Hi Everybody,
i'm new to crm development and i started with developing plugins. In my current plugin I want to update phonecalls, if the contact details change. Most of the code seems to work. But I can not update the phonecall entity via the CRM Web Service.
What i have done so far:
log("Creating new Condition");
ConditionExpression condition = new ConditionExpression();
condition.AttributeName = "partyid";
condition.Operator = ConditionOperator.Equal;
condition.Values = new string[] { key.Value.ToString() };
log("Building Filter");
FilterExpression filter = new FilterExpression();
filter.FilterOperator = LogicalOperator.And;
filter.Conditions.Add(condition);
log("Building LinkEntity");
LinkEntity link = new LinkEntity();
link.LinkCriteria = filter;
link.LinkFromEntityName = EntityName.activitypointer.ToString();
link.LinkFromAttributeName = "activityid";
link.LinkToEntityName = EntityName.activityparty.ToString();
link.LinkToAttributeName = "activityid";
log("Building Query");
QueryExpression query = new QueryExpression();
query.EntityName = EntityName.activitypointer.ToString();
query.ColumnSet = new AllColumns();
query.LinkEntities.Add(link);
log("Building Request");
RetrieveMultipleRequest request = new RetrieveMultipleRequest();
request.Query = query;
request.ReturnDynamicEntities = true;
log("Firing Request");
RetrieveMultipleResponse response = (RetrieveMultipleResponse)service.Execute(request);
log("ForEach");
foreach (DynamicEntity singleEntiy in response.BusinessEntityCollection.BusinessEntities)
{
EntityNameReference refe = (EntityNameReference) singleEntiy["activitytypecode"];
if (refe.Value.Equals(EntityName.phonecall.ToString()))
{
singleEntiy["subject"] = "Meeting with " + contact["firstname"];
log("Try Updating Phone Call: " + contact["firstname"]);
TargetUpdateDynamic updatedDynamicEntity = new TargetUpdateDynamic();
updatedDynamicEntity.Entity = singleEntiy;
UpdateRequest updateRequest = new UpdateRequest();
updateRequest.Target = updatedDynamicEntity;
log("UPDATE!!!!");
UpdateResponse updateResponse = (UpdateResponse)service.Execute(updateRequest);
}
}
log("Finished");
After altering a contact in CRM. I got the following error message: "Object reference not set to an instance of an object". The last entry in my log is: UPDATE !!!
Thanks for your help in advance
Chris
