Don,
I hacked OnglRuntime until it worked, but I don't think I have enough knowledge
of OGNL and Generics to say that it would work in all cases and that it won't
break other parts of it. That's the reason I haven't submitted it as a patch.
However, if you'd like I could create a JIRA (Bugzilla?) issue and attach the
changes (which are described here:
http://forums.opensymphony.com/thread.jspa?threadID=34624&tstart=0) and also a
small example application that demonstrates the problem.
Yes, please create the ticket. Unfortunately, I don't believe there is
anyone left who _does_ have enough knowledge of OGNL to truely vet it :(
In this thread I mentioned I ran into a new issue, one that my OGNL hack wasn't
enough to fix. It turns out that it is not true. In fact, the problem was that
I misconfigured Struts2. Apparently, the ActionMapper is not the same as
WebWork's and using my old xwork.xml configuration wouldn't work. After I fixed
it, the CRUD operations worked fine on Struts2 (thanks to the OGNL hack).
What exactly was the problem with the xwork.xml? I'd like to keep as
much backwards compatibility as possible.

I have deleted the old files (from previous post) and made available new ones, with the
application working properly. If anyone would like to see it, download
http://labes.inf.ufes.br/~vitor/ww_ognl_issue/Cookbook.war and run it. You will need a
HSQLDB server running with a database called "cookbook". The source code is
also availabe at http://labes.inf.ufes.br/~vitor/ww_ognl_issue/Cookbook.tar.gz (the whole
Eclipse project). To see the error, delete the folder WEB-INF/classes/ognl from the WAR
and try the CRUD operations. Last, but not least, I forgot to delete struts.locale=pt_BR
from WEB-INF/classes/struts.properties. Delete it (or change it) so the WebSite won't
appear in Portuguese.
Sorry I can't help further, but if any Struts developer would take this issue
to him(her)self, I'd be glad to assist him(her). I think this is a big issue,
considering that Struts 2.0 will use OGNL and backwards compatibility is taken
very seriously, as has been said.
