I’m trying to run an RPC call from the client to the gateway to return a dataset, but I keep getting a deserialization error.
Here is my gateway implementation:
protected Dataset getRecordsImpl() {
List<CustomRecord> records = getCustomRecords(); // returns list of records from internal db
String[] names = {"Id", "Name", "Description"};
Class[] types = {Long.class, String.class, String.class};
Object[][] data = new Object[records.size()][3];
CustomRecord record;
for(int i=0; i < records.size(); i++) {
record = records.get(i);
data[i][0] = record.getId();
data[i][1] = record.getName();
data[i][2] = record.getDescription();
}
return new BasicDataset(Arrays.asList(names), Arrays.asList(types), data);
}Stack Trace:

java.lang.reflect.UndeclaredThrowableException: java.lang.reflect.UndeclaredThrowableExceptionWhy am I getting a number format exception for a string column? Is there a better way to build datasets like this?
