In this show Steve Zavocki, a new contributor and a CUSTOMER, comes on the show to give a demo on using the view controller to launch attachments.
He blogs at http://notesspeak.blogspot.com. Don’t miss his about page with details how he got started with XPages. Great story there.
In this show he and I mention Stephan Wissel’s blog post on working with Attachments. That link is here:

Thanks!
UPDATE: Don’t miss Steve’s blog post about this technique.

In this show Jesse Gallagher, a great new contribitor, comes on to give us an over view of using Java Controller Classes to help seperate your business logic from your XPage. By moving your logic outside of the XPage you get much cleaner XML source for your XPage.
If you’re new to the thought of using Java inside XPages, I’d suggest don’t focus on the actual syntax that Jesse’s using here but the overall concepts. This is very similar to using Lotusscript custom classes to hold your business logic so you have cleaner agents and view buttons.
Hope you like it.
In this show an Fredrik Norling, and IBM Champion and awesome develolper, comes on NotesIn9 for the very FIRST time!
Frederik, is going to give us a really good and indepth demo on using the new SSJS debugger of Designer 9.0. This isn’t just a getting started, but an indepth guide on using it. Not to be missed!
I also announce my next “event” in the show. It’s called “XPages Mobile Madness”. Basically I want to get a bunch of mobile related shows on. I’ll talk about this more in a seperate blog post.
Thanks for watching!

In this show I answer a question from a poster on the XPages Forum. Ursus Schneider posted that he was having a problem with Arrays (http://www-10.lotus.com/ldd/xpagesforum.nsf/topicThread.xsp?action=openDocument&documentId=646EB71744203F5C85257B38006321C2) but when he sent me a small sample to look at he had actually was having problems with working with comboboxes and partial refreshes.
So in this show I take a look at the sample I was sent and dissect it. I’ll try and show you how it was originally coded and what the current problem that Ursus was having it. I’ll fix that but then take a more indepth look at trying to modify the original code so it’s more on the lines of best practices.
Coding is an art, and I’m only so good at it myself, but hopefully this will be a contructive look at some possible ways to improve things via a code review. I thank Ursus for sending me this and letting me using the discussion on the show.
One of the main reasons I wanted to do this example, was I thought pretty early on that I could work in an example that I’ve been trying to get on the show. I wanted to demonstrate how you can return multiple values from a document from 1 SSJS function. So instead of doing multiple lookups you might be able to do more at once.
Anyway – hope you like the show. This should be a good one for people newish to XPages.
P.S. Theres like 3 seconds of black at the beginning of this video. I’ve no idea what I did there. Sorry about that.
I got a question today from someone who looked at the slides that Kathy Brown and I did from IBM Connect”
while reading your presentation XPages: No experience Needed I noticed the your screenshot of the layout control differs from what is displayed here in designer.
we downloaded openntfextensions (ExtensionLibraryOpenNTF-853.20121022-1354) and installed ’em (test/-developer-server and developer-client). everything went fine and layout control was just like shown in your presentation.dragging the layout control to the panel surface opened up the config dialog. we did some playing around but because of official ibm support for upgrade pack 1 we decided to jump on the upgrade pack train and give it a try. but it seems as if upgrade pack 1 is a little bit outdated in comparrison to openntfextensions – e.g. the layout control doesn’t show a config dialog.would installing upgrade-pack 2 improove things and also update extensions controls like layout or do we have to stick with upgrade pack 1 and live with it?
perhaps you can help and give us a short hint. thanks in advance.
Here’s my personal opinion of Upgrade Pack vs. Ext. Library.
Always use Ext. Library.
Yes – Upgrade Pack is “Supported” by IBM but I honestly don’t know what that means. Sure you can make a PMR but I’m not aware of IBM providing hotfixes for bug fixes for the upgrade pack. Honestly I’m not personally aware that there will be an Upgrade Pack 2. I THINK there’s an “Upgrade Pack 2” that’s specific to Traveler. I don’t know of a second Upgrade Pack for the Ext. Library stuff for Domino 8.5.3. I think that the path is to go Domino 9 which pretty much has it built in. I could be wrong on those points though.
But I do know that even though Ext. Library “is not supported”, it has been getting fairly regular bug fixes and updates. I believe Upgrade Pack 1 came out late 2011. Just checking the OpenNTF project I can see that there were 7 releases of Ext. Library since then. Most of those releases are bug fixes I think. So to me, I think Ext. Library has much better real support.
Now I’m a developer at a private company, and we put Ext. Library on all our servers. Honestly I’ve never downloaded or touched Upgrade Pack 1. Granted, at my company I have the luxury of working with Declan Lynch, a top Domino admin. But even so, I can’t imagine a situation where I would lean towards Update Pack 1.
Now there is more “risk” with Ext. library in some cases. At one point the Ext. Library changed some names and that might have caused some people some problems. We use Ext. Library heavily and I don’t think we were heavily impacted by that. But even though something got changed, so what? Apple, and Microsoft, and Google change “supported” things all the time. So I don’t see a big difference here.
I hear from friends and others that they use Upgrade Pack 1 because “customers require support”. I just don’t know what that support really means. What’s sillier is that some of the same people that run Upgrade Pack 1 for IBM support also ask how to install the experimental pieces from Ext. Library for Relational Database support etc… That makes no sense to me. Now they’re asking to run unsupported software in and unsuported configuration.
Domino 9.0 is being released on the 21st it seems. That has most of the core Ext. Library built in. My recommendation would be to move to that as soon as possible. I know we are. I believe there will then be an Ext. Library specific to 9.0 but that’s just a guess. I’m anxious to hear the Ext. Library plans for 9.0 myself.
It was funny when Kathy and I did that presentation. She used Upgrade Pack 1 because as a consultant that’s more desirable to her. I was on Ext. Library and we did see some issue as I had bug fixes that she did not. Was a bit of a pain really. But don’t tell her that! haha
I’m blogging this in case anyone wants to comment and you can get more opinions.
Hope this helps.

