Multi-select combo box is adding an additional entry after save

Posted on by BG-15041758-0

Hello,

I have a multi-select field and am using a combo box on the app. There are hidden fields that show based on selection. When I go to view a saved form that had multiple selections, the combo box now had an additional selection and the hidden fields are not showing. The checked selection is the new one. The field doesn't allow for additional selections and search is off on the field. Has anyone seen this?

Hi @BG-15041758-0,

What I think is happening that when saving the form, the selected items in the combobox are saved as a comma separated string. Then, when viewing the saved form, the string is not converted back into the individual items, which is causing the behaviour as can be seen in your screenshot.

To fix this, try changing the formula for the DefaultSelectedItems property of the combobox to:

Split( Parent.Default, ", " )

I have used Parent.Default as I assume the combobox is inside a datacard within a form control, but if it is not, you can replace that line with whatever is currently set for the DefaultSelectedItems property.

Once this is working, the conditional visiblity of the other fields should be restored as well.

Please share the full code of the combobx (right click the control in the tree view and then select View code) if you need additional support.
