IllegalArgumentException: Cannot convert value of type [java.lang.String] to required

[Vyas Sanzgiri]

I have a Date data type in form and when I try to input this
dateChanged is of data type Date which resides in input.processParameters.dateChanged. How do I fix this? I read something about initBinder but not sure.

Spring throws the following error:

Field error in object 'input' on field 'processParameters[2].dateChanged': rejected value [2009-09-21]; codes [typeMismatch.input.processParameters[2].dateChanged,typeMismatch.input.processParameters.dateChanged,typeMismatch.processParameters[2].dateChanged,typeMismatch.processParameters.dateChanged,typeMismatch.dateChanged,typeMismatch.java.util.Date,typeMismatch]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [input.processParameters[2].dateChanged,processParameters[2].dateChanged]; arguments []; default message [processParameters[2].dateChanged]]; default message [Failed to convert property value of type [java.lang.String] to required type [java.util.Date] for property 'processParameters[2].dateChanged'; nested exception is java.lang.IllegalArgumentException: Cannot convert value of type [java.lang.String] to required type [java.util.Date] for property 'dateChanged': no matching editors or conversion strategy found]

If I use the following intiBinder:

	protected void initBinder(HttpServletRequest request, ServletRequestDataBinder binder) {
		SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
		dateFormat.setLenient(true);
		binder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, true));
	}

I get the following error:

What are the versions of JRE and Spring you're using?

[Vyas Sanzgiri]

JRE 1.5

Spring 2.5.6

How does that matter??

It *could* matter, because they are software they have bugs. You're using Sun JRE or OpenJDK JRE?

Anyway, from the error log why there are 2 dates: 2009-09-21 and 2009-08-20?
And please post your command class code.

[Vyas Sanzgiri]

Sun JRE.

There are 2 dates cause processParameters is a ArrayList inside Input class and processParameters contains a dateChanged field

[Hong Anderson]

Please post the command class source code.

Change this:

protected void initBinder(HttpServletRequest request, ServletRequestDataBinder binder) {  
         SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");  
         dateFormat.setLenient(true);  
         binder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, true));  
}

To this:

protected void initBinder(HttpServletRequest request, ServletRequestDataBinder binder) {  
         super.initBinder(request, binder);

         SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");  
         dateFormat.setLenient(true);  
         binder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, true));  
}

Does not work same error :

Field [2009-08-20] isn't an enum value java.lang.NoSuchFieldException: 2009-08-20
