how to change exception message for date fields?

[pjydc]

hi, i have a date field that requires MM/dd/yyyy input.
however, if a user types "xyz", the form is re-displayed
with an error message as follows:

Failed to convert property value of type [java.lang.String] to required type [java.util.Date] for property 'startDate'; nested exception is java.lang.IllegalArgumentException: Could not parse date: Unparseable date: "xyz"

Suppose, we dont use any validator (client or server-side), how
can i change the above to let a user see a friendly message?

I would like to say that server side validator (specified through
<property name="validator"><ref bean="beanValidator"/></property>)
is not working, because a validator is called after
data binding is finished.

correct me if i am wrong.

thanks for your input!

p.s. i am using spring 1.1.5 and Commons validator 1.1.4

Hi Pete,

have you already registered a customEditor in your Controllers initBinder() method?

[pjydc]

yes, i registered a customEditor for date and it is able to
take input like MM/dd/yyyy. but it throws that horrible
message to users in chase a user enterd something like
MM/dd/20005 (5 digits). i am trying to make it robust and
user friendly.

thanks, pete

does anybody there have knowledge for handling this?

I'm having the same issue.

I'm actually attempting to code a solution now. I think I might try and replace the first FieldError in the List of errors with the error I want it to have. I'll post here if I come up with a solution.

In my view I use, ${status.errorMessage} to display the error message. It grabs the first error and displays it. The problem we're having is that the Spring-error message is the first on in the list, so it is displayed.

I tried to modify the list. (remove the first error, or add my own to the first position) But it looks like I can't modify the list directly. I keep getting errors like this:

java.lang.UnsupportedOperationException
java.util.Collections$UnmodifiableList.add(Collect ions.java:1144)

We must be missing something. It can't be this difficult.

michael,

i made a similar attempt at the server side trying to
replace the error message, but i found the message is
not replaceable. sounds similar to you?

thanks, pete

[michael]

Yep. No luck.

I'm at a lose for this. I wouldn't think I'd have to write a lot of code to get this to work. Can any of the spring guys shed some light on a method to solve this?

[pjydc]

can any spring pro out there helping us out on this?

thanks, pete

Sorry for the delay...

I haven't got the time to fully read the thread, but I think you're looking for the default error messages? The DataBinder adds a couple of pre-defined keys if the field is required, or if a type mismatch occurred. Have a look at the following classes to see what those defaults are. The DefaultMessageCodesResolver tries a couple of codes before falling back to the default (which is what you're getting).

If you define one of the codes (mentioned in DefaultMessageCodesResolver) in your message bundle (registered as the MessageSource in your context) you should be fine.

Hope this helps,

regards,
Alef Arendsen
