Question

var items = job.getItems();
for (var item in items)
    job.removeItem(item);

And CF / Java throws

java.util.ConcurrentModificationException
at
java.util.AbstractList$Itr.checkForComodification(AbstractList.java:372)

What’s the cleanest way to remove all items without ConcurrentModificationException?

Thank you!

Answer 1

A java List has an (optional) clear() method.

The code would then become :

 job.getItems().clear()

AFAICS coldfusion9 uses hibernate as ORM, and hibernate does implement clear on the List abstraction, and will even translate it to a single DELETE statement to the database.
