New Revision: 3171
Modified:
mgmt/trunk/wooly/python/wooly/__init__.py
mgmt/trunk/wooly/python/wooly/forms.py
mgmt/trunk/wooly/python/wooly/pages.py
Log:
Make Page rather than Application responsible for keeping global
widget and parameter state.
Introduce WidgetPage, to encapsulate frame-based state preservation.
This way we don't have things like CssPage thinking about that.
Add methods on Page to pass control during widget and parameter
initialization back to the page.
