Hello,
I've got a table for categories and another for items in those
categories. Now I want to create a very simple form: a dropdown list for
the category names and a grid showing the most important fields of the
items table. The grid should always show the records belonging to the
category chosen in the dropdown list. So I use the bizobj for the
categories table as parent and the bizobj for the items table as child
bizobj.
I don't think the way to populate the list shown in the wiki is the
right way for this case (or is it?). I tried simply to create the
dropdown list like this:
dl = dabo.ui.dDropdownList(pn, DataSource="rubrik",
DataField="rub_name")
dl.ValueMode = "String"
But that doesn't work. When I open the application, I get this:
Traceback (most recent call last):

So how to do this?
Thanks for pushes in the right direction,
