I am not sure about this, Jon.
The property bag being passed in could include properties
(such as local security callbacks) that are not intended for
Could we please leave this in here for now? Thanks.

Subject: [OpenAjaxGadgets] Widget constructors - property bag
As we worked on the reference implementation, we discovered that
there was no need to pass a property bag to the widget constructor, as
we have talked about in the past. The widget can simply call
widgetwrapper.getPropertyValue() for any property values that it needs,
and can make the call to getPropertyValue() at the time when the widget
needs the information. Another approach to getting property values is to
take advantage of the @@foo@@ macro substitution feature by including
In our reference implementation, we maintain copies of property
values on both sides (i.e., one copy in the mashup editor and one copy
in the widget itself), so when a widget calls getPropertyValue(), there
is negligible performance impact. It seems likely that other
implementations would use a similar approach.
Does anyone see any problems with removing the preliminary
section in the spec (i.e., still has red-colored comments) that talks
about passing the property bag to the widget constructor? To me, this is
a vestigial section that no longer makes sense. Here is the section of
the spec that I propose to remove:
If no one objects by the end of the week, I'll remove this
