BorderStyle in runtime

I created a Panel and a Memo in runtime. When i try to set the borderstyle of those componenets, i get an error message ('E2003 Undeclared indentifier bsNone'). How can i solve this

Are you using the latest TMS WEB Core (v2.5.2.0)?

I just tested it on my side and it works without any issues:

WebPanel1.BorderStyle := bsNone;
WebMemo1.BorderStyle := bsNone;
