Custom Workflow: Input Properties Empty

Posted on by Community Member

Good day,

I am attempting to start with a very simple custom workflow step. Here's the code:

using System;
using System.Activities;
using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.Workflow;

namespace HTTPRequest
{
    public sealed partial class HTTPRequest : CodeActivity
    {
        protected override void Execute(CodeActivityContext executionContext)
        {
            IWorkflowContext context = executionContext.GetExtension<IWorkflowContext>();
            IOrganizationServiceFactory serviceFactory = executionContext.GetExtension<IOrganizationServiceFactory>();
            IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId);

            this.response.Set(executionContext, this.url.Get(executionContext));
        }

        [RequiredArgument]
        [Input("InputURL")]
        [ReferenceTarget("")]
        public InArgument<String> url { get; set; }

        [Output("Response")]
        public OutArgument<String> response {get; set;}
    }
}

But when I build and register the plugin I get an empty "Set Properties" window:

Any ideas about why this is happening?

Thanks,

BGS

Hey Ivan,

Creating a new standard C# DDL project did the trick!

Thanks for all the help.

Never tried that way, I'm always creating standard C# DLL project and adding a simple C# class when I'm starting new CRM workflows project.

I just noticed that you created your class as "public sealed partial class" and I create my classes as public class, you can try to remove that sealed partial part.

Hmmmm, neither of those suggestinos seem to be helping.

I wonder if this could be a problem with how I setup the project?

I started by making a Dynamics 365 Workflow Activity Project:

Then I added a new Dynamics 365 Workflow Activity class:

Is this the correct process I should be following?

Everything else looks good. You can try to switch lines

[RequiredArgument] [Input("InputURL")]

Like

[Input("InputURL")] [RequiredArgument]

And final suggestion if the upper one does not help is to try creating a class with the same code and different name than this one and try to deploy it like that. It will not be the first time that thing like that will fix the issue, I experienced it few times and I still don't know what is causing that issue.

Removing the reference target line didn't seem to change anything.

Sounds good, thanks for the tip.

Try to remove line

[ReferenceTarget("")]

from your input parameter declaration.

And just a friendly suggestion is that you define input and output parameters above Execute function just to make it more readable for other developers that will collaborate on this project.
