Freemarker: null value displayed

I have this code:

<input type="text" name="zipCode" maxlength="5" value="${zipCode!}">

When zipCode = null (I use Java), the input field displayes null. Why?

Thanks!

In Freemarker doc:

If the default value is omitted, then it will be empty string

So, in your case Freemarker consider zipCode with type String, and this happens:

java.lang.String

public static String valueOf(Object obj) {
  return (obj == null) ? "null" : obj.toString();
}

and you get null as result.

If you want empty string instead null just use !""

<input type="text" name="zipCode" maxlength="5" value="${zipCode!""}">
