Below are shown my classes of sysOperation framework, my problem is when i open the dialog and i press OK , nothing happens, what's wrong with this code?
My service class:
class ProdutionFLowsService extends SysOperationServiceBase
{
ProductionFlowId idOfCopy;
int copyToDo;
ProdTable prodTable;
public void process(ProdutionFLowsContract _contract)
{
this.getPromptParameters(_contract);
select firstonly ProdId
from prodTable
order by ProdId
where prodTable.ProductionFlowId == this.idOfCopy;
this.insertInProdTable();
}
public void insertInProdTable()
{
ProdTable _prodTable;
while(copyToDo > 0)
{
buf2Buf(prodTable,_prodTable);
_prodTable.RecId = 0;
_prodTable.ProdId = _prodTable.Type().initProdId(true);
_prodTable.GAP035ProductionFlowId = _prodTable.ProductionFlowId;
_prodTable.insert();
copyToDo--;
}
}
public void getPromptParameters(ProdutionFLowsContract _contract)
{
copyToDo = _contract.parmCopyToDo();
idOfCopy = _contract.parmidOfCopy();
}
}
My controller class:
class ProdutionFLowsController extends SysOperationServiceController
{
public void new()
{
super();
super(classStr(ProdutionFLowsService), methodStr(ProdutionFLowsService, process), SysOperationExecutionMode::Synchronous);
this.parmDialogCaption("TODO");
}
public static void main(Args _args)
{
ProdutionFLowsController controller = new ProdutionFLowsController();
controller.parmArgs(_args);
controller.startOperation();
}
}
My Contract Class:
[DataContractAttribute]
class ProdutionFLowsContract implements SysOperationInitializable,SysOperationValidatable
{
ProductionFlowId idOfCopy;
int copyToDo;
public void initialize()
{
idOfCopy = "";
copyToDo = 0;
}
[DataMemberAttribute("idOfCopy"),SysOperationLabelAttribute(literalStr("TODO(Id)")),SysOperationDisplayOrderAttribute("1")]
public ProductionFlowId parmidOfCopy(ProductionFlowId _idOfCopy = idOfCopy)
{
idOfCopy = _idOfCopy;
return idOfCopy;
}
[DataMemberAttribute("copyToDo"),SysOperationLabelAttribute(literalStr("copyToDo(Copy)")),SysOperationDisplayOrderAttribute("2")]
public int parmCopyToDo(int _copyToDo = copyToDo)
{
copyToDo = _copyToDo;
return copyToDo;
}
public boolean validate()
{
return false;
}
}
Your contract validation always fails because it always returns false and doesn't show any error in the infolog:
public boolean validate()
{
return false;
}
Try to replace return false with return true or to remove SysOperationValidatable and validate method altogether.

