The problem that gives me is that the second generation of the report returns me the following error:
EParseError
Udefined symbol: FirstDataSet."Name"
in file "lr_class.pas' at line 8982
While the first time the report is generated correctly.
The error occurs only with reports connected to a database, and no database works correctly even to succeeding generations to the first.
How can I solve it?
Another question, where do I find the LazReport manual?
