I know we can use components with the admin generator (thanks to ~ symbol).
However, in the components.class.php, how to call the auto-generated class ?
At this moment, I'm using this :
require_once dirname(__FILE__).'/../lib/commissionGeneratorConfiguration.class.php';
require_once dirname(__FILE__).'/../lib/commissionGeneratorHelper.class.php';
class commissionComponents extends autoCommissionComponents
{
}
But I obtain this error :
Fatal error: Class 'autoCommissionComponents' not found in /home/site/liguelorraine/apps/saSecureLigueLorraine/modules/commission/actions/components.class.php on line 7
There are no automatically generated component classes. Just extends sfComponents as usual.

PHP Error : Fatal error: Constant expression contains invalid operations
(5 answers)
Closed 4 years ago.
I have the following code, where I get the error "PHP Fatal Error: Constant expression contains invalid operations". It works fine when I define the variable in the constructor. I am using Laravel framework.
<?php
namespace App;
class Amazon
{
protected $serviceURL = config('api.amazon.service_url');
public function __construct()
{
}
}
I have seen this question: PHP Error : Fatal error: Constant expression contains invalid operations
But my code does not declare anything as static, so that did not answer my question.
As described here
Class member variables are called "properties". You may also see them referred to using other terms such as "attributes" or "fields", but for the purposes of this reference we will use "properties". They are defined by using one of the keywords public, protected, or private, followed by a normal variable declaration. This declaration may include an initialization, but this initialization must be a constant value--that is, it must be able to be evaluated at compile time and must not depend on run-time information in order to be evaluated.
The only way you can make this work is :-
<?php
namespace App;
class Amazon
{
protected $serviceURL;
public function __construct()
{
$this->serviceURL = config('api.amazon.service_url');
}
}
Initializing class properties is not allowed this way. You must move the initialization into the constructor.
Another working alternative I used is with boot( ) with Laravel Eloquent:
<?php
namespace App;
class Amazon {
protected $serviceURL;
protected static function boot()
{
parent::boot();
static::creating(function ($model){
$model->serviceURL = config('api.amazon.service_url');
});
} }
I have implemented my version of ICultureSelector, in a custom module.
Here it is a part of its definition (my question is not about the logic to select the culture; I tried with my own namespace and also with a namespace same as the namespace used in the module Orchard.Localization):
namespace Orchard.Localization.Selectors
{
[OrchardFeature("Orchard.Localization.CultureSelector")]
public class ShortRouteCultureSelector : ICultureSelector
{
public CultureSelectorResult GetCulture(HttpContextBase context)
{
...
I put a breakpoint in the method GetCurrentCulture of the class CurrentCultureWorkContext in the Orchard.Framework project, and I see that the variable IEnumerable _cultureSelectors contains all the implementation of ICultureSelector of the module Orchard.Localization but not my implementation, that is never used.
What am I missing?
Remove the OrchardFeature attribute or define your own feature name as Orchard.Localization.CultureSelector is defined in Orchard.Localization module already.
I created a new project with Lumen 5.4.7 and I added the TCPDF library from elibyy/tcpdf-laravel version 5.4.2 (with Lumen support):
composer require elibyy/tcpdf-laravel "5.4.2"
I enabled the Facades and Service Provider in bootstrap/app.php with
$app->withFacades();
$app->register(Elibyy\TCPDF\ServiceProvider::class);
And I created a basic Controller:
<?php
namespace App\Http\Controllers;
use \PDF;
class PdfController extends Controller
{
/**
* Create a test PDF file.
*
* #return void
*/
public function createTestPdf()
{
PDF::SetTitle('Hello World');
PDF::AddPage();
PDF::Write(0, 'Hello World');
PDF::Output('hello_world.pdf');
echo "Fatto!";
}
}
with a basic route:
$app->get('pdf', 'PdfController#createTestPdf');
But when I try to access to /pdf I get the following error:
Fatal error: Class 'PDF' not found in /Users/m/Documents/Projects/lumen-pdf/app/Http/Controllers/PdfController.php on line 15
(1/1) FatalErrorException
Class 'PDF' not found
in PdfController.php (line 15)
at Application->handleShutdown()
in RegistersExceptionHandlers.php (line 54)
at Application->Laravel\Lumen\Concerns\{closure}()
Could you help me please?
