  • How to read a parameter passed to a facelet from a backing bean

    - by Antonio
    Hi, I've written a facelet, and a corresponding backing bean, that implements user management (addition, deletion and so on). I'd want to be able to perform some custom processing when, for instance, a new user is added. There is a "create" button in the facelet, whose click event is handled by its backing bean. At the end of the event handler, I'd want to be able to call a method of another backing bean, which is not known because ideally the facelet can be used in several pages, with different custom processing. I thought to implement this feature by providing to the facelet a backing bean name and a method name, like this: <myfacelet:subaccounts backingBean="myBackingBean" createListener="createListener" /> and at the end of the event handler call #{myBackingBean.createListener} someway. I'm using this method (along with some overloads) to obtain a MethodExpression: protected MethodExpression getMethodExpression(String beanName, String methodName, Class<?> expectedReturnType, Class<?>[] expectedParamTypes) { ExpressionFactory expressionFactory; MethodExpression method; ELContext elContext; String el; el = String.format("#{%s['%s']}", beanName, methodName); expressionFactory = getApplication().getExpressionFactory(); elContext = getFacesContext().getELContext(); method = expressionFactory.createMethodExpression(elContext, el, expectedReturnType, expectedParamTypes); return method; } and the click event handler should look like: public void saveSubaccountListener(ActionEvent event) { MethodExpression method; ... method = getMethodExpression( "backingBean", "createSubaccountListener", SubuserBean.class); if (method != null) method.invoke( getFacesContext().getELContext(), new Object[] { _editedSubuser }); } That works fine as long as I provide an existing bean name (myBackingBean), but if I use backingBean the invoke() doesn't work due to the following error: javax.el.PropertyNotFoundException: Target Unreachable, identifier 'backingBean' resolved to null Is there a way I can retrieve from the facelet backing bean the value of a parameter that has been passed to the facelet? In my case, the value of backingBean, which should be myBackingBean? I've searched for and tried different solutions, but with no luck yet.

