I noticed that in the current cvs of fpc it's implemented the master/detail relation between TDataset(s).
I saw that TDetailDataLink and TMasterDataLink was introduced but I couldn't figure how is supposed to work. I also noticed the abscense of NestedDatasets and DataSetField properties.
They are not yet implemented.
So none of the current TDataset descendants works with Master/Detail schema ?
If some works, can anybody send me a example?
But NestedDataset and DatasetField are ONLY for TClientDataset, and we don't support TClientDataset (yet).
At least TDataset class in Delphi 7 has both properties.
What you must do is
1. Implement parameter support (TParams/TParam is present).
2. Introduce a Datasource property. Whenever the Datasource changes it's data, the detail dataset most close, fill in new parameters, and reopen.
2 is not a problem, this is max 50 lines of code. 1 is the problem.
I'll take a look. Thanks.
Luiz.
