Adding an unknown number of JComponents to a JPanel

- by Matthew

Good day, I am building an Applet (JApplet to be exact) and I sub divided that into two panels. The top panel is called DisplayPanel which is a custom class that extends JPanel. The bottom panel is called InputPanel which also extends JPanel. As mentioned above, I can add those two Panel's to the applet and they display fine. The next thing that I would like to do is have the InputPanel be able to hold a random number of JComponent Objects all listed veritcally. This means that the InputPanel should be able to have JButtons, JLabels, JTextFields etc thrown at it. I then want the InputPanel to display some sort of scrolling capability. The catch is that since these two panels are already inside my applet, I need the InputPanel to stay the same size as it was given when added to the Applet. So for example, if my applet (from the web-browser html code) was given the size 700,700, and then the DisplayPanel was 700 by 350, and the InputPanel was below it with the same dimensions, I want to then be able to add lots of JComponents like buttons, to the InputPanel and the panel would stay 700 x 350 in the same position that it is at, only the panel would have scroll bars if needed. I've played with many different combinations of JScrollPane, but just cannot get it. Thank you.

TEXTAREAs scroll by themselves (on IE8) every time you type one character

- by Justin Grant

IE8 has a known bug (per connect.microsoft.com) where typing or pasting text into a TEXTAREA element will cause the textarea to scroll by itself. This is hugely annoying and shows up in many community sites, including Wikipedia. The repro is this: open the HTML below with IE8 (or use any long page on wikipedia which will exhibit the same problem until they fix it) size the browser full-screen paste a few pages of text into the TEXTAREA move the scrollbar to the middle position now type one character into the textarea Expected: nothing happens Actual: scrossing happens on its own, and the insertion point ends up near the bottom of the textarea! Below is repro HTML (can also see this live on the web here: http://en.wikipedia.org/w/index.php?title=Text_box&action=edit) <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <body> <div style="width: 80%"> <textarea rows="20" cols="80" style="width:100%;" ></textarea> </div> </body> </html>

Some languages don't work when using Word 2007 Spellcheck from Interop

- by Tridus

I'm using the Word 2007 spellchecker via Interop in a VB.net desktop app. When using the default language (English), it works fine. If I set the language to French via LanguageId, it also works. But if I set it to French (Canadian) (Word.WdLanguageID.wdFrenchCanadian), it doesn't work. There's no error message, it simply runs and says the document contains no errors. I know it does, if I paste the exact same text into Word itself and run it with the French (Canadian) dictionary, it finds errors. Just why that dictionary doesn't work is kind of a mystery to me. Full code below: Public Shared Function SpellCheck(ByVal text As String, ByVal checkGrammar As Boolean) As String ' If there is no data to spell check, then exit sub here. If text.Length = 0 Then Return text End If Dim objWord As Word.Application Dim objTempDoc As Word.Document ' Declare an IDataObject to hold the data returned from the ' clipboard. Dim iData As IDataObject objWord = New Word.Application() objTempDoc = objWord.Documents.Add objWord.Visible = False ' Position Word off the screen...this keeps Word invisible ' throughout. objWord.WindowState = 0 objWord.Top = -3000 ' Copy the contents of the textbox to the clipboard Clipboard.SetDataObject(text) ' With the temporary document, perform either a spell check or a ' complete ' grammar check, based on user selection. With objTempDoc .Content.Paste() .Activate() .Content.LanguageID = Word.WdLanguageID.wdFrenchCanadian If checkGrammar Then .CheckGrammar() Else .CheckSpelling() End If ' After user has made changes, use the clipboard to ' transfer the contents back to the text box .Content.Copy() iData = Clipboard.GetDataObject If iData.GetDataPresent(DataFormats.Text) Then text = CType(iData.GetData(DataFormats.Text), _ String) End If .Saved = True .Close() End With objWord.Quit() Return text End Function

Circular dependency with generics

- by devoured elysium

I have defined the following interface: public interface IStateSpace<State, Action> where State : IState where Action : IAction<State, Action> // <-- this is the line that bothers me { void SetValueAt(State state, Action action); Action GetValueAt(State state); } Basically, an IStateSpace interface should be something like a chess board, and in each position of the chess board you have a set of possible movements to do. Those movements here are called IActions. I have defined this interface this way so I can accommodate for different implementations: I can then define concrete classes that implement 2D matrix, 3D matrix, graphs, etc. public interface IAction<State, Action> { IStateSpace<State, Action> StateSpace { get; } } An IAction, would be to move up(this is, if in (2, 2) move to (2, 1)), move down, etc. Now, I'll want that each action has access to a StateSpace so it can do some checking logic. Is this implementation correct? Or is this a bad case of a circular dependence? If yes, how to accomplish "the same" in a different way? Thanks

imageconvolution leaves black dot in the upper left corner

- by Peter O.

