Hartmut,
I do it at the end of an action's perform() method using the "construction"
given in my previous reply!
What I describe is only valid if your controller checks for errors itself.
In case you let Struts handle the validation automatically, I advice you to
look at the Struts source code.
The following code snippet is from the Action.java class:
/**
* The request attributes key under which your action should store an
* <code>org.apache.struts.action.ActionErrors</code> object, if you
* are using the corresponding custom tag library elements.
*/
public static final String ERROR_KEY = "org.apache.struts.action.ERROR";
Concluding: the errors are stored in the request (session?) attribute
"org.apache.struts.action.ERROR".
Regards,
Guus
