    Hi All I am trying to pass in a global optionsetvalue to a workflow activity but keep getting errors:

    Code

    [RequiredArgument]
        [Input("Process type")]
        [AttributeTarget("bi_workflowprocessmapping", "bi_processtype")]
        public InOutArgument<OptionSetValue> ProcessTypeOS { get; set; }

    I am passing in a static value also, not a dynamic value so the field should not be null

    Getting the following error

    Unhandled Exception: Microsoft.Xrm.Sdk.InvalidPluginExecutionException: Exception CloseAllCasesForOrgProcessType Activity: System.ServiceModel.FaultException`1[Microsoft.Xrm.Sdk.OrganizationServiceFault]: An exception System.FormatException was thrown while trying to convert input value 'Microsoft.Xrm.Sdk.OptionSetValue' to attribute 'bi_workflowprocessmapping.bi_processtype'. Expected type of attribute value: System.Int32. Exception raised: Input string was not in a correct format. (Fault Detail is equal to Microsoft.Xrm.Sdk.OrganizationServiceFault).

    Really not sure where to go from here. Please help,

    Regards

    nick

    Thanks

    HI nick,

    try to pass an Int32 as follows

    public InOutArgument<Int32> ProcessTypeOS { get; set; }

    and pass the integer value of the optionset.

    Your code does look correct, as parameter should be defined as

    public InOutArgument<OptionSetValue> ProcessTypeOS { get; set; }

    Is the error thrown within your code, or before it gets to your code ? To test this, check if you still get an error even if your code never uses the attribute.

    Have you published the option set - I could imagine you getting the 'Input string was not in a correct format' error if it's not been published. Also, if you use language packs, I'd check you have labels for this option set for all languages

    Hi Nick,

     Is your parameter inOut or in? Please try the following?

    // Declaration
[RequiredArgument]
[Input("Process type")]
[AttributeTarget("bi_workflowprocessmapping", "bi_processtype")]
public InArgument<OptionSetValue> ProcessTypeOS { get; set; }

//Inside protected override void Execute(CodeActivityContext executionContext)

var processTypeOS = this.ProcessTypeOS.Get<OptionSetValue>(executionContext);
if (processTypeOS.Value == 100000000)
{
}

    Regards,

    To get the text value you can user following method 
    public static string GetoptionsetText(string entityName, string attributeName, int optionSetValue, IOrganizationService service)
        {
            string AttributeName = attributeName;
            string EntityLogicalName = entityName;
            RetrieveEntityRequest retrieveDetails = new RetrieveEntityRequest
            {
                EntityFilters = EntityFilters.All,
                LogicalName = EntityLogicalName
            };
            RetrieveEntityResponse retrieveEntityResponseObj = (RetrieveEntityResponse)service.Execute(retrieveDetails);
            Microsoft.Xrm.Sdk.Metadata.EntityMetadata metadata = retrieveEntityResponseObj.EntityMetadata;
            Microsoft.Xrm.Sdk.Metadata.PicklistAttributeMetadata picklistMetadata = metadata.Attributes.FirstOrDefault(attribute => String.Equals(attribute.LogicalName, attributeName, StringComparison.OrdinalIgnoreCase)) as Microsoft.Xrm.Sdk.Metadata.PicklistAttributeMetadata;
            Microsoft.Xrm.Sdk.Metadata.OptionSetMetadata options = picklistMetadata.OptionSet;
            IList<OptionMetadata> OptionsList = (from o in options.Options
                                                 where o.Value.Value == optionSetValue
                                                 select o).ToList();
            string optionsetLabel = (OptionsList.First()).Label.UserLocalizedLabel.Label;
            return optionsetLabel;
        }
