Welcome to the SL. Gilead's concept is quite flexible and the
implementation ingenious, but there were conceptual obstacles it could
not overcome... i.e. maintaining referential integrity for lazy loaded
objects is a tough problem. GWT itself introducted the RequestFactory
which pretty much does what Gilead used to do and as you noted, things
got a little slow around Gilead also. The reason we finally removed it
is related to moving the SL to Maven which requires all binary
dependencies to be managed by Maven - which Gilead was not.
Regards,
G.