I solved my problem.
One line was missing into bootstrap/app.php to add a new class_alias for Elibyy\TCPDF\Facades\TCPDF to PDF:
class_alias('Elibyy\TCPDF\Facades\TCPDF', 'PDF');
Thanks!
I am using Vaadin-7 and this answer was not fix for me .
I am trying to import my js file under myproject/WebContent/js/test.js . I used #JavaScript in my UI class as below..
#Theme("myTheme")
#SuppressWarnings("serial")
#Title("VaadinTest")
#JavaScript("js/test.js")
public class VaadinTest extends UI {
#Override
protected void init(VaadinRequest request) {
final VerticalLayout layout = new VerticalLayout();
layout.setMargin(true);
setContent(layout);
}
}
But I got "NetworkError: 404 Not Found - http://localhost:8080/myproject/APP/PUBLISHED/js/test.js" error log in my firebug console.
So , how can I import js files from my custom directories ?
PS: Please don't be force me to create APP/PUBLISHED/ directory manually ! Thanks.
You can use app://:
#JavaScript({ "app://js/test.js" })
or use:
#JavaScript({ "vaadin://js/test.js" })
Generated url inside VAADIN folder:
http://localhost:8080/myproject/VAADIN/js/test.js
the file you refer to must be reachable by the classloader relative to the package you are using it in. according to your example, lets say your package of VaadinTest is com.example.app and you want to access it as js/test.js you have to put it in the directory com/example/app/js/test.js in a "root" for the classloader to find it (e.g. src/main/java,groovy or where resources are loaded from in your config).
I created a bare-bones datagrid using web-ui for testing and had it working just fine. Then I decided to try to declare it as a component. I changed around the library references and now it is giving me the above error when I try to run the application. You can see my file structure below. The reason I am getting the "ambiguous reference" message when I try to run it is that when I went into the auto-generated DataGrid.dart file in the out directory, it had the following declaration
import 'DataGrid.dart';
...
import '../DataGrid.dart';
I am confused as to why the generated code imports them both. One thing that I considered is that it could be because the DataGridPage.html file instantiates my DataGrid component and my DataGridPage.dart file imports DataGrid.dart so that it can have references to DataGridColumn (it needs to set the columns for the DataGrid). In DataGridPage.dart, I also attach to certain DataGrid events such as SortColumnChanged and SelectionChanged so I need to request a copy of my DataGrid instance in DataGridPage.dart (I don't think there is a way to attach to events from the web component instantiation in DataGridPage.html).
Any ideas about what I am doing wrong?
Here is my file structure:
DataGrid.dart
--------------------------------------------
library datagrid;
...
part 'DataGridColumn.dart';
part 'DataGridRow.dart';
class DataGrid extends WebComponent{...}
DataGridRow.dart
--------------------------------------------
part of datagrid;
class DataGridRow {...}
DataGridColumn.dart
--------------------------------------------
part of datagrid;
class DataGridColumn {...}
DataGrid.html
--------------------------------------------
[contains the component declaration UI]
DataGridPage.html
-----------------------------------------
...
<div is="s-datagrid" id="myDataGrid" ItemsSource="{{app.Assets}}" Columns="{{app.Columns}}"></div>
...
DataGridPage.dart
--------------------------------------------
import 'DataGrid.dart';
import 'Asset.dart';
void main() {
}
DataGridApp _app;
DataGridApp get app {
if (_app == null) {
_app = new DataGridApp();
}
return _app;
}
class DataGridApp{
//provides ItemsSource and DataGridColumn data
}
jmesserly has answered this on the github site. He said that you need to remove the component import in your main dart file. So in my example I would remove the import 'DataGrid.dart' statement from the DataGridPage.dart. The IDE will give you a warning but you can ignore it because it will actually be run from the out folder.
