Plugin's Target missing attributes

Posted on by adam90

Hello,

I have an entity called Student with two attributes - an OptionSet field called Status and a Lookup field called Faculty.

On a record update (Post-Op) I'd like to trigger a plug-in whenever the Status changes to a certain value.

The record to be updated has a Faculty attached to it already.

My code is as follows -

        Entity studentTarget = context.InputParameters["Target"] as Entity;
            new_student student = studentTarget.ToEntity<new_student>();
            if (student.Contains("new_faculty") && student.new_Faculty != null && student.new_Status.Value == 3)
            {
              // some logic
            }

But the Faculty attribute returns null.

P.S. When registering a new step to the plug-in , in Filtering Attributes, I included both Faculty and Status attributes.

What could be the problem here?

Is it because the Faculty doesn't change that the attribute returns null? If so, how can I resolve this problem?

Thank you

RE: Plugin's Target missing attributes

in the update message the target contains only the attributes that changed. If you need to access other fields you need to register an image

RE: Plugin's Target missing attributes

Hi

I would first check if the attribute is passed in the entity image before converting to new_student.

you could try something like this

var hasAttribute = studentTarget.Attributes.Contains("new_faculty")
throw new InvalidPluginExecutionException("Faculty attribute passed? : " + hasAttribute); }

If this exception displays true for attribute passed, the problem is in the mapping to early bound class.