I'm trying to sharp resized images using this code: imageconvolution($imageResource, array( array( -1, -1, -1 ), array( -1, 16, -1 ), array( -1, -1, -1 ), ), 8, 0); When the transparent PNG image is sharpened, using code above, it appears with a black dot in the upper left corner (I have tried different convolution kernels, but the result is the same). After resizing the image looked OK. 1st image is the original one 2nd image is the sharpened one EDIT: What am I going wrong? I'm using the color retrieved from pixel. $color = imagecolorat($imageResource, 0, 0); imageconvolution($imageResource, array( array( -1, -1, -1 ), array( -1, 16, -1 ), array( -1, -1, -1 ), ), 8, 0); imagesetpixel($imageResource, 0, 0, $color); Is imagecolorat the right function? Or is the position correct? EDIT2: I have changed coordinates, but still no luck. I've check the transparency given by imagecolorat (according to this post). This is the dump: array(4) { red => 0 green => 0 blue => 0 alpha => 127 } Alpha 127 = 100% transparent. Those zeroes might cause the problem...

Stop image from tiling

- by Glen Morse

I have a procedure: procedure DrawSolidHexImage(Target: TCanvas; { Canvas to draw hex on } Fillstyle : TBrushStyle; { How to fill the hex } Fillcolor : TColor; { Color to fill it } fillimage : Tbitmap; { Image to show} Linestyle : TPenStyle; { What kind of lines } LineColor : Tcolor; { What color for lines } x,y,radius: integer; { Position and size of Hex } button : boolean); { Make hexes look like buttons? } When I use this, the image is tiled to fill the area. Is there something I can add or must remove to make it not tile? Thus not repeating the image. Maybe make it center? The Code in which I use DrawSolidHexImage looks like: procedure THexMap.ImageAHex(ImageWanted : TBitmap; HexPatternWanted: TBrushStyle; MapLocation:TPoint); var p0:TPoint; begin if FHexMapOn and FDrawSolidMap and (not UseSavedMap) then begin with TempMap.canvas do p0 := ConvertCoords(Point(MapLocation.x,MapLocation.y),ptROWCOL); DrawSolidHexImage(TempMap.Canvas,HexPatternWanted,clGray, Imagewanted,psSolid,LineColor,p0.x,p0.y,hexradius,hex3d); Refresh; end; end;

If you look at the screenshot below you can see that the right menu box in red has the wrong position in IE6 and 7: <div id="doc4" class="yui-t2"> //yui-t2 = 180px on the left <div id="bd"> <div id="yui-main"> <div class="yui-b"> <div class="yui-gc"> // yui-gc 2/3, 1/3 <div class="yui-u first">content</div> // 2/3 <div class="yui-u">right menu</div> // 1/3 </div> </div> </div> <div class="yui-b">left menu</div> // 180px </div> <div id="ft">footer</div> </div> Anyone know how I can fix this problem?

Developing Job References

- by Joe Smith

How do you develop references for jobs? I have 6 years of programming experience spanning two jobs, but sadly I don't have a lot of people I can draw on as references. It's been several years since I left my last job, which was at a small company, and I've lost touch with the few people I knew there. I now work at another small company. I think I've gone as far as I can in my current position, and would like to look for greener pastures, but I can't exactly use my current boss as a reference, even though I have a very good repore with him. I'm sure he'd make a great reference down the road, but I'm afraid I'd insult him or jeopardize my current job by mentioning that I'm thinking of leaving and would like him to help me. I've applied to some jobs, and I have gotten several replies like, "Oh, you're exactly what we're looking for. Send us a couple references and we'll schedule an interview. Oh, no references? You must be a psychopath, nevermind." I've tried doing some small freelance work on the side, just so I can have a contact who can vouch for my work, but the competition for even small projects is pretty fierce and I can rarely devote adequate time to freelancing while holding a full time job. In addition, I often encounter a Catch-22 where a lot of freelancing jobs also require references. So how do programmers maintain existing references and develop new ones, especially while holding a full time job?

