Question

Hi, 
 I am getting the following error " Could not display interface. Please check definition and inputs. Interface Definition: Expression evaluation error at function a!sectionLayout [line 4]: The contents field on a column layout cannot contain a form layout. Received a form layout at index 1. " when trying to complete the instructions on page 4 of Build an application step 10 of the process modeling 101 course. 
 
 See expression below. 
 a!formLayout( label: "New Maintenance Request", contents: { a!sectionLayout( label: "Vehicle Details", contents: {rule!AX_VehicleDetailsView(ri!vehicle) } ), a!sectionLayout( label: "Section", contents: {} ) }, buttons: a!buttonLayout( primaryButtons: { a!buttonWidget( label: "Submit", submit: true, style: "SOLID" ) }, secondaryButtons: { a!buttonWidget( label: "Cancel", value: true, saveInto: ri!cancel, submit: true, style: "OUTLINE", validate: false ) } ) )

Hi Devi , 
 Form layout is one of the top level layout. Inside that you cannot use again another form layout or other top level layout. In the section rules you have called in the main form, check if you have used form layout , if yes remove the a!formlayout and use a!sectionLayout or simply wrap all contents using {}.
