Problem with DataBindingContext into UIDialog

[Angelo zerr]

Hi,

I would like open the AbstractXPathExpressionDemo into dialog into AbstractDemo.
So to do that you can do :

UIDialog dialog = fact.newDialog(window, new UIDialog.DialogUIInfo(fact.newFillLayout(),buttons,UIDialog.DialogUIInfo.CLOSE_WINDOW_BUTTON));
dialog.setText("XPath Editor");
               
AbstractXPathExpressionDemo xpathUIContent = new AbstractXPathExpressionDemo() {};
xpathUIContent.createUI(dialog);

The problem is that I'm using Databinding and I have
Exception in thread "main" org.eclipse.core.runtime.AssertionFailedException: null argument:Validation realm cannot be null

when I try to open the dialog (it works perfectly with JFaceXPathExpressionDemo, not with dialog) .

It's normal, because when I check Realm.getDefault() and is null.

have you an idea to manage DataBindingContext into UIDialog?

Thank for your help.

Hi,

Need to take a look why this Realm returns null is the code in SVN?

Take a look at the commit. The problem was that the application code in
JFaceDemo looked like this:

-----8<-----
Realm.runWithDefault(SWTObservables.getRealm(display), new Runnable() {
public void run() {
try {
UIApplicationWindow window = createUI(uiMethod);

} catch (Throwable t) {
t.printStackTrace();
}
}
});

while( ! window.isDisposed() ) {
if( ! display.readAndDispatch() ) {
display.sleep();
}
}
-----8<-----

and this means that all is fine while we are setting up the UI but at
the moment we create UI-Elements after the intial createUI-call
(which you did in opening the dialog) the runnable is over and no
default-realm is set anymore hence the exception.

We are going to run into the same problems with Swing and QT - I need to
take a look tonight how we can solve this issue in a better way.
I think for QT the same can be done than for SWT but Swing has no event
loop I can spin itself so it might be a problem too.

Hi Angelo,

You could fix this until we have a better solution by setting a simply
setting a default realm:

public void run(final String uiMethod) {
SwingRealm.createDefault();
Realm.runWithDefault(SwingObservables.getRealm(), new Runnable() {
public void run() {
try {

createUI(uiMethod);
} catch (Throwable t) {
t.printStackTrace();
}
}
});
}

Do you have time for an IRC-Session - I want to shutdown work and move
code to Eclipse.org. We are a bit short of time.
