Congrats man!!! NEPA represent (woot woot!)

Seriously though - good to see they stacked the deck with THE subject matter expert in our community on XPages.

@Vanessa, Lothar's issue was that he only had one value being returned and needs to do an @Explode() to force it into an array.

The only serverside script being executed would be the @DbColumn on the page load. I would try a different browser. I have not seen anyone else post this issue on the forums, so I believe it is an isolated incident. If you want me to take a look, you can send it to me. My email can be found here: { Link }

PS:
the type ahead doesn't works on my browser in discussion DB 8.5 from IBM too (on the Tags-field is type ahead enabled ).
Even yesterday I saw the feature working by one college.

Is it possible, that it is a server-side problem?
any tasks or settings must be enabled ...

hi,
thanks vor good blog.

but I have the same behavior as Lothar, static values are successfully but computed via @dbcolumn doesn't works.
and I can't open the xpages in your example DB in the browser.
Error 403.
DB is normaly copied to server, ACL is copied too, so the default user have a manager access.
Did I something wrong ?

thanks..Vanessa

Hi John,
This worked for me i forgot to copy the dbjcc_license_cu.jar.
Thank you for the fast reply.

Hi Vayasin,

You can find instructions on page 2 of the article. Here's a snippet:

You will need to copy the following db2 jar files from the DB2 installation directory "SQLLIB\java\db2jcc.jar" and "SQLLIB\java\dbjcc_license_cu.jar" to your "Domino\xsp\shared\lib" directory. There might be another way to reference the jar files by editing the Notes.ini, but this works too.

This comment is not about JavaScript calling Java, but I didn't find a relevant post in the site, so I just posted it here.

After switching perspective from Domino Designer to Java, I found that all the form/view elements are just XMLs now, this is also a new change of Domino 8.5, correct? Does it mean that I can manually modify it if I know how to? Besides, if that's true, then we might be able to drop TeamStudio/CIAO version control system for NSF development, and adopt Subversion or ClearQuest, where we even can implement code merges, this will be another good news....

Thanks.

This is a question not about Javascript to call Java, it is about something else. But I didn't find a post that is correlated, so I just posted my question here.

You know, after I switched to Java Perspective, I found that all the form/view elements are shown as XMLs, then does it mean that I can edit them manually(if I know how surely). This will also lead to some changes to Version Control System of DDE8.5 development system. Previously, we've to use something like TeamStudio/CIAO, so now we can use Subversion/ClearCase, is that correct? We can also even able to do form/view elements merge sometimes. If this is true, it is really great news.

Thanks.

Dear John, I am also getting the error:
classnotfoundexception:com.ibm.db2.js.db2driver
And I used your database, can you explain to me how to add the db2driver to the domino server?

@Lothar, though we spoke via email I just wanted to respond here for others who may have the same issues:
- the partial page refresh options is located on the events tab, on the right hand side. Depending on your resolution, you might need to scroll to the right to see the options.

- @DbColumn or @DbLookup, if there is only 1 result the @formula does not return a list , a js array type, but it returns a string. You might want to always wrap the result with an @Explode(). Lothar reported this to IBM as a potential bug.

Thanks for your introduction on the Xpages of Lotus.

Hi,
thanks for your numerous and very helpful examples, too bad I only found them today; would have saved me some trouble in the past few weeks...

OK, 2 questions:
- re: partial refresh: having installed Beta 2 I can't see any trace of the settings visible in your screenshots; the only trace of "partial refresh" I could find so far was in the "pager" control (and that results in strange behaviour if used in conjunction with a DominoView...). HAve there been changes regarding that option as of Beta 2?
- over the last few days I tried and tried to make use of @DbColumn and @DbLookup formulas but without any success:
- - if used for filling the values list of a combo / list box this simply results in error 500 ("HTTP Web Server: Command Not Handled Exception"), although the formula is just THAT simple (@DbColumn(@DbName(),"By Category",1), the view is there, the first column sorted etc.
- - if used with the type ahead feature, the page renders alright, but there's no suggestion made. Type ahead , however, works fine if I enter the suggestions statically as a list
No more ideas on my side, I have to admit...

any help or hint is highly appreciated!

