Since you seem desperade, I give you some (stupid?) ideas, but I did
not think about them the necessary time.
Maybe the detail query is simple cose. Query.CommitAction maybe is
caClose, you open it when you create the datamodule, after a commit it
gets closed and the second time you open the form it does not work
anymore.
With the debugger (ctrl+F7) inspect the value of some dataset's
property. Add some IBO bars on the form and chain them with the
datasets just to have a visula clue of what is carrying on (tansaction
bar, dataset bar). Let me know.
