附加信息

This issue seems to only happen when multiple queries with differing field options are executed simultaneously. If the minimum fields query is executed after the load all query is executed, but before it completes, the results seem to get modified such that the non-minimum fields are all null.

解决办法

Apply the 'Enums.QueryFeatureFieldsMinimum' enumeration to the feature layer before applying the 'Enums.QueryFeatureFieldsLoadAll' enumeration to solve the issue.

Example:

Apply the first enumeration: featureTable.queryFeaturesWithFieldOptions(queryParameters,Enums.QueryFeatureFieldsMinimum)

Apply the second enumeration:

featureTable.queryFeaturesWithFieldOptions(queryParameters, Enums.QueryFeatureFieldsLoadAll)

After running the application, the issue is not reproduced.

The query does not return null values for the fields of the feature layer:

qml: {"address":"1800 WASHINGTON ST","district":"2","objectid":13032690,"req_date":"09/17/2009","req_id":"506763","req_time":"08:15","req_type":"Graffiti Complaint - Public Property","status":1}
