When generating bi-directional support for a ordered 1:n-relation then there are some generated features handling the changes that need to be applied to the "n"-list.

The method "clearXYZ" seems to be generated incorrectly as it:
- iterates over the list with an foreach (for XYZ xyz : XYZs)
- and calls "removeXYZ" for every entry (which handles the bi-directional remove)

This consequently leads to an ConcurrentModificationException because the list ( which it currently iterates on) is being modified (entries are removed).

Imo there are two possible solutions:
- Iterate over a copy of the org. list (i.e. for (XYZ xyz : new ArrayList<XYZ>(XYZs))
or
- simply remove the first entry from the list until it is empty
Code: [Select all] [Show/ hide]

while (!XYZs.isEmpty()) {
 removeXYZ(XYZs.get(0));
}
