Blank value in combobox is not saved

[namnguyenkg]

Hi guys,

I have a combobox which is a SharePoint lookup field. The items in the combobox are searchable.

I have an issue as follows:

I set the combobox's value to blank by removing the selected item (click on X icon), then click on Save button, but the field stills keep old value (Kim Hage). 

Please give me your solution if you have any.

Thanks!

Hi @namnguyenkg ,

What is the column type of the source for this lookup column? I just tested with a text column as the source of the lookup field, and create the auto-generated app. In edit form, I cannot reproduce your issue. 

Did you create the app by Home > Start from data? If so, did you make any change to this field in edit form? 

Check if the Update property of this data card is:

DataCardValuexx.SelectedItems

If the issue persists, please delete this data card and readd it.

Regards,

Mona

Thank Mona,

I actually made some updates on the field in Edit form. The type of the source column is text.

For sure, I created another auto-generated app and I did not make any changes for this time. However the issue was still there.

I event tested with a combobox which is a Choice field, it still kept old value. The fields did not accept blank value.

I created the app as follows:
