While converting shapefile to any format I am getting an error "IFMELine was given an index beyond its current range.". So I guess this must be to do with shapefile but I can open shape file in Data inspector. Could somebody please point out what is causing this error?
Any resolution?
Cheers,
John

The message says that the processing tried to access a vertex of the line by an invalid index. i.e. less than 0, or greater than or equal to the number of vertices. So I don't think there is a problem in the source shape file.
This error could occur when a bad script manipulates the line geometry. For example, assuming that the input feature has line geometry, the error can be reproduced easily using a PythonCaller with this script.

def badScript(feature):
line = feature.getGeometry()
point = line.getPointAt(-1) # Oops, invalid index was given!

What kind of transformers do you have in the workspace?

+15(i see often scripts that do this inadvertantly..)
Recently a colleague did this.
Buildingpoly as base for a neighbourfinder to a linenetwork.
Some buildings were donuts.
Causing the shapewriter to throw an error " an fme_line was etc.etc." (and of course no erros when validating the geo..because the objects themselves where geometricaly ok, just not the relating attributes))
Solution: detect donuts prior to some processes.
