Eric Lentz created WW-4071:
------------------------------
Summary: ValidationAware add callable method, called from
DefaultWorkflowInterceptor
Key: WW-4071
URL: https://issues.apache.org/jira/browse/WW-4071
Project: Struts 2
Issue Type: New Feature
Components: Core Interceptors
Affects Versions: 2.3.14
Reporter: Eric Lentz
Priority: Minor
When a form error occurs, the action is unaware of this event. There are
situations whereby one should know that a form error has occurred. For example,
one may wish to populate the ActionStack with special handling variables or set
a flag denoting special logic that the JSP should handle. In short, it isn't
unreasonable for one to want to know that a form error occurred and be able to
respond to it with more than just a single JSP result attached to "input."
My suggestion would be within ValidationAware, add a method:
void actionError()
Within DefaultWorkflowInterceptor.doIntercept, there is already an if condition
of:
if (validationAwareAction.hasErrors()) {
at the end of processing that if block, just before, "return resultName;" call
validationAwareAction.actionError();
By the way, this line:
LOG.debug("Errors on action " + validationAwareAction + ", returning result
name 'input'");
should be:
LOG.debug("Errors on action " + validationAwareAction + ", returning result
name '" + inputResultName + "'");
