Title: Display description instead of value
Post by: bergsj on May 24, 2010, 11:50:52 PM

Hi there,

I'm using the lookup function which has a new feature called 'Display description instead of value'. This works great if you have a lookup table with an ID field in the Value field of the template and a nice description field in the Description field of the template.
In my case I do not use the ID field as the value field but only the Description field. When I select the record and press Select, the description is not shown.
This only works when I use the ID as the value field.

Is this by design or maybe a bug I am facing?

Any help would be appreciated.

OK let's narrow things down. This is because the lookup browse is using the Unique Key with ID as it's field. When adding a new Key in the DCT on the description field a specifying that in the browse it is working. However this is not a unique key so this is not a solution.

Hi Sjoerd,

Ok, I think I understand your situation - but let me see if I have it right.

You have a table (say "customers") which you are doing a lookup on. the customers table has a primary ket (some sort of Id) but what you're really interested in is the customer name.

Now you have a table (invoices) which will do a lookup on customers. You will get the customer name (not the id) and store this in the invoices record. However the customer name is _not unique_ (and hence the key on cusotmer name is not unique)?

Have I got it right?

Bruce, that's correct in your example I want to save the customername in the invoice record, not the ID. In that case it is not working.

Hi Sjoerd,

Try adding the assignment to the "More Assignments" list.

ie set up the lookup as-if you were gonna store the unique code part. So value = Id, Desc = Name and so on.
Then in the more assignments part set the Inv:Customer = Cus:Name.

(I'm intrigued that you're storing a non-unique part of a lookup record, but that's not really material to the answer.)

cheers
Bruce

Thanks Bruce,

Seems to work like a charm. I'm not able to actually save the record, but as soon as I'm done I will test if the non-unique value (it's a postal code for anonymous logging of request) is saved in the record and not the ID value.

Regards,
Sjoerd
