Kevin, thanks for the input and the advice.
When I add the following code to application.dryml, I get the exact
same form which is to say that I can add Bars to Foo, but only Bars
that I create on the new or edit Foo form, i.e. I cannot add
previously created Bars.
<extend tag="form" for="Foo">
<old-form merge>
<field-list:>
<bars-view:>
<select-one:/>
</bars-view>
</field-list>
</old-form>
</extend>
If I remove the : from the select-one tag, I get a stack trace leading
me to rapid_forms.dryml:645, claiming that view_hints is undefined.
view_hints is used there to to give the name of the model when no
objects of that model exist, but I have 3 Bars already created.
