Hi,

I tried 'addObjectToBothSidesOfRelationshipWithKey'  and I still have
the same problem.

Let me also tell you another scenario where I am using a similar one.
   In this case,  I have two tables "Projects" and "Keywords" which are
flattened and the new table name is "ProjectKeyword".

In the projects page, I have a WOCheckBoxList, which displays all the
Keywords.     The WOCheckBoxList has the following definition.

CheckBoxList1: WOCheckBoxList {
	displayString = currentKeyword.keyword_name;
	item = currentKeyword;
	list = fetchKeyword;
	selections = currentProject.toKeywords;
	suffix = "  ";
}

where "fetchKeyword" is a method that returns a list of all Keywords.
   The above definition made my job so easy in WebObjects 4.5, that I
did not write any other piece of code to add / delete keywords to/from
the project.     Just a saveChanges did the wonderful job of inserting
records into "ProjectKeyword".  Now what should I do to have the same
thing working in WebObjects5.1.4.

Thanks,
Meena.
