We reproduced the problem. The source of the problerm is in dbExpress implementation. You can check it by using standard driver. ClientDataSet doesn't use connection to server to get detail values on master navigation.

This is error in Borland's ClientDataSet code. We can't advise any method
to avoid it.

How about your product MyDAC?
If the problem caused by cds and no solutions, can I switch to MyDAC?
Is it can solve it?

Yes, migration to MyDAC would solve the
problem, because source of it lies in dbExpress technology. You can check it by trying MyDAC trial. You can download it for free from our site.