string maniupulations, oops, how do I replace parts of a string

- by Joe Gibson

I am very new to python. Could someone explain how I can manipulate a string like this? This function receives three inputs: complete_fmla: has a string with digits and symbols but has no hyphens ('-') nor spaces. partial_fmla: has a combination of hyphens and possibly some digits or symbols, where the digits and symbols that are in it (other than hyphens) are in the same position as in the complete_formula. symbol: one character The output that should be returned is: If the symbol is not in the complete formula, or if the symbol is already in the partial formula, the function should return the same formula as the input partial_formula. If the symbol is in the complete_formula and not in the partial formula, the function should return the partial_formula with the symbol substituting the hyphens in the positions where the symbol is, in all the occurrences of symbol in the complete_formula. For example: generate_next_fmla (‘abcdeeaa’, ‘- - - - - - - - ’, ‘d’) should return ‘- - - d - - - -’ generate_next_fmla (‘abcdeeaa’, ‘- - - d - - - - ’, ‘e’) should return ‘- - - d e e - -’ generate_next_fmla (‘abcdeeaa’, ‘- - - d e e - - ’, ‘a’) should return ‘a - - d e e a a’ Basically, I'm working with the definition: def generate_next_fmla (complete_fmla, partial_fmla, symbol): Do I turn them into lists? and then append? Also, should I find out the index number for the symbol in the complete_fmla so that I know where to append it in the string with hyphens??

Experience with Take home Programming Test for Interviews

- by Alan

Okay this is not "programming" related per-se, but it is a situation that I believe the SO audience would be more familiar with, than say an ask.yahoo.com audience, so please forgive me. I had a phone screen the other day with a company that I really want to work for. It went pretty well, based on cues from the HR person, such as "Next step we're going to send you a programming test," and "Well, before I get ahead of myself, do you want to continue the interviewing process." and "We'll send out the test later this afternoon. It doesn't sound like you'll have trouble with it, but I want to be honest we do have a high failure rate on it." The questions asked weren't technical, just going down my resume, and talking about the work I've done, and how it relates to the position. Nothing I couldn't talk through. This was last Thursday. It's now Tuesday, and haven't received the test yet. I sent a follow up email yesterday to the lady who interviewed me, but haven't gotten a response. Anyone had a similar experience? Am I reading too much into this? Or was I off the mark by thinking I had moved on to the next step in the interview process. Since this is a company I really want to work for, I'm driving myself insane enumerating all the various what-if scenarios.

Same font, character spacing and line-height but different results

- by Ben Huh

The introduction of @font-face in CSS3 allows web designers to use fonts that look the same across all browsers. That is what I thought until trying it out with the following code in jsFiddle: HTML: <div> The_Quick_Brown<br> Fox_Jumps_Over<br> The_Lazy_Dog </div> CSS: @font-face { font-family: 'Open Sans'; font-style: normal; font-weight: 400; src: url('http://themes.googleusercontent.com/static/fonts/opensans/v6/cJZKeOuBrn4kERxqtaUH3T8E0i7KZn-EPnyo3HZu7kw.woff') format('woff'); } div { display: block; width: 496px; height: 86px; font-size: 1.3em; font-family: 'Open Sans'; font-style: normal; margin: 0; border: 0; padding: 0; background: cyan; letter-spacing: 1.44em; line-height: 1.44; overflow: hidden; } This is the view from Firefox 12.0. Take note of the partially obscured 'o' in 'brown', the position of 'g' in 'dog' and the underscore '_' at the bottom edge. This is the view from Google Chrome 19.0. Despite explicitly setting letter-spacing and line-height for the same font, why are the results still different?

