Issue with new Powerapps version 3.19014.8 - Dropdown values defaulting to Blank

[PSahu]

Hi Team,

There is a new PowerApps version (3.19014.8) which got published recently..it has completely messed up our apps. For all dropdown components, the default value has been coming as blank which is not how it was set when we created it. We did set all our default value to show the first value of the collection which is completely ignored now. it has messed up so many validations we added for a blank vs filled dropdown. The correct previous version was 3.19013.14.

Please help revert this change back or let us know an easy way to fix so many bugs which have appeared because of this upgrade.

Regards,

PSahu

Yes, I noticed the same. Now they show blank as default.
I did the following: 
For those that I didn't have a default value I added
Dropdown1.Default: First(CollectionName).ColumnName
and for those that I had a default value 
Like Dropdown2.Default: vDefaultValue
I changed it to
Dropdown2.Default: If(LookUp(CollectionName,vDefaultValue=ColumnName,true),vDefaultValue,First(CollectionName).ColumnName)

Yes. If this change will remain, then I have to fix the whole app (which is a lot of work) for lots of app. It is a lot of rework and complete end to end testing needs to be done again for each component.

I just wanted to reach the team to see if this issue can be reverted back or if an app setting can be switched off to not see this change applied.

That's why I'm pissed off. All my validations argh!

I agree. They should have informed us for a change like this one.

Same issue affecting myself. Luckily I've only updated a small app to notice it involvinf 2 dropdowns so easy to work around but this will break all my apps if I save any other's.

Any work on a resolution time?

Thanks,

Nicky

I just noticed a similar issue with cascading Combobox and Dropdown in an app we have in production. 

Scenario:

• Combobox:
  • Items:

    • Sort(
          Distinct(
              sharepointList, employeeID),
          Result
      )

• Dropdown:
  • Items:

    • Distinct(
          Filter(
              sharePointList,
              employeeID = comboBox.Selected.Result
          ),
          employeeLocation
      )

  • Dropdown is now completely blank when an employeeID is selected.
  • Worked fine for 8 months, now blank. No warning, no notice, just happened to stumble onto it.

Fix:

• Dropdown:
  • Left Items property the same
  • Changed Default property from "1" to:

    • First(
          Filter(
              sharepointList,
              employeeID = comboBox.Selected.Result
          ).employeeLocation
      ).employeeLocation

• Its weird to use .employeeLocation twice like that (probably the shape of my data), but it works.

Hope this helps!

I am having the same issue with my apps as well!!  All were working the day before yesterday and now all are broken.  Please resolve!!

This hurts my brain. I am hoping that someone who is smarter than me can help me resolve my similar situation.  I have a gallery being filtered by dropdowns whose sources are collections that list the distinct values of the filter.  It adds an "<All>" value which normally is the default but now it's broken.  Pardon me if I am about to do this wrong... first time posting here and not sure how you show the code in it's own box...

This creates a collection (StatusDropList) for the Dropdown based on the data from my gallery (FCDUserWorkStatus) using an OnVisible.  (I am just showing 1 of the 5 dropdowns that broke, otherwise they are all similarly executed):

ClearCollect(StatusDropList, {Result:"<All>"}); Collect(StatusDropList, Sort(Distinct(Filter(DirectoryData, FCDUserWorkStatus <> ""), FCDUserWorkStatus),Result, Ascending))

The default value of the dropdown is set to "1."

The items value is:    StatusDropList.Result

Can anyone guide me as to what I should try to modify to get this working again?

Thanks, John
