Well, nothing

We've got no reply yet. Should have marked it as needs review, however we didn't have that ability, like permissions or some fun stuff like that. Anyway, it's submitted for review now. Fun.

Done... or are we

We submitted our patch. We'll see if it gets accepted.
Goooooooooooooo openMRS!
Ticket 1150

Irrelevant Post 2

This bears absolutely no relevance to OpenMRS but watch it anyway.

Win.

Completely Phased Out

Soooooooo... we got an email from Darius. He was actually quite helpful, however the first part of the email was troubling. Apparently CohortReportsFromControler has been completely phased out due to a better reporting module. Well... woulda been nice to know. Anyway,
The helpful part was that if we still should complete this task, we found out some good stuff about the refactroing that we're doing. It seems that the onSubmit method we pulled out needs to be pulled out, however they just want the meat of the method pulled out. They would like it if the method onSubmit stayed in place even though it isn't called by anything outside cohortReportsFormController. That's obviously doable, so I'm not really all that worried if Darius says he wants it done that way for 100% real. Also, they want the method itself broken down more... or refacored. Bad a. I can finally do what I've been trying to do all semester.
Freakin WOOT.
The End.
For Now.
Or IS ITTTTTTTTT????!!!?!?!???!?!?!!!!!
Ya, it is.
Bye.

Success

So we got CohortReportFormController refactored successfully. See code below:

Frustration

I'm getting more and more frustrated with this, but hopefully we're almost at an end with the problems. Today we'll be refactoring the code in yet another build. I'll post the results.

Debugging, working, having a blast

So while David looks at roller coaster rides, I'm working on getting debugging working. Wootzorz!

Refactor Success... I think.

So I refactored the code. But I'm not 100% sure if I refactored it flawlessly or not because there's an error when we compile reportingcompatibility that has nothing to do with the new code. It's a shame. This stuff is so much fun.

Progress is limited

Trying to get the cohort reports module to work is frustrating. We've got our ideas in order on how we're going to start refactoring, but we need to get OpenMRS 1.4 to work since Cohort Reports hasn't been updated to work on either 1.5 or 1.6. I've started getting really familiar with the code and as soon as we get the Cohort Reports module working on OpenMRS we'll start hard core refactoring. First we're going to pull out the builder utility, then go to town commenting some other person's code who wasn't terribly fond of commenting. Like as in there are like 2 comment lines for 606 lines of code. Fun stuff. Will update later.

Progress report for today...

So in over and hour I sat in the lab and had to reinstall my virtual machine and reimport openMRS into eclipse. It was fun. Then David and I managed to locate the module and the class to be worked on. I've got everything in place now to start working through the code and refactoring the heck out of it. That'll be started on Friday. Hopefully we can figure out what's going on in the code even though there are virtually NO comments, which incidentally is part of the refactoring we are to be doing. Adding loooooooooooooooooooooooooooooooooooooooooooooooooooooooooooots and looooooooooooooooooooooooooooooooooooooooooooooooots of comments. Woo. Fun stuff. Now off we go to the first star to the right and straight on 'till morning.

The End.

This is random and bears no relevance...

Watch this crap.
The End.

OpenMRS

So I'm working with David on ticket 1150 on the OpenMRS project. I expect it will be more than a blast and we shall have the fun of many lifetimes as we make progress on it. Refactoring is so much fun.
The end
for now...
