Unable to Reproduce
I have exported some transactions from our accounting systems into tab separated file. As far as I can see if I have an empty column in the file, JasperETL does not count this column. For Example the line
is transformed into 2 columns, not into 3. This is a big problem for us.
I've tried to reproduce your situation. I created file with the follow content:
Added tFileInputDelimited and tLogRow and connected them. Also I've added a generic schema with 3 fields - id, field, value - and set it to tFileInputDelimited. In tFileInputDelimited I've changed "Field Separator" to "\t".
When I run it, this what i've got.
Starting job job_import_tab at 13:25 06/05/2009.
Job job_import_tab ended at 13:25 06/05/2009. [exit code=0]
So, seems like it's work for me. I used JasperETL (2.3.2.r12707)
