• Strange jboss console error

  - by c0mrade

  Hello everyone, I'm creating additional module to already multi-module maven project. And for this one I want everything to be like in other modules(meaning dependencies) just to test hello world, then I'll go do some more complex stuff. And it does print hello world as it should when deployed onto jboss server, but I get some strange error on console, had anyone had similar experience? and how can I fix it? Here it is : 15:48:35,789 ERROR [STDERR] log4j:ERROR A "org.jboss.logging.appender.FileAppender" object is not assignable to a "org.apache.log4j.Appender" variable. 15:48:35,789 ERROR [STDERR] log4j:ERROR The class "org.apache.log4j.Appender" was loaded by 15:48:35,790 ERROR [STDERR] log4j:ERROR [BaseClassLoader@9a8d9b{vfszip:/C:/jboss-5.1.0.GA/server/default/deploy/new-module-0.0.1-SNAPSHOT.war/}] whereas object of type 15:48:35,790 ERROR [STDERR] log4j:ERROR "org.jboss.logging.appender.FileAppender" was loaded by [org.jboss.bootstrap.NoAnnotationURLClassLoader@506411]. 15:48:35,790 ERROR [STDERR] log4j:ERROR Could not instantiate appender named "FILE".

• Ruby on Rails: strange voting increment behavior

  - by Justin Meltzer

  So I have an up and a downvote button that inserts a vote with a value of 1 or -1 into the database. This works correctly. Then, I display the total vote count for that element by summing up its votes' values. However, this isn't working correctly, because the vote sum display is acting really strange: The first vote on a video doesn't seem to increment it at all. Then the second vote does. If I go from an upvote to a downvote, it increments up once, and then the next downvote is down. This is difficult to explain, but maybe you can figure out what is wrong with my code. I have this function in my Video model (the element that is voted on, it has_many video_votes): def vote_sum read_attribute(:vote_sum) || video_votes.sum(:value) end I also have this in my VideoVote model: after_create :update_vote_sum private def update_vote_sum video.update_attributes(:vote_sum => video.vote_sum + value) end What am I doing wrong?

  - by Roland Soós

  Hello, I have a really strange bug with my PHP code. I have a recursive code which build up a menu tree with object and one of my customers server can't make it work.

  - by celalo

  Hello, I have a application server for network operations written with JAVA based on Apache Mina. Recently I encounter a strange behavior in my log files. I noticed that the log file is full of @^@^@^@^@^@^@^@^@^@^@^@^.... characters. I mean those unexpected characters are vast amount of as such the log file gets hundreds of GB in a couple of hours! I have no clue about this problem and it is almost impossible to google it. What could be the reason? Are those set of characters any familiar to anybody? I can give more details about the application if needed. Thanks in advance.

• Strange Scala error.

  - by Lukasz Lew

  I tried to create abstract turn based Game and abstract AI: abstract class AGame { type Player type Move // Player inside def actPlayer : Player def moves (player : Player) : Iterator[Move] def play (move : Move) def undo () def isFinished : Boolean def result (player : Player) : Double } abstract class Ai[Game <: AGame] { def genMove (player : Game#Player) : Game#Move } class DummyGame extends AGame { type Player = Unit type Move = Unit def moves (player : Player) = new Iterator[Move] { def hasNext = false def next = throw new Exception ("asd") } def actPlayer = () def play (move : Move) { } def undo () { } def isFinished = true def result (player : Player) = 0 } class DummyAi[Game <: AGame] (game : Game) extends Ai[Game] { override def genMove (player : Game#Player) : Game#Move = { game.moves (player).next } } I thought that I have to use this strange type accessors like Game#Player. I get very puzzling error. I would like to understand it: [error] /home/lew/Devel/CGSearch/src/main/scala/Main.scala:41: type mismatch; [error] found : Game#Player [error] required: DummyAi.this.game.Player [error] game.moves (player).next [error] ^

• Strange fstream problem

  Hi, I have really strange problem. In Visual C++ express, I have very simple code, just: #include <fstream> using namespace std; int main() { fstream file; file.open("test.txt"); file<<"Hello"; file.close(); } This same code works OK in my one project, but when I create now project and use this same lines of code, no file test.txt is created.

• Strange padding in Safari when using SVG images

  - by Naman Goel

  I thought I was having issues with margins but then on a closer look I found that SVGs are acting funky in Safari 6. I am building a simple Hexagon based website. Of course I used negative vertical margins to for a little overlap to 'inter-lock' the hexagons. And to save space I was using SVG images for the hexagons. It works great in chrome and firefox, but in Safari, there is a strange padding in the SVG images. I'm using simple img tags for the svg images. Everything works when I switch to PNG, but I'd prefer to stick to SVGs. Any insight? Can I perhaps delve into the SVG code and somehow fix the SVG problem in Safari? or is it some sort of bug, that I can do nothing about without browser sniffing?

