Re: Inserting a value into a XComponentContext

OK, I've worked it out. What happens is that
comphelper::getProcessComponentContext()
is actually getting the concrete class ComponentContext, which implements
XNameContainer and XContainerContext.

All you need to do is to instantiate a new Reference< XNameContainer > like
so:

Reference< container::XNameContainer > xNameContainer( xContext, UNO_QUERY
);

You can then insert and remove properties at will.
