Re: Do Intersection TemporalExpressions work?

Technically, you are correct - the next date being returned is wrong,but partly because the class is being used incorrectly. If you provide astarting calendar to the expression's first method, and then pass thereturned date to the next method, the dates returned will be correct.

The temporal expressions should provide an iterator instead of thehaving the first and next methods - that would eliminate the problem youencountered.

Hello,

I seem to be having problems getting TemporalExpressions to work. They seem to 
work fine for some expressions. But not for INTERSECTION types. I am using the 
TE definition from the sample data in ServiceDemoData.xml for INDEPENDENCE_DAY, 
specifically this:

     <TemporalExpression tempExprId="INDEPENDENCE_DAY" 
tempExprTypeId="INTERSECTION"/>
     <TemporalExpressionAssoc fromTempExprId="INDEPENDENCE_DAY" 
toTempExprId="MONTH_RANGE_07"/>
     <TemporalExpressionAssoc fromTempExprId="INDEPENDENCE_DAY" 
toTempExprId="DAYOFMONTH_04"/>

And I'm using the following code to iterate over a number of days to see when 
the next Independence Day will occur:

com.ibm.icu.util.Calendar cal = new com.ibm.icu.util.GregorianCalendar();
java.util.Date start = UtilDateTime.toDate("06/01/2011 00:00:00");
cal.setTime(start);

GenericValue temporalExpression = delegator.findOne("TemporalExpression", 
UtilMisc.toMap("tempExprId", "INDEPENDENCE_DAY"), true);
TemporalExpression selectionDeadline = 
TemporalExpressionWorker.makeTemporalExpression(delegator, temporalExpression);

for (int index = 0; index<  60; index++)
{
        Date nextDate = new Date(selectionDeadline.next(cal).getTimeInMillis());
        Debug.logInfo(String.format("%s ->  %s", new Date(cal.getTimeInMillis()), 
nextDate), "Groovy");

        cal.add(com.ibm.icu.util.Calendar.DATE, 1);
}

It doesn't do the right thing for the first 4 days of July. It says for 
7/1/2011 that the next occurrence is 7/4/2012. Here is the output:

I also tried the TE.first() method and it gave different results that were also 
wrong. I think it must be a bug. I haven't found a fix yet and I'm hesitant to 
change this code as I know at least the job scheduler relies on 
TemporalExpressions.

Thanks for any guidance.
