I think it is better for my app to create a further InteractionDialog.
When I do so I have to manage the back command on toolbar.
The user experience is to start from the main form, then call a second form
and there the first dialog is displayed.
This is the code portion at the beginning of the method that shows the
second dialog from the first dialog:
Toolbar toolbar=form.getToolbar();
InteractionDialog dialog=new InteractionDialog();
Command oldBackCommand=form.getBackCommand(); //no method
toolbar.getBackCommand()
Command backCommand=new Command("Back") {
@Override
public void actionPerformed(ActionEvent evt) {
toolbar.setBackCommand(oldBackCommand);
form.setBackCommand(oldBackCommand);
dialog.dispose();
}
};
form.setBackCommand(backCommand);
//or
//form.setBackCommand(null); same behaviour
toolbar.setBackCommand(backCommand);
....
....
What I get is that when the second dialog is displayed (full screen) and I
would click the back button, it is the same I would click the back button
on the form, so the previous form is shown back while I want to stay on the
current form with the first dialog displayed.
I just wanted to dispose the second dialog to go back to the previous
dialog, not the previous form.
What's wrong?
