Dialog is broken. Window works ok though.

(SC_SNAPSHOT-2011-06-14/Pro Deployment 2011-06-14)

 new Dialog().show()

Fixed. Note this only affects a custom Dialogs with no buttons, an odd edge case. Any other use of Dialog is fine.

Weird. My code had buttons in it - would it matter if they were embedded in another layout? I was using addItem and adding a VLayout.

Also, another case of developer falling asleep while writing documentation:
http://www.smartclient.com/smartgwtee/javadoc/com/smartgwt/client/widgets/Dialog.html

ok, I guess I should be using setToolbarButtons

That’s already corrected and the developer in question is receiving treatment for narcolepsy.

I just bookmarked the up to date javadoc - I keep looking at the old ones by mistake. (takes memory pills)
