Hi,

I have some warning/error message in the Logs and I would like to know if they are "normal" or should be treated (how ?).

The application doesn't know the model, after the login we download a XAP file which have 3 assemblies. One for the model, one named services where the UOF, connectionsoptions, etc are located and the last one having the view/viewmodels and providing few other services
In this last one, one service (named CompanyRequirementVerificator, see below) need to import a UOW. 

The Log below are shown just before the call of UpdateAssemblySourceFromCatalog
 in the FrameworkBootstrapper.OnCatalogRecomposed methode.


'iexplore.exe' (Silverlight) : 'MyApp.Commun.Services' chargé, symboles chargés.
'iexplore.exe' (Silverlight) : 'c:\Program Files (x86)\Microsoft Silverlight\5.0.61118.0\fr\mscorlib.debug.resources.dll' chargé
'iexplore.exe' (Silverlight) : 'MyApp.Commun.Domain.SL' chargé, symboles chargés.
'iexplore.exe' (Silverlight) : 'MyApp.Context.AutoLoad' chargé, symboles chargés.
System.ComponentModel.Composition Warning: 1 : The ComposablePartDefinition 'MyApp.Context.AutoLoad.Verificators.EtablissementRequirementVerificator' has been rejected. The composition remains unchanged. The changes were rejected because of the following error(s): The composition produced a single composition error. The root cause is provided below. Review the CompositionException.Errors property for more detailed information.

1) No valid exports were found that match the constraint '((exportDefinition.ContractName == "MyApp.Interfaces.Repositories.IUnitOfWorkManager(MyApp.Commun.Services.UnitsOfWork.ISelectionEtbUnitOfWork)") AndAlso (exportDefinition.Metadata.ContainsKey("ExportTypeIdentity") AndAlso "MyApp.Interfaces.Repositories.IUnitOfWorkManager(MyApp.Commun.Services.UnitsOfWork.ISelectionEtbUnitOfWork)".Equals(exportDefinition.Metadata.get_Item("ExportTypeIdentity"))))', invalid exports may have been rejected.

Resulting in: Cannot set import 'MyApp.Context.AutoLoad.Verificators.EtablissementRequirementVerificator..ctor (Parameter="unitOfWorkManager", ContractName="MyApp.Interfaces.Repositories.IUnitOfWorkManager(MyApp.Commun.Services.UnitsOfWork.ISelectionEtbUnitOfWork)")' on part 'MyApp.Context.AutoLoad.Verificators.EtablissementRequirementVerificator'.
Element: MyApp.Context.AutoLoad.Verificators.EtablissementRequirementVerificator..ctor (Parameter="unitOfWorkManager", ContractName="MyApp.Interfaces.Repositories.IUnitOfWorkManager(MyApp.Commun.Services.UnitsOfWork.ISelectionEtbUnitOfWork)") -->  MyApp.Context.AutoLoad.Verificators.EtablissementRequirementVerificator -->  AssemblyCatalog (Assembly="MyApp.Context.AutoLoad, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null")



later, after the call to UpdateAssemblySourceFromCatalog, have those Logs :

181 : 25/04/2012 20:08:42 :  : IdeaBlade.Core.Composition.PartsCatalog:OnRecomposed : Dynamic content added: MyApp.Context.AutoLoad.xap, loaded without error

As you can see, it say on the line 181 all is done without error. And it's true as I can use the module CompanyRequirementVerificator which generated the first warning.

I did another test. I removed the Model from the XAP and added a reference to it in the main application. In this case I have no error in the logs.

Walid,
There's an issue in the underlying DevForce XAP functionality that Cocktail relies on. It will be fixed in the next version of DevForce scheduled to ship on May 2. In the meantime you can work around the issue by adding the following to your bootstrapper.
 
        protected override ComposablePartCatalog PrepareCompositionCatalog()
        {
            // Create alternative AggregateCatalog to group recomposition events.
            var currentCatalogs = Composition.AggregateCatalog.Catalogs.ToList();
            var catalog = new AggregateCatalog();
 
            // Add current catalogs as a single group
            catalog.Catalogs.Add(new AggregateCatalog(currentCatalogs));
            Composition.Recomposed +=
                (sender, args) =>
                {
                    // Find new catalogs.
                    var newCats =
                        Composition.AggregateCatalog.Catalogs.Where(c => !currentCatalogs.Contains(c)).ToList();
                    currentCatalogs.AddRange(newCats);
 
                    // Add new catalogs as a single group
                    catalog.Catalogs.Add(new AggregateCatalog(newCats));
                };
 
            return catalog;
        }

to have the interception I changed

        return catalog;

by
            InterceptionConfiguration cfg = new InterceptionConfiguration().AddInterceptor(this);
            return new InterceptingCatalog(catalog, cfg);


It did correct the first error but not the second one
176 : 25/04/2012 20:08:42 :  : IdeaBlade.Core.Composition.PartsCatalog:LoadCatalogCore : Error loading assembly 'MyApp.Commun.Services.dll' for PartsCatalog, but will retry.  Initial error: Impossible de charger un ou plusieurs des types requis.

I have the error in every xxx.Services assemblies (in others XAP).

You can ignore this one. Depending on your reference dependencies between the assemblies in the XAP it's not always possible to load them all in the first pass. As the message states, it will retry. Given that you no longer have composition errors, it succeded the second time. You can try cleaning up unused references, which may make the error go away.

Looks like the permissions are set wrong for the Cocktail forum. We are fixing it.

Two permissions - Edit and Delete - did not propagate to this new forum. That has been corrected and all registered users now have those rights. My appologies for the error!
