Xpages error when saving document in different DB in XPiNC - xpages

Question

I am running an Xpages db in XPiNC that I want to use as a "front end" to several other databases in our system. I will store the code in this DB and access the data in other DBs.
When I am trying to do a simple CRUD operation on a form I am getting an error that I cannot explain.

The database that I am getting the data from is not in Xpages, but I don't think that that should matter.

Answer 1

Your datasource defines databaseName="helpdesk.nsf" - in XPiNC it means local replica of the database. You need to use full format, as Paul suggested:
databaseName="yourservername!!helpdesk.nsf"
I recommend to parametrize the server with:
databaseName="#{database.server}!!helpdesk.nsf"
I think validator fails because of "no data" from invalid data source.

Answer 2

Looking at the stack trace, it's failing in Process Validations phase - so checking datatypes for validation / data conversion, and failing on the DateTimeHelperRenderer. It looks like that's pointing to computedField2.
There are two possible explanations:
One of the view entries has a value in column $1 that cannot be converted to a date. This sounds the most probable.
You're hitting the problem I blogged about with partial refreshes and row datasources not available http://www.intec.co.uk/dataviews-and-nested-repeats/. If this is the case, wrapping the calculation with if (view.isRenderingPhase()) {...} will solve the problem. If it's not the case, it will move the error to the Render Response phase.
