Not really.... what I'm trying to do is build an action that does not
depend upon the S2/xwork APIs, but can still work with them.
Specifically, I'd rather have:
public class MyAction
extends (nothing)
implements (Nothing)
{
public void addFieldError(String field, String message) { ... };
}
rather than this:
public class MyAction
extends ActionSupport
and/or
implements ValidationAware
{
// addError declared in ValidationAware
public void addFieldError(String field, String message) { ... };
}
I believe the ValidationInterceptor has code that looks something like this:
if(action instanceof ValidationAware)
{
foreach field {
validate field
if(error)
action.addFieldError(fieldName, errorMessage);
}
}
I was wondering if there was any interest in an alternative
implementation that did something more like this:
if(declaresValidationMethods(action.getClass())
{
foreach field {
validate field
if(error)
action.addFieldError(fieldName, errorMessage);
}
}
I could certainly implement this myself, but I'm wondering if there is
wider interest in such an interceptor.
Thanks,
