I will explain part of your question.
Properties are from BPEL spec. These are the same as the properties
used for correlation functionality as well. When a property is used
with a variable, the property-alias associated with that property and
that variable (linked by the message or xsd type) can be seen as a
short cut version of an xpath expression.
In other words,
"propertyalias" gives you a query.
"property" links the message and the query.
syntax of variable and property is a like executing that query on that
If you want to execute the same query on the same data (Message or XSD)
type at multiple places in your BPEL, you could use (reuse) the
property rather than trying to generate the same exact query.
More importantly, this syntax provides easy access to the correlation
IDs defined in the Data. User may want to extract this for various
reasons. Instead of writing the same exact query, Property defined for
correlation can be used here as well.
The other part of your Q regarding configuration,
If you have properties defined I think they will show up. But you need
to get the latest builds. This feature is complete, I believe, later
than the build you use. If you post on nb-entpack alias you may get
more accurate information on the configuration
