Oracle.jbo.ReadOnlyAttrException: JBO-27008

Question

Hello, friends!
I use uix for my application (generated with JHeadstart).
Now I have one problem, and this problem is very strange. Some of VOs throws exception after commit changes:
(oracle.jbo.ReadOnlyAttrException) JBO-27008: for one atribute, which is readonly and i did not try to update it.
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)
I don't know why, but all worked fine before.
I think that this is not view project problem. Because the same problem appear on the other pages (oracle.jbo.ReadOnlyAttrException: JBO-27008:)
and when i test model project with bc4j tester now. But sometimes this problem appears on the uix page testing and does not appear when i test this
VO with bc4j tester. For example, one my VO hane primary key: Id, updeteable=always, display=false and when i try to update another
VO in this page i recieve same error. This error appears for attributes which are always updatable and for attributes which
are readonly and when i do not update it.
Maybe you can tell me how to solve this problem, please.
Thank you.

Erik, thank you.
But I have not custom logic in the isAttributeUpdateable() method.
This attribute is transient (java.util.List). And the get attribute method is:
public List getMyList()
{        if (MovesListAdapter!=null)
return MovesListAdapter;
ViewObject vo = this.getApplicationModule().findViewObject("MyVO");
System.out.println(rowSetName);
RowSet rowSet = vo.findRowSet(rowSetName);
if (rowSet==null)
rowSet = vo.createRowSet(rowSetName);
rowSet.setWhereClauseParam(0,this.getIdOsnovanie());
rowSet.executeQuery();
rowSet.setRangeSize(-1);
String rowSetName = "MovesRowSet"+this.getIdOsnovanie();
System.out.println("MovesRowSet row count="+rowSet.getRowCount());
MovesListAdapter = new RowIteratorListAdapter(rowSet, true);
MovesListAdapter.setEmptyRowsAtTop(1);
List t=MovesListAdapter;
return MovesListAdapter;
}
