Description

When we use getText method in a ModelDriven's bean. We got NullPointerException in ActionSupport. We found the variable "container" is null when the bean is got from ModelDriven.getModel()

Following is the exception stack:

java.lang.NullPointerException
	at com.opensymphony.xwork2.ActionSupport.getLocale(ActionSupport.java:68)
	at com.opensymphony.xwork2.TextProviderSupport.getLocale(TextProviderSupport.java:329)
	at com.opensymphony.xwork2.TextProviderSupport.getText(TextProviderSupport.java:204)
	at com.opensymphony.xwork2.TextProviderSupport.getText(TextProviderSupport.java:119)
	at com.opensymphony.xwork2.ActionSupport.getText(ActionSupport.java:86)

Note: we are upgrading the project from 2.3.24.3 to 2.5.5. In version 2.3.24.3 doesn't have this issue.