Dropping not working on Chrome Mac version

- by user600641

I tried to work with html5 drag&drop api, and it works very well on my chrome 20.0.1132 on windows machine, but most fun - that the same version of chrome on mac os lion is not working. I mean dragstart is working, but drop event, dragleave, dragover is not fired. Here is html: <form id="fake_form" action="#" > <div id="canvas_wrapper" style="overflow: hidden;width: 600px; position: relative;border: 1px solid black; margin-left: 30px;"> <canvas width="600" height="300" > </canvas> </div> </form> Here is javascript: var canvas = $('canvas')[0]; canvas.addEventListener('dragenter', function(e){ console.log('dragenter'); }, false); canvas.addEventListener('dragleave', function(){ console.log('dragleave'); }, false) canvas.addEventListener('dragover', function(e){ console.log('dragover'); if(e.preventDefault){ e.preventDefault(); } return false; }, false); canvas.ondrop = function(e){ console.log('ondrop'); /** OTHER CODE **/ If it helps: on safari on the same mac - it works, i`m dragging image tags some of them have draggable attribute, some of them - not. Just checked - on canary mac version 22 it works. UPDATE: i figured out that there is some magic with dragstart event, if i delete line with this e.dataTransfer.setData('src', src_var) everythings become working

AJAX AutoCompletExtender doesn't allow to move ahead of first item with arrow-key

Hi, I am using an AJAX AutoCompleteExtender to display a list of suburbs-postcodes after the user presses 3 keys in the given textbox. The problem is that on the page, I can't move my selection below the first item (with down arrow key/mouse). However with mouse if I click on any item, it gets selected. <asp:TextBox ID="txtPostalSuburb" runat="server" CssClass="select_insert_menu_text1" MaxLength="40" TabIndex="9"></asp:TextBox> <cc1:AutoCompleteExtender ID="txtPostalSuburb_AutoCompleteExtender" runat="server" DelimiterCharacters="" Enabled="True" ServicePath="~/Web/Common/ListingService.asmx" TargetControlID="txtPostalSuburb" UseContextKey="False" ServiceMethod="GetSuburbList" MinimumPrefixLength="3" CompletionListCssClass="contact-details-suggestion-list" OnClientItemSelected="AutoCompleteExtender_ItemSelected" CompletionListItemCssClass="contact-details-suggestion-list-item" > </cc1:AutoCompleteExtender> CSS: .contact-details-suggestion-list { background-color: window; color: windowtext; cursor: default; list-style-image: none; list-style-position: outside; list-style-type: none; padding:0px; text-align: left; border: solid 1px #005883; margin-top: 0px; font-size: 10px; } .contact-details-suggestion-list-item { border-bottom: dotted 1px black; } Any help is appreciated.

Interchange xsd and xsi in the output of XmlSerializer

- by Sri Kumar

XmlSerializer serializer = new XmlSerializer(typeof(IxComment)); System.IO.StringWriter aStream = new System.IO.StringWriter(); serializer.Serialize(aStream,Comments); commentsString = aStream.ToString(); Here the commentsString has the the following element in it <IxComment xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> Is there any possibility to interchange the xsi and xsd attribute and get the element as shown below <IxComment xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" > Will this cause any other issue? EDIT: Why do i need to do this? We are migrating an existing application from 1.1 to 3.0 and in the code there is a if loop int iStartTagIndex = strXMLString.IndexOf("<IxComment xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\">"); that check for the index of the IxComment. Here the o/p of the serializer and the condition differ in the position of xsd and xsi. So i am trying to know whether we can instruct the serializer to provided the o/p as required. I have another question here as this was an existing application does the serializer O/P differs with versions?

gluLookAt vectors and FPS-style camera

- by Kevin Pamplona

I am attempting to implemented an FPS-style camera by updating three vectors: EYE, DIR, UP. These vectors are the same that are used by gluLookAt (since gluLookAt is specified by the position of the camera, the direction it is looking at, and an up vector). I have already implemented the left-right and up-down strafing movements, but I'm having a lot of trouble understanding the math behind making the camera look-around while remaining stationary. In this case, the EYE vector remains the same, while I must update DIR and UP. Below is the code I tried, but it doesn't seem to work properly. Any suggestions? Thanks. void Transform::left(float degrees, vec3& dir, vec3& up) { vec3 axis; axis = glm::normalize(up); mat3 R = rotate(-degrees, axis); dir = R*dir; dir = R*up; }; void Transform::up(float degrees, vec3& dir, vec3& up) { vec3 axis; axis=glm::normalize(glm::cross(dir,up)); mat3 R = rotate(-degrees, axis); dir = R*dir-; up = R*up; };

array of structures, or structure of arrays?

