Using value in segment causes NPE #72

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?  If applicable, please provide a
mapping configuration and sample record input to recreate the problem.
1. Using attached beanio.xml and examplefile.txt
2. Attempt to parse file
3.

What is the expected output? What do you see instead?
Fails to run, returns a NPE.

This will work however if i remove the value="statusCode" and instead replace 
it with a class that has both of the segment's fields in it.

Same issue occurs if i use value and collection="list"

What version of BeanIO are you using? What JDK version?
BeanIO-2.0.5
JDK 6

Please provide any additional information below.

A NPE is never good (and definitely a bug), but try assigning a type to those 
fields:

  <field name="reasonCode" type="string" length="2" />
  <field name="statusCode" type="string" length="2" />

Thanks,
Kevin
