Issue concatenating combo box Default selected Items

(0) ShareShare
ReportReport
Posted on by

Hello all, I am having an issue capturing/updating a concatenated string field from a combo box's selected items.

 

When I select a save button, the selected items of the combo box are saved to a string field via patch and then set as the default selected items the next time a user opens the app.

 

Here is an example of two selections made.

Here is the concatenated string field logic.

Here is the concatenated string field output. The names are hidden but they match the two selected items from the combo

This process works fine so far but my issue is when I reopen the app and try to add to the selected options/update the string field, I get the following string in return.

 

Here is the combobox with the original two sections preloaded to the default selected items, PLUS a new selection added.

and here is the what the concatenated string now looks like, it appears the original two items aren't being read in but are blanks separated by comas. Any ideas on how I can have this string update/retain the default selected items when attempting to update/add to the field?

 Thank you very much!

    Hi @JDH1381 ,

    I have struck this bug before (and it seems random) in other places and it seems that the issue is that you have not "selected" the other two items in this session. You will find if you delete the other two and re-select them, it will work. It also works fine initially (as you can see)  if you have not selected anything. It does not affect the saving of data, which works fine. I tend to point at the save list values, which always works.

    Thank for you for the reply, sir. This bug was caused by me using the "Rename Columns" function in order to have the output from the "Split" function I used populate the default selected items. The fields need to have the same column name as the items from the dropdown. My issue was that I renamed the column to "Value" rather than the actual field name from the dropdown. Once I updated that, it worked like a charm. Thank you very much.
