Re: WOWODC 2015

2014-12-28 Thread Tobias Janz
Hi all,

i'm realy glad about WOWODC in Germany.
I'm looking to come to the conference. Hopefully my company will pay the
tickets for me. But to get them to that point i need to know which
presentations will come up.

In my company we don't use WO, but there is a lot of cool stuff which can
be integrated. The last weeks i've done some testing with jnario. If
someone is interested in it i could do a session about jnario (jnario.org).
The main focus of this framework is to have executable specifications and
no seperation between testspezification and testexcecution.

Looking forward to WOWODC 2015

Tobias

AjaxAutoComplete in Tables

2014-05-08 Thread Tobias Janz
Hi all,

i have a table with a loop for the line (tr). Each line displays one
entity. I need to edit field of the entity directly in the table. One of
this field is an AjaxAutoComplete. I so use this component in some other
parts of my application and it works fine. But now in the table i have some
problems.
First the choices are not a lot so i used isLocal=true. In the table with
these option the div with the choices don't show up when the component gets
the focus, outside the table everything is fine.
When i change isLocal=false, the choices are displayed but not filtered.

Any idea?

Tobias

Re: PrimaryKey generation takes a lot of time

2014-05-07 Thread Tobias Janz
Hi all,

First i've tryed to set the size of primaryKeys fetched per statement in
_FrontBasePlugin to 500. I've gained abound 5%.
Next i've tryed to use ERXJDBCAdopter with batchsize 1000, but got no
benefit. Then I tryed connectionpooling, but ended with a lot of
exceptions, because the initialisation of Connections got broken. I
switched to ObjectStoreCoordinator and the performance got worse.

Multithreading did also slow down the application (With 2 Threads i got a
better performance by about 3-5%, but with more threads the performance
slows down by 5% with 10 Threads and 15% with 20 Threads).

My solution:
1. Return the hole multithreading, ObjectStoreCoordinator.
2. Configure Testinstance on Productionsystem only to import the data.
Database near Applikation got me to speed up. the 5 hours import is done in
5min.

Its not the best for me, but with the latency and slow connection issues
it's the best i can get.

Thanks for all your hints.

regards
Tobias

Re: PrimaryKey generation takes a lot of time

2014-05-06 Thread Tobias Janz
I forgott to replay to the list.

the database is close to the server. I did not find the way to copy the
Database from Mac OS Frontbase to CentOS Frontbase or the other way. I
tryed to recover me lokal Database with a Backup created with
CentOS-Frontbase, but it fails.

So I think the best way for me will be the WRITE ALL export.

I will take a look at this.

Thanks

PrimaryKey generation takes a lot of time

2014-05-05 Thread Tobias Janz
Hi all,

i need to import a csv-file with about 58.000 Lines und 60 Columns. I have
8 Entitys where the values will be stored. The conversion of a line to
entitys takes almost no time. But the full prozess, from conversion until
saveChanges is done, takes several hours (5-6h). After profiling it points
me to the generating of primary keys. This part uses half of the time.

I need to do the import several times.
Do you see a way to improve the speed?
I'm using WebObject 5.4.3 (with Wonder). My Development is on Mac. Database
is a Frontbase in the cloud on centOS.

Re: WOWODC 14 presentations and tickets

2014-02-12 Thread Tobias Janz
Hi there,

i'm realy sorry not coming to WOWODC. It would be a great thing for me
coming there. I started developing applications with WO in 2007. I switched
to another company and there we don't use WO, but
 I still use it for private projects. I love the easyness of WO, especially
with Project Wonder.

But i have do buy the ticket on my own cost and have to fly from Germany
and that is to much.

I wish you a good conference.

Re: Triggering AjaxObserveField through javascript

2013-05-07 Thread Tobias Janz
Hi Taylor,

i was wrong, sorry. the problem with the "myAjaxIDUpdate()" is that it will
do a "get" not a "post".

2 other solutions:

1. Add an AjaxObserveField to the List, which is updating all. At the AOF
set fullSubmit=true. Add an onChange to the List, where you call your
JavaScript to set the values.
Something like this:
ListForAll: 


2. And this is what I would do: Add an AjaxObserveField like above, but
with an action then you can set the value in your JavaCode. Example:
ListForAll: 


public WOActionResults setValuesFromListForAll() {
setList1Selection("SelectForAll");
setList2Selection("SelectForAll");
return null;
}

Hope this helps.

Tobias

Re: first attempt at many to many

2013-04-15 Thread Tobias Janz
hi,

its just like David said.
What extra information is that boolean?
If a Releationship between User and Project exists --> isToReceiveEmail =
true
If not --> isToReceiveEmail = false

Will you set "isToReceiveEmail" to false or remove the relationship.
If the Releationsship is only for the Email-Information, i would recommand
to not created redundant information and skip the boolean.

Re: [Excel] - Maximum column with EGSimpleTableCreator

2013-04-03 Thread Tobias Janz
Hi,

looks like nobody has used the ExcelGenerator-Framework with more than 255
Columns or a bit abstract with the xlsx-Format.
Maybe you could write an extension?
Also the version of the poi-jar is out of date, 3.9 is the latest stable
version (3.6 is 3 years old).
Looks like the SS Usermodel is a good idea.

Tobias

Re: Statement running too long

2013-03-26 Thread Tobias Janz
Hi,

the property is
er.extensions.ERXAdaptorChannelDelegate.trace.milliSeconds.error, default
5000 --> 5s

May take a look at the javadoc of ERXAdaptorChannelDelegate.

regards
Tobias
