NPE Opening jsp with JDev 10.1.3

Question

I am trying tutorial Oracle Database Express Edition, 2 Day Plus Java Developer Guide. I instaled JDev clean and installed updates available. Everything was fine until I created jsp using the following directions.
1. In the Application Navigator, right-click the View project and choose New from
the shortcut menu.
2. In the New Gallery, from the Filter By: list, select All Technologies.
3. Expand the Web Tier node and select JavaServer Pages (JSP).
4. In the Items list, select JSP Page and click OK.
5. In the Create JSP dialog box, enter employees.jsp for the File Name and click
OK. The new page opens in the JSP/HTML Visual Editor and is ready for you to
start adding text and components to your web page.

Answer 1

Hi Tim,
Looks like a bug to me. Can you confirm the version and what steps you did to create the application workspace prior to step 1? Also did the exceptions appear once the editor was up or after you started doing something, e.g. typing.
