Hello,
I want to show a Dialog from a Handler, but after I get a org.eclipse.e4.core.di.InjectionException: java.lang.NullPointerException
This is my Handler:
public class PreferenceHandler {
@Execute
public void execute(IEclipseContext context, IWorkbench workbench) {
PreferenceDialog dialog = ContextInjectionFactory.make(PreferenceDialog.class, context);
dialog.open();
}
}
and this is my Dialog:
public class PreferenceDialog extends TitleAreaDialog {
@Inject
public PreferenceDialog(
@Named(IServiceConstants.ACTIVE_SHELL) Shell parentShell) {
super(parentShell);
}
@Override
protected Control createDialogArea(Composite parent) {
Composite area = (Composite) super.createDialogArea(parent);
getShell().setText("Connection informations");
return area;
}
}
My Enviroment:
windows 7
jdk 1.6.0_27 (32 bit)
Eclipse SDK 4.1.0

Hello Tom
The problem got solved by adding plugins manually to exported product.
we are showing progress dialogs in non-ui code in classes.
for some code, i made below change:
I created a Shell shell
Showed a progress dialo
closed shell
code:
// PlatformUI.getWorkbench().getActiveWorkbenchWindow(); // old code
// Shell shell = win != null ? win.getShell() : null; / old code
Shell shell = new Shell();
if (showProgress) {
new ProgressMonitorDialog(shell).run(true, true, op);
} else {
op.run(null);
}
shell.close();
I do not want to create and close shell.
I do not feel that this may be good idea, to do it at every place in code.
So can we get E4 display/shell in non-UI code or just use Display.asyn....
Can we get the shell of running E4 plugin at run-time using any inject logic.
I searched google but no luck in that so far.
Please help
regards
Parvez Ahmad Hakim
