Adam Crume updated WW-2255:
---------------------------
Attachment: ConversionErrorInterceptor2.java
It's not elegant, but this can be achieved by removing the old conversionError
interceptor and adding this modified one *after* the validation interceptor.
It works by overwriting any validation error messages a field has if it has a
conversion error.
I had to copy and modify the code in
org.apache.struts2.interceptor.StrutsConversionErrorInterceptor and
com.opensymphony.xwork2.interceptor.ConversionErrorInterceptor because the
logic couldn't be changed easily by subclassing.
> Field validators should be skipped if there is a conversion error

> If there is an error converting a field, the validators for that field should
> be skipped. For example, let's say I have an action with an "age" field
> declared as an Integer, and the field is required. If the user enters "one",
> the user will see two errors: one from the conversion process, and one from
> the required validator (since the field was never assigned).
> In general, a conversion error should short-circuit all validators for that
> field, since validators depend on the field being set, which never happens if
> there was a conversion error.
