I get TxPlanningObjectFieldNotLoadedException while i try to read a field value with GetField function of a TxPlaningObject in disconnected mode. I have tryed to load the fields with ImportFields method of the TxOfflineGlobalServicesProvider, but it has not helped.
To get field values in Process Simulate Disconnected, the psz file need to contain that values.
When the psz is saved from Process Simulate on eMServer, make sure that in Options, eMServer -> Save As -> Save attributes to psz check box is checked. This way the field values are exported to the psz and can be read.
