Unresolved Compilation Problems - no other information

Anonymous — Fri, 18 May 2012 04:02:14 GMT

I'm trying to build a tMap component that maps 4 incoming values: accountID (String), deviceID (String), timestamp (Long), and statusCode (int) into a single output value, pk (String), as follows:
pk = accountID_deviceID_dateString_statusCode
where accountID and deviceID have been padded with spaces to 32 characters, and dateString converts timestamp from a long to a date string of the form YYYY-MM-DD HH:MM S
To do this, I'm using the following expression:
row1.accountID+StringHandling.SPACE(32 -StringHandling.LEN(StringHandling.TRIM(row1.accountID)))
+ "_" +
row1.deviceID+StringHandling.SPACE(32 -StringHandling.LEN(StringHandling.TRIM(row1.deviceID)))
+ "_" +
TalendDate.formatDate("yyyy-MM-dd HH:mm:ss",TalendDate.parseTimestamp(row1.timestamp))
+ "_" +
DataOperation.DTX((int)row1.statusCode)
Where TalendDate.parseTimestamp is a method I added to TalendDate:
public static Timestamp parseTimestamp(long arg) {
Timestamp timestamp = new java.sql.Timestamp(new Long(arg)*1000);
return timestamp;
}
The thing is, every line in the above expression works when run independently. However, when I put it together as above, I get an "unresolved compilation error" with no additional information (no java error indicated)
Any suggestions?
Thanks,
Steve

Hi Steve
If you got a compilation error, open the Code tab and then you will see which line has the error and the prompt error message.
Best regards

Hi Shong,
Thanks for the quick response. I'm not seeing any hard errors in the code tab - see attached screenshot. Just some generic type and static method warnings. I have also atttached shots of the tMap_1 screen and the expression builder screen. The latter shows the compilation error that results after hitting the "Test!" button.
Thanks
Steve

Sorry, here's the expressionbuilder and tMap screenshots

It's probably not a real error. I get this lots of times when testing expressions. It's probably a bug in expression builder. So long as the job runs ignore it.

Thanks janhess, turns out you're right. Despite the "unresolved compilation problems" error using "Test!," the code runs fine when executed. Now I know to just ignore that error unless there are actual errors indicated in the code.
