Hi,
I am using a nested foreign key strucutre -like the one in your demos- so I have bookings and each booking have an individual assigned to it and each individual is located in a county. So there are three tables: bookings, individuals, counties. The I add a combo box to filter the list by individual, I get the following:
Without ajax: The drop-down is correct, but the text for the individuals is invisible. I can see the counties, and the number or rows for individuals is correct, but the names of the individuals is missing. The selection works, so if I pick an individual (whose name I can't see) the result is correct. It seems that this is not an issue without nesting, i.e. if I only have a foreign key pointint to a talbe with doesn't in its turn have a foreign key I don't get this.
With ajax: With Ajax I have to click twice which is not as elegant as a single drop-down with sub-headings. So I get a drop-down with counties and them when I have selected the county, I get a second drop-down with individuals. Again, in this second drop-down I can't see the names of the individuals. The rows are there, but I don't see the text. Also, it is not possible to reset the selection in ajax without clicking the clear button.
You can have a look at "manage bookings admin" in the component "bookings ver 2".
Grateful for any help!
