Netbeans IDE 6.0 Database Application: question?

Thread view:

Dear Developers,

I'm busy developing a database application with Netbeans IDE 6.0 and
Mysql to automate the data management of my Dongo.org project. I have
a question as described below.

I've created two projects using "New Project/Java/Java Desktop
Application/Database Application" for two different tables in my Mysql
database. Since my goal is to have the management screens for the
different tables in a tabbed application I enclosed the GUI elements
of the first project in a panel and then in a tabbed panel.
Furthermore I enclosed the GUI elements of the second project in a
panel and copied and pasted this panel into the tabbed panel as a
second tab. Since with the copy and paste the binding properties of
the second mastertable were lost I reapplied those settings. Also I
added code for and modified the buttons actions in the second tab
since they referred to the first tab.

The problem I'm having is that for the new button on the second tab it
appears not all needed code is executed since visually no new line is
added to the mastertable. When debugging the original second project
it appears more code is executed than for the second tab (this is code
getting attributes of the new instance ...). Nevertheless I have no
idea how this code is triggered or called from. Anybody knows how to
solve this problem? Which mechanism is not working for my second tab?
Maybe it has something to do with the beans binding?

Thanks and best regards :-), BoBi

Please do NOT multi-post.

Cross-posted to re-unify the threads, bearing in mind that mostly the same
people read all three groups.

This seems like it should be done in a single project, since the tables are
apparently meant to work together somehow.

We, too, have no idea, and we're at a disadvantage because we have not the
benefit of seeing the source code, as you have.

I have no idea what you mean by that.

How about you post a complete example that evinces the problem you're trying
to solve? Without that it's unlikely one could be of assistance.

And don't multi-post any more.

If you would read the "comp.lang.java.{help,programmer} - what they're for
(mini-FAQ 2006-03-31)" post from David Alex Lamb in clj.help and ...programmer
appearing here every five days, and the links to which it leads, you'd understand.

Cross-posting, while not very useful when the readership between groups is
mostly the same and doing little to encourage folks to respond, is less sinful.

Hi,

Yes, sorry for not including the code. It was rather a lot all
generated by netbeans.

Now, because of different reasons I decided not to continue with the
data bindings provided in the netbeans ide nor the java desktop
database application like it is generated by the netbeans ide. Those
reasons being:
1. Something that should have worked simply did not work.
2. I was not too happy with the provided functionality anyway. Too
much clicks needed to perform the crud operations.
3. The whole construct is to complex, very hard to understand and
maintain and probably new versions will give an unneeded maintenance
problem.
So I will not use the data binding and conceive a solution using
directly the more basic Java components like the Jtable (without
databinding and writing my own tablemodel, ...).

Thanks :c), BoBi

I have to echo Lew's sentiments. We don't have nearly enough
information to determine what the issue is. Based on what you've
provided so far, I'd say that the second tab needs an action listener to
receive events and execute code, but that's really just a guess.

If you provide an example, please shorten it down a lot. I don't think
anyone is going to wade through an entire Swing + DB project to find an
error for you. Make a new project with a very simple tabbed pane that
exhibits the same behavior. You should be able to make something like
this in 50 lines of code or so, or less.
