I am using the following xPath constraint (in bold) as the Data source for a DataGrid, however it does not filter correctly returning the complete list instead of the filtered list. Has anyone an idea of why this is please? [Demo.Issue_Asset/Demo.Asset/Demo.Asset_LOPA/Demo.LOPA/Demo.Fleet_LOPA/Demo.Fleet/Demo.Fleet_FleetFamily/Demo.FleetFamily/Demo.FleetFamily_AircraftType/Demo.AircraftType] [Demo.Issue_Asset/Demo.Asset/Demo.AssetComponent_Asset/Demo.AssetComponent/Demo.AssetComponent_Component/Demo.Component/FailCategory = 'A'] [Status != 'Done'] Thanks for any help.
