Lots of classes implement XInvocation in order to add extra methods and
properties that are determined at runtime. One problem with this is that
when such an object is introspected with the css.script.Invocation
service then that service uses the XInvocation interface directly to
query what methods and properties are supported instead of creating an
XIntrospectionAccess via the css.beans.Introspection service. It looks
like probably all of the current implementations of XInvocation only use
it to advertise the dynamic methods and don’t advertise any concrete
methods provided by any interfaces that the object implements. This
means for example that when the object is accessed by pyuno, only the
dynamic methods and properties can be used.
This patch adds a helper class that can be used to help implement
XInvocation in such a way that if a requested method isn’t found as a
dynamic method, it can pass the method call on to the helper which will
use the normal Introspection service to query the available methods and
properties.
