#167 Exception when ical file contains property: ACKNOWLEDGED

[abouda]

Trying to parse ics file with ACKNOWLEDGED property:

ACKNOWLEDGED:20130927T141516Z

http://tools.ietf.org/html/draft-daboo-valarm-extensions-04#section-8.1

Fails with Exception:

W/System.err(18269): net.fortuna.ical4j.data.ParserException: Error at line 40:Illegal property [ACKNOWLEDGED]
W/System.err(18269): at net.fortuna.ical4j.data.CalendarParserImpl.parse(CalendarParserImpl.java:148)
W/System.err(18269): at net.fortuna.ical4j.data.CalendarBuilder.build(CalendarBuilder.java:210)

what is the status of that bug ?

[Tobias Baum]

If anyone needs a workaround: Enabling relaxed parsing using
CompatibilityHints.setHintEnabled(CompatibilityHints.KEY_RELAXED_PARSING, true);
suppressed this problem for me.

Also note that the latest snapshot build of ical4j-extensions includes support for the ACKNOWLEDGED property, and it will be available in the next release:
