----------------------------------------

    Attachment: Derby-268.diff

Hi Rick,
Thanks Rick the previous comment was exactly describing what I want to know.
I did some work on this and came up with a patch which is not fully completed.  
I use the following method to get the tableElementList. But it gives a TableElementList, which has zero elements.

TableElementList tableElementList = (TableElementList) nodeFactory.getNode(
                                            C_NodeTypes.TABLE_ELEMENT_LIST,
                                            getContextManager());

Is it a incorrect way to get the table element list. 
And  please take a look at the code and let me know your ideas.
thanks