I didn't know about p:collector. I created this custom abstract class:
abstract public class Wrapper<T> {
protected Integer number;
protected List<T> list;
protected Class<T> klass;
public Wrapper() {
this.setList(new ArrayList<T>());
}
public void setListNumber(Integer number) {
Class<T> klass = this.getKlass();
List<T> list = this.getList();
ListUtil.setSize((ArrayList<T>) list, number, klass);
}
public void add() {
List<T> list = this.getList();
Class<T> klass = this.getKlass();
try {
list.add(klass.newInstance());
}
catch (InstantiationException e) {
throw new InstantiationUncheckedException(e);
}
catch (IllegalAccessException e) {
throw new IllegalAccessUncheckedException(e);
}
}
public void remove(int i) {
List<T> list = this.getList();
list.remove(i);
}
public Integer getNumber() {
return number;
}
public void setNumber(Integer number) {
this.number = number;
}
public List<T> getList() {
return list;
}
public void setList(List<T> list) {
this.list = list;
}
public Class<T> getKlass() {
return klass;
}
public void setKlass(Class<T> klass) {
this.klass = klass;
}
}
and I usually use it this way:
public class Things extends Wrapper<Thing> {
public Things() {
super();
this.setKlass(Thing.class);
}
#Override
public String toString() {
return "Things [number=" + number + ", list=" + list + "]";
}
}
and in the view, for example:
<ui:repeat varStatus="status" var="thing" value="#{bean.things.list}">
and
<p:commandButton
value="Add"
action="#{bean.things.add()}"
immediate="true"
/>
<p:commandButton
value="❌"
action="#{bean.licenze.remove(status.index)}"
immediate="true"
/>
p:collector collector could do this better/with less code?
p:collector was removed in PrimeFaces 11 after being deprecated in 10, so better not use it if you ever want to upgrade.
I realized recently that a switch doesn't have a command. And i need to bind the toggling event to my view model. How do i go about it?
I tried to bind the command to Toggled event but the code is running into error
You can use EventToCommandBehavior to convert the event to command
create the EventToCommandBehavior class
using System;
using Xamarin.Forms;
namespace xxx
{
public class BehaviorBase<T> : Behavior<T> where T : BindableObject
{
public T AssociatedObject { get; private set; }
protected override void OnAttachedTo(T bindable)
{
base.OnAttachedTo(bindable);
AssociatedObject = bindable;
if (bindable.BindingContext != null)
{
BindingContext = bindable.BindingContext;
}
bindable.BindingContextChanged += OnBindingContextChanged;
}
protected override void OnDetachingFrom(T bindable)
{
base.OnDetachingFrom(bindable);
bindable.BindingContextChanged -= OnBindingContextChanged;
AssociatedObject = null;
}
void OnBindingContextChanged(object sender, EventArgs e)
{
OnBindingContextChanged();
}
protected override void OnBindingContextChanged()
{
base.OnBindingContextChanged();
BindingContext = AssociatedObject.BindingContext;
}
}
}
using System;
using System.Reflection;
using System.Windows.Input;
using Xamarin.Forms;
namespace xxx
{
public class EventToCommandBehavior : BehaviorBase<View>
{
Delegate eventHandler;
public static readonly BindableProperty EventNameProperty = BindableProperty.Create("EventName", typeof(string), typeof(EventToCommandBehavior), null, propertyChanged: OnEventNameChanged);
public static readonly BindableProperty CommandProperty = BindableProperty.Create("Command", typeof(ICommand), typeof(EventToCommandBehavior), null);
public static readonly BindableProperty CommandParameterProperty = BindableProperty.Create("CommandParameter", typeof(object), typeof(EventToCommandBehavior), null);
public static readonly BindableProperty InputConverterProperty = BindableProperty.Create("Converter", typeof(IValueConverter), typeof(EventToCommandBehavior), null);
public string EventName
{
get { return (string)GetValue(EventNameProperty); }
set { SetValue(EventNameProperty, value); }
}
public ICommand Command
{
get { return (ICommand)GetValue(CommandProperty); }
set { SetValue(CommandProperty, value); }
}
public object CommandParameter
{
get { return GetValue(CommandParameterProperty); }
set { SetValue(CommandParameterProperty, value); }
}
public IValueConverter Converter
{
get { return (IValueConverter)GetValue(InputConverterProperty); }
set { SetValue(InputConverterProperty, value); }
}
protected override void OnAttachedTo(View bindable)
{
base.OnAttachedTo(bindable);
RegisterEvent(EventName);
}
protected override void OnDetachingFrom(View bindable)
{
DeregisterEvent(EventName);
base.OnDetachingFrom(bindable);
}
void RegisterEvent(string name)
{
if (string.IsNullOrWhiteSpace(name))
{
return;
}
EventInfo eventInfo = AssociatedObject.GetType().GetRuntimeEvent(name);
if (eventInfo == null)
{
throw new ArgumentException(string.Format("EventToCommandBehavior: Can't register the '{0}' event.", EventName));
}
MethodInfo methodInfo = typeof(EventToCommandBehavior).GetTypeInfo().GetDeclaredMethod("OnEvent");
eventHandler = methodInfo.CreateDelegate(eventInfo.EventHandlerType, this);
eventInfo.AddEventHandler(AssociatedObject, eventHandler);
}
void DeregisterEvent(string name)
{
if (string.IsNullOrWhiteSpace(name))
{
return;
}
if (eventHandler == null)
{
return;
}
EventInfo eventInfo = AssociatedObject.GetType().GetRuntimeEvent(name);
if (eventInfo == null)
{
throw new ArgumentException(string.Format("EventToCommandBehavior: Can't de-register the '{0}' event.", EventName));
}
eventInfo.RemoveEventHandler(AssociatedObject, eventHandler);
eventHandler = null;
}
void OnEvent(object sender, object eventArgs)
{
if (Command == null)
{
return;
}
object resolvedParameter;
if (CommandParameter != null)
{
resolvedParameter = CommandParameter;
}
else if (Converter != null)
{
resolvedParameter = Converter.Convert(eventArgs, typeof(object), null, null);
}
else
{
resolvedParameter = eventArgs;
}
if (Command.CanExecute(resolvedParameter))
{
Command.Execute(resolvedParameter);
}
}
static void OnEventNameChanged(BindableObject bindable, object oldValue, object newValue)
{
var behavior = (EventToCommandBehavior)bindable;
if (behavior.AssociatedObject == null)
{
return;
}
string oldEventName = (string)oldValue;
string newEventName = (string)newValue;
behavior.DeregisterEvent(oldEventName);
behavior.RegisterEvent(newEventName);
}
}
}
in your xaml
<Switch >
<Switch.Behaviors>
<local:EventToCommandBehavior EventName="Toggled" Command="{Binding ToggledCommand}"/>
</Switch.Behaviors>
</Switch>
And in your ViewModel
public class MyViewModel
{
public ICommand ToggledCommand { get; private set; }
public MyViewModel()
{
ToggledCommand = new Command(() => {
// do some thing you want
});
}
}
I bind a bool property on my viewmodel to the IsToggled property on the switch, then handle when this changes in the viewmodel.
I am using Onion Architecture with Autofac. In my Dependency Injection Code, I am using:
[assembly: WebActivatorEx.PostApplicationStartMethod(typeof(IocConfig), "RegisterDependencies")]

