A sligthly modified patch from Jonatan Soto for "ConcurrentModificationException when cancelling an order" https://issues.apache.org/jira/browse/OFBIZ-5194

After the order gets cancelled, there is a loop in OrderView.groovy@122 that removes promotional order line items retrieved from the OrderReadHelper class when cancelled. This is what makes the ConcurrentModificationException to be thrown.

For further details, check out the following thread at the dev mailing list: http://ofbiz.markmail.org/message/vmm65cmbf5hkmqm6?page=2

jleroux: I simply put a comment and removed the useless temporary orderItemListFiltered variable