- by Jason S

Hmmm. I have a table which is an array of structures I need to store in Java. The naive don't-worry-about-memory approach says do this: public class Record { final private int field1; final private int field2; final private long field3; /* constructor & accessors here */ } List<Record> records = new ArrayList<Record>(); If I end up using a large number ( 106 ) of records, where individual records are accessed occasionally, one at a time, how would I figure out how the preceding approach (an ArrayList) would compare with an optimized approach for storage costs: public class OptimizedRecordStore { final private int[] field1; final private int[] field2; final private long[] field3; Record getRecord(int i) { return new Record(field1[i],field2[i],field3[i]); } /* constructor and other accessors & methods */ } edit: assume the # of records is something that is changed infrequently or never I'm probably not going to use the OptimizedRecordStore approach, but I want to understand the storage cost issue so I can make that decision with confidence. obviously if I add/change the # of records in the OptimizedRecordStore approach above, I either have to replace the whole object with a new one, or remove the "final" keyword. kd304 brings up a good point that was in the back of my mind. In other situations similar to this, I need column access on the records, e.g. if field1 and field2 are "time" and "position", and it's important for me to get those values as an array for use with MATLAB, so I can graph/analyze them efficiently.

UnicodeEncodeError: 'ascii' codec can't encode character [...]

- by user1461135

I have read the HOWTO on Unicode from the official docs and a full, very detailed article as well. Still I don't get it why it throws me this error. Here is what I attempt: I open an XML file that contains chars out of ASCII range (but inside allowed XML range). I do that with cfg = codecs.open(filename, encoding='utf-8, mode='r') which runs fine. Looking at the string with repr() also shows me a unicode string. Now I go ahead and read that with parseString(cfg.read().encode('utf-8'). Of course, my XML file starts with this: <?xml version="1.0" encoding="utf-8"?>. Although I suppose it is not relevant, I also defined utf-8 for my python script, but since I am not writing unicode characters directly in it, this should not apply here. Same for the following line: from __future__ import unicode_literals which also is right at the beginning. Next thing I pass the generated Object to my own class where I read tags into variables like this: xmldata.getElementsByTagName(tagName)[0].firstChild.data and assign it to a variable in my class. Now what perfectly works are those commands (obj is an instance of the class): for element in obj: print element And this command does work as well: print obj.__repr__() I defined __iter__() to just yield every variable while __repr__() uses the typical printf stuff: "%s" % self.varname Both commands print perfectly and can output the unicode character. What does not work is this: print obj And now I am stuck because this throws the dreaded UnicodeEncodeError: 'ascii' codec can't encode character u'\xfc' in position 47: So what am I missing? What am I doing wrong? I am looking for a general solution, I always want to handle strings as unicode, just to avoid any possible errors and write a compatible program. Edit: I also defined this: def __str__(self): return self.__repr__() def __unicode__(self): return self.__repr__() From documentation I got that this

iTextSharp Overlay Image

- by pennylane

Hi guys I have an instance where I have a logo image as part of some artwork.. If a user uploads a new logo I have a form field which is larger than the default logo. I then use that form field to position the new image. The problem is I need to set the background colour of that form field to white so that it covers the old logo in the event that the new image is smaller than the old logo.. what I have done is: foreach (var imageField in imageReplacements) { fields.SetFieldProperty(imageField.Key, "bgcolor", iTextSharp.text.Color.WHITE, null); fields.RegenerateField(imageField.Key); PdfContentByte overContent = stamper.GetOverContent(imageField.Value.PageNumber); float[] logoArea = fields.GetFieldPositions(imageField.Key); if (logoArea != null) { iTextSharp.text.Rectangle logoRect = new iTextSharp.text.Rectangle(logoArea[1], logoArea[2], logoArea[3], logoArea[4]); var logo = iTextSharp.text.Image.GetInstance(imageField.Value.Location); if (logo.Width >= logoRect.Width || logo.Height >= logoRect.Height) { logo.ScaleToFit(logoRect.Width, logoRect.Height); } logo.Alignment = iTextSharp.text.Image.ALIGN_LEFT; logo.SetAbsolutePosition(logoRect.Left, logoArea[2] + (logoRect.Height - logo.ScaledHeight) / 2); // left: logoArea[3] - logo.ScaledWidth + (logoRect.Width - logo.ScaledWidth) / 2 overContent.AddImage(logo); } } The problem with this is that the background colour of the field is set to white and the image then doesn't appear.. i remove the SetFieldProperty and RegenerateField commands and the image replacement works fine.. is there a way to set a stacking order on layers?