  • Decomposing a rotation matrix

    - by DeadMG
    I have a rotation matrix. How can I get the rotation around a specified axis contained within this matrix? Edit: It's a 3D matrix (4x4), and I want to know how far around a predetermined (not contained) axis the matrix rotates. I can already decompose the matrix but D3DX will only give the entire matrix as one rotation around one axis, whereas I need to split the matrix up into angle of rotation around an already-known axis, and the rest. Sample code and brief problem description: D3DXMATRIX CameraRotationMatrix; D3DXVECTOR3 CameraPosition; //D3DXVECTOR3 CameraRotation; inline D3DXMATRIX GetRotationMatrix() { return CameraRotationMatrix; } inline void TranslateCamera(float x, float y, float z) { D3DXVECTOR3 rvec, vec(x, y, z); #pragma warning(disable : 4238) D3DXVec3TransformNormal(&rvec, &vec, &GetRotationMatrix()); #pragma warning(default : 4238) CameraPosition += rvec; RecomputeVPMatrix(); } inline void RotateCamera(float x, float y, float z) { D3DXVECTOR3 RotationRequested(x, y, z); D3DXVECTOR3 XAxis, YAxis, ZAxis; D3DXMATRIX rotationx, rotationy, rotationz; XAxis = D3DXVECTOR3(1, 0, 0); YAxis = D3DXVECTOR3(0, 1, 0); ZAxis = D3DXVECTOR3(0, 0, 1); #pragma warning(disable : 4238) D3DXVec3TransformNormal(&XAxis, &XAxis, &GetRotationMatrix()); D3DXVec3TransformNormal(&YAxis, &YAxis, &GetRotationMatrix()); D3DXVec3TransformNormal(&ZAxis, &ZAxis, &GetRotationMatrix()); #pragma warning(default : 4238) D3DXMatrixIdentity(&rotationx); D3DXMatrixIdentity(&rotationy); D3DXMatrixIdentity(&rotationz); D3DXMatrixRotationAxis(&rotationx, &XAxis, RotationRequested.x); D3DXMatrixRotationAxis(&rotationy, &YAxis, RotationRequested.y); D3DXMatrixRotationAxis(&rotationz, &ZAxis, RotationRequested.z); CameraRotationMatrix *= rotationz; CameraRotationMatrix *= rotationy; CameraRotationMatrix *= rotationx; RecomputeVPMatrix(); } inline void RecomputeVPMatrix() { D3DXMATRIX ProjectionMatrix; D3DXMatrixPerspectiveFovLH( &ProjectionMatrix, FoV, (float)D3DDeviceParameters.BackBufferWidth / (float)D3DDeviceParameters.BackBufferHeight, FarPlane, NearPlane ); D3DXVECTOR3 CamLookAt; D3DXVECTOR3 CamUpVec; #pragma warning(disable : 4238) D3DXVec3TransformNormal(&CamLookAt, &D3DXVECTOR3(1, 0, 0), &GetRotationMatrix()); D3DXVec3TransformNormal(&CamUpVec, &D3DXVECTOR3(0, 1, 0), &GetRotationMatrix()); #pragma warning(default : 4238) D3DXMATRIX ViewMatrix; #pragma warning(disable : 4238) D3DXMatrixLookAtLH(&ViewMatrix, &CameraPosition, &(CamLookAt + CameraPosition), &CamUpVec); #pragma warning(default : 4238) ViewProjectionMatrix = ViewMatrix * ProjectionMatrix; D3DVIEWPORT9 vp = { 0, 0, D3DDeviceParameters.BackBufferWidth, D3DDeviceParameters.BackBufferHeight, 0, 1 }; D3DDev->SetViewport(&vp); } Effectively, after a certain time, when RotateCamera is called, it begins to rotate in the relative X axis- even though constant zero is passed in for that request when responding to mouse input, so I know that when moving the mouse, the camera should not roll at all. I tried spamming 0,0,0 requests and saw no change (one per frame at 1500 frames per second), so I'm fairly sure that I'm not seeing FP error or matrix accumulation error. I tried writing a RotateCameraYZ function and stripping all X-axis from the function. I've spent several days trying to discover why this is the case, and eventually decided on just hacking around it. Just for reference, I've seen some diagrams on Wikipedia, and I actually have a relatively strange axis layout, which is Y axis up, but X axis forwards and Z axis right, so Y axis yaw, Z axis pitch, X axis roll.

  • Cascading KVM switches

    - by einpoklum
    I have a not-so-small number of computers (say, 5) which I want to access with a single keyboard, USB and monitor. I can get an 8-port KVM switch, which is a pretty expensive piece of hardware; however, in theory, I should be able to cascade KVM switches: Have one 4-port KVM switch between 2 other KVMs (a 2-port and a 4-port). Is this doable (with typical off-the-shelf switches and cables)? Has anyone had experience doing this? Note: I'm interested in USB-only for the keyboard and mouse, and either VGA or DVI for the display. Audio and PS/2 connections are irrelevant for me..

  • Both screens always stay on after adding second monitor

    - by J.Merrill
    I had a single 1920x1080 monitor on a Windows 7 desktop PC and, per "power management" (not screen saver), the screen would go blank after 10 minutes. I added another monitor (2560x1600 if that matters) and since then, neither screen has ever blanked. I've tried turning on the "blank" screen saver, but that didn't help either -- I can go away for hours and when I come back, both screens are on. I've seen others with similar issues apparently caused by e.g. wireless mice that seem to move infinitesimally, but I've got the same wired mouse I had before. I can't understand why neither the screen saver nor power management is doing what it should to blank the screens, when "power management" used to do it when there was only one monitor. Maybe it doesn't matter so much with current LCD display technology (no "burn in") but doesn't a monitor use more power when "power management" hasn't turned off the display? Thanks for any suggestions.

