• MyFaces Test Framework not working with JSF 2.1

  - by Karl Kildén

  we have a lot of tests that uses Myfaces Test Framework for JSF 2.0. http://myfaces.apache.org/test/index.html Problem is we can't get it to work with JSF 2.1. Does anyone know a workaround or a way to solve this? When we run the tests we get the following error: java.lang.IllegalStateException: Application was not properly initialized at startup, could not find Factory: javax.faces.application.ApplicationFactory It works fine with jsf 2.0 though. A typical use case in our code: // code block; assertFalse("Error message not expected. ", facesContext .getMessages().hasNext()); JSF 2.1 has a few syntax changes so my guess would be that's the problem.

• Debug.Assert seems not to work in Mono

  - by Jan-Willem

  Consider the following C# program: using System; using System.Diagnostics; namespace Test { class MainClass { public static void Main (string[] args) { Debug.Assert(false); Debug.Fail("fail!"); Console.WriteLine ("Hello World!"); } } } When compiling this using: dmcs -debug -d:DEBUG Main.cs and then running it with: mono --debug Main.exe the assertion and fail seem to be ignored. The output is just: Hello World! I checked other related questions on StackOverflow, but I could not find a solution. In particular the solution give in Mono - Debug.Assert does not work does not work. (UPDATE: the update solution does work, see below comments.) I use Mono 2.1.5-1 on Ubuntu 11.10.

• IE - hidden radio button not checked when the corresponding label is clicked

  - by ScottE

  I just noticed a strange behaviour in IE7. I have radio buttons with associated labels as follows: <input type="radio" name="filter" id="filter_1" value="Activities" checked="checked" /> <label for="filter_1">Activities</label> <input type="radio" name="filter" id="filter_2" value="Services" /> <label for="filter_2">Services</label> The radio button is hidden via css with display:none or visibility: hidden (don't ask) The problem is - when I click the label in IE7 (haven't looked at other IE versions yet) the associated radio button is not actually checked. I confirmed this with jquery - the label click event is fired, but the radio button click event is not. A form post also confirms that the checked radio button does not change. This works correctly in firefox, and also works correctly if I remove the CSS that hides the radio buttons. Is this an IE bug or am I missing something?

• What is the reason not to use select * ?

  - by Chris Lively

  I've seen a number of people claim that you should specifically name each column you want in your select query. Assuming I'm going to use all of the columns anyway, why would I not use SELECT *? Even considering the question from 9/24, I don't think this is an exact duplicate as I'm approaching the issue from a slightly different perspective. One of our principles is to not optimize before it's time. With that in mind, it seems like using SELECT * should be the preferred method until it is proven to be a resource issue or the schema is pretty much set in stone. Which, as we know, won't occur until development is completely done. That said, is there an overriding issue to not use SELECT *?

• Django template context not working with imported class

  - by Andy Hume

  I'm using Django's templating on appengine, and am having a problem whereby a class I'm importing from another package is not correctly being made available to the template context. Broadly speaking, this is the code. The prop1 is not available in the template in the first example below, but is in the second. MyClass is identical in both cases. This does not work: from module import MyClass context = MyClass() self.response.out.write(template.render(path, context)) This does: class MyClass(object): def __init__(self): self.prop1 = "prop1" context = MyClass() self.response.out.write(template.render(path, context)) If I log the context in the above code I get: <module.MyClass object at 0x107b1e450> when it's imported, and: <__main__.MyClass object at 0x103759390> when it's defined in the same file. Any clues as to what might cause this kind of behaviour?

• Regular expression for a string containing one word but not another

  - by Chris Stahl

  I'm setting up some goals in Google Analytics and could use a little regex help. Lets say I have 4 URLs http://www.anydotcom.com/test/search.cfm?metric=blah&selector=size&value=1 http://www.anydotcom.com/test/search.cfm?metric=blah2&selector=style&value=1 http://www.anydotcom.com/test/search.cfm?metric=blah3&selector=size&value=1 http://www.anydotcom.com/test/details.cfm?metric=blah&selector=size&value=1 I want to create an expression that will identify any URL that contains the string selector=size but does NOT contain details.cfm I know that to find a string that does NOT contain another string I can use this expression: (^((?!details.cfm).)*$) But, I'm not sure how to add in the selector=size portion. Any help would be greatly appreciated!

