Many thanks to all the people who offered suggestions. Those helped a lot to straighten out configuration problems. Funny thing - code truly started working only after I split single betwixt-config file into individual dotbetwixt files. Weird. I am not even sure I can formulate problem correctly to post it on developers list. Something to do with preloaded and cached configuration.
Thanks again.

Please help Try this <?xml version="1.0" encoding="UTF-8"?> <betwixt-config> <class name='com.my.CollectionWrapper' > <element name='elements'> <element property='elements' updater='addElement'/> </element> </class> notice that i changed 2 things: - the name of the property is elementS (plural), not element - I added an updater to specify the method that betwixt should invoke (it may be not necesary) I hope to be helpfull PS: Excuse my terrible english.
