Hi,
I am trying to invoke a pipeline using the OrderPipeline.Execute() method. I
am getting the following exception:

InvalidCastException: Specified cast is not valid.]
Microsoft.CommerceServer.Runtime.Pipelines.OrderPipeline.Execute(Object
order, Object context) +108

Is this a proper approach for invoking a pipeline? If so, can someone
provide me details about the arguments passed to this method, especially the
'context' argument?

Thanks

Hi,

What sort of pipeline are you trying to execute? Are you executing inside
an ASP.NET application context? I use the following helper function to
execute pipelines against baskets as an example:

private void RunPipeline(string pipelineName)
{
PipelineInfo pipeInfo;
CommerceContext commerceContext = CommerceContext.Current;

pipeInfo = new PipelineInfo(pipelineName);

// Set pipeline object references
pipeInfo[PipelineFields.CatalogLanguage] =
Thread.CurrentThread.CurrentUICulture.Name;
pipeInfo.CatalogContext = commerceContext.CatalogSystem;
pipeInfo.ProfileContext = commerceContext.ProfileSystem;
pipeInfo.Language = Thread.CurrentThread.CurrentUICulture.Name;

// Attach the user profile to the pipeline.
pipeInfo.Profiles.Add("User", commerceContext.UserProfile);

// If it exists attach the targeting context profile.
if (commerceContext.TargetingSystem.TargetingContextProfile != null)
pipeInfo.Profiles.Add("TargetingContext",
commerceContext.TargetingSystem.TargetingContextProfile);

// Run pipeline
try
{
this.currentBasket.RunPipeline(pipeInfo);
}
catch (CommerceOrderSystemException ex)
{
ExceptionManager.Publish(ex);

if( (((SimpleList)this.orderForm[OrderFormFields.BasketErrors]).Count ==
0) &&
(((SimpleList)this.orderForm[OrderFormFields.PurchaseErrors]).Count ==
0) )
this.AddPurchaseError(StringResources.GetString(StringResourceKeys.Checkout_SystemError));
}

// Populate basket error collection
this.basketErrors.Clear();
foreach (object item in
(SimpleList)this.orderForm[OrderFormFields.BasketErrors])
this.AddBasketError((string)item);

// Populate purchase error collection
this.purchaseErrors.Clear();
foreach (object item in
(SimpleList)this.orderForm[OrderFormFields.PurchaseErrors])
this.AddPurchaseError((string)item);
}