  • jQuery - Unchecking checkboxes that act like radio buttons

    - by Cecil
    Hey All, I have the following jQuery code to make my checkboxes act like radio buttons, so that only 1 of the 3 can be checked at a time. <script type="text/javascript" language="javascript"> $(document).ready(function() { $("#testing input:checkbox").change(function(){ var checkname = $(this).attr("name"); $("input:checkbox[name='" + checkname + "']").removeAttr("checked"); this.checked = true; }); }); </script> The checkboxes are layed out like the following: <input type="checkbox" id="testing" name="testing" value="B"> <input type="checkbox" id="testing" name="testing" value="I"> <input type="checkbox" id="testing" name="testing" value="A"> This works exactly how i want it to work, not a problem, except once i click one of the 3, i cant unclick it so that none of them are checked, this is what i want to happen, so along with being only able to click one at a time, im able to uncheck them completely. Any help would be grand :)

  • How can I stop the browser viewport moving to the top of the page when the user clicks on a jQueryUI radio button?

    - by ben
    I have got some radio buttons setup like this: <div id="typeRadios"> <input id="note_notetype_note1" name="note[notetype]" type="radio" value="note1" /><label for="note_notetype_note1">note1</label> <input id="note_notetype_note2" name="note[notetype]" type="radio" value="note2" /><label for="note_notetype_note2">note2</label> </div> That I turn into jQueryUI buttons like this: $("#typeRadios").buttonset(); This is the resulting HTML: <input type="radio" value="note1" name="note[notetype]" id="note_notetype_note1" class="ui-helper-hidden-accessible"> <label for="note_notetype_note1" aria-pressed="false" class="ui-button ui-widget ui-state-default ui-button-text-only ui-corner-left" role="button" aria-disabled="false"><span class="ui-button-text">note1</span></label> <input type="radio" value="note2" name="note[notetype]" id="note_notetype_note2" class="ui-helper-hidden-accessible"> <label for="note_notetype_note2" aria-pressed="false" class="ui-button ui-widget ui-state-default ui-button-text-only ui-corner-left" role="button" aria-disabled="false"><span class="ui-button-text">note2</span></label> The buttons work, but whenever I click one, the browser view-port gets returned to the top of the page, the same way it happens when you click on a <a href="#">link</a> link. I am using jQuery 1.4.2 and jQueryUI 1.8.7. How can I prevent this behaviour? Thanks for reading. EDIT: The <a href="#">link</a> part was missing.

  • Advise guidance on how to form this jQuery script for show/hide fade element

    - by Rick
    Hey guys.. I basically have several links on the left side of the screen and on the right is a preview window. Below the preview window is another box for the affiliate link code. So what I am trying to do is create an affiliate page where you choose the banner size on the left by clicking on the link and on the right you see it dynamically change to the banner size and the code changes accordingly as well. So far I have the following code and it works but it seems very very cumbersome and bloated. Can you see if I can trim this down? jQuery(".banner-style li").click(function() { jQuery(".banner-style li").removeClass("selected"); jQuery(this).addClass("selected"); var $banner = jQuery(this).attr("class"); $banner = $banner.replace(" selected",""); jQuery(".preview img").fadeOut('fast',function() { jQuery(".preview img").attr("src", "http://localhost/site/banners/"+$banner+".jpg") .fadeIn('slow'); }); jQuery(".code p").removeClass('hide').hide(); jQuery(".code p."+$banner).show(); }); Also to note the funny thing is in FF, when you click for the first to on any link, the original image on the right fades out and in real quick and then it loads the "clicked" image. This does not happen in other browsers...

  • How to stop the submission of the form using JQUERY?

