One note : a .betwixt is only for the bean the .betwixt file is for. So if you use a Person bean which also contains an Address beean, Person.betwixt cannot be used to alter the address behaviour.

I wouldn't have expected this situation to be treated as a > cycle. The cyclic checking isn't that advanced yet. The scenario that A refers to another A is covered however. Since the cyclic stuff also has some relation when you use id's (and I am not into id's that much), I probably have to have some help with the id handling. Time to read some specs on that :) I'll will try to answer your questions in more details by updating the docs, which will describe the correct behaviour Mvgr, Martin -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
