Custom workflow activity - Output argument problem

Posted on by Community Member

Hello,

I'm trying to create a custom workflow activity to get the contact entity reference from the email.

The goal is to use this functionnality when I create a email in order to get the link on the contact from the email address.

And I have a problem : I can't select my output argument in the update form of the workflow :

Here is my code :

using System.Activities;

using Microsoft.Crm.Sdk.Messages;

using Microsoft.Xrm.Sdk;

using Microsoft.Xrm.Sdk.Workflow;

using Microsoft.Xrm.Sdk.Query;

using Microsoft.Xrm.Sdk.Messages;

using System;

using Microsoft.Xrm.Sdk.Client;

namespace ActivityLibrary3

{

public class CodeActivity1 : CodeActivity

{

[Input("To")]

public InArgument<string> to { get; set; }

[ReferenceTarget("contact")]

[Output("ContactId")]

public OutArgument<EntityReference> ContactId { get; set; }

// If your activity returns a value, derive from CodeActivity<TResult>

// and return the value from the Execute method.

protected override void Execute(CodeActivityContext executionContext)

{

// Obtain the runtime value of the Text input argument

IWorkflowContext context = executionContext.GetExtension<IWorkflowContext>();

//Create an Organization Service

IOrganizationServiceFactory serviceFactory = executionContext.GetExtension<IOrganizationServiceFactory>();

IOrganizationService service = serviceFactory.CreateOrganizationService(context.InitiatingUserId);

// Create query using querybyattribute

QueryByAttribute querybyexpression = new QueryByAttribute("contact");

querybyexpression.ColumnSet = new ColumnSet("contactid", "emailaddress1");

// Attribute to query

querybyexpression.Attributes.AddRange("emailaddress1");

string email = this.to.Get(executionContext);

// Value of queried attribute to return

querybyexpression.Values.AddRange(email);

// Query passed to the service proxy

EntityCollection retrieved = service.RetrieveMultiple(querybyexpression);

// Returned value

foreach (var c in retrieved.Entities)

{

this.ContactId.Set(executionContext, c.Attributes["contactid"]);

break;

}

//Guid contact_id = new Guid();

//foreach (Entity entity in retrieved.Entities)

//{

// contact_id = ((EntityReference)entity.Attributes["contactid"]).Id;

// break;

//}

//this.ContactId.Set(executionContext, contact_id);

}

I've tried different ways (one is in green at the end of the code) but now, I don't know why I can't select my output parameter.

Thank you for your help !!

RE: Custom workflow activity - Output argument problem

In fact, the problem of the output argument unavailable in the workflow form seems to be a Firefox problem.

With IE, I have no issue.

I've tried several codes and this one doesn't generate any issue during the execution, but my target field is empty as a result :

using System.Activities;

using Microsoft.Crm.Sdk.Messages;

using Microsoft.Xrm.Sdk;

using Microsoft.Xrm.Sdk.Workflow;

using Microsoft.Xrm.Sdk.Query;

using Microsoft.Xrm.Sdk.Messages;

using System;

using Microsoft.Xrm.Sdk.Client;

namespace ActivityLibrary6

{

public class CodeActivity1 : CodeActivity

{

[Input("To")]

public InArgument<string> to { get; set; }

　

[ReferenceTarget("contact")]

[Output("ContactId")]

public OutArgument<EntityReference> ContactId { get; set; }

　

　

// If your activity returns a value, derive from CodeActivity<TResult>

// and return the value from the Execute method.

protected override void Execute(CodeActivityContext executionContext)

{

// Obtain the runtime value of the Text input argument

IWorkflowContext context = executionContext.GetExtension<IWorkflowContext>();

//Create an Organization Service

IOrganizationServiceFactory serviceFactory = executionContext.GetExtension<IOrganizationServiceFactory>();

IOrganizationService service = serviceFactory.CreateOrganizationService(context.InitiatingUserId);

// Create query using querybyattribute

QueryByAttribute querybyexpression = new QueryByAttribute("contact");

querybyexpression.ColumnSet = new ColumnSet("contactid", "emailaddress1");

// Attribute to query

querybyexpression.Attributes.AddRange("emailaddress1");

string email = this.to.Get(executionContext);

// Value of queried attribute to return

querybyexpression.Values.AddRange(email);

// Query passed to the service proxy

EntityCollection retrieved = service.RetrieveMultiple(querybyexpression);

// Returned value

// ************ Solution 1

foreach (Entity Entity in retrieved.Entities)

{

this.ContactId.Set(executionContext, Entity.Attributes["contactid"]);

break;

}

}

}

}

Do you have any idea why result is empty ?

RE: Custom workflow activity - Output argument problem

I gives me the following error with your code :

System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.

Parameter name: index

at Microsoft.Crm.Sandbox.SandboxCodeUnit.Execute(IExecutionContext context)

at Microsoft.Crm.Workflow.Services.ProxyCustomActivity.Execute(CodeActivityContext executionContext)

Same error with index[1]

RE: Custom workflow activity - Output argument problem

Try Using

executionContext.SetValue(ContactId, retrieved.Entities[0].GetAttributeValue<EntityReference>("contactid"));

Instead of

foreach (var c in retrieved.Entities)

{

this.ContactId.Set(executionContext, c.Attributes["contactid"]);

break;

}
