  • Why do encodeXxx methods in UIComponent accept FacesContext parameter?

    - by Roman
    I haven't ever before created custom components in JSF so I've noticed only now that methods like encodeBegin(), encodeEnd() etc accept FacesContext parameter. FacesContext instance can usually be received with FacesContext.getCurrentInstance(). So, I wonder whether these methods have FacesContext parameter just for convenience or some different objects can be passed there (maybe from external resources..). If the latter is possible then could you give an example pls.

  • How to deal with JSON output that might be an array, or might be a value

    - by Summer
    Hi - I'm getting JSON-encoded output from another organization's API. In many cases, the output can be either an array of objects (if there are many) or an object (if there's just one). Right now I'm writing tortured code like this: if ( is_array($json['candidateList']['candidate'][0]) ) { foreach ($json['candidateList']['candidate'] as $candidate) { // do something to each object } } else { // do something to the single object } How can I handle it so the "do something" part of my code only appears once and uses a standard syntax?

  • Is it possible to use multiple languages in .NET resource files?

    - by Gabe Brown
    We’ve got an interesting requirement that we’ll want to support multiple languages at runtime since we’re a service. If a user talks to us using Japanese or English, we’ll want to respond in the appropriate language. FxCop likes us to store our strings in resource files, but I was curious to know if there was an integrated way to select resource string at runtime without having to do it manually. Bottom Line: We need to be able to support multiple languages in a single binary. :)

  • Is there a good .Net CSS aggregator that combines style sheets and minifies them?

    - by vfilby
    I am looking to see if there is an open source/free project that provides a CSS manager. I am looking for this mainly for performance tweaking and hoping there is a readymade project rather than building from scratch. Features I am looking for include: Combines multiple .css files into a single css file Optionally minifies the resulting .css file Works well with .Net (a user control, custom handler, etc) Is there a project out that that handles this?

  • Injection of class with multiple constructors

    - by Jax
    Resolving a class that has multiple constructors with NInject doesn't seem to work. public class Class1 : IClass { public Class1(int param) {...} public Class1(int param2, string param3) { .. } } the following doesn’t seem to work: IClass1 instance = IocContainer.Get<IClass>(With.Parameters.ConstructorArgument(“param”, 1)); The hook in the module is simple, and worked before I added the extra constructor: Bind().To(); Thanks in advance...

  • rails multiple outer joins syntax

    - by Craig McGuff
    I have the following models user has_many :leave_balances leave_balance belongs_to :user belongs_to :leave_type leave_type has_many :leave_balances I want to output a table format showing user names and their balance by leave type. Not every user can have every balance i.e. outer joins required. I'd like to see something like this: Employee Annual Leave Sick Leave Bob 10 Fred 9 Sara 12 15 I am unsure how to get this out as a single statement? I am thinking something like User.joins(:leave_balances).joins(:leave_type)

  • How do I solve "405 Method Not Allowed" for our subversion setup?

    - by macke
    We're serving our source code using VisualSVN running on Windows Server 2003. Recently, we split a portion of a project into a new project in it's own repository, and then linked it back to the original project using svn:externals. Since then, we've been having issues when we try to commit files with Subclipse. The error we're getting is: svn: Commit failed (details follow): svn: PROPFIND of '/svn': 405 Method Not Allowed (https://svn.ourserver.com) Googling for a while didn't really help, our config seems to be correct. It should also be noted that we've been running this server for a while no without these problems and apart from splitting the project into two repositories, no changes have been made to the server (ie, config files are the same). It should also be noted that these errors only appear when we try to check in multiple files at once. If we check in one file at a time there are no errors. Also, it only appears in Subclipse as far as we know right now, Versions.app (OS X) seems to work fine so that is our current workaround. So, the questions is how do I analyze the error to find the cause and subsequently fix it? I'm by no means a svn guru and right now I'm clueless. EDIT: It seems we can check in multiple files in the same package, but not files from multiple packages. Also, when I "split" the project into two repositories, I imported the original repository with a new name. I did not do a dump and then import that dump. Could that be the source of our issues, and if so, how would I solve that? EDIT: After some jerking around it seems as though it is indeed related to when checking in files in different repositories. If I try to do a single commit in both Repo A and Repo B (referenced by svn:externals) at the same time, I get the error. Versions.app handles this correctly, but I guess it might just be doing two commits, not a single one. Subclipse fails miserably. For now, we simply do multiple commits, one for Repo A and one for Repo B, that works just fine. If anyone smarter than me could fill in the details why this is happening, whether or not this kind of setup is stupid etc, please go right ahead.

