Persistent fields

Hi!

I use UniDAC (vers.3.70.0.17) to access Sql Server Database (or Oracle Database) in Delphi xe application.

In my application, I read data by TUniQuery/TDatasetProvider/TClientDataset and I have a problem if query has persistent fields.
My query reads from table with 4 fields, but query has only 3 persistent fields.
If I have a clientdataset linked to this query by datasetprovider, when I active clientdataset, it raises an exception 'Field not found' (field not persistent).
Instead, if I directly active my query, the execution is ok.
Which is the problem?
What can I do to work with less persistent fields than all fields?

Thanks!!

Hello,

I cannot reproduce the problem.
Please send us a small sample demonstrating the problem including a script to create the table to alexp*devart*com.
