Always Selected One in Qlik Sense

dineshraj — Wed, 04 Aug 2021 12:36:55 GMT

Hi Experts,

In my qlik sense application i used always selected one functionality. And I hid the fields with HidePrefix. After my data reload the always one selected functionality got removed. Can anyone tell why this is happening?. The below are samples of my script

Set HidePrefix='%'

Load

Month(Date)&' '&Year(Date) as MonthYr

From ....ABC.qvd;

Rename Field MonthYr into %MonthYr;

The steps I took were to :

Remove the hideprefix ( NB also consider using hidden script tag as it's more flexible )
Load the app as normal
Enable the field always one value property
Select the default value in a filter pane
Edit script and re-enable hiding
Load the app again

Also watch out if you export the app without data to save the QVF into Git, or even for deployment to higher environments - the property gets wiped ( as happened in QV list boxes ). Possible workaround is to config-drive the load script to allow a FIRST 1 or FIRST n load of each table, and save the vastly reduced app via QMC export.

You could argue it is expected behaviour rather than a bug - was always there in QV too. I guess the object loses the ability to have one value selected when there is no data in the app.
