rich:calendar doesnt accept java.util.Calendar in Seam 2.0.1 GA

[shiv]

Hi,

I have been trying to use java.util.Calendar with rich:calendar but have had no success. JIRA issue RF-933 says this has been fixed in 3.1.3 and 3.2.0. I am using Seam 2.0.1 GA. Any help would be appreciated.

registration.xhtml:

<rich:calendar id="dob" value="#{person.dob}" popup="true" required="true" />

Person.java:

import java.util.Calendar;


@Entity

@Name("person")

@Table(schema="public")

public class Person extends Party {


     public Person() {}

     

     @Column(nullable=false)     

     private Calendar dob;

     

     public Calendar getDob() {

          return dob;

     }


     public void setDob(Calendar dob) {

          this.dob = dob;

     }


     ......

     ......

     ......

}

Error Message:

/registration.xhtml @40,107 value="#{person.dob}": java.lang.IllegalArgumentException: argument type mismatch

Shiv

Ask on RichFaces forum.

[svadu]

You want to use java.util.Date

[shiv]

No I dont. The design of the system was based on the claims of what Seam can do, How it works and Whats been fixed. To change the design just because something doesnt work as expected is definitely not a solution. Have got no answer on the RichFaces forum too.

Please control you tone, otherwise you will have a short stay here.

My profound apologies if my reply sounded offensive.

Its the R and D work we had to do so many times to figure out / solve something, which is hitting our productivity. In this case we already spent 2 days with the rich:calendar thingy.

Again, pls accept my apologies.

Shiv,

Have you tried using a java.util.Date just to see if things work?  Siarhei was simply trying to suggest an alternative.  if Dates worked instead of Calendars, then that means the RF bug likely hasn't been fixed yet.  However, if Dates also didn't work, then something else is occurring.

As a last resort you can always use a Converter or add another getter/setter to the Person object to front the Calendar object with a Date. 

Good luck,

Keith

Hi Keith,

Thanks for the response. I did try using java.util.Date and it worked. Its a problem only when using java.util.Calendar.

Using the converter is a good tip. Will try that out. Thanks!

Hi, Shiv,

You can use this code:

<rich:calendar id="dob" value="#{person.dob.time}" popup="true" required="true" />

Good luck,

Yes, I always use it with Date.

Hint to the RF developers: it really should take an argument of type Long.  java.util.Date is a strange class that probably shouldn't be used anymore.

Doh!
Never thought of that solution!
I would give you star if I could.

2 and a half years on and still the same problem using Seam 2.2

But your advice of using calendar.time instead of calendar solves the issue well!