IE7: container of hidden Div displays incorrectly

- by dmr

There is a search box div that contains a boxhead div and a boxbody div. Inside the boxbody div, there is a searchToggle div. When the user clicks a certain link on the page, the display style property of the searchToggle div is toggled between block and none. The 2 background-images for the body of the search box are set via the css of the searchBox div and the boxbody div. In IE7, when the searchToggle div is hidden, the background-image from the searchBox div extends on the left more than it should. It shows up correctly when the display of the searchToggle div is block. Everything show up correctly, in both cases in IE8 and FF. Any ideas why this is happening? The relevant HTML: <div class="searchBox"> <div class="boxhead"> <h2></h2> </div> <div class="boxbody"> <div id="searchToggle" name="searchToggle"> </div> </div> </div> The relevant CSS: .searchBox { margin: 0 auto; width: 700px; background: url(/images/myImageRight-r.gif) no-repeat bottom right; font-size: 100%; text-align: left; overflow: hidden; } .boxbody { margin: 0; padding: 5px 30px 31px; background-image: url(/images/myImageLeft.gif); background-repeat: no-repeat; background-position: left bottom; }

Random-access archive for Unix use

- by tylerl

I'm looking for a good format for archiving entire file-systems of old Linux computers. TAR.GZ The tar.gz format is great for archiving files with UNIX-style attributes, but since the compression is applied across the entire archive, the design precludes random-access. Instead, if you want to access a file at the end of the archive, you have to start at the beginning and decompress the whole file (which could be several hundred GB) up to the point where you find the entry you're looking for. ZIP Conversely, one selling point of the ZIP format is that it stores an index of the archive: filenames are stored separately with pointers to the location within the archive were to find the data. If I want to extract a file at the end, I look up the position of that file by name, seek to the location, and extract the data. However, it doesn't store file attributes such as ownership, permissions, symbolic links, etc. Other options? I've tried using squashfs, but it's not really designed for this purpose. The file format is not consistent between versions, and building the archive takes a lot of time and space. What other options might suit this purpose better?

Why can't I display a unicode character in the Python Interpreter on Mac OS X Terminal.app?

- by apphacker

If I try to paste a unicode character such as the middle dot: · in my python interpreter it does nothing. I'm using Terminal.app on Mac OS X and when I'm simply in in bash I have no trouble: :~$ · But in the interpreter: :~$ python Python 2.6.1 (r261:67515, Feb 11 2010, 00:51:29) [GCC 4.2.1 (Apple Inc. build 5646)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> ^^ I get nothing, it just ignores that I just pasted the character. If I use the escape \xNN\xNN representation of the middle dot '\xc2\xb7', and try to convert to unicode, trying to show the dot causes the interpreter to throw an error: >>> unicode('\xc2\xb7') Traceback (most recent call last): File "<stdin>", line 1, in <module> UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position 0: ordinal not in range(128) I have setup 'utf-8' as my default encoding in sitecustomize.py so: >>> sys.getdefaultencoding() 'utf-8' What gives? It's not the Terminal. It's not Python, what am I doing wrong?! This question is not related to this question, as that indivdiual is able to paste unicode into his Terminal.

How to prevent chrome from injecting content to webpage

- by Nazariy

Recently I have discovered that my application is misbehaving in Google Chrome. On a page with a form, after it was submitted, my application reloads page using simple method like this: header('Location: ' . $url); after that, page is rendered incorrectly and this content is injected to DOM <div id="sbi_camera_button" class="sbi_search" style="left: 0px; top: 0px; position: absolute; width: 29px; height: 27px; border: none; margin: 0px; padding: 0px; z-index: 2147483647; display: none; "></div> After manual page refresh everything works as expected. I'm not sure what causing this behavior, as I'm working in closed local environment and application works fine in Firefox. My application using following libraries (hosted locally): jQuery v1.7.1 jQuery UI 1.8.16 Bootstrap.js v 2.1.1 Can someone suggest me what can possibly cause this issue?
