I believe Ext GWT should support Standard Mode for these reasons :
- "Support for quirks mode (...) may be dropped in future versions of GWT"
- I believe cross-browser compatibility will be better with Standard Mode
- when you build a new webapp with the GWT 1.5 applicationCreator, the generated html file enable Standard Mode. Therefore I (and I guess other users) have tested my web application in standard mode since beta1 release (was already supporting GWT 1.5M2) and not in quirks mode.
Actually, when you generate a new webapp with applicationCreator, it generates the following declaration :
I note that both Explorer and Mail demo both run in Standards mode.
In Explorer and Mail demo, it is not the same :