Best regards,
-Lothar

@Philippe, it looks correct but could be the @dblookup is failing. Try hardcoding values in the list instead. That will tell you if it's the lookup or if something else is going on. I'll drop you an email and you can send it to me the db to look at....

Hi,

I have the same problem as Dave, the Ajax type ahead doesn't give me any sugguestions when I type in 's'. I tried on Beta 1 of D8.5 and later on upgraded to Beta 2, but still the same problem. Any ideas ?

I also created an empty XPAge with just 1 edit field with the same settings as described above, without any result.

@Nathan, I too was surprised that they had this working. It was introduced with the DP version pre-beta 10. I tested it with the public beta 2 prior to posting about it, just to make sure it made it into this release.

I am not sure how much work was involved with getting this to work....but I am glad they did! It's a great feature.

I also wonder what limitations there might be? I'll have to look into that.

LOL! That WORKS!??!?!

That means there's a local instance of the servlet running. Scary! But also cool.

Man I would not expect that experience to be consistent with what happens on the server if you're doing anything complex. Especially if you have JAR packages or anything similar involved.

John, thanks for your examples. I was just mixing javascript and @Formula in Computed Text yesterday... nice to see more ways to do it in 8.5.

I am trying to understand how xPages with their ability to bind to multiple datasources might also be able to help me validate many "rows" of data which are being saved to separate documents. Being brand new to xPages, I will do your multiple datasources example and see if that leads to a better understanding.

Alexey,

It makes for a clearer example as to how the client side and server side events work together, which is the goal of this posting.

Thanks,
John

Vidyasagar, you can add a custom control in a repeat control. A custom control is basically an XPage itself, similar to a subform in Domino.

The multi-file upload sample is an example of this. Take a look at this post: { Link }

Comment From Vidyasagar

Vidyasagar — Fri, 18 Jul 2008 01:43:34 AM -0700

Nice one. Its working fine. But is there a way to add an X page in the repeat control and get the same functionality?

Comment From Alexey Zimarev

Alexey Zimarev — Wed, 16 Jul 2008 11:41:28 PM -0700

I am sure you're the great developer, but please don't use constructions like:

if (confirm('text')) {
return true;
} else {
return false;
}

Simple
return confirm('text");
would do and in general is better programming practice

Howard,

It's not related to the above comments.

The error should be "db2.jcc" not "db2.jss" so please check the spelling. If the spelling is correct in your code, did you copy the db2 drivers as outlined in part 2?

Regards,
John

Howard — Wed, 16 Jul 2008 02:21:23 AM -0700

John, I get a classnotfoundexception:com.ibm.db2.jss.db2driver on the server when I try the example. Is this related to to the comments above? thanks,

@Dave, I have been using mostly print statements to debug my server side javascript via the console. If you still have issues you can send me the code to take a look at it....I dropped you an email.

I'll look into debugging methods. It might be an interesting topic to blog on.

Comment From Dave Armstrong

Dave Armstrong — Sun, 13 Jul 2008 12:09:16 PM -0700

Any tips on debugging your app if type-ahead just doesn't work?
I set up a basic type-ahead field, matches everything you have shown... but nothing happens in the browser.

I'm sure it is something simple, but with how new xPages are, I haven't yet got a handle on how to troubleshoot problems when it does not work as expected.

Thanks...

@Stefaan. You definitely can, look at the dojo toolkit (there are others too). I'll email you some info.

@Shu, that actually is funny. I should do an example on using themes...maybe soon.

That is a screen shot of the powerpoint presentation that you can download, which has the nice ppt theme...thanks to Microsoft

Excellent resource to preview the feature! I don't see the theme as reflected in your screenshot, though. Could you provide it as part of the download?

Phil,

Thanks. I had followed up with Jo and he explained it further. I appreciate the input.

I'll update the blog entry with the new best practice once I test it.
