Dynamics CRM 2011的自动命名生成器插件在进入执行之前崩溃

Question

I have a custom entity acm_lidmaatschapbedrijf which I have to automatically generate a name for when it's created, so the user doesn't need to do this himself.

I got the following class for this, which :

protected class LocalPluginContext
    {
        internal IOrganizationService OrganizationService
        {
            get;
            private set;
        }

        internal IPluginExecutionContext PluginExecutionContext
        {
            get;

            private set;
        }

        internal ITracingService TracingService
        {
            get;

            private set;
        }

        internal LocalPluginContext(IServiceProvider serviceProvider)
        {
            if (serviceProvider == null)
            {
                throw new ArgumentNullException("serviceProvider");
            }

            // Obtain the execution context service from the service provider.
            PluginExecutionContext = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));

            // Obtain the tracing service from the service provider.
            TracingService = (ITracingService)serviceProvider.GetService(typeof(ITracingService));
            Trace("Tracingservice aangemaakt.");
            // Obtain the Organization Service factory service from the service provider
            IOrganizationServiceFactory factory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
            Trace("Factory aangemaakt");
            // Use the factory to generate the Organization Service.
            OrganizationService = factory.CreateOrganizationService(PluginExecutionContext.UserId);
            Trace("Service aangemaakt");
        }

        internal void Trace(string message)
        {
            if (string.IsNullOrWhiteSpace(message) || TracingService == null)
            {
                return;
            }
            if (PluginExecutionContext == null)
            {
                TracingService.Trace(message);
            }
            else
            {
                TracingService.Trace(
                    "{0}, Correlation Id: {1}, Initiating User: {2}",
                    message,
                    PluginExecutionContext.CorrelationId,
                    PluginExecutionContext.InitiatingUserId);
            }
        }
    }


    public void Execute(IServiceProvider serviceProvider)
    {
        if (serviceProvider == null)
        {
            throw new ArgumentNullException("serviceProvider");
        }

        // Construct the Local plug-in context.
        LocalPluginContext localcontext = new LocalPluginContext(serviceProvider);
        //Get the entity;
        localcontext.Trace("Localcontext aangemaakt");
        acm_lidmaatschapbedrijf lidmaatschapbedrijf = ((Entity)localcontext.PluginExecutionContext.InputParameters["Target"]).ToEntity<acm_lidmaatschapbedrijf>();
        //Check whether the linked lidmaatschap is the right one;
        localcontext.Trace("lidmaatschapbedrijf opghaald");
        acm_lidmaatschap lidmaatschapcategorie = localcontext.OrganizationService.Retrieve(acm_lidmaatschap.EntityLogicalName, lidmaatschapbedrijf.acm_typelidmaatschap.Id, new ColumnSet(new[] { "acm_typelidmaatschap" })).ToEntity<acm_lidmaatschap>();
        localcontext.Trace("Categorie opgehaald");
        localcontext.Trace(string.Format("Categorie = {0}", lidmaatschapcategorie.acm_typelidmaatschap.Value));
        if (lidmaatschapcategorie.acm_typelidmaatschap.Value != 805210000)
        {
            throw new InvalidPluginExecutionException("Het type lidmaatschap is niet bedrijf.");
        }
        //assign name
        lidmaatschapbedrijf["acm_name"] = string.Format("{0} {1}", "Bedrijfslidmaatschap", lidmaatschapbedrijf.acm_account.Name);
        localcontext.Trace(string.Format("Nieuwe naam = {0}", lidmaatschapbedrijf.acm_name));
        localcontext.PluginExecutionContext.InputParameters["Target"] = lidmaatschapbedrijf;
        localcontext.Trace("Target opnieuw toegekend");


    }
}

This is how the plugin is registered

It appears like the plugin is launched, but it crashes with the following error dump:

As you can see, it doesn't show any traces. it just crashes and I don't know why. Do you need to do any special settings to use InputParameters["Target"]?

Answer 1

The serialization error comes from the following line :

localcontext.PluginExecutionContext.InputParameters["Target"] = lidmaatschapbedrijf;

You can't assign an early bound entity to InputParameter["Target"] . The assignment must be a late-bound Entity ie Entity()

This is Ok

Entity lidmaatschapbedrijf = new Entity("new_ lidmaatschapbedrijf")
lidmaatschapbedrijf.acm_name = "constructed name";
localcontext.PluginExecutionContext.InputParameters["Target"] = lidmaatschapbedrijf;

You can also do this...

localcontext.PluginExecutionContext.InputParameters["Target"] = lidmaatschapbedrijf.ToEntity<Entity>();
