The below code is throwing the above error. Please advise a correct way of doing this. using a dropdown column in a Grid. Grid rows are in a foreach loop and dropdown saveinto has another nested foreach loop and how to map the rights values to be able to change the preselected values and save.
rows: a!forEach( items: local!sources, expression: { a!gridRowLayout( id: fv!index, contents: { a!textField( value: local!sources[fv!index].DisplayName, saveInto: local!sources[fv!index].DisplayName, refreshafter: "UNFOCUS" ), a!textField( value: local!sources[fv!index].FullName, saveInto: local!sources[fv!index].FullName, refreshafter: "UNFOCUS" ), a!textField( value: local!sources[fv!index].Description, saveInto: local!sources[fv!index].Description, refreshafter: "UNFOCUS" ), a!multipleDropdownField( label: "", choiceLabels: local!sources[fv!index].Technologies.Name, choiceValues: local!sources[fv!index].Technologies.Id, value: { local!sources[fv!index].Technologies.Id }, saveInto: a!save( local!sources[fv!index].Technologies, a!forEach( items: save!value, expression: { Id: fv!index, DisplayValue: displayvalue( fv!index, local!sources[fv!item].Technologies.Id, local!sources[fv!item].Technologies.Name, null ) } ) ) ),

Hi
as per your code I think you are trying to save Technologies.Name associated with selected Technologies.Id.
to do so
don't use second loop since you are saving at index,
a!save(local!sources[fv!index].Technologies, local!sources[fv!index].Technologies.Name)
or you can use apply function
a!save(
local!sources.Technologies,
apply(displayvalue(
_,
local!sources[fv!item].Technologies.Id,
local!sources[fv!item].Technologies.Name,
null
),save!value
)
