<br>>By Using gdb, I found out that on the TVirtualStringView side, the FOnGetText(Self, Node, Column, TextType, Text); line (VirtualTres.pas, line 31376) have only one char, while on the original code it does have the full string.<br>
<br>>I tried to convert the string (It's only ascii a-z0-9) to UTF-8 thinking that's the problem, but it is not.<br><br>>I'm using Lazarus 0.9.31 r30000M FPC 2.5.1 x86_64-linux-gtk 2<br><br>>Is there a bug in the new component, or am I doing something wrong ?<br>
