Hi,
I worked on a small project in order to discover how things work for
couchbase-lite-java-1.2.0 on
Windows 10.
For this project I created a view and then put an object which was not an
instance of String as a key of the mapper here is the code snippet :
public void createEventsByDateView() {
View eventsByDateView = this.getView("eventsByDate");
if (eventsByDateView != null) {
eventsByDateView.setMap(
new Mapper(){
public void map(Map<String, Object> document,
Emitter emitter) {
if(document.get("location") != null){
emitter.emit(
new SimplePojo("location"),
document.get("location"));
}
else{
emitter.emit(new SimplePojo("mock"),
document.get("mock"));
}
}
}, "3"
);
}
printQueryToLog(eventsByDateView);
}
and here is the the SimplePojo :
private class SimplePojo{
SimplePojo(String string){
this.setString(string);
}
public String getString() {
return string;
}
public void setString(String string) {
this.string = string;
}
String string;
}
After running the app I've had this exception :
*Exception in thread "main" java.lang.Error: invalid class for JSON at

Must I use only use String as the key of the mapper on Windows ?
