list_of_C; //put three of each class in their respective list for (list<B>::iterator it = list_of_B.begin(); it != list_of_B.end(); ++it) { (*it).onlyBFoo(); } for (list<C>::iterator it = list_of_C.begin(); it != list_of_C.end(); ++it) { (*it).foo(); } //This part I am not sure about for (list<A>::iterator it = list_of_all.begin(); it != list_of_all.end(); ++it) { (*it).foo(); } To output: I am B! I am B! I am B! I am C! I am C! I am C! I am A! I am A! I am A! B pretending to be A. B pretending to be A. B pretending to be A. C pretending to be A. C pretending to be A. C pretending to be A. Basically, sometimes I want to only loop the Bs and Cs so that I can use their methods, but sometimes I want to loop all of them so that I can use the same method from each i.e. iterate the As, then the Bs, then the Cs all in one loop. I thought of creating a separate list (like the code above) containing everything, but it would create lots of unnecessary maintenance, as I will be adding and removing every object from 2 lists instead of one.

  • Flex/Flash: Don't show 'bar' cursor when dragging over a TextField/TextArea?

    - by David Wolever
    As the title suggests, how can I prevent the "bar" cursor from appearing when I click-and-drag over a TextField? For example, consider this interaction: I'd like to prevent the cursor changing to the "bar" in step "2". How can I do that? I've tried fiddling with the selectable flag: protected static function fixMouseOverAfordance(field:TextField):void { var iOwnClick:Boolean = false; function handleMouseOver(event:MouseEvent):void { if (event.buttonDown) { field.selectable = iOwnClick; } else { field.selectable = true; iOwnClick = false; } } field.addEventListener(MouseEvent.MOUSE_OVER, handleMouseOver, false, EventPriority.CURSOR_MANAGEMENT+1); field.addEventListener(MouseEvent.ROLL_OVER, handleMouseOver, false, EventPriority.CURSOR_MANAGEMENT+1); field.addEventListener(MouseEvent.MOUSE_MOVE, handleMouseOver, false, EventPriority.CURSOR_MANAGEMENT+1); field.addEventListener(MouseEvent.MOUSE_DOWN, function(event:MouseEvent):void { iOwnClick = true; field.selectable = true; }); } But the "bar" cursor still appears the first time the mouse is moved over the text field (however, after it has been moved out then moved back in, it does the right thing).

  • Multiple forms + HAML + jQuery + Javascript submit

    - by Jay Godse
    Hi. I have a HAML page that lists some links to delete "things" that looks like this %div %a.form_submit Delete Thing 1 %form{:href=>"#", :id=>'comment_1', :method=>'post', :action=>'/thing/delete'} %input{:type=>'hidden', :name=>'thingid', :value=>'1'} %input{:type=>'submit', style='display:none'} %div %a.form_submit Delete Thing 22 %form{:href=>"#", :id=>'comment_22', :method=>'post', :action=>'/thing/delete'} %input{:type=>'hidden', :name=>'thingid', :value=>'22'} %input{:type=>'submit', style='display:none'} The intention is to have a link "Delete XX" which will delete something specific. A page could have a number of these links, and each link is for a specific "thing". I also have a piece of (unobtrusive) jQuery javascript that adds a click handler to each form as follows: $('a.form_submit').click(function(event) { $('form').submit(); event.preventDefauilt(); }); This works when there is one form on a page. However, if I have more than one form on a page, how do I ensure that clicking "Delete Thing 1" will trigger a submit() event only on the form with id='comment_1'?

  • SASS color array

    - by Eric Holmes
    I am trying to write a loop that will cycle through colors and condense the amount of code in my scss file. Here is a simple example of what I have: $color1: blue; $color2: red; $color3: white; $color4: black; .color1-bg { background-color: $color1; } .color2-bg { background-color: $color2; } .color1-border { border-color: $color1; } .color2-border { border-color: $color2; } And so on. I am looking for a way to make the equivalent of a foreach loop, and cycle through an 'array' of colours by index. Something like this: @each $color in $color1, $color2, $color3, $color4 { .{$color}-bg { background-color: $color; .{$color}-border { border-color: $color; } I know the syntax is wrong, but that is my thinking process. Thanks for the help!

  • Passing data to a jQuery click() function

    - by jakenoble
    Hi I have a simple span like so <span class="action removeAction">Remove</span> This span is within a table, each row has a remove span. And then I call a URL using AJAX when that span is clicked. The AJAX event needs to know the ID of the object for that row? What is the best way of getting that ID into the click function? I thought I could do something like this <span class="action removeAction" id="1">Remove</span> But an ID should not start with a number? Right? Then I thought I could do <span class="action removeAction" id="my1">Remove</span> Then just strip the 'my' part from the ID, but that just seems Yuk! Below is my click event and where my AJAX event is. <script type="text/javascript" language="text/javascript"> $(document).ready(function() { $(".removeAction").click(function() { //AJAX here that needs to know the ID } }); </script> I am sure there is a nice way of doing this? Thanks. Jake.

