Webitems needs an iterator method; you're iterating over the object itself. If you want to iterate an int in a range, you have two options: for(i in 0..limit) { // x..y is the range [x, y] } Or. for(i in 0 until limit) { // x until y is the range [x, y> } Both of these creates an IntRange, which extends IntProgression, which implements Iterable. http://gordonbrander.github.io/iter/iter.html
