java.lang.NullPointerException in TMap (value = 0 )

INESBK — Wed, 07 Mar 2018 10:52:09 GMT

Hi,

I get the error java.lang.NullPointerException because I have a field that contains 0 value(i think). However, I want to get this value so I don't want to filter the value=0.

So to catch the error I added the component tLogRow like the screenshot below.

The type of field quality is Integer.

tLogRow print 1546 row with quality=0 after that the job is crashing.

So I can't understand the cause of this problems and How can I resolve them?

Please help me!

Best regards.

Check if your attributes aren't null. For example, for attribute value: row1.value!=null

Hi,
0 is not null and it's not because you a 0 into a field that you have a java.lang.NullPointerException.
Carefully check for other fields which can be null and participate into expression into your tMap.
Strings are good candidates to generate this kind of error.

Hi,

Thanks for your replay.

I've checked all the fields but still have the same problem.