In this show John Jardin returns with a good demonstration on how to not only install the free Domino Designer, but how to actually find it on IBM’s website. He even show’s you how to get started creating a database.
Also a big Happy Birthday to a great person and NotesIn9 contributor – Mr. Russ Maher!!!
In this show Paul Calhoun returns with a great video on how to get started using Apache FOP to create PDF’s from XPages. Apache FOP has potentially better licensing terms then iText which has been mentioned on some previous NotesIn9’s. So it’s something you might want to look at for PDF creation.

NotesIn9 Update
Just to give anyone a heads up as someone asked me about NotesIn9 and new shows.
I wanted to get more shows out by now, but I’m in the middle have some heavy traveling as I’m training people on how to use this XPages Application I’ve been working on for the day job. It uses Mobile controls and a bluetooth barcode scanner so it’s pretty cool. At least I think so. haha
As I type this I’m heading out in 30 minutes for 2 days off with the family. Then Saturday I come back and need to cook 3 Porks and a Brisket for my son’s schools “International Food Fesitval” on sunday. I’m doing a BBQ booth because really… what’s more international then Texas?
As soon as I have time I’ll have more new shows coming. I’m probably sitting on 4-5 shows still that have been delivered by great contributors that I just need to wrap up and get out. And I keep getting emails from people with more to offer. So I’m really sorry I’m having trouble keeping up but hope to clear the backlog as soon as possible. There is great stuff coming. And even more new contributors coming!!
If anyone has emailed me and I’ve not responded – please feel free to email me again. That’s hard to keep up with as well but I do try and respond to everything I get.
So as always thanks for watching. The best is yet to come!!

Declan is blogging about XPages!
Declan Lynch was the first real blogger to really share XPages Information. Back in 2009 he came out with a legendary 54 part series that for the longest time was the best XPages information available.
His blog is www.qtzar.com and he’s blogged today about XPages in Java and I believe has more ready to go for the next several days. The first one is here:
http://www.qtzar.com/getting-to-the-java-roots-of-xpages-part-1/
I’m posting this since Declan to drive visibility to it as he’s not listed on PlanetLotus.org and I didn’t see it show up on CollaborationToday.info
I suggest you keep an eye on his blog.