  • Filename of script that instantiates an object

    - by Calvin L
    In PHP, is it possible to get the file name of the script that instantiated an object? For example I have a script called file.php that creates a new instance of class Class. The class has an Error object that, when triggered, returns some error information. I would like to show that file.php triggered the error.

  • How to create a windows service from java app

    - by ideasculptor
    I've just inherited a java application that needs to be installed as a service on XP and vista. It's been about 8 years since I've used windows in any form and I've never had to create a service, let alone from something like a java app (I've got a jar for the app and a single dependency jar - log4j). What is the magic necessary to make this run as a service? I've got the source, so code modifications, though preferably avoided, are possible.

  • Alternative for assigns() in Cucumber with Capybara?

    - by thillerson
    I'm trying out capybara with cucumber to get some better javascript test coverage. I have a lot of steps that check or use things from the Rails integration test helpers, for instance: assigns(:current_user).should_not be_nil No matter how I call assigns, even if I say something like p assigns it errors with: undefined method `template' for nil:NilClass (NoMethodError) So, it seems that I can't do that anymore. Is there an alternative to introspecting what's going on in the controller, or maybe some way of at least running those steps in such a way that I have the integration test stuff back?

How can I capture the value "1" from the url, I'm only using standard routes.

  • MySQL - Calculating fields on the fly vs storing calculated data

    - by Christian Varga
    Hi Everyone, I apologise if this has been asked before, but I can't seem to find an answer to a question that I have about calculating on the fly vs storing fields in a database. I read a few articles that suggested it was preferable to calculate when you can, but I would just like to know if that still applies to the following 2 examples. Example 1. Say you are storing data relating to a car. You store the fuel tank size in litres, and how many litres it uses per 100km. You also want to know how many KMs it can travel, which can be calculated from the tank size and economy. I see 2 ways of doing this: When a car is added or updated, calculate the amount of KMs and store this as a static field in the database. Every time a car is accessed, calculate the amount of KMs on the fly. Because the cars economy/tank size doesn't change (although it could be edited), the KMs is a pretty static value. I don't see why we would calculate it every single time the car is accessed. Wouldn't this waste cpu time as opposed to simply storing it in a separate field in the database and calculating only when a car is added or updated? My next example, which is almost an entirely different question (but on the same topic), relates to counting children. Let's say we have a app which has categories and items. We have a view where we display all the categories, and a count of all the items inside each category. Again, I'm wondering what's better. To perform a MySQL query to count all the items in each category every single time the page is accessed? Or store the count in a field in the categories table and update when an item is added / deleted? I know it is redundant to store anything that can be calculated, but I worry that calculating fields or counting records might be slow as opposed to storing the data in a field. If it's not then please let me know, I just want to learn about when to use either method. On a small scale I guess it wouldn't matter either way, but apps like Facebook, would they really count the amount of friends you have every time someone views your profile or would they just store it as a field? I'd appreciate any responses to both of these scenarios, and any resource that might explain the benefits of calculating vs storing. Thanks in advance, Christian

  • How to specify number of headers in section UITableView.

    - by Mr. McPepperNuts
    if ([tempArray containsObject: [sectionInfo indexTitle]]) { return nil; }else { [tempArray addObject: [sectionInfo indexTitle]]; return [sectionInfo indexTitle]; } return [sectionInfo indexTitle]; The code above groups the cells in alphabetical order but displays a blank header instead of the appropriate title. Could this possibly be because I did not specify the number of headers? This would naturally be a single header for every letter in the alphabet.
