All,
Some of you know that JFace and VE have been working together on a new
data binding framework for Eclipse. In many cases, this will let you
replace pages of SWT event handlers with code like:
dataBinding.bind(textWidget, new Property(personBean, "name"), null);
There are two talks proposed about this new exciting framework at
EclipseCon:
http://canuck.gda.itesm.mx/eclipsezilla/show_bug.cgi?id=271
by myself, and
http://canuck.gda.itesm.mx/eclipsezilla/show_bug.cgi?id=89
by Boris Bokowski, a member of the JFace team
If you want to hear about this at EclipseCon, please vote today for one
or more of these submissions!
Best regards,
Dave Orme

Officially, I don't think we've decided. Right now you can do it, but
we're talking about adding some dependencies on one of the new plugins
in 3.2, and I don't know how that discussion will turn out.
If you think it's important to keep backward compatibility with 3.1.1,
please file a bug report against Platform/UI with [DataBinding] in the
summary and we'll discuss it there.

No, the backward compatibility with 3.1.1 is not necessary in this case.
I just need to finish the project as soon as possible, and I can't wait
until February for stable release. I've just downloaded sources from
CVS and I'm going to try to use them in my app.

I've imported databinding packages from CVS. But when I try to start any
example (e.g. I try to execute "run as java bean" on TextBinding.java from
org.eclipse.jface.examples.databinding.javabean package) I get this:
Exception in thread "main" java.lang.NoClassDefFoundError: org.eclipse.ui.part.WorkbenchPart
at org.eclipse.ve.internal.java.vce.launcher.remotevm.RCPLaunch er.supportsLaunching(RCPLauncher.java:40)
at org.eclipse.ve.internal.java.vce.launcher.remotevm.JavaBeans Launcher.main(JavaBeansLauncher.java:71)
What's wrong?

I've copied the org.eclipse.jface.examples.databinding.javabean classes
into my project, in order to be able to play with them safely.
But they wouldn't work. I tried to debug, and found problem in
getGetMethod() method of JavaBeanUpdatable() class (look at the try
statement - it has local variable Method getMethod so it will never
return value.
I fixed this, and it runs but... still doesn't work. I mean: I have window
with labels and text boxes, but changing value in one box doesn't
change value in other box. Why?

It's not my code. It's the javabean example from CVS.
I can't run this example "as SWT App", 'cause it has no main() procedure
etc.
It is bean (nomen omen)... :)
Here is the ONLY part I've changed to run it:
private Method getGetMethod() {
if (getMethod != null)
return getMethod;
try {
String getMethodName = getMethodName(propertyName);
//Method getMethod = object.getClass().getMethod(getMethodName, null);
return getMethod = object.getClass().getMethod(getMethodName, null);
} catch (NoSuchMethodException e) {
}
return getMethod;
}
You can see the commented-out line and one added below.
That's all.
And now it runs, but... doesn't work...
I can drop it into bugzilla, but maybe you can answer me here?

I've imported databinding packages from CVS. But when I try to start any
example (e.g. I try to execute "run as java bean" on TextBinding.java from
org.eclipse.jface.examples.databinding.javabean package) I get this:
Exception in thread "main" java.lang.NoClassDefFoundError: org.eclipse.ui.part.WorkbenchPart
at org.eclipse.ve.internal.java.vce.launcher.remotevm.RCPLaunch er.supportsLaunching(RCPLauncher.java:40)
at org.eclipse.ve.internal.java.vce.launcher.remotevm.JavaBeans Launcher.main(JavaBeansLauncher.java:71)
What's wrong?

I've copied the org.eclipse.jface.examples.databinding.javabean classes
into my project, in order to be able to play with them safely.
But they wouldn't work. I tried to debug, and found problem in
getGetMethod() method of JavaBeanUpdatable() class (look at the try
statement - it has local variable Method getMethod so it will never
return value.
I fixed this, and it runs but... still doesn't work. I mean: I have window
with labels and text boxes, but changing value in one box doesn't
change value in other box. Why?
Best regards,

Try: "Run as SWT Application"

It's not my code. It's the javabean example from CVS.
I can't run this example "as SWT App", 'cause it has no main() procedure
etc.
It is bean (nomen omen)... :)
Here is the ONLY part I've changed to run it:
private Method getGetMethod() {
if (getMethod != null)
return getMethod;
try {
String getMethodName = getMethodName(propertyName);
//Method getMethod = object.getClass().getMethod(getMethodName, null);
return getMethod = object.getClass().getMethod(getMethodName, null);
} catch (NoSuchMethodException e) {
}
return getMethod;
}
You can see the commented-out line and one added below.
That's all.
And now it runs, but... doesn't work...
I can drop it into bugzilla, but maybe you can answer me here?