• Getting strange response on calling verifyReceipt to verify an in-app

  - by lostInTransit

  Hi I am making a call to verifyReceipt to validate an in-app purchase but am getting a very strange response (the response is b) The same code worked till some time back. But I stopped the app debugging while the trans was being verified at one point. From there on, the only response I get is b. I checked the code and it has nothing wrong. As I said, the same code worked till I stopped this trans mid-way. Any idea what could be wrong? Thanks.

• Strange/simple batch question regarding Java/Ant

  - by Monster

  For my company, I'm making a batch script to go through and compile the latest revisions of code for our current project. I'm using Ant to build the class files, but encountered a strange error. One of the source files imports .* from a directory, where there are no files (only folders), and in fact, the folders needed are imported right after. It compiles perfectly fine in Eclipse, but I'm using an Ant script to automate it outside of the IDE, and Javac throws an error when it encounters this line. Is there any automated procedure I can use to ignore/suppress this error with javac in Ant? I'd even go so far as to create a dummy file in the importing directory, but all of that in contained in a Jar file I don't wish to have to decompress and then recompress with the dummy file. Thanks!

• Strange execution of get accesor in c#?

  - by Kenji Kina

  I set up a simple program just to test how the code inside a get accessor executes (since I had been having some issues in another project), and found something quite strange: class Program { static void Main(string[] args) { var test = new TestClass(); var testBool = test.TestBool; } } public class TestClass { private bool _testBool = true; public bool TestBool { get { if (_testBool) { Console.WriteLine("true!"); } else { Console.WriteLine("false! WTF!"); } _testBool = false; return _testBool; } } } I expected the output to be true! But what I got instead was true! false! WTF! Just what is going on here?

• Strange profiling results: definitely non-bottleneck method pops up

  - by jkff

  I'm profiling a program using sampling profiling in YourKit and JProfiler, and also "manually" (I launch it and press Ctrl-Break several times to get thread dumps). All three methods give me extremely strange results: some tens of percents of time spent in a 3-line method that does not even do any allocation or synchronization and doesn't have loops etc. Moreover, after I made this method into a NOP and even removed its invocation completely, the observable program performance didn't change at all (although it got a negligible memory leak, since it was a method for freeing a cheap resource). I'm thinking that this might be because of the constraints that JVM puts on the moments at which a thread's stacktrace may be taken, and it somehow turns out that in my program it is exactly the moments where this method is invoked, although there is absolutely nothing special about it or the context in which it is invoked. What can be the explanation for this phenomenon? What are the aforementioned constraints? What further measurements can I take to clarify the situation?

• Strange behavior: Dynamic expressions with RegExp Object in RegExp.match (Javascript)

  - by NeDark

  I have detect a strange behavior in regexps created with the RegExp object: With this code: var exp1 = /./; var exp2 = new RegExp('.'); ? var test1 = exp1.test('large\n\ntext..etc.'); var test2 = exp2.test('large\n\ntext..etc.'); ? var match1 = 'large\n\ntext..etc.'.match(exp1); var match2 = 'large\n\ntext..etc.'.match(exp2); ...the result is: test1 = true test2 = true ? match1 = 'l' (first match) match2 = null With the regexp maked with the regexp object from a string it finds nothing... Why does this happends? Thanks!!

• Python beginner, strange output problem

  - by Protean

  I'm having a weird problem with the following piece of code. from math import sqrt def Permute(array): result1 = [] result2 = [] if len(array) <= 1: return array for subarray in Permute(array[1:]): for i in range(len(array)): temp1 = subarray[:i]+array[0]+subarray[i:] temp2 = [0] for num in range(len(array)-1): temp2[0] += (sqrt(pow((temp1[num+1][1][0]-temp1[num][1][0]),2) + pow((temp1[num+1][1][1]-temp1[num][1][1]),2))) result1.append(temp1+temp2) return result1 a = [['A',[50,1]]] b = [['B',[1,1]]] c = [['C',[100,1]]] array = [a,b,c] result1 = Permute(array) for i in range(len(result1)): print (result1[i]) print (len(result1)) What it does is find all the permutations of the points abc and then returns them along with the sum of the distances between each ordered point. It does this; however, it also seems to report a strange additional value, 99. I figure that the 99 is coming from the computation of the distance between point a and c but I don't understand why it is appearing in the final output as it does.

• Blackberry Widget Packager saves my files in strange places

  - by chibineku

  I have just installed the Blackberry Widget Packager and Blackberry Web Plug-In for Eclipse, and everything works fine, but my files are output to strange places. For example, I tried putting my zipped source files in the folder Blackberry Widget Packager/web and I got an error during packaging. Packaging works when the .zip is in the same directory as wwbp, though. When a widget is successfully created, the executable .jar file and the .rapc files are put in some stupid folder like users/user/temp/widgetname094098456, and the other files are split between two folders in Blackberry Widget Packager/bin. This is slightly annoying as I don't want to be spending time herding my files. Anyone have any thoughts on why my files are being scattered like this?

