Hi,

  Thanks for the immediate response. As suggested by you I have ignored the
type selector wizard. But while run the project using Run Configuration >
LibreOffice Application I am getting the following error message:

"Unhandled event loop exception" in the plugin: org.eclipse.ui

The full stack trace is


java.lang.NullPointerException
