Hi,

My application has 2 windows at the moment. at startup the login window is visible, the registration window not. on the login window is a link which calls a command. this is the handler to close the login window and open the registration window:

public class ShowPart {
	
	@Execute
	public void execute(final MApplication application, final EModelService ms, final EPartService partService,
			@Named("windowId") final String windowId) {

		// find the window to show
		MUIElement e = ms.find(windowId, application);
		e.setVisible(true);
		e.setOnTop(true);
		e.setToBeRendered(true);
		ms.bringToTop(e);
		
		// hide the others
		for (MWindow window : application.getChildren()) {
			if (!windowId.equals(window.getElementId())) {
				window.setVisible(false);
				window.setOnTop(false);
				window.setToBeRendered(false);
			}
		}
		
	}
}

This successfully closes the login window but it doesn't open my registration window.

What am i doing wrong?

thank you for your help,
mike

Does a Shell get created? Does its open() method get called? Or the setVisible(boolean) method (with a 'true' parameter)?

Why are you creating Workbench-Windows and not simply open a
TitleAreaDialog, Dialog, Shell?

BTW naturally opening/closing MWindows should work but I think you can
get around using native SWT/JFace-Code.

Did you have a look in my tutorial? I've successfully opened there
windows programmatically but things might have changed since 4.0.

Hi,

I finally found the problem:

When one defines a not visible window in the Application.e4xmi, the "To Be Rendered" checkbox must not be checked!
As soon as i unchecked it my command handler did his job.

I still don't know why it behaves like that. maybe one of you guys knows the answer?

thanks for your help and for eclipse 4/e4! I love using it!
