Logic for startDate not < 2 weeks from endDate, not working

I had written the logic for startDate must not be < 2 weeks from endDate,but it is not executing.so where should I write the logic in a sample Report i.e IssueCreationReport ?

        if (projectId == null)
            action.addError("projectid", action.getText("report.issuecreation.projectid.invalid"));
        
        // The End Date after 2 weeks
        
        if (diffDays > 14)
            action.addError("startDate", action.getText("Days difference must be with in 2 weeks"));
               
        // The end date must be after the start date
        
        if (startDate != null && endDate != null && endDate.before(startDate))
        {
            action.addError("endDate", action.getText("report.issuecreation.before.startdate"));
        }
    }
}

This is the file and the logic I have written is

        Calendar startDate = Calendar.getInstance();
        Calendar endDate = Calendar.getInstance();
        long millis1 = startDate.getTimeInMillis();
        long millis2 = endDate.getTimeInMillis();
        long diff = millis2 - millis1;
        long diffDays = diff / (24 * 60 * 60 * 1000);
 
        // Split the specified time period by the interval value
        while (diffDays < 14).

Is this correct? If not Please update the correct one.

I'm not clear where you are trying to do the validation or why? (Franky, I'm not going to spend any time going through your code to try to guess what you're trying to do). The question is are you trying to validate the user has selected valid dates (in which case, do it in the validate function) or for processing the reported information (in which case, it goes in the body of the report)

This widget could not be displayed.

I was able to accomplish something similar. Here's an example:

Calendar start = Calendar.getInstance();

Calendar end = Calendar.getInstance();

Now if, you wanted to iterate through them, you would do something like:

while(start.before(end)) {

... do some stuff

//decrement the calendar

start.add(Calendar.DATE, -1);

}

The before function is part of Calendar. There is also an "after" function.
