[SWTBot-users] WidgetNotFoundException when running SWTBotDemo

[Hans S. <han...@ya...>]

When I run "net.sf.swtbot.demo.SWTBotDemo" I get this exception:

Exception in thread "main" net.sf.swtbot.widgets.WidgetNotFoundException: Could not find widget with text One

It seems that SWT Bot cannot access the button, although I don't see any reason why not. If I comment the statement "bot.button("One").click();" then the rest of the demo works.
