Dialog Process throws error

Posted on by Community Member

I am executing a Dialog which uses a custom workflow assembly to generate SSRS report and attach the report PDF to Email. The email activity is passed to the custom workflow as a lookup parameter (EntityReference). When the Dialog is executed then below error is thrown.

Unhandled Exception: Microsoft.Crm.CrmException: The data required to display the next dialog page cannot be found. To resolve this issue, contact the dialog owner or the system administrator.

Has this process ever worked? Did it stop? My general experience is that making decisions based on a response indicated in a workflow can pretty easily go awry. Could you maybe write the response down to the record in question and then make decisions based on what was written to the record?

Just a thought, let me know if that doesn't make sense.

Brian,

thanks for the response, it works for System Administrator.

I created a new security role and grant all the privileges similar to 'System Administrator' and tested the Dialog, still fails. However, when I logged in as System Admin it work.....

Could it have to do with the process ownership? does the sysadmin own the process in question?

I just hit this exact same error trying to pass a Lookup as an EntityReference to a custom workflow activity as well. Did you ever figure this out?

Just for the record. Had the same problem. I was trying to read an input argument from a Custom Activity Workflow that was null (optional parameter in the CAW specs).

SPECS:

[Input("Description")]
[ReferenceTarget("site")]
public InArgument<EntityReference> inArgument_Site { get; set; }

HINT: Is not required, ie. can be null.

ERROR:

Guid vSiteId = inArgument_Site.Get<EntityReference>(context).Id;

SOLVED

Guid vSiteId = inArgument_Site.Get<EntityReference>(context)!=null?inArgument_Site.Get<EntityReference>(context).Id:Guid.Empty;

Hope this helps someone.

Your plugin code should catch any exceptions and then re-throw an InvalidPluginExecutionExecption so you can see what actually went wrong:

protected override void Execute(CodeActivityContext executionContext) { ITracingService tracingService = executionContext.GetExtension<ITracingService>(); //Create the context IWorkflowContext context = executionContext.GetExtension<IWorkflowContext>(); IOrganizationServiceFactory serviceFactory = executionContext.GetExtension<IOrganizationServiceFactory>(); IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId); try { tracingService.Trace("Starting up"); //Do work. } catch (Exception e) { tracingService.Trace(this.DumpException(e)); throw new InvalidPluginExecutionException(e.Message, e); } } private string DumpException(Exception e) { StringBuilder sb = new StringBuilder(); sb.AppendLine(e.Message); sb.AppendLine(e.StackTrace); if (e.InnerException != null) { sb.AppendLine(this.DumpException(e.InnerException)); } return sb.ToString(); }

I faced a similar kind of issue. Thanks for sharing this code. It helped me a lot to identify the exact cause.
