"A component named Data already exists"
I have a program using FastReport 3.x, it creates a report dynamically by means of combination os Report Designer, and Borland C++ Builder version 6.
As we upgrade to C++Buidler 2009, we also upgrade toe use FastReport 4.x.
Some problem arosed:
(1) in the fast-script code session memoX.Visible = <variable_yyy>==true; No longer valid, and I had to change to
if ( <variable_yyy>==true ）{
memoX.Visible = true;
} else {
memoX.Visible = false;
}
(2) while in the c++ code, we call frxReportX->PrepareReport( true);
Exception is caught: A Component named Data already exists.

Comments
I ran into this error today and found out that the error was in my sql query.
Running the application in debug mode with Delphi 2007, the first exception was raised by my query component "arithmetic exception or string truncation...". Unfortunately FR doesn't seem to propagate that exception and only returns "A component named Data already exists", in runtime.
May be too late for you, but I'm answering this anyway for everybody else.
