I've developed a-sync plugin for updating some fields. But it gives me exception. I've tried using tracing and I found everything is fine.
Following is my code:
itService.Trace("new_approve:"+entity.Attributes["new_approve"]);
if (entity.Attributes.Contains("new_approve"))
{
toApprove = (bool)entity.Attributes["new_approve"];
if (toApprove == true)
{
itService.Trace("Checking if it contians guid");
if (entity.Attributes.Contains("new_contactsguids"))
{
itService.Trace("Guid:" + entity.Attributes["new_contactsguids"]);
listGuids = (string)entity.Attributes["new_contactsguids"];
arrGuids = listGuids.Split(',');
foreach (var guid in arrGuids)
{
visitation.Attributes["new_2015agencyvisitationchecklistid"] = new Guid(guid);
visitation.Attributes["new_checkliststatus"] = option;
visitation.Attributes["new_approvedbydistrictmanager"] = true;
service.Update(visitation);
}
}
}
}And here is the Exception:
