Hi
I’m trying to evaluate the charts add-on in a simple prototype application using the Maven application archetype within IntelliJ IDEA 13 and have run into a problem trying to run the install goal. Although following the steps in the Book of Vaadin and building the widget set using the maven goal appears to be successful, attempts to compile and deploy fail with an annoyingly cryptic GWT internal error that doesn’t give me enough information to track the bug down. I’m sure I have done something wrong but despite cleaning and then rebuilding the project from scratch I can’t seem to escape from the error. If anyone is able to help I’d be very grateful!
Console output (install goal):
Information:Compilation completed with 20 errors and 0 warnings in 9 sec
Information:20 errors
Information:0 warnings

setCaption("Events per month");
getConfiguration().setTitle("");
getConfiguration().getChart().setType(ChartType.PIE);
setWidth("100%");
setHeight("90%");
DataSeries series = new DataSeries();
ArrayList<Evnt> events = (ArrayList)MockDataProvider.getEvntCollection();
Calendar cal = Calendar.getInstance();
HashMap<String, Integer> eventsPerMonth = new HashMap<String, Integer>();
Long id = 1L;
String month;
for (Evnt e: events) {
cal.setTime(e.getStartDateTime());
month = cal.getDisplayName(Calendar.MONTH, Calendar.LONG, Locale.ENGLISH);
// TODO bugged!
if (eventsPerMonth.get(month) != null) {
eventsPerMonth.put(month, eventsPerMonth.get(month) + 1);
} else
{
eventsPerMonth.put(month, 1);
}
}
Set<String> monthsOfYear = eventsPerMonth.keySet();
for (String m: monthsOfYear) {
series.add(new DataSeriesItem(m, eventsPerMonth.get(m)));
}
getConfiguration().setSeries(series);
}
}
