Summary0006485: jvInterpreter cannot handle repeated uses
DescriptionTestScript uses 'lib\Lib1' and 'lib\Lib2'
Lib1 uses 'lib\Lib2'

The jvInterpreter throws a duplicate identifier on whatever the first identifier is (constant, variable, or function) in Lib2.
Additional InformationThis can be fixed by adding a single line of code to jvInterpreter.pas -> procedure TJvInterpreterUnit.ReadUnit (starting at line 7964):

procedure TJvInterpreterUnit.ReadUnit(const UnitName: string);
  OldUnitName: string;
  OldSource: string;
  S: string;
  if FAdapter.UnitExists(UnitName) then
  FAdapter.AddSrcUnit(FCurUnitName, '', '');
  FAdapter.AddSrcUnit(UnitName, '', ''); // the line of code added

Adding this line of code simply prevents the jvInterpreter from attempting to call InterpretUnit on the same unit twice.
TagsNo tags attached.

I need to correct something here. The example I gave is actually a trivial example which can be resolved by changing the uses line to just

uses 'lib\Lib1';

A better example:

Lib1 uses Lib3
Lib2 uses Lib3


uses 'lib\Lib1', 'lib\Lib2';

Will always lead to a redeclared identifier error.

Hi obones,

Sorry but I've moved on from using Delphi/Jedi for development for my applications and won't be able to provide an example.

As asked before, could you please provide the zipped sources of a sample application showing this?
