Hi
Wondering if anyone can help?
I've noticed over the past week or so that when i create new apps the drop downs are not populating in the Web Player but it works fine in the design studio. I have tried it on various devices andriod, ios and different web browsers all yeild the same results.
Background:
Azure SQL Server
Populating the dropdown via a collection, the collection is populated on Start of the application. I have also tried OnVisible both producing the same results.
I'm not doing anything different to what I have done in previous applications which work fine. The problem does not happen on every app created, thus making it hard to troubleshoot. Any pointers on what to check to try and resolve the problem would be appreciated.
There are no errors occuring when running the application(s) in the web player or mobile devices, just an empty dropdown column.
I have also tried adding a new dropdown and publishing, on occassion the drop down works and then stops again when published again.
Is anyone else experiencing the same?
If any further information is needed, do let me know and I will post.
Thanks
Solved! Go to Solution.
I am also having this issue. My Process :
On app start > ClearCollect( directory , 'SQL dbo' )
Dropdown > Allowed Values = directory
This seems to have worked fine with other apps in the past no problem, but now I am running into the same issue that you are. The dropdown items will populate in the web developer, however, in the web player or on mobile I get fields populated with blank values.
Will try and troubleshoot this and get back to you if I find any solutions.
Edit : It seems to be an issue with the ClearCollect() calling of the directory. I've had this issue before with Collections from a SQL DB not populating properly, you can find the solution in this thread
Tldr; turn off the Advanced setting "Explicit Column Selection" .... that should fix your problem!
I saw something similar. I took a functioning app and did a SaveAs to a new name. The newly saved app has issues rendering values in the drop downs (the original does not). I am populating the dropdown via filter on a SharePoint list (cascaded values from another drop down). The drop downs actually have values in them, but they are displaying blanks (meaning I can select 1 of 6 "empty" rows from the dropdown).
I have also noticed other dropdowns where the selections get "disconnected" from the original dropdown. Meaning the display of the dropdown list when opened may be 3-4 fields below the actual drop down field.