{
var builder = new ContainerBuilder();
builder.RegisterType(typeof(UnitOfWork)).As(typeof(IUnitOfWork)).InstancePerHttpRequest();
builder.Register<IEntitiesContext>(b =>
{
var context = new MyContext("My Connection String");
return context;
}).InstancePerHttpRequest();
}
}
}
Unit Of Work Code:
public class UnitOfWork : IUnitOfWork
{
private readonly IEntitiesContext _context;
private bool _disposed;
private Hashtable _repositories;
public UnitOfWork(IEntitiesContext context)
{
_context = context;
}
public int SaveChanges()
{
return _context.SaveChanges();
}
public IRepository<TEntity> Repository<TEntity>() where TEntity : BaseEntity
{
if (_repositories == null)
{
_repositories = new Hashtable();
}
var type = typeof(TEntity).Name;
if (_repositories.ContainsKey(type))
{
return (IRepository<TEntity>)_repositories[type];
}
var repositoryType = typeof(EntityRepository<>);
_repositories.Add(type, Activator.CreateInstance(repositoryType.MakeGenericType(typeof(TEntity)), _context));
return (IRepository<TEntity>)_repositories[type];
}
public void BeginTransaction()
{
_context.BeginTransaction();
}
public int Commit()
{
return _context.Commit();
}
public void Rollback()
{
_context.Rollback();
}
public void Dispose()
{
Dispose(true);
GC.SuppressFinalize(this);
}
public virtual void Dispose(bool disposing)
{
if (!_disposed && disposing)
{
_context.Dispose();
foreach (IDisposable repository in _repositories.Values)
{
repository.Dispose();// dispose all repositries
}
}
_disposed = true;
}
}
MyContext Code:
public class MyContext : DbContext, IEntitiesContext
{
private ObjectContext _objectContext;
private DbTransaction _transaction;
public MyContext(string nameOrConnectionString)
: base(nameOrConnectionString)
{
}
public void BeginTransaction()
{
_objectContext = ((IObjectContextAdapter)this).ObjectContext;
if (_objectContext.Connection.State == ConnectionState.Open)
{
if (_transaction == null)
{
_transaction = _objectContext.Connection.BeginTransaction();
}
return;
}
_objectContext.Connection.Open(); // At this Line, I am getting Exception
if (_transaction == null)
{
_transaction = _objectContext.Connection.BeginTransaction();
}
}
public int Commit()
{
var saveChanges = SaveChanges();
_transaction.Commit();
return saveChanges;
}
public void Rollback()
{
_transaction.Rollback();
}
}
My problem is, On _objectContext.Connection.Open();, I am getting Connection String missing error.
Below is the screenshot of the Exception:
I Have a Base Interface Like this
public interface IHRMISBaseConnector
{
IHRMISEmployeeConnector EmployeeConnector { get ; set; }
}
And i have one more interface like this
public interface IHRMISEmployeeConnector
{
String Add(EmployeeDetails e);
Boolean Update(EmployeeDetails e);
Boolean Delete(int id);
}
I want implement IHRMISBaseConnector in this class DDWEDocumentOperations
How can i implement ? Please let me know if anybody knows it
Something like this should help you:
class FakeImplementationOfEmployeeConnector : IHRMISEmployeeConnector
{
public string Add(EmployeeDetails e)
{
//...
}
public bool Update(EmployeeDetails e)
{
//...
}
public bool Delete(int id)
{
//...
}
}
class DDWEDocumentOperations : IHRMISBaseConnector
{
IHRMISEmployeeConnector employeeConnector = new FakeImplementationOfEmployeeConnector();
public IHRMISEmployeeConnector EmployeeConnector
{
get
{
return employeeConnector;
}
set
{
employeeConnector = value;
}
}
}
Here is an example:
public class DDWEDocumentOperations : IHRMISBaseConnector
{
private IHRMISEmployeeConnector _employeeConnector;
public IHRMISEmployeeConnector EmployeeConnector
{
get { return _employeeConnector; }
set { _employeeConnector = value; }
}
}
I've wrote some unit-tests for my project who tests my presenters, these presenters queries an EF context with SingleOrDefault, all the unit-tests are successful. But when I run my ASP.NET application I get continuously the error "'Single' not supported by Linq to Entities?" I want to know why this behavior is kicking in? I can't find any documentation about this behavior.

}
public void OnManagedQueryUpdated(ManagedQuery entity)
{

}
public void OnManagedQueryDeleted(ManagedQuery entity)

I believe you can find the answer on this thread Error, method not supported by LINQ to Entities
I was forgotten that unittests are by default in VS2010 written in .NET 4 and my code in .NET3.5 so therefore it isn't working. In EF4 Single(OrDefault) is supported!