    - by Param-Ganak
    Hello frineds! I have a form which have many check boxes in it. User will check one or many checkboxes and click on Delete button which is actually submit button then the respective records for selected check boxes are get deleted. Required operation steps are as follows:- When user selects one or more checkboxes and clicks the submit button then a JQUERY code is get executed in which It should checks that if any check box is selected; if not; then is displays alert message and do not submit the form. If it founds that one or more checkboxes are selected it should ask user for his/her confirmation using confirm alert box about the confirmation of deletion. If user press YES button on confirm box then it should submit the form using javascript submit statement. If user pressed the NO button then it should unchecks the checked selected checkboxes and should not submit the form. This is the JQUERY code I had written. $(document).ready(function (){ $("#id_delete").click(function(){ var temp=$("#id_frm input:checkbox:checked"); var len=temp.length; if(len==0) { alert("Please select the order."); } else { if(confirm("Are you sure to delete the selected orders.")) { $("#id_frm").submit(); } else { temp.checked=false; } } }); }); Problems: This code is not working properly. Here 1. It submits form when there is no check box is selected. 2. It submits the form when user press NO button on confirmation dialog box. Please guide me friends in this problem.

  • addEventListener pass caller as argument

    Hi, I have the following code. And my problem is that when clicking, the event is firing but the argument passed is not the correct one. It is passing the last dynamically created row i.e. dataStructure.length value. Anyone knows a solution how to get around this? var table = document.getElementById('output'); for(i =0; i<dataStructure.length; i++){ var row = document.createElement('tr'); row.setAttribute('id', i); var url = dataStructure[i].url; if(document.addEventListener) row.addEventListener('click', function(){handleRowClick(i);}, false); var obj = dataStructure[i]; var cellCount = 0; for(field in obj){ var cell = document.createElement('td'); cell.setAttribute('id', cellCount++); //cell.addEventListener('click', function(){window.open(dataStructureObj.links[i].url);}, false); cell.innerHTML = obj[field]; row.appendChild(cell); } cellCount = 0; table.appendChild(row); } } function handleRowClick(rowClicked){ var rowHTML = rowClicked.innerHTML; var cells = rowHTML.getElementsByTagName('td'); for(cell in cells) { alert(cell.value); } window.open(cells[1].innerHTML); }

  • How to create a new text file in DOS with the end result allowing me to rename the file?

    - by Rolo
    I would like an exact duplicate of the following procedure on a Windows computer using mouse clicks: Right Click in a directory and choose New and then Text Document. When one does this, the text file is created with a default name of New Text Document AND it is also highlighted so that I can type in my own file name. I would like to do this in DOS. I don't care what file name is originally created. What I want is for the name of the file to automatically be highlighted / able to be renamed, so that I can rename it. How can DOS execute / simulate a rename command / an F2 being pressed on the keyboard to a file that it has just created?

The last alert shows that the value of the bool variable is "true". However, when I do page source views of the hidden variable, below is the result. The values of the hidden variable when the page loads and when the last alert button finishes are as follows: My local machine: The remote machine: As you can see, the value on my machine is set to true when the process executes. However, on the remote machine, it is set to false where it then doesn't excute. Why isn't the value in the model being returned as TRUE on the remote machine?

  • JQuery: how to use "delegate" instead of "live"?

    - by JacobD
    I've read countless articles how using the JQuery delegate is much more efficient than using the "live" event. As such, I'm having trouble converting my existing Live code to using Delegate. $("#tabs li:eq(0)").live('click',function(){ //...code }); $('#A > div.listing, #B > div.listing, #C > div.listing').live('mouseover',function(){ // ...code }); When I replace the previous code with what I assume is more efficient delegate code, my page doesn't load. $("#tabs li:eq(0)").delegate('click',function(){ //...code }); $('#A > div.listing, #B > div.listing, #C > div.listing').delegate('mouseover',function(){ // ...code }); Any idea why my delegate code doesn't work? Also, any suggestions on how to make this more efficient? UPDATE: The think part of the problem is that, both "#tabs" and "#A, #B, #C" are't present on the web page at page load. Those attributes are dynamically inserted onto the page with an AJAX call. As such, does that mean I have to use live over delegate?

