Ok, but why does the generator creates the following:
public er.extensions.foundation.ERXMutableArray ordernummers() {
return (er.extensions.foundation.ERXMutableArray)
storedValueForKey("ordernummers");
}
Is ordernummers an attribute or a to-many relationship? If it is a to-
many relationship, this is normal. If this is an attribute, you have
a problem. The generator just generates what you have modeled. If
you model bad things, it will happily generate them.

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?

Hi,
In my Entity, one of my Attributes has mutableArray as prototype.
See Commandment 7:
http://wiki.objectstyle.org/confluence/display/WO/EOF-Using+EOF-The+EOF+Commandments
See page 32 of Practical WebObjects.
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:

Hi,
When setting a ERXMutableArray to a ERXGenericRecord,
What do you mean by "setting a ERXMutableArray to a
ERXGenericRecord"?

I suddenly get the following error:
Where can I find what is going wrong, it used to work.