• File.Exists() returns false, but not in debug

  - by Tor Haugen

  I'm being completely confused here folks, My code throws an exception because File.Exists() returns false public override sealed TCargo ReadFile(string fileName) { if (!File.Exists(fileName)) { throw new ArgumentException("Provided file name does not exist", "fileName"); } Visual studio breaks at the throw statement, and I immediately check the value of File.Exists(fileName) in the immediate window. It returns true. When I drag the breakpoint back up to the if statement and execute it again, it throws again. fileName is an absolute path to a file. I'm not creating the file, nor writing to it (it's there all along). If I paste the path into the open dialog in Notepad, it reads the file without problems. The code is executing in a background worker. It's the only complicating factor I can think of. I am positive the file has not been opened already, either in the worker thread or elsewhere. What's going on here?

• Preprocessor not skipping asm directives

  - by demula

  I'm programming to a microprocessor (Coldfire) and I don't have access every day to the microprocessor trainer so I want to be able to execute some of my code on the computer. So I'm trying to skip a part of my code when executing on the computer by defining _TEST_. It doesn't work. It tries to compile the asm code and dies whining about not knowing the registers names (they're defined alright compiling against the Coldfire, not my Intel Core Duo). Any ideas why it's not working? or maybe an alternative way to run the code on the pc without commenting it out?. Here's sample code from my project: inline void ct_sistem_exit(int status) { #ifdef _TEST_ exit(status); #else asm volatile( "moveb #0,%%d1\n\t" "movel #0, %%d0\n\t" "trap #15\n\t" : : : "d0", "d1" ); #endif /* _TEST_ */ } If it helps: using gcc3 with cygwin on Netbeans 6.8

• python open does not create file if it doesnt exist

  - by Toddeman

  I am using Python. What is the best way to open a file in rw if it exists, or if it does not, then create it and open it in rw? From what i read, file = open('myfile.dat', 'rw') should do this, no? it is not working for me (python 2.6.2) and im wondering if it is a version problem, or not supposed to work like that or what. The bottom line is, i just need a solution for the problem. I am curious about the other stuff, but all i need is a nice way to do the opening part. thanks in advance

• How to make Amazon EC2 not cause SSL invalid error in browser

  - by tadatoshi

  I use SSL certificate for a web site I set up in Amazon EC2 Machine Instance. The SSL certificate is for one domain name, which is not public DNS for the Amazon Machine Instance. The browser always complains the mismatch in the domain name because it compares the domain name of the SSL certificate to the Amazon public DNS. How can I set up not to cause this problem? I tried both domain name forwarding and A Record setting. Maybe it's because I'm not so familiar with Amazon EC2 and I haven't configured domain name correctly. Any help will be greatly appreciated.

• Magento module - database not initialized?

  - by Magnus

  Hello, So I've installed an extension in my Magento Enterprise. I've been able to configure new options in the admin interface after installing the module. However in the frontend it complains "table not found". Checking the database that is indeed true. Seems the mysql4-*.php scripts have not been run or failed. Is there a log or something I can look at to see what goes wrong? From what I've read (difficult to find documentation on this) the modules db should've been initialized on the first request after it was installed and activated. Any other suggestions to what I can check to find out why it's not initialized properly?

• Why are Asynchronous processes not called Synchronous?

  - by Balk

  So I'm a little confused by this terminology. Everyone refers to "Asynchronous" computing as running different processes on seperate threads, which gives the illusion that these processes are running at the same time. This is not the definition of the word asynchronous. a·syn·chro·nous –adjective 1. not occurring at the same time. 2. (of a computer or other electrical machine) having each operation started only after the preceding operation is completed. What am I not understanding here?