    As usually seemingly simple things take days to resolve, maybe someone could point me to a solution but after 2 days I give up on the following problem; In html, in a form I have a button that is supposed to trigger loading of data through ajax call: <button type="" class="btn" onclick="getData(); return false;">Show Data</button> in javascript: $(document).ajaxStart(function() { $("#qloader").show(); }).ajaxStop(function() { $("#qloader").hide('slow'); });? and in html div with id qloader is defined with 100% width and height and spinner centered as the background, z-index above other: <div id="qloader" class="myLoader" >&nbsp;</div> Now, when page loads, ajax call is executed to get initial data, qloader div is brought up and it shows the spinner - animated, after ajax call finishes, qloader is hidden by ajaxStop. Next, when I click on a button (show data) to initiate another ajax call, ajaxStart is triggered, but it does not show qloader, it waits until ajaxStop is triggered and then in a blink of eye it shows qloader and hides it. I suspected that ajaxStart is not executed, so I put alert before $("#qloader").show(), then alert would be displayed and after that qloader WOULD be displayed BUT spinner animation would be suspended - no spinning, and after ajaxStop it would get hidden. Without alert in ajaxStart trigger, in subsequent ajax calls div is not shown until just before ajaxStop is triggered. It works fine for the first ajax call, but for subsequent ajax call triggered by click on form button it does not work. Any idea what is wrong with this setup?

  • How to refresh jQuery Selector Value after an execution?

    - by Devyn
    Hi, I have like this. $(document).ready(function() { var $clickable_pieces = $('.chess_piece').parent(); $($clickable_pieces).addClass('selectee'); // add selectee class var $selectee = $('.chess_square.selectee'); // wait for click $($selectee).bind('click',function(){ $('.chess_square.selected').removeClass('selected'); $(this).addClass('selected'); { ........... } }); I initially inject 'selectee' class to all div which has 'chess_piece' class then I select DIVs with that class $('.chess_square.selectee'). <div id="clickable"> <div id="div1" class="chess_square"> </div> <div id="div2" class="chess_square selectee"> <div id="sub1" class="chess_piece queen"></div> </div> <div id="div3" class="chess_square"> </div> </div> There are two type of DIV element with class named 'chess_square selectee' and 'chess_square' which doesn't meant to be clickable. I move around Sub DIV of 'rps_square selectee' from DIV2 to DIV1 and add and remove classes to be exactly same like this. The meaning is Queen Piece is moved from Div2 to Div1. <div id="div1" class="chess_square selectee"> <div id="sub1" class="chess_piece queen"></div> </div> <div id="div2" class="chess_square"> </div> <div id="div3" class="chess_square"> </div> However, the problem is jQuery doesn't update var $selectee = $('.rps_square.selectee');. Even though I changed class names, DIV1 is not clickable and DIV2 is still clickable. By the way, I've used jQuery UI selectable but doesn't refresh either.

  • Need help getting Wysihat to work

    - by slythic
    Hi all, I'm using Wysihat in a rails project and am stumped by it's inability to bind to my textarea named post_description (model name Post field name description). I have the following in my head tag: <%= javascript_include_tag 'prototype_1.7'%> <%= javascript_include_tag 'wysihat' %> <script type="text/javascript" charset="utf-8"> document.on("dom:loaded", function() { var editor = WysiHat.Editor.attach('post_description'); var toolbar = new WysiHat.Toolbar(editor); toolbar.addButtonSet(WysiHat.Toolbar.ButtonSets.Basic); // Hide our error message if the editor loads fine $('error').hide(); }); </script> I'm able to see Wysihat works (the bold, italic, and underline tools are shown and when click works as intended). The following in the source of the posts/new HTML: <div id="post_description_editor" class="editor" contenteditable="true"></div> <textarea cols="40" id="post_description" name="post[description]" rows="20" style="display: none; "></textarea> However, when I type something in the description field and click submit the post validation fails saying the description field is empty. Anyone have any clue on how I can get this to work? Thanks in advance!

