Length of drop down list

Wiki

I was wondering if it was possible to get the count of items in a dropdown list in the architect. So I can use it in a popup dialog.

For instance when the user selects a beneficiary the bankaccounts dropdown list to choose from update to the possible bankaccounts. Most of the time there is just one so it automatically selects the correct one, but when there are more we want a popup that makes the user aware that there are ‘n’ bankaccounts to choose from where ‘n’ is the count of items in the dropdown list.

Is this possible? Or Is there another way to achieve what I want?

Hello,
Can’t you just use a Cache-element (Process variables), doing a count on the same expression as the dropdown? This will give you the number of results?

Then, you can put this on an OnChange, and then, when the count = 1, pre-select is. When the count > 1 (or <>1), show a pop-up.

Hi Joost!

I didn’t think about that solution. Way easier! Thank you :slight_smile:
