Hi.
Simple CRUD sample application, paramsPrepareParams, wildcard method
selection.
Cancel button in edit form, when reached for creating a new employee
bean, is not cancelling and redirecting to index, but actually
performing form action, which is "save". Conversely, cancel is working
properly if edit form is reached from "edit" link, instead of "create".
I guess it has to do with interceptors stacks and validation, but I
have no idea where the problem is.
Code for cancel button in employeeForm.jsp:
<s:submit value="%{getText('button.label.cancel')}"
name="redirectAction:index"/>
Working on issue: https://issues.apache.org/jira/browse/WW-3993
Thanks!