  • touchscreen in dual monitors but not as primary

    - by bazzjedi
    Hi, I have been looking for information about using a second monitor but thought of using a touchscreen will a touchscreen monitor work in dual set up, but not set up as main monitor which is the question. Can't find any information on this only when others set it has main. only this piece If you mean do the touch screen features still work on the other machine, the answer is yes. Past that, you can even see some of the touch screen features on a non touch screen monitor (just not the multi touch features!) For example, on the taskbar, click (without releasing) on any icon and then drag the mouse up, and you will see that it does the same as using your finger and dragging up. link|flag answered Feb 5 '10 at 15:14 Wil 47.4k125 have hp 2510 main thinking of hp2310ti touchscreen as secondary, grafic card geforce gtx 295- windows 7 professional regards bazzjedi

  • Can't access dynamically generated div with Jquery

    - by Bug Magnet
    Still trying to get my head around JQuery and dynamically generated content. I have the following code that is dynamically generated with JQuery whenever a user clicks on an 'Add' button: <div id="practices_div" style="border-top: 1px dotted gray"> <br/> <a href="#" class="remove_link" rel="practices_div">Remove</a> ....content goes here </div> The JQuery code that dynamically loads the above content is as follows: $.ajax({ url: '/addAjax.html', success: function(response) { $('#container').append(response); } }); What I'm trying to do is when a user clicks on the Remove link, JQuery should hide and delete the dynamically generated content from the page. The code that does this is as follows: $('.remove_link').live('click', function() { if (confirm("Remove this item?")) { $('#practices_div').fadeOut('medium', function() { $(this).remove(); }); } return false; }); So, when the content is dynamically loaded via Ajax, and I click on the Remove link, the Confirmation dialogue box is displayed and if I confirm, nothing happens. For some reason, JQuery is not able find the dynamically generated #practices_div. Any idea what I may be doing wrong?

  • Auto scale and rotate images

    - by Dave Jarvis
    Given: two images of the same subject matter; the images have the same resolution, colour depth, and file format; the images differ in size and rotation; and two lists of (x, y) co-ordinates that correlate the images. I would like to know: How do you transform the larger image so that it visually aligns to the second image? (Optional.) What are the minimum number of points needed to get an accurate transformation? (Optional.) How far apart do the points need to be to get an accurate transformation? The transformation would need to rotate, scale, and possibly shear the larger image. Essentially, I want to create (or find) a program that does the following: Input two images (e.g., TIFFs). Click several anchor points on the small image. Click the several corresponding anchor points on the large image. Transform the large image such that it maps to the small image by aligning the anchor points. This would help align pictures of the same stellar object. (For example, a hand-drawn picture from 1855 mapped to a photograph taken by Hubble in 2000.) Many thanks in advance for any algorithms (preferably Java or similar pseudo-code), ideas or links to related open-source software packages.

  • How to copy a variable in JavaScript?

    - by Michael Stum
    I have this JavaScript code: for (var idx in data) { var row = $("<tr></tr>"); row.click(function() { alert(idx); }); table.append(row); } So I'm looking through an array, dynamically creating rows (the part where I create the cells is omitted as it's not important). Important is that I create a new function which encloses the idx variable. However, idx is only a reference, so at the end of the loop, all rows have the same function and all alert the same value. One way I solve this at the moment is by doing this: function GetRowClickFunction(idx){ return function() { alert(idx); } } and in the calling code I call row.click(GetRowClickFunction(idx)); This works, but is somewhat ugly. I wonder if there is a better way to just copy the current value of idx inside the loop? While the problem itself is not jQuery specific (it's related to JavaScript closures/scope), I use jQuery and hence a jQuery-only solution is okay if it works.
