Applies To Product(s): OpenPlant PID Version(s): 08.11.10.523 Environment: Windows 7 64 bit Area: Component Subarea: Placement Original Author: Harpreet Singh, Bentley Technical Support Group Background When user upgrade their projects from OPPID build 427 or lower to build 523, they are not able to place the valves and an error message is displayed in message center. Error Message : LOG_ERROR - Bentley.Plant.ModelingFramework.ObjectModel - Exception : The Property 'IsFixedOriginOffset' is null in ECInstance {CellData(VGATE)} Stack Trace : \n at Bentley.ECObjects.Instance.ECBooleanValue.get_BooleanValue()at Bentley.ECObjects.Instance.ECBooleanValue.get_NativeValue() at Bentley.Plant.ApplicationFramework.Schematics.Cells.Utility.ConvertStructValueToActuatorData(ECStructValue structValue) at Bentley.Plant.ApplicationFramework.Schematics.Cells.Utility.GetActuatorLocationData(String libraryName, String cellName) at Bentley.Plant.ApplicationFramework.Schematics.SchematicsApplication.GetActuatorLocationData(ISchematicsInsertableComponent component) at Bentley.Plant.Application.Pid.Catalog.BaseValve.AddPoints() at Bentley.Plant.ObjectModel.Component.CalculatePointsAndCreateShape() at Bentley.Plant.ObjectModel.Placement.StartPlacement() at Bentley.Plant.ObjectModel.Model.InsertComponent(IComponent comp) This error is thrown because it is not able to get the required actuator location data from Valves.cel.sch.ecinstance.xml file. In OPPID 523 build, actuator data has been added in this file for each valve and since the projects upgraded from 427 or lower builds don't have this data therefore users get the above error while placement. If you compare the old Valves.cel.sch.ecinstance.xml file with the file from default projects, you would see the differences as highlighted in below picture: Solution To resolve this issue, you can add this missing data into your Valves.cel.sch.ecinstance.xml file. This can be copied from the same file of default project. Comments or Corrections?
