    Hello All,

    I have a plugin which will be triggered on Create and Update of Contact field. In the Plugin I want to access related (Account) entity. I am able to access this when the plugin is triggered for Create but I get exception for update message at the following step:

    EntityReference accountref = (EntityReference)entity["parentcustomerid"];

    What I think is I need to use is PreImage and PostImage  to compare the values. If this is the case how can I find out weather the plugin is triggered for Create or Update so that I can avoid retrieving PreImage values for Create message?

    Any help appreciated.

    Thanks

    Vikram

    Hi Vikram,

    In case of Update, If you are not updating the parent customer field then you will not get this in to the target. so in this case you need to get this from preimage entity .

    Hope this will help you.

    Hi Vikram,

    The reason for which you are getting issue is target doesn't contain parentcustomerid field. You will always get only those fields in target those are updated or populated while creation.

    You should always check if target contains the field or not before reading.

    if(entity.attributes.Contains("parentcustomerid") && entity.attributes["parentcustomerid"]!=null)

    {

    EntityReference accountref = (EntityReference)entity["parentcustomerid"];

    }

    You can also check MessageName property of Context that will give you the message for which plugin fired.

    HTH!

    Thanks!

    Note even for "Create" you may not always get the parentcustomerid field. If the user does not set the parent customer for the contact while creating the contact you would not get it even in Create.

    You should check for exists in the entity attribute collection before reading it.

    HTH
