#4 NullPointerException when exporting metrics

[Anonymous]

Just installed the eclipse plugin from

http://www.stateofflow.com/UpdateSite

When I export the metrics for my project, the following
error occurs:

java.lang.NullPointerException

I experience the same problem during build. The problem disappears if I exclude enumerations from the metrics calculation. Is there a problem calculating metrics for enumerations?

The AST of an enumaration does not contain an TypeDeclaration.
For the enumeration
public enum Test {
HELLO,
WORLD;
}
the AST would look as follows:
-CompilationUnit
L-- EnumDeclaration
|-- Modifier
|-- SimpleName
|-- EnumConstantDeclaration
| L-- SimpleName
L-- EnumConstantDeclaration
L-- SimpleName

redbarron_two, you are correct. I'll try to fix this soon.
