I have create a Jira issue here:
https://issues.apache.org/jira/browse/OFBIZ-1723
Included is code to allow you to create a ftl/widget based screen to allow
users to move through an arbitrary ordered list using next and previous
buttons.
This code creates a self-referencing hash table. The entries are removed on
a timer after 5 minutes and the class is garbage collected. It would be way
nicer to be able to have a listener on the servlet controller so that when
the user moved to a different url base, the container could kill itself.
Alas, I can find no such interface and would love to hear from someone that
knows of a way to do this. Fortunately, the unused overhead is under a
hundred bytes and only hangs around for 5 minutes.
This could be improved on very large tables on some DBs using a binary
search in find() instead of the current sequential one. However, the last()
call required to determine the size reads the entire table on some DBs, so I
didn't think it prudent, and the time consumption on a 10k record table is
more than adequately small in my testing.
The code likely has some tabs in it and does have the opening { on the next
line unlike the ofbiz guidelines, but it is still entirely functional as
well as easier to me to read.
