Using forEach correctly [message #1735701]

I used a forEach in my list but it seems that it deletes the elements.

val x = resource.allContents.toIterable.filter(typeof(Directory))
// x.size here is 5.
x.forEach[isPersonal = true] // set the variable isPersonal to true.
// x.size here is now 0.

What am i doing wrong?

this is a flaw of the toIterable extension.
it creates an iterator that iterates only one.

solution:

make a copy of the iterable e.g.

.toIterable.toList
