Problem with Calendar, getting a type mismatch error

[gbadavidson]

I have need to enter a date on my application. and I have the following in my web page:

<rich:calendar datePattern="MM/dd/yyyy" enableManualInput="true"
      value="#{personBean.person.birthDate}" popup="true">
</rich:calendar>

The personBean.person.birthDate field is defined as a java.sql.Date.  When I try to submit I get the following error:

java.lang.IllegalArgumentException: argument type mismatch

Thanks for your help

This is one of those "Nevermind" issues. I was using java.sql.date instead of java.util.date. When I switched to java.util.date the problem was fixed.

I do have a question, when would java.sql.date be approriate for use instead of java.util.date?

Thanks

Hi Glenn,

You can attach converter to calendar that will handle any type (including java.sql.Date) as to any input control.
