i used line combiner to join more than segment line and lines intersects with another lines

each line has around seven segment line so i used line combiner to join more than segments of line and also join the next line that intersects.

so i have now long line and it is working so nicely but i have still question if i need also to export the id of each line that intersects with next line to make long line .

so if 5 lines intersectes in nodes so i need id for each line that intersected with neighbour line.

so as example for 5 lines connected

i need five lines id plus the whole new id for the long line that contains 5 old id line.

really i learned alot from FME Community and from members

Thanks alot

There's the option to generate a list in the LineCombiner's parameters. You can then use a ListConcatenator to combine those list elements into a new attribute.

thanks for reply , i did what u said i got id but honestly exactly what i need

may be in the map has 50 lines and each 10 lines is connected so i combined lines and i have now 10 long lines, but i want to get from each long line the numberof id in it and let me know which long line included this lines and also give special colour for each long line is different colour from another long line

 

but as u told me , i got a list but i do not know .which one for which long line this is my problem and thanks
