Symfony2 - Compiler Passes - symfony

I want to change the value of a parameter located in parameters.yml from my controller
with
$this->container->setParameter('myParam','newValue');
I get an error : Impossible to call set() on a frozen ParameterBag
I really looked for a solution but I have not understood how compile passes work
does someone can give me a simple example
UPDATE:
I have some parameters stored there (my mailbox, the LAPD parameters, etc ..) I would like to give control to the admin to configure it from the dashboard

Expression variables have been defined for constraint interface ... while Expression Language is not enabled

I have project, with some custom ConstraintValidator. I wanted to build custom message. I did so and everyting works just fine. Then we met need to have 'api' module, which means, that you have to split bean validation annotation and ConstraintValidator, have to use #Constraint(validatedBy = {}) and setup pairing manually using ConstraintMapping. Everyting stil works, except for message interpolation.
Log now contains kinda cryptic message:
Expression variables have been defined for constraint interface whatever.SomeValidation while Expression Language is not enabled.
All of that while I'm literary using the same code as one mentioned here:
https://docs.jboss.org/hibernate/stable/validator/reference/en-US/html_single/#_custom_contexts
to disableDefaultConstraintViolation and register custom one.
Any ideas what can cause that?

How to Generate Controller in Symfony 3.0?

Hope you are all fine, I am a beginner trying to learn Symfony 3.0, so I want to generate my controller in a folder called Bundles, but it is not created, here is the command I taped :
php bin/console generate:controller
And this is fine, when I tape the controller name, that was what I wrote :
?[32mController name?[39m: Bundles/FrontBundle
But their answer is :
?[37;41m The controller name must contain a : ("Bundles/FrontBundle"
given, expecting something like AcmeBlogBundle:Post) ?[39;49m
I don't know if I have to do something before this to noy have such error.
Any Help would be much appreciated.
This is because controller name should be a combination of BundleName:ControllerName and you have provided a relative path to your bundle. If that doesn't work make sure you have your autloading properly setup and Symfony knows about your bundle
According to his doc you should use the shortcut notation when you are declaring a controller, entity, etc.
also you need to read the output of the command.
Welcome to the Symfony controller generator
Every page, and even sections of a page, are rendered by a controller.
This command helps you generate them easily.
First, you need to give the controller name you want to generate. You
must use the shortcut notation like AcmeBlogBundle:Post
Controller name: BundleNameEndingBundle:ControllerName

Functionality change while upgrading to Castle Windsor 3.3.0 from 3.2.0

I am attempting to migrate from version 3.2.0 to 3.3.0. I am getting a compile error. I could not find an entry in the "Breaking Changes" section but here are my two errors in hope someone can guide me to a workable alternative.
public void RegisterTypeSingleton<T>(Type component, string name)
{
if (_container.Kernel.HasComponent(name))
_container.Kernel.RemoveComponent(name);
_container.Register(Component.For<T>().ImplementedBy(component).Named(name).LifeStyle.Singleton);
}
It seems Kernel.RemoveComponent() function has been depreciated. What has replaced this?
The second compiler error is at _container.Register(Component.For<T>().ImplementedBy(component).Named(name).LifeStyle.Singleton);
I am getting "The Type 'TService' must be a reference type in order to use it as a parameter.
I think you might be upgrading from an older version than 3.2.0. See below.
The removal of IKernel.RemoveComponent() is documented in the Breaking Changes document with v3.0.0. Here is the extract where Krzysztof explains why it was removed:
change - Removed the following methods:
GraphNode.RemoveDepender,
GraphNode.RemoveDependent,
IKernel.RemoveComponent,
IKernelEvents.ComponentUnregistered,
INamingSubSystem.this[Type service],
INamingSubSystem.GetHandler,
INamingSubSystem.GetService2Handler,
INamingSubSystem.GetKey2Handler,
INamingSubSystem.UnRegister(String key),
INamingSubSystem.UnRegister(Type service)
Also INamingSubSystem.Register now takes only IHandler as its argument
impact - low
fixability - none
description - The methods were implementation of "remove component from the container" feature
which was flawed and problematic, hecen was scraped.
fix - Working around is quite dependant on your specific usage. Try utilizing IHandlerSelectors.
For changed Register method, just update your calling code not to pass the name.
handler.ComponentModel.Name is now used as the key, as it was happening in all places so far
anyway, so this change should have no real impact.
RegisterComponent() won't overwrite an existing service registration, it'll just register another component for the same service, unless you specify the same name where it'll throw an exception informing you there is another component registered with that name. If your application doesn't replace components very often you could use the IsDefault() method on the registration to get Windsor to resolve the new component by default, just note the other component is still registered.
If your application replaces components often and you don't want the other registrations left there, you'd be best using a custom IHandlerSelector or ISubDependencyResolver so Windsor will ask you each time what component you want used for a specific service.
Also in v3.0.0 a change was made to ensure that value types cannot be passed to the registration methods. You'll need to add a generic constraint to your method that accepts a generic parameter so that it also only accepts reference types:
public void RegisterTypeSingleton<T>(Type component, string name)
where T : class
{
...
}

How can a Tridion command extension find out the command it extends?

