I noticed that in the Ext GWT documentation (helpful hints in http://www.sencha.com/helpcenter/index.jsp
Doctype: Ext GWT requires the following doctype:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
However, when you use the WindowBuilder wizard it creates a standards mode doctype.
Is this an issue? I would prefer to use the Standards mode, but don't want to encounter any table related problems down the line.
