Plugin Error message - System.InvalidCastException: Specified cast is not valid.

Posted on by rthompson 1,530

Hi

I can't figure out why I am get this error message System.InvalidCastException: Specified cast is not valid.

I am doing a loop to make copies of detail records.

I am creating a reference to add to a lookup field.

Any ideal what is causing this error message?

                    //Instead of iterating through all the child records and creating one by one we can also use ExecuteMultiple method
                    foreach (Entity retrieve in service.RetrieveMultiple(query).Entities)
                    {
                        //Remove the primary key of the retrieved associated record
                        retrieve.Attributes.Remove("new_selectortemplatequestionid");
                        retrieve.Attributes.Remove("new_selectortemplateid");

                        //Set the primary key value to Guid.NewGuid()
                        retrieve.Id = Guid.NewGuid();

                        EntityReference newselectorTemplateLookup = new EntityReference("new_selectortemplate", selectortemplateId);

                        retrieve.Attributes.Add("new_selectortemplateid", newselectorTemplateLookup);
                        service.Create(retrieve);
                    }

    Hi,

    Are you still getting the invalid case exception or something else?

    Can you try a small sample to create a copy of the record but with just one attribute to copy i.e. foreach record, create a new record and just add one field instead.

    Is working fine when you are running as async?

    RE: Plugin Error message - System.InvalidCastException: Specified cast is not valid.

    Hi,

    I am using a plugin post operation.

    The selectortemplateid is coming from the primary entity that is not committed.  I am using "Aync".

    selectortemplateid = 12bf3c3b-5f2c-e811-80da-005056ba7ce0

    I am creating a new entity and trying to copy detail entity from another entity.

    I am seeing the record in the table.

    The reference is not returning the name to the lookup.  I believe this might be causing my error message.  But not sure.

    If you notice from the image the lookup is not getting creating completely.  The "ExtensionData" is null and the "Name" is null.

    Here is code that I am using.

    EntityReference newselectorTemplateLookup = SetReference("new_selectortemplate", selectortemplateId);
newselectorTemplateLookup.Name = selectortemplatename;
questionTemplate.Attributes["new_selectortemplateid"] = newselectorTemplateLookup;


    Here the primary entity

    Primary.JPG

    I tried to add the "Name" from the Primary but that still did not fix the error message.

    foreach (Entity _entity in result.Entities)
{
  Entity questionTemplate = new Entity(_entity.LogicalName) { Id = Guid.NewGuid() };

  questionTemplate.Attributes.Add("new_name", _entity.GetAttributeValue<string>("new_name") ?? string.Empty);
  questionTemplate.Attributes.Add("new_sectionid", _entity.GetAttributeValue<EntityReference>("new_sectionid"));
  questionTemplate.Attributes.Add("new_questionid", _entity.GetAttributeValue<EntityReference>("new_questionid"));

  EntityReference newselectorTemplateLookup = SetReference("new_selectortemplate", selectortemplateId);
  newselectorTemplateLookup.Name = selectortemplatename;
  questionTemplate.Attributes["new_selectortemplateid"] = newselectorTemplateLookup;

  service.Create(questionTemplate);
}

    I decided to change the code to assign each attribute.

    Still getting the same error message.

                        // Loop through each detail record to copy
                    EntityCollection result = service.RetrieveMultiple(query);
                    foreach (Entity _entity in result.Entities)
                    {
                        Entity questionTemplate = new Entity();

                        questionTemplate.LogicalName = _entity.LogicalName;

                        questionTemplate.Id = Guid.NewGuid();

                        if (_entity.Attributes.Contains("new_name"))
                        {
                            questionTemplate["new_name"] = _entity.Attributes["new_name"];
                        }

                        if (_entity.Attributes.Contains("new_sectionid"))
                        {
                            EntityReference sectionLookup = (EntityReference)_entity.Attributes["new_sectionid"];
                            questionTemplate["new_sectionid"] = sectionLookup;
                        }

                        if (_entity.Attributes.Contains("new_questionid"))
                        {
                            EntityReference questionLookup = (EntityReference)_entity.Attributes["new_questionid"];
                            questionTemplate["new_questionid"] = questionLookup;
                        }

                        if (_entity.Attributes.Contains("new_selectortemplateid"))
                        {
                            EntityReference newselectorTemplateLookup = SetReference("new_selectortemplate", postImageSelectorTemplateId);
                            questionTemplate["new_selectortemplateid"] = newselectorTemplateLookup;
                        }

                        service.Create(questionTemplate);
                    }

    I change the logic to add each attribute to make sure I was not missing anything.

    I am still getting the same error message.

    Here's my new code

                        // Loop through each detail record to copy
                    EntityCollection result = service.RetrieveMultiple(query);
                    foreach (Entity _entity in result.Entities)
                    {
                        Entity questionTemplate = new Entity();

                        questionTemplate.LogicalName = _entity.LogicalName;

                        questionTemplate.Id = Guid.NewGuid();

                        if (_entity.Attributes.Contains("new_name"))
                        {
                            questionTemplate["new_name"] = _entity.Attributes["new_name"];
                        }

                        if (_entity.Attributes.Contains("new_sectionid"))
                        {
                            EntityReference sectionLookup = (EntityReference)_entity.Attributes["new_sectionid"];
                            questionTemplate["new_sectionid"] = sectionLookup;
                        }

                        if (_entity.Attributes.Contains("new_questionid"))
                        {
                            EntityReference questionLookup = (EntityReference)_entity.Attributes["new_questionid"];
                            questionTemplate["new_questionid"] = questionLookup;
                        }

                        if (_entity.Attributes.Contains("new_selectortemplateid"))
                        {
                            EntityReference newselectorTemplateLookup = SetReference("new_selectortemplate", postImageSelectorTemplateId);
                            questionTemplate["new_selectortemplateid"] = newselectorTemplateLookup;
                        }

                        service.Create(questionTemplate);
                    }

    Hi ,

    Could you please try with this - 

                            Guid selectortemplatequestionid = new Guid();
                        Guid selectortemplateid = new Guid();

                        EntityCollection result = service.RetrieveMultiple(query);
                        foreach (Entity _entity in result.Entities)
                        {

                            EntityReference questionlookup = (EntityReference)_entity.Attributes["new_selectortemplatequestionid"];
                            selectortemplatequestionid = (Guid)questionlookup.Id;
                            EntityReference templatelookup = (EntityReference)_entity.Attributes["new_selectortemplateid"];
                            selectortemplateid =(Guid)templatelookup.Id;
                            questionlookup.Id = new Guid();
                            EntityReference newselectorTemplateLookup = new EntityReference("new_selectortemplate", selectortemplateid);
                            _entity.Attributes.Add("new_selectortemplateid", newselectorTemplateLookup);
                            service.Create(_entity);

                        }

    Hope this helps.

    Hi Temmy,

    I am not removing attributes that I don't need.  I am removing and adding back.

    I am trying to understand your logic.

    Would you have an example of using ExecuteMultiple.
