String to int - java.lang.NumberFormatException

[larry]

I have a Spring MVC SimpleFormController and a Validator which handle form submissions.

I'm getting this error:

Failed to convert property value of type [[Ljava.lang.String;] to required type [int] for property 'year'; nested exception is java.lang.NumberFormatException: For input string: "0,"

Doesn't Spring MVC support String to int conversion by default? At least according to documentation it should.

Your string has a comma in it ("0,"). If these is valid for the locale, and you need to support custom property editors, you need to use a wrapper class.

I did not even notice, or expect, the comma. It's not coming from my code. The values are coming from a select field and are pre-defined. They contain no commas.

<option value="2006" >
2006
</option>

Where could the comma be coming from?

Where could the comma be coming from?

Possibly two HTML fields with the same name.

Look at the HTML source as well.

You were right I had two fields called year in the HTML form. Thanks a lot. I would probably have spent a day looking for the answer.
