Hi again, thank you for the quick answers. I think I have been able to replicate the problem in an easy way. I have built some test cases and I have found the one in which I'm having trouble. The "required=false" option is working for me always except in one case.
This case is when the two missing fields occur at the end of a line at the same time. I'm going to explain it with my test cases. I have built a simple route for my unitary tests: from(URI_START_PROCESS) .unmarshal().bindy(BindyType.Csv, "com.mypackage") .to(URI_END_PROCESS_MOCK); My class (I have only one) in "com.mypackage" has the following annotations: @CsvRecord(separator="\t") from positions 1 to 5: @DataField(pos = N, required = true) for positions 6 and 7 : @DataField(pos = N, required = false) (so fields 6 and 7 are optional) Test Cases: Case 1: Processing two lines with ALL the fields (Works like a charm) String data2Process = "data1\t14700\t2011-10-04 04:00\t5\t1\t5\t9\ndata2\t14700\t2011-10-04 05:00\t49\t2\t5"; Case 2: Processing two lines. In the first line the 6th field is missing (works perfectly) String data2Process = "data1\t14700\t2011-10-04 04:00\t5\t0*\t\t*0\ndata2\t14700\t2011-10-04 05:00\t149\t0\t0"; Case 3: Processing two lines. In the first line the 7th field is missing (works perfectly) String data2Process = "data1\t14700\t2011-10-04 04:00\t5\t0\t0*\t\n*data2\t14700\t2011-10-04 05:00\t149\t0\t0"; Case 4: Processing two lines. In the first line, both 6th and 7th field are missing (is not working) String data2Process = "data1\t14700\t2011-10-04 04:00\t5\t0*\t\t\n*data2\t14700\t2011-10-04 05:00\t149\t0\t0"; I also tried a variation of Case 4, in which I made field 5 also not required and the missing fields were 5th and 6th, in this case there were no problems. The exception is the one I said before: "Some fields are missing (optional or mandatory), line:1" -- View this message in context: http://camel.465427.n5.nabble.com/Bindy-Having-trouble-with-the-required-field-tp5597196p5603131.html Sent from the Camel - Users mailing list archive at Nabble.com.
