TVirtualExplorerTreeview thrown AV when Active := True; #3

Closed GallaherMike closed 8 years ago

Delphi 10 Seattle Update 1

Use GetIt to install TurboPack VirtualShellTools and TurboPack VirtualTree.

New project Drop a TVirtualExplorerTreeview on the main form Change the Active property to TRUE AV

Digging through the code it looks like the problem is in TCustomVirtualExplorerTree.DoInitNode specifically the line

FreeAndNil(Data.ColumnManager);

is throwing the AV. It looks like the Data.ColumnManager is passing the Assigned check but is not actually a TColumnManager instance so the free and nil

You should download the latest versions from GitHub since Embarcadero doesn't update GetIt in time.
