Component/s: Data Transformation
Labels:
None

Steps to Reproduce:

Hide

1. Brand new installation of JBoss Developer Studio + Fuse Tooling 11 on Mac
2. Create a Camel project
3. Add a Data Transformation component from the Palette
4. In the wizard - choose source type XML, target type Other
5. In Source Type, choose an XML Schema instance document
6. in Target Type, click the ellipsis to choose a Target Class
7. Either a NullPointerException is shown when trying to list the classes, or the list is empty.

Cannot then proceed with wizard, as this is a required step.
