Not quite following that, but I did notice this in the ERXMutableArray
docs:
it is best if you use only List-methods when
* extending List-methods and NSArray methods in other cases.
Otherwise you will
* most likely get into stack overflows.
Which might explain Frank's original problem.

Just because you CAN select it does not make it safe to use. Anjo had
some way of using this safely, but you need to be aware that EOF is

None of this explains the StackOverflow. I think you have two
problems. 1: Using a mutable attribute. 2: Something causing the

Re: Prototype mutableArray savechanges error
Ok, but why does the generator creates the following:
public er.extensions.foundation.ERXMutableArray ordernummers() {
return (er.extensions.foundation.ERXMutableArray)
storedValueForKey("ordernummers");
}
public void
setOrdernummers(er.extensions.foundation.ERXMutableArray value) {
if (_Paklijst.LOG.isDebugEnabled()) {
_Paklijst.LOG.debug( "updating ordernummers from " +
ordernummers() + " to " + value);
}
takeStoredValueForKey(value, "ordernummers");
}
If I do aPaklijst.setOrdernummers(arORderNrs.immutableClone()); then I
get an error saying it should be an ERXMutableArray
How can I change that?

You want to be really, really sure you know what you are doing if
you use mutable values. Get it wrong, and EOF will have its revenge.
So if is set that Attribute and do saveChanges, the I get the
error. It was working in the past, so I think it might have
something to do with an update (nightly wolips?, wonder?)
I really don't now where to look.
Check for changes in ERXGenericRecord. Maybe something created an
infinte loop if you use mutable values:
