Me too. I am a newbie to jCook and cannot figure out how to get the Combo box in a form to populate from a foreign key.
Bizarrely if I enter a value into the combo box (a select box) I can get the correct foreign table values, but I can't seem to get the foreign key ids to appear so I can select ... and in any case how can I enter a value in a combo box?
Update - I just realised that the field in the form is a text field (which explains why I can type in it) and yet I have specified Combo Box. Any Ideas why it renders the wrong field type?