  • Modify bash variables with sed

    - by Alexander Cska
    I am trying to modify a number of environmental variables containing predefined compiler flags. To do so, I tried using a bash loop that goes over all environmental variables listed with "env". for i in $(env | grep ipo | awk 'BEGIN {FS="="} ; { print $1 } ' ) do echo $(sed -e "s/-ipo/ / ; s/-axAVX/ /" <<< $i) done This is not working since the loop variable $i contains just the name of the environmental variable stored as a character string. I tried searching a method to convert a string into a variable but things started becoming unnecessary complicated. The basic problem is how to properly supply the environmental variable itself to sed. Any ideas how to properly modify my script are welcome. Thanks, Alex

  • Finding open contiguous blocks of time for every day of a month, fast

    - by Chris
    I am working on a booking availability system for a group of several venues, and am having a hard time generating the availability of time blocks for days in a given month. This is happening server-side in PHP, but the concept itself is language agnostic -- I could be doing this in JS or anything else. Given a venue_id, month, and year (6/2012 for example), I have a list of all events occurring in that range at that venue, represented as unix timestamps start and end. This data comes from the database. I need to establish what, if any, contiguous block of time of a minimum length (different per venue) exist on each day. For example, on 6/1 I have an event between 2:00pm and 7:00pm. The minimum time is 5 hours, so there's a block open there from 9am - 2pm and another between 7pm and 12pm. This would continue for the 2nd, 3rd, etc... every day of June. Some (most) of the days have nothing happening at all, some have 1 - 3 events. The solution I came up with works, but it also takes waaaay too long to generate the data. Basically, I loop every day of the month and create an array of timestamps for each 15 minutes of that day. Then, I loop the time spans of events from that day by 15 minutes, marking any "taken" timeslot as false. Remaining, I have an array that contains timestamp of free time vs. taken time: //one day's array after processing through loops (not real timestamps) array( 12345678=>12345678, // <--- avail 12345878=>12345878, 12346078=>12346078, 12346278=>false, // <--- not avail 12346478=>false, 12346678=>false, 12346878=>false, 12347078=>12347078, // <--- avail 12347278=>12347278 ) Now I would need to loop THIS array to find continuous time blocks, then check to see if they are long enough (each venue has a minimum), and if so then establish the descriptive text for their start and end (i.e. 9am - 2pm). WHEW! By the time all this looping is done, the user has grown bored and wandered off to Youtube to watch videos of puppies; it takes ages to so examine 30 or so days. Is there a faster way to solve this issue? To summarize the problem, given time ranges t1 and t2 on day d, how can I determine the remaining time left in d that is longer than the minimum time block m. This data is assembled on demand via AJAX as the user moves between calendar months. Results are cached per-page-load, so if the user goes to July a second time, the data that was generated the first time would be reused. Any other details that would help, let me know. Edit Per request, the database structure (or the part that is relevant here) *events* id (bigint) title (varchar) *event_times* id (bigint) event_id (bigint) venue_id (bigint) start (bigint) end (bigint) *venues* id (bigint) name (varchar) min_block (int) min_start (varchar) max_start (varchar)

  • Performing an action on Parent/Child elements independently.

    - by Matt Weldon
    I have HTML similar to the following in my page <div id="someDiv"> <img src="foo.gif" class="someImg" /> </div> The wrapper div is set up such that when it is clicked, it's background-color changes using the following jQuery code. $("div").click(function(event){ $(this).css("background-color", "blue"); }); I also have some jQuery associated with my img that will do some other function (for the sake of argument I am going to display and alert box) like so: $("img[class=someImg]").click(function(event){ alert("Image clicked"); }); The issue I have come across is that when I click on the img, the event associated with the div is also triggered. I'm pretty sure that this is due to the way that jQuery (or indeed JavaScript) is handling the two DOM elements - clicking the img would require you to also technically click the div, thus triggering both events. Two questions then really: Is my understanding of the DOM/JavaScript flawed in some way or is this actually how things are occurring? Are there any jQuery methods that would allow me to perform actions on a child element without invoking those associated with its parent?

  • Enum : get the keys list

    - by Damien MATHIEU
    Hello, I'm not a java developer. But I'm currently taking a look at Android applications development so I'm doing a bit of nostalgy, doing some java again after not touching it for three years. I'm looking forward using the "google-api-translate-java" library. In which there is a Language class. It's an enum allowing to provide the language name and to get it's value for Google Translate. I can easily get all the values with : for (Language l : values()) { // Here I loop on one value } But what I'd want to get is a list of all the keys names (FRENCH, ENGLISH, ...). Is there something like a "keys()" method that'd allow me to loop through all the enum's keys ?

  • Progressbar behaves strangely

    - by wanderameise
    I just created an application in C# that uses a thread which polls the UART for a receive event. If data is received an event is triggered in my main thread (GUI) and a progress bar is controlled via PerformStep() method (of course, I previously set the Max value accordingly). PerformStep is invoked using the following expression to handle cross threading this.Invoke((Action)delegate{progressBar2.PerformStep();}) When running this application the progressbar never hits its final value. It stops at 80%. When debugging and stopping at the line mentioned above, everything works fine using single steps. I have no idea what is going one! Start read thread on main thread: pThreadWrite = new Thread(new ThreadStart(ReadThread)); pThreadWrite.Start(); Read Thread: private void ReadThread() { while(1) { if (ReceiveEvent) { FlashProgressBar(); } } } Event that is triggered in main thread: private void FlashProgressBar() { this.Invoke((Action)delegate { progressBar2.PerformStep();}); } (It's a simplified representation of my code) It seems as if the internal progress is faster than the visual one.
