In Section 2.4. Creating a ESB File we mention:

At first you should open any project. Select File → New → Other... in the main menu bar or context menu for selected project and then ESB → ESB File in the New dialog:

This is wrong, since esb editor will properly work only on ESB Files in project having ESB facet. See discussion in JBIDE-6863

Figure 2.20. New ESB Action wizard

In the screenshot 'As annotated POJO' is selected and at the same time superclass is defined. This is wrong screenshot. This cannot happen in New ESB Action wizard (try (un)checking radiobuttons above)
Starting ESB 4.9 An action class could be an annotated POJO class. Annotation details http://community.jboss.org/wiki/JBossESBActionAnnotations.

We should fix the screenhost to be consistent with text and/or also mention the other (POJO) option creating an action class.
