Any news on this topic? I had just build a nice form. After i add two new look up columns al my columsn are not working anymore, very very strange. I just deleted the datasource and remove/add all the code for the items. I doenst look this will fix the error.
Has someone registered a ticket by Microsoft for this?
@pvanolinda @msspdev @gmaasz @Vinoj3683 @LouisaDW @johnom @Monty_Baird @WilliamVingaard @HillaRamo @Anonymous @longathrow Hi all--sorry for the inconvenience this is causing. We have identified what we believe to be the root cause of the issue and are currently validating a few. It should be available shortly for release to production.
As we understand it, the issue may occur sometimes when the data source that a ComboBox control is bound to is either (a) refreshed, or (b) removed and then added again. The current advised mitigation that has seen success with customers is to perform the following actions after refreshing or removing/adding a data source:
This should allow the ComboBox controls to be correctly reconfigured to the correct values.
Also, if your ComboBox control contains only a small number of values, it is advised to disable IsSearchable since (a) this incurs a slight overhead when enabled, and (b) the issue of empty values only occurs when IsSearchable=true.
Update: We have committed a fix that we believe will resolve this issue. It is currently expected to be deployed to all production regions during the week of October 21st. I will update this post again once it has been deployed.
@pvanolinda @msspdev @gmaasz @Vinoj3683 @LouisaDW @johnom @Monty_Baird @WilliamVingaard @HillaRamo @Wackmack88 @longathrow @ravievg @irawanfajar The fix for missing items in ComboBox drop-downs has been deployed to all production regions with Studio release 3.19101. You will need to edit and re-publish your app(s) for the changes to take effect.
@_Corey_ This solution worked 4 hours ago when you posted it, but now my app is showing the red x's again and the following the same solution procedure does not fix it.