• Strange findFn malfunction

  - by gd047

  I noticed a strange malfunction in using findFn function (library sos) and I can't find out the source. While it works fine on my Windows XP pc, it does not on my Vista one. library (sos) findFn("randomization test") # in both finds 72 results findFn("{randomization test}") # In XP finds 19 or about so, but in Vista whenever I use {} and more than one word inside, # I keep getting the following: found 0 matches x has zero rows; nothing to display. Warning message: In findFn("{randomization test}") : HIT not found in HTML; processing one page only. R ver = 2.10.1 and packages updated. Any ideas where the problem might be? Bonus: As it's obvious, I was looking for functions about tests for randomized experiments

• Strange Error - "Object moved to here."

  I get the strange error "Object moved to here." on a blank white page when I try to login on a site I created. It works fine locally but not when I deploy it to the test or production server. I am not doing anything odd, just using basic authentication code in a helper function as follows... public static bool AuthenticateUser(string Username, string Password, bool PersistLogin, string RedirectionURL) { if (Membership.ValidateUser(Username, Password)) { FormsAuthentication.SetAuthCookie(Username, PersistLogin); HttpContext.Current.Response.Redirect(RedirectionURL,true); return true; } else return false; }

• Strange problem when converting RGB to HSV

  - by zaplec

  Hi, I made a small RGB to HSV converter algorithm with C. It seems to work pretty well, but there is one strange problem: If I first convert i.e. a 800x600 picture into HSV map and then back to RGB map without doing any changes in the values, I get some pixels that are convertet incorrectly. Then if I try to convert those misbehaving single pixels alone to and back, they're converted correctly. Any idea what could be the problem? I'm using Daniel Karlings PNGLite to open that PNG file. Here are the source code of my main.c, rgbtohsv.c and rgbtohsv.h rgbToHsv.h rgbToHsv.c pngmain.c I linked pngmain only that if somebody wants to test and run this on his own system. -zaplec

• HTML/Javascript Strange behavior with input field and TABBING

  - by Berlin Brown

  I have a strange error where if a user enters in data, say first name and then tabs, the text in the field is highlighted/selected as opposed to moving to the next. So, a person may type the first name and then tab to the next input item, text is selected and then they hit a character and now the name they typed in is deleted. If I use the default [input] tags, the tab works properly. But in the code below, with keyup, that may change the tabbing behavior. How can I get my code where it won't select the text. This is replicated in Firefox and Internet Explorer. function enableSearch(lnameObj) { var goButtonObj = document.getElementById('goButton'); var nextButtonObj = document.getElementById('nextButton'); var lastName = lnameObj.value; if (lastName == "") { goButtonObj.disabled = true; } else { goButtonObj.disabled = false; } } <input type="text" size="12" name="lastname" onKeyUp="return enableSearch(this);" value="">

• Array.Copy: strange exception while concatenating two byte arrays

  - by robob

  In a application of mine that is developed in C# I have the following code: byte[] resb = new byte[Buffer.ByteLength(blockAr) + Buffer.ByteLength(previous)]; Array.Copy(blockAr, 0, resb,0, blockAr.Length); Array.Copy(previous, 0, resb, blockAr.Length, previous.Length); It's a very simple code to concatenate two byte arrays. The problem is that in some particular situation that I don't know I have that exception: ArgumentOutOfRangeException: sourceIndex is less than the lower bound of the first dimension of sourceArray. I cannot see any of strange in my code and I am not able to reproduce the exception. Could anyone help me to identify the problem? thanks

• Strange problem with ie6 messing up layout, and fixing byitself some time after loading

  - by 0al0

  We have a big ie6 layout problem with a newly launched website: in the header in our homepage, we have a coda-slider, and apparently its messing upt the wole layout of the front page. I have been looking at float and height problems but cannot seem to solve it. Also, the most strange part is that if you wait a while after loading, the layout "fixes itself". Help! The url is the following (without the spaces, sorry) w w w . r e - c r e a r t . c o m Edit: update, it sounds crazy, but if you press control and use the mouse wheel (as if you were zooming in /out in a modern browser, although ie6 doesnt do that) the layout fixes as well. Please help, I am going crazy.

• c++: strange syntax in what() method of std::exception

  - by Patrick Oscity

  When i am inheriting from std::exception in order to define my own exception type, i need to override the what() method, which has the following signature: virtual const char* what() const throw(); This definitely looks strange to me, like if there were two method names in the signature. Is this some very specific syntax, like with pure virtual methods, e.g.: virtual int method() const = 0; or is this a feature, that could somehow be used in another context, too? And if so, for what could it be used?

• Strange calculation problem in C multiply by 1.2 fails

  - by DoomStone

  I have this c code, where i need to calculate a dobule from a long. double result; long t2_value; t2_value = 72; result = t2_value * 1.2; Now this code crashes at "result = t2_value * 1.2;" only with the error "Vector 0000000006". Here is the strange thing, if i replace result = t2_value * 1.2; with result = 72 * 1.2; evything works just as it should, i have tryed type casting t2_value as an double result = ((double)t2_value * 1.2); or making it an int istead of a long, but nothing helps.
