Hi,

We are facing this resetting of date variables of a POF enabled object to System Date any time when object is looked up from cache.

Here is the driver program that I use. Please help!!!

package com;

import java.util.ArrayList;
import java.util.Date;

import com.tangosol.net.CacheFactory;
import com.tangosol.net.NamedCache;

public class POFDates {
public static void main(String[] args) {
// create cache
try {
NamedCache testEntryCache = CacheFactory.getCache("TESTCACHE");
Date myDate = new Date(System.currentTimeMillis());
Date myDate1 = new Date(System.currentTimeMillis()+24*3600*1000);
Date date1 =new Date(System.currentTimeMillis()+2*24*3600*1000);
ArrayList potentialDates = new ArrayList();
potentialDates.add(date1);
Other other = new Other("FirstOther",myDate);
Dates dates = new Dates("FirstMe",myDate,potentialDates,other);
System.out.println("****Dates initialy set in cache***"+dates);
testEntryCache.put("dates",dates);
Dates retrivedDates = null;
retrivedDates = (Dates) testEntryCache.get("dates");
System.out.println("-----Dates retrieved first Time from Cache------"
+ retrivedDates);
for (int i = 0; i < 3; i++) {
Thread.sleep(3000);
retrivedDates = (Dates) testEntryCache.get("dates");
System.out.println("####Dates retrieved "+i+"th Time from Cache"
+ retrivedDates);
}

} catch (Exception e) {
e.printStackTrace();
}
}
}

Output of the program is


****Dates initialy set in cache*** Dates.myDate = Wed Mar 31 22:40:58 CDT 2010<<< Dates.potentialDates = [Fri Apr 02 22:40:58 CDT 2010]<<< Dates.Other = Others' myDate:Wed Mar 31 22:40:58 CDT 2010<<<
