Incremental has an amazingly long tail... While in Bhopal, I did make some progress, but nothing new to show. Just a bit of stuff here and there. Here is what I did
- Discovered spring API to handle exceptions. Much better than the interceptor I wrote. The problem was, the exceptions did not bubble upto the interceptor if I just let them keep going up... So here comes a little help from Spring org.springframework.web.servlet.handler.SimpleMappingExceptionResolver. Nifty little helper. All I did was to extend it and it did exactly what I wanted from my exception handler, which is if its a runtime exception, don't catch it till it reaches the top. I tied this up with AfterThrowing advice, which collated all the important information about method arguments and logged it all together in one place. It worked. I then went around removing try-catch from all the DAOs. At the end of it, I now have a custom 404 and error page along with some useful logging.
- Improving on jqgrid. Though I did get most of the information to look okay, there were some pieces, that did not look okay. So spent some time cleaning up JQ grid. For example, put the navbar on top as well as bottom. Putting "View x of y" etc.
- Changed the Tag Transaction Page to show actions only when you check on any of the loaded transactions.This proved tricky. It's true. If you have a page that does a lot of stuff, you will go crazy untangling the permutations. It seems to have stabilized for now. But I'm sure, it'll change again.
- I also introduced modal for loading. I used jqueryui dialog for the purpose. For the loading icon, I found a very useful site http://ajaxload.info/. Truely useful. My need is simpler than what dialog offers. Let me see how I can strip it down.
