hi to all, here's the funny thing :

<meta http-equiv="refresh" content="" tal:attributes="content python:'2;/esami/' + context.REQUEST.SESSION['role'] + '/'">

gives a <!-- Page Template Diagnostics Compilation failed TAL.TALDefs.TALError: Python expression error: EOL while scanning single-quoted string (Python expression "'2", line 1) in expression "python:'2", at line 3, column 5 -->

if i remove the ; char all is ok (but obviously the meta-http is not working) .

is it a bug or a feature ? is it well known ?
