Entity (Target) is not bring PostImage values.

I have a plug-in that is attempting to read a custom entity and create a history record in a related entity. However, I am getting no values in my Target entity. Here is the "Execute" code:

ITracingService tracingService = (ITracingService)serviceProvider.GetService(typeof(ITracingService));

IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));

if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)

{

Entity entity = (Entity)context.InputParameters["Target"];

if (entity.LogicalName != "lena_dlp")

return;

///my code goes past here so I AM getting the proper entity from the form.

IOrganizationServiceFactory serviceFactory =

(IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));

IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId);

try

{

Entity dlphist = new Entity("lena_dlphistory");

///this next line is what causes the Exception.

dlphist["lena_dlp_sn"] = entity["lena_dlp_sn"];

When looking at the "entity" object, the values are non-existent. I can look at entity.Attributes[0] or any other notation and get no results.

What am I missing?

Hi Don,

In the title you said postimage, but in your code nothing I found the code lines related to Post Image..

To get the postImage you need the code something like:

if (context.PostEntityImages.Contains("PostImage") && context.PostEntityImages["PostImage"] is Entity)

{

//get postImageEntity

Entity postImageEntity = context.PostEntityImages["PostImage"];

}

"When looking at the "entity" object, the values are non-existent. I can look at entity.Attributes[0] or any other notation and get no results."

But if the entity object is null, the code will not pass this:

if (entity.LogicalName != "lena_dlp")

Instead, it will 'return' and then stop execute your plugin.

But, it seems it pass the code so, the 'entity' is not null.

Can I know you register in what message event?

Hi Aileen - thanks for the reply.

Let me clarify. The entity I am looking to get values from is the "lena_dlp", which is being returned. My reference to the PostImageEntity was misstated. What I meant was I was looking for post-process values (after the update was completed) so I'm looking for the PostEntityImage values. At a later date I will also look for the PreEntityImage values, but that's for another day.

In other words, I want to read the values from the updated record in "lena_dlp" and save those values in another entity. My program errors out when I try to read the values from the "lena_dlp" instance.

My plug-in is registered for the "Update" event for the lena_dlp entity.

Does that help clarify things?

Hi Don,

Update event Post or Pre?

///this next line is what causes the Exception.

dlphist["lena_dlp_sn"] = entity["lena_dlp_sn"];

I am curious what exception actually you got if you run the plugin?

Is that Object reference not set, Null value or anything else?

Because I worry that the Null value is not coming from entity, but instead, coming from

attribute lena_dlp_sn in this: entity["lena_dlp_sn"];

So, better you check if entity.Contains("lena_dlp_sn")

Or you can use GetAttributeValue()

There is a great example from Ben Hosking:

crmbusiness.wordpress.com/.../crm-2013-using-entity-getattributevalue-instead-of-entity-contains

And my next question is: does the "lena_dlp_sn" attribute value was updated? Because if not, it will not give you any value unless you use PreImage entity.

Thanks.

Hi Aileen - that got me farther.

I changed the processing to Pre- and used the Entity.GetAttributeValue() method. Now, it looks like this:

Entity dlphist = new Entity("lena_dlphistory");

dlphist["lena_dlp_sn"] = entity.GetAttributeValue<string>("lena_dlp_sn");

dlphist["lena_name"] = entity.GetAttributeValue<string>("lena_dlp_sn");

dlphist["lena_dlp_statusid"] = entity.GetAttributeValue<OptionSetValue>("lena_dlp_statusid");

dlphist["lena_dlp_statusdate"] = DateTime.Today;

dlphist["lena_dlp_statusreason"] = "just because";

But I get an exception when trying to create the record:

service.Create(dlphist);

The error message reads:

An event was requested after the recorded event queue has been completed

Ideas?

Hi Rengeek,

Are you sure you have this field:

dlphist["lena_dlp_statusreason"] = "just because";

I never encounter that error.

But, for history, I recommend you to register on Post Update....

Please comment the codes and change to minimalist code like this:

Entity dlphist = new Entity("lena_dlphistory");

dlphist["lena_name"] = "Hello Rengeek";

service.Create(dlphist);

Because I really want to know what exactly makes this error.

Is that because of wrong assigned attribute value or not.

Thanks.

Hi Aileen,

I have other "Business Required" fields in the Entity. Won't that make your code fail?

Hi Rengeek,

No...Through plugin it will be skipped.

Unless you create through UI and open the form (after create through plugin), it will give you error.

Just to make sure that you can create the history.

Hi Aileen,

New code:

Entity dlphist = new Entity("lena_dlphistory");

dlphist["lena_name"] = "Rengeek";

service.Create(dlphist);

Same error as above.

First, I added code to try and create an account record:

Entity account = new Entity("account");

account["name"] = "Fourth Coffee";

mAcctId = service.Create(account);

Same error:

Then I removed the service.Create statements and it functioned without error, but, of course, it didn't create the record.

I looked at the service object and it seems valid - at least it's not causing an error, but I can't really see any values. When I try I get the following:

Count = Function evaluation disabled because a previous function evaluation timed out. You must continue execution to reenable function evaluation.
