Dropdown values are invalid choices

I have created some dropdowns which are being populated from data pages.

Data pages are using report definitions as a source.

The correct values are being populated, but when I click save or submit, page returns error that says selected values are invalid.

I have not set up any validation requirements for the field. I also tried to set an action configuration (Click - Post Value) but this did not help

Have you passed the parameters correctly to the datapage?

@KamineniSurya I believe so, I am getting the correct list of values. Example,selecting Building A in the first picklist will only show floors from building a, and changing the building, will change the available floors.

I remember I had the same issue a you few weeks ago

This is an example of a property using a dropdown populated by a Data Page wih a parameter.

If i recall correctly, I had to check the box: Display only (not for validation) save and run a couple of time then uncheck the box.

Hey, this worked for me. The cascading drop down is configured and working properly. I can also access the selected values to then update the dataset
