If this is the exact code you have written in the child interfaces, then let me tell you, you cannot use the key "contents" without any container layouts. Try removing that keyword and just keep the interface definition in curly braces. {
 a!sectionLayout(
 label: "פרטי מבקש האשראי",
 contents: {
 a!columnsLayout(
 columns: {
 a!columnLayout(
 contents: {
 a!textField(
 label: ": מזהה התאגדות",
 labelPosition: "ADJACENT",
 value: ri!customer.Identification_Itagdout,
 saveInto: ri!customer.Identification_Itagdout,
 refreshAfter: "UNFOCUS",
 readOnly: true,
 validations: {}
 ),
 a!textField(
 label: ":שם התאגדות",
 labelPosition: "ADJACENT",
 value: ri!customer.Name_Itagdout,
 saveInto: ri!customer.Name_Itagdout,
 refreshAfter: "UNFOCUS",
 readOnly: true,
 validations: {}
 ),
 a!textField(
 label: ": טלפון ",
 labelPosition: "ADJACENT",
 value: ri!customer.Telphone_itagdout,
 saveInto: ri!customer.Telphone_itagdout,
 refreshAfter: "UNFOCUS",
 readOnly: true,
 validations: {}
 ),
 a!textField(
 label: ":מייל ",
 labelPosition: "ADJACENT",
 value: ri!customer.Mail_itagdout,
 saveInto: ri!customer.Mail_itagdout,
 refreshAfter: "UNFOCUS",
 readOnly: true,
 validations: {}
 )
 }
 ),
 a!columnLayout(
 contents: {
 a!textField(
 label: ": סוג התאגדות",
 labelPosition: "ADJACENT",
 value: ri!customer.Type_Itagdout.Name_Incorporation_Type,
 saveInto: ri!customer.Type_Itagdout,
 refreshAfter: "UNFOCUS",
 readOnly: true,
 validations: {}
 ),
 a!textField(
 label: ":תאריך התאגדות",
 labelPosition: "ADJACENT",
 value: ri!customer.Date_Itagdout,
 saveInto: ri!customer.Date_Itagdout,
 refreshAfter: "UNFOCUS",
 readOnly: true,
 validations: {}
 ),
 a!textField(
 label: ":מגזר פעילות",
 labelPosition: "ADJACENT",
 value: ri!customer.Sector_Activity.Name_Activity,
 saveInto: ri!customer.Sector_Activity,
 refreshAfter: "UNFOCUS",
 readOnly: true,
 validations: {}
 )
 }
 )

 }
 )
 }
 )
} 
 And do similar with the other interface. The error should then be resolved.
