I was going over the patch and it looks like it's out of date already, that is it's not compatible with Beta-6. Also, I'm not sure the implementation is as clean as it could be although when I tried to go in there myself I realized the issue does get a bit complicated.
That is, the mappers and classes need to be completely mapped out in order to find the correct mapping to call from the method invocation. The current patch goes through the generated proxy looking for an interface that contains the method but this method actually uses exceptions as logic... now I'm not sure if this is workable or not but last time I had exceptions as part of normal logic my code ran very slowly... I'm going to poke around the code over the weekend and see if I can't come up with a solution but something tells me the information regarding which mapping to invoke may need to be stored elsewhere... unless I'm just crazy. Also, I ran into an issue when downloading the SVN code. One of the libraries from a test case comes from javax.nio.cs.US_ASCII (sorry if that's wrong don't have access to code ATM) and my IDE (Eclipse w/ SpringSource) is complaining that this is a restricted .jar (the path is resolving to something/something/rt.jar) any ideas as to what could be causing this? Also my maven is refusing to find "org.apache.ibatis:ibatis-3:pom:3.0-SNAPSHOT" from "http://repo1.maven.org/maven2"; but I'm guessing that's likely an issue on my end. Thanks.
