Problem with "Row-specific or Cascading Lists in Table Layout"

Question

Hello, friends!
I have read article "Row-specific or Cascading Lists in Table Layout" written by Steven Davelaar. I have maked several table layouts with this technique and it worked fine.
But now I have one problem, and this problem is very strange. One of VOs for which I use this table layouts throw exception after commit changes on first LOV attribute (Deptno). First time it was error
(oracle.jbo.ReadOnlyAttrException) JBO-27008: for atribute mgrList
at oracle.jbo.AttrValException.<init>(AttrValException.java:112)
     at oracle.jbo.ReadOnlyAttrException.<init>(ReadOnlyAttrException.java:40)
     at oracle.jbo.server.ViewRowImpl.setAttribute(ViewRowImpl.java:815)
     at oracle.jbo.jbotester.JboTesterUtil.setData(JboTesterUtil.java:173)
Then I setted updateable property of MgrList attribute to always and now i have this error:
oracle.jbo.domain.DataCreationException: JBO-25009: Cannot create an object of type:java.util.List with value:[{}]
     at oracle.jbo.domain.TypeFactory.get(TypeFactory.java:721)
     at oracle.jbo.domain.TypeFactory.getInstance(TypeFactory.java:85)
I don't know why, but all worked fine yestarday. And same code works fine for another VOs. And article Test application works fine too.
Help me, please.
Thank you.
