--------------------------------------

             Summary: camel-bindy doesn't pad fixed length records
                 Key: CAMEL-9476
                 URL: https://issues.apache.org/jira/browse/CAMEL-9476
             Project: Camel
          Issue Type: Bug
          Components: camel-bindy
    Affects Versions: 2.16.1
            Reporter: Jostein Gogstad


Reading CAMEL-6039 one gets the impression that camel-bindy will pad fixed length records if the input record is smaller than the fixed length.

https://camel.apache.org/bindy.html:
{quote}
When the size of the data does not fill completely the length of the field, we can then add 'padd' characters.

This is not the case as the following test demonstrates. It fails with
{code:none}
java.lang.IllegalArgumentException: Size of the record: 5 is not equal to the value provided in the model: 10