Tridion's user interface allows you to extend specific commands, which is a great way to modify the behavior of certain existing commands. In the configuration file of the editor this is done with a section like this:
<ext:commands>
<ext:command name="TextUnderline" extendingcommand="MyTextUnderline"/>
<ext:command name="TextStrikethrough" extendingcommand="MyTextStrikethrough"/>
I am working on a generic command extension class that can be used to modify the behavior of a number of commands:
<ext:commands>
<ext:command name="TextUnderline" extendingcommand="MyCommandExtension"/>
<ext:command name="TextStrikethrough" extendingcommand="MyCommandExtension"/>
So in this second configuration fragment, we have the same MyCommandExtension extending both TextUnderline and TextStrikethrough.
But now in the JavaScript for my MyCommandExtension, how can I determine which command was originally fired?
MyCommandExtension.prototype.isAvailable = function (selection, pipeline) {
...
console.log(this.properties.name);
...
};
In this scenario the this.properties.name will be logged as a less-than-useful-but-completely-correct:
"DisabledCommand"
I suspect that the information is available somewhere in the pipeline parameter, but haven't found it yet.
How can I find out the original command from MyCommandExtension?
Short answer: I couldn't.
I had to do something similar, and ended up having to extend various commands and set the "current" command as part of my "_execute" call (so I would now call _execute(selection, pipeline, originalCommand) for my command.
N
You cannot find out what the original command is. The assumption is that an extending command is specific to the command it extends and so would know which one it is extending. When creating generic extensions that work on different commands, I can see how it might be useful to know what the configuration would be.
Maybe you could add this as an Enhancement Request?
To work around it for now, you could create a base command with your logic - which takes the name of the command that it extends as a parameter. And then create specific classes for each command you which to extend, which just call the base command and pass in the name.
To put it differently, create a BaseExtendingCommand with all of the required methods - and then both a TextUnderlineExtendingCommand and TextStrikethroughExtendingCommand which call the methods on BaseExtendingCommand (and pass in "TextUnderline" and "TextStrikethrough", respectively, as arguments)

How do I get an ID after saving an ExtBase Model?

After creating a model and adding it to a repository I want to have the new ID for different purposes (creating a mail, updating other fields outside the Extbase world)
$page = t3lib_div::makeInstance('Tx_MyExt_Domain_Model_Page');
$page->setTitle('Hello World');
$this->pageRepository->add($page);
At this point $page hasn't got an ID yet, uid is null.
$page->getUid(); // returns null
When does it get it? And how can I retrieve in on runtime?
In ExtBase, objects are "managed". This means every persistence transaction (add/remove/update) is simply noted in the underlying logic, but not yet executed until the appropriate time (like the end of processing a request). So, just because you add an object to a repository doesn't mean that it's actually added yet. That actually happens once $persistenceManager->persistAll() is called, which isn't something you need to do manually, ever. The point is, your $page object won't have a UID until it's saved and that's why $page->getUid() returns null. Look here for a great explanation.
I suspect that you are trying to do something outside of the ExtBase object/MVC lifecycle. At least, last time I got null when I tried to get the UID of an object, it was because I wasn't operating within the framework appropriately.
However, if you post some more code and give us a bigger picture of what you're trying to achieve, maybe we can help you get to a point where that object actually has a UID. For instance, if you're in a Controller object, tell us which Action method you're in, or if you're in a Repository object, tell us what you're trying to get from the repository and where/how you plan on using the query results.
EDIT
Just guessing here, but I'm assuming you're executing this code in some action of a controller. Since after the controller is executed a view is rendered, you can just pass the page object to the view:
$this->view->assign('page', $page);
And then in your view you can use the page object in a link:
<f:link.action action="show" arguments="{page:page}">
See this page object
</f:link.action>
And then in the show action of your controller you can show the page:
public function showAction(Tx_MyExt_Domain_Model_Page $page) {
// Do whatever you need to show the page in the `Show.html` template
}
I really am just guessing here. If you can give us a larger picture of what you're trying to do, what your action methods are supposed to do and things like that, we can answer your question a little more confidently.
(I'm also assuming that your page object isn't a replacement for the regular TYPO3 pages and that they are something totally different. It's much easier to deal with those TYPO3 pages through the backend interface than at the php level.)
You can call persistence manager explicitly in Your controller like this
#TYPO3 4.x
$persistenceManager = $this->objectManager->create('Tx_Extbase_Persistence_Manager');
$persistenceManager->persistAll();
#TYPO3 6.x
$persistenceManager = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\CMS\Extbase\Persistence\Generic\PersistenceManager');
$persistenceManager->persistAll();
