WizardManager.bean.action and actions?

[esource]

In actions.jsp, there is a declaration that displays the list of actions to apply to a node:

<h:selectOneMenu value="#{WizardManager.bean.action}" id="action" onchange="javascript:itemSelected(this);">
<f:selectItems value="#{WizardManager.bean.actions}" /'>
</h:selectOneMenu>

I looked in org.alfresco.web.bean.wizard.WizardManager.java but am not sure what is being referred to in value="#{WizardManager.bean.action}" and value="#{WizardManager.bean.actions}".  What is being referred to in bean.action and bean.actions?  I didn't find any declarations like that in WizardManager.

It seems to refer to BaseActionWizard action and actions.
