problem running tutorial de.vogella.e4.todo

[Stefano]

Hello Lars,

first of all thanks for creating these wonderful tutorials for
eclipse. I have already gone through several ones with great benefit.

I have encountered a problem with running de.vogella.e4.todo.
Specifically, at section 10.6, when running the product, I am getting
this exception

java.lang.NullPointerException

Previously, at section 10.4 (Maintain Extension points) I was also
confused by the instruction:

"Every e4 application must define a base model. This is done via a
property of the product. Maintain the properties "applicationXMI" with
the value "de.vogella.e4.todo/Application.e4xmi This points to the
initial model which we will create soon. The resulting plugin.xml
should look like the following."

Since I could not find a way to create this property by means of the
wizards/editors, etc.,I edited directly the plugin.xml file (the
instruction of the tutorial seemed to suggest that...).
Am I missing something?

Thanks in advance.
Stefano

PS: here is the version I am using:

Eclipse SDK
Version: 4.1.0
Build id: I20110620-1631

Hi Stefano,

thanks for the feedback. This part of the tutorial has not yet been updated to Eclipse 4.1. I hope to do this within the next month.

Best regards, Lars
