Hi

It's possible the tMap catch the line number that it's being processed? My goal is to inform which lines of the file dosn't meet the constraints ...

$nb_line_tFileInputDelimited_1 should be fine 🙂

I have a similar problem (but with Java).
I have a tFileInputDelimited followed by a tMap (connected by a Main connection).
Within the tMap I need to catch the current line number of the tFileInputDelimited.
I used:
((Integer)globalMap.get("tFileInputDelimited_1_NB_LINE"))
but it crashes at runtime with a Null Pointer Exception.
I think this is because the NB_LINE is defined "after" the tFileInputDelimited input loop and not "during" the loop.
Someone can tell me if it's possible to catch the current line number during the loop?

Hi,
you could add a line number with Numeric.sequence to your stream (in a tMap for example).
