can't get ExceptionDates

[Anonymous]

Hello,

I'm currently getting to know the library and am stuck at a problem:
my iCalendar has some ExceptionDates when viewing the file itself, but when creating the object trhough the library, i can't get any of these ExceptionDates (vEvent.getExceptionDates() allways returns a empty list).

Am I doing this wrong, or is it a bug?

Thanks in advance!
Johannes

Johannes,

Can you show me the iCal file you are trying to parse?

Thanks,
Mike

Hey Mike,

thanks for the fast reply! I attached the file ;)

The EXDATE property values all end with a comma character, which isn't supposed to happen. This is preventing biweekly from parsing them.

As a work-around, you could retrieve the properties as raw properties, and then parse them manually:

:::java
ICalendar ical = ...
ExceptionDatesScribe scribe = new ExceptionDatesScribe();
List<RawProperty> rawProps = ical.getExperimentalProperties(scribe.getPropertyName());
List<ExceptionDates> exdates = new ArrayList<ExceptionDates>();
for (RawProperty rawProp : rawProps) {
  String value = rawProp.getValue();
  value = value.substring(0, value.length() - 1); //chop off ","

  ICalDataType dataType = rawProp.getDataType();
  if (dataType == null){
    dataType = scribe.getDefaultDataType();
  }
  Result<ExceptionDates> result = scribe.parseText(value, dataType, rawProp.getParameters());
  exdates.add(result.getProperty());
}

Thanks a lot Mike!

i thought that might be the problem, too :P

the class ExceptionDatesScribe is not available in the current version.. will this class be added in a future release?

[Michael Angstadt]

What version are you running?

[Michael Angstadt]

Oh, right. I forgot I changed the name of that class. Its old name is "ExceptionDatesMarshaller". FYI: I just released a new version today (version 0.3.3) if you want to use that. :)

thanks! I just included the latest version, but the rawProps list is allways empty... :S

[Michael Angstadt]

Oops, my mistake. In your case, the EXDATE properties exist within VEVENT components. So you have to iterate over all the properties in each VEVENT:

:::java
//parses the broken EXDATE properties and adds them back to the ICalendar object properly
ICalendar ical = Biweekly.parse(new File("testCal[1].ics")).first();
ExceptionDatesScribe scribe = new ExceptionDatesScribe();

for (VEvent event : ical.getEvents()) {
  List<RawProperty> rawProps = event.getExperimentalProperties(scribe.getPropertyName());
  for (RawProperty rawProp : rawProps) {
    String value = rawProp.getValue();
    value = value.substring(0, value.length() - 1); //chop off ","

    ICalDataType dataType = rawProp.getDataType();
    if (dataType == null) {
      dataType = scribe.getDefaultDataType();
    }
    Result<ExceptionDates> result = scribe.parseText(value, dataType, rawProp.getParameters());
    event.addExceptionDates(result.getProperty());
  }

  event.removeExperimentalProperty(scribe.getPropertyName());
}

awesome, it's working now =) thanks alot, mike!

[Michael Angstadt]

You're welcome!

I'm back once again for another question, mike!

Could it be that - due to this error in the file - the Location-Attribute won't get parsed?

I tried to retrieve it, but it allways returns an empty String...

Thanks in davance!
