Ok I understand the problem. I wasn't up to date with the latest
definition of properties. If the current interface to properties is not
workable then we can always feed that back to the spec group. Anyho...
I think what we need to do is
1)create a DataFactory for the properties and populate it with the types
required for the properties (basic xml types will be there by default
but
any user defined complex types will have to be defined in a schema
somewhere
so lets stick to simple types for now).
2) When loading the definitions of the properties from the componentType
we need to create a new SDO Type for properties associated with this
component and add it to the DataFactory. So we would do something like:
dataFactory->addType("someNamespace", "componentProperties", ....)
dataFactory->addPropertyToType((<propertyName>, <propType>.... for
each of
the properties defined)
3) create a DO of "someNamespace", "componentProperties" type and
save the
DOPtr in the Component defintion in the model
4) For each property set
propertyDO->set(<propertyName>, value)
5) ComponentContext::GetProperties will return the propertyDO from the
Component
voila!
So we need to create a datafactory per componentType I think.