• using dummy row with NOT NULL to solve DEFAUT NULL

  - by Tony38

  I know having DEFAULT NULLS is not a good practice but I have many optional lookup values which are FK in the system so to solve this issue here is what i am doing: I use NOT NULL for every FK / lookup valve field. I have the first row in every table which is PK id = 1 as a dummy row with just "none" in all the columns. this way I can use NOT NULL in my schema and if needed reference to the none row values which should be null. Is this a good design or any other work arounds?

• mootools: $ not defined

  - by eaigner

  I've strange error i don't understand. I'm just moving my code from jQuery over to Mootools because it's much cleaner than the jQuery mess. Now when i use the $$('div.canvas') in mootools i get the correct element. When i try $(document).getElement('div.canvas') it tells me that $ is not defined. How can $$ and all helper functions like $lambda etc. be defined but not $? Has something changed there from 1.1 to 1.2 and the docs are not updated yet?

• Displaying objects based on if a user is logged in or not

  - by MaxMackie

  I'm learning about PHP sessions for user authentication on my website. I know how to restrict the viewing of a complete page using sessions (simply check if the 'uid' session variable is set and if it is, show content, if not redirect to an error). However I'm trying to figure out the best way to selectively show and hide different objects (div, text, images) based on if a user is logged in or not. Is it as simple as checking for the 'uid' session variable and displaying based on if it set or not? Is there a more efficient way of doing this id there are a lot of conditional elements on a page?

• Function defined but not used warning in C

  - by thetna

  I have a number of C source files(both .c and .h files). header files contains a number of functions. Out of those functions, only partially are used in a source .C file.Suppose a.h,b.h are header files and a.c and b.c are .c files. a.h is included in a.c. But only a number of functions those are in a. h are used and rest are not used. After compilation I find following warnings: function XXXX defined but not used. But those XXXX functions which are not used in a.c are used in b.c. So, i can't completely remove those functions too. So , i decided to make a separate file containing only those XXXX functions and included it wherever it is used.Doing this is creating multiple number of header files. Can anybody please suggest me to some effective way to solve this problem.

• Failing faster when URL content is not found, howto

  I have a thread pool that loops over a bunch of pages and checks to see if some string is there or not.

Dragging it to the middle or right green area, I can not drag the element. I increment the zIndex of the elements, but it does not work. Does anyone can help me, what's wrong? Best Regards.

I want to find something like the shopping cart at the apple store, it's a div thats not positioned absolute nor fixed, for instance, let's say it's at the center of the screen, and only when you scroll down it follows the scroll only to not disappear, when it reaches the border of the browser header... I'm not sure If i'm being clear. I've searched but all I found is the css position fixed stuff. Can you help me with a link or something? Best Regards

• twisted .loseConnection does not immediately lose connection?

  - by Claudiu

  I have a server with a few clients connected to it. When CTRL+C is hit (that is, reactor starts shutting down), I want to close all my connections, wait until they are cleanly closed, and then stop. I do this by going through the connected clients' transports and calling .loseConnection(). On the ones that are connected locally, they immediately disconnect. However, on one that is connected through the internet, the connection is not immediately lost. Communication stops - and closing the client program no longer even tells the server that the connection has died, although it does before calling .loseConnection() - but the connection is not deemed 'lost' until a few minutes later after I send a few heartbeat requests from the server. I understand that if a connection dies, there's no way for the server to know unless it tries to send some data. But if I specifically ask for a connection to be closed, why does it not just close/disconnect immediately? Am I calling the wrong function?

• Create a javascript chome extention that does not execute in 6 months

  - by user1907657

  I have just started learning programming and I would like to make a script into a chrome extension. Its a basic script and I hope to practice more and more and develop bigger projects and set myself bigger tasks This script has to do the following : reload a page every 20 seconds (say google.com) after 6 months the script must not run (maybe prompt a window saying "its over 6 months") The code should be able to go into a small chrome extension and also the 6 month time period should be absolute not relative to the time the script was started; for example should the browser crash and i have to turn on the extension again it should not restart the 6 month counter. Also if anyone could recommend any good sources for JavaScript to learn (preferably books; nothingIi read online ever seems to stick)
