Jesse Gallagher open sourced a mimeDominoDocument
data source. Jesse's description:
"
mimeDominoDocument is an XPages component
that acts like a normal xp:dominoDocument data source but does transparent
serialization/deserialization of 'MIMEBean' data via getValue(...) and
setValue(...). This means that stored Java objects can be accessed directly
via EL. For example, if a field in a document contains a List of Map objects
representing line items in an order, the third line item's name could be
accessed like:
<xp:text value="#{doc.LineItems[2].name}"/>
"
The data source uses the class MIMEBean
which is part of the WatrCoolr
project from Tim Tripcony. Tim describes the underlaying concept in his
blog.
In certain scenarios this powerful pattern can be used to work around size
limitations in NSFs. I've used this pattern myself recently and will blog
about it soon separately.
Jesse's additional logic could qualify
for the fourth OpenNTF
development contest where developers
can win five times $1000.
