Thank you very much for the reply. I think I understand your method. To simplify things however, I would like to save the users selection as a column in the same table (parent) and not in a separate table (child)
Thus the column will get data like [1,4] from the multivalue widget, if the user chooses item ids 1,4 in the multiselect. The widget is using a set method in the fb:save that sets a property that is a Java Collection. My debug statments indicate it is trying to save something like this [1,4] or [3,6,8] and so on. so, to be more clear, I am trying to save a property of type java.util.Collection in a column of table Parent, in a postgresql db. thx Paul --- Joose Vettenranta <[EMAIL PROTECTED]> wrote: > > > > Basic question is - how does on persist a > collection > > to a postrgest table using jdo? > > Normally collection is just a 1:n connection to > another table, like > > create table parent (id integer); > create table child (id integer, parent integer); > > so you map parent to have collection Childs and then > that Childs > collection you map to be of that child table. > > - Joose > > -- > "Always remember that you are unique, just like > everyone else!" > * http://iki.fi/joose/ * [EMAIL PROTECTED] * +358 44 561 > 0270 * > > > --------------------------------------------------------------------- > To unsubscribe, e-mail: > [EMAIL PROTECTED] > For additional commands, e-mail: > [EMAIL PROTECTED] > > --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
