Master/Detail lookup - losing detail field

 Master/Detail lookup - losing detail field

This is the situation (local database, D5):

Master/detail tables in a datamodule, linked by the master's primary (only)

Then, another dataset, containing (among others) two fields a master_code
and a detail_code, which correspond to the primary keys in the master table
and the detail table.

Of course, I don't want to display the codes when manipulating my dataset,
so I add two lookup fields (master_alpha and detail_alpha). So far so good.

Except that the detail lookup field does not get synchronized as you move up
and down the dataset (master is OK). The same problem occurs whether I
display the alpha fields in a dbgrid or in a dblookupcombobox. Master works
OK, but detail most of the time just shows blank (not found). The
detail_code contains a valid code for this master. But the lookup mechanism
does not find it in the dtail table.

Any ideas? Thanks.
