Hello, I am trying to implement a custompickerField, but I still don't understand very well how the suggestFunction and selectedLabels work since I have my DP_addressSugestion rule that receives the address and through the Google Maps API it already returns the filtering. Here is my suggestFunction.
a!localVariables( local!addressSugestion: rule!DP_AddressGoogleMaps( address: ri!address, latitud: -9.5, longitud: -75 ), if( local!addressSugestion.success, a!localVariables( local!labels: a!forEach( items: local!addressSugestion.result.places, expression: index(fv!item, "description", null) ), local!values: a!forEach( items: local!addressSugestion.result.places, expression: index(fv!item, "description", null) ), a!dataSubset( data: local!labels, identifiers: local!values, ) ), a!dataSubset( data: {}, identifiers: {}, totalCount: 0 ) ) )
Please help me to understand or some advices to work it

Hi everyone, I solved by myself, thanks
Can you share any details of what the issue ended up being, and what you did to fix it, for other users finding this thread in the future with similar issues?
No problem. As the documentation says, suggestionFunction requires a function that executes a filtering or search rule for a certain array, and this function returns a datasubset with data and identifiers. In the case of Google Maps, this is much simpler since the API does the filtering for you, so you don't need to do much work. I'll leave the code for the ruleExpression and the interface.
a!localVariables( local!addressSugestion: rule!DP_AddressGoogleMaps( address: ri!address, latitud: - 9.5, longitud: - 75 ), if( local!addressSugestion.success, a!dataSubset( data: a!forEach( items: local!addressSugestion.result.places, expression: index(fv!item, "description", null) ), identifiers: a!forEach( items: local!addressSugestion.result.places, expression: index(fv!item, "description", null) ), ), a!dataSubset(data: {}, identifiers: {}, totalCount: 0) ) )
a!pickerFieldCustom( label: "Direccion Asistencia", suggestFunction: rule!DP_addressSugestion(address: _), selectedLabels: local!origin, value: local!origin, saveInto: { local!origin }, maxSelections: 1 )
