Building off of http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#QueryRelatedRecords I have a single feature class that is joined to an sde table with a one to one relationship; I also have this feature class related to a different table (1 to many relationship). When I try to retrieve the related data I get the error "Query execute error: Error code '400': 'Invalid or missing input parameters.'". I can't seem to find anything wrong in the code. I was wondering in the following code if the call for ObjectIds is different if there is a table that is joined to the feature class: //Relationship query
RelationshipParameter relationshipParameters = new RelationshipParameter()
{
ObjectIds = new int[] { Convert.ToInt32(g.Attributes[SelectedRoadsTreeView.Tag as string]) },
OutFields = new string[] { "loc_id, count_id, _year, adt" },
RelationshipId = 2,
OutSpatialReference = Map.SpatialReference
};I did notice in the service the fields are displayed with the feature layer or table name before the field name. This made a difference when I was pulling the fields to display in the data grid. Thanks in advance for your help.
