Updated CRM 2013 On premise breaking plugin code RRS feed

  • Question

  • Hi,

    I have CRM 2013 on premise environment. Today i started installing the rollup's. It went fine when i installed UR1, UR2 and UR3 and my plugin executions is working as expected. After i installed SP1 and UR1 for SP1, my plugin code is breaking.

    In my plugin i had code to retrieve option set text value. The below is the code

    private static string GetOptionsSetTextForValue(IOrganizationService service, string entityName, string attributeName, int selectedValue)
            {
                try
                {
                    if (service != null)
                    {
                        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 == selectedValue
                                                             select o).ToList();
                        string optionsetLabel = (OptionsList.First()).Label.UserLocalizedLabel.Label;
                        return optionsetLabel;
                    }
                }
                catch (Exception ex)
                {
                    CustomServiceManagementPortalException customEx = new CustomServiceManagementPortalException(string.Format(CultureInfo.InvariantCulture, "Fetching option set label for fieldname {0}, value {1} and entity {2} failed.", attributeName, selectedValue, entityName), ex);
                    throw customEx;
                }

                return string.Empty;
            }

    In this function my code is failing with error "An unexpected error occured.

    I am not able to figure out what went wrong. Can anyone suggest me some solution.

    Regards,

    Kishan.

  • Hi,

    It's sort of hard saying anything with that error, do you have to option to enable tracing and post the message there instead?

  • Personally I don't like  this type of constructions. 

    IList<OptionMetadata> OptionsList = (from o in options.Options
                                                             where o.Value.Value == selectedValue
                                                             select o).ToList();
                        string optionsetLabel = (OptionsList.First()).Label.UserLocalizedLabel.Label

    with the OptionsList.First() you assume that there is always a list containing data. This is a wrong assumption and this might be causing the exception. Furthermore  (OptionsList.First()).Label could result in a null value

  • The UserLocalizedLabel value can differ based on the context in which the plugin runs. This is a possible source of the error. Under what user context is the plugin step registered ?
