Greetings.
I want to build subversive extension which shows a simply MySimpleDialog after I press "OK" button on the commit dialog.
Then I can do some actions on MySimpleDialog and press button "go ahead" on it. 
After "go ahead" button pressed -> the commit process begins, 
all the windows closes and some text from MySimpleDialog adds to comment text.
Now I wrote some plugin which extends org.polarion.team.svn.ui.commit,
So, MyCommitActionFactory extends ICommitActionFactoty where "open" method returns MyComitDialog:
MyComitDialog extends DefaulDialog.
In MyComitDialog i overrided "buttonPressed" method to show MySimpleDialog (MySimpleDialog is inner-class in MyComitDialog).
Then I added a simple listener to  "go ahead" button on MySimpleDialog which do the same that "buttonPressed" in DefaulDialog does.
Here is the code:
...
public class MyCommitActionFactory implements ICommitActionFactory {
	public ICommitDialog getCommitDialog(final Shell shell, Collection allFilesToCommit, final ICommentDialogPanel commentPanel) {
		return new ICommitDialog() {
			public String getMessage() {
				return "testCommitMessage" + commentPanel.getMessage();
			}
			
			public int open() {
				dialog = new MyCommitDialog(new Shell(shell), commentPanel);
				return dialog.open();
			}
		};
	}
...
}
...
public class MyCommitDialog extends DefaultDialog {
...
	protected void buttonPressed(int buttonId) {
		if (IDialogConstants.OK_ID == buttonId) {
			showMySimpleDialog(buttonId);
		} else {
			super.buttonPressed(buttonId);
		}
	}
...
	public void preCommitAction() {
		JOptionPane.showMessageDialog(...);
		//XXX:dont works
		super.buttonPressed(IDialogConstants.OK_ID);
	}
...
	protected class MySimpleDialog {
	...
	public void addListener() {
		buttonGoAhead.addActionListener(new ActionListener() {
			@Override
			public void actionPerformed(ActionEvent e) {
				preCommitAction();
			}
		});
		}
	...
	}
...
}
So, when I press GoAhead Button, the preCommitAction() invokes. It shows JOptionPane, but the Button in DefaultDialog doesnn't presses!
My questions are:
1. How can I press the button "OK" on DefaultDialog from MySimpeDialog (or how to do commit action)?
2. How can I add some text from MySimpleDialog to comment text?
Thank you!
With best regards, Andrey Pavlenko.
