billy commented on WW-4703:
---------------------------

I know this information. I doesn't get what you mean "For now you can define a setter like this [2] and container field in your action" <-- how to do this?

Can you tell some practical example?

I have mentioned that it worked at 2.3.24.3

> 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:
> {noformat}
> 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)
> {noformat}
> 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.
