Saving Map variable in editable grid

Question

Hi, 
 I have a local variable with Map type. I have 2 fields inside a variable (Field label and Field Type) 
 I need to save the variable in a loop by clicking on the Add dynamic link. Please help me out here since the current code is not working. 
 local!manualDynamicField:a!map(
 manualdynamicFieldLabel:"",
 manualdynamicFieldType:""
 ),
 
 a!gridLayout(
 label: "Manual Dynamic Fields",
 labelPosition: "ABOVE",
 headerCells: {
 a!gridLayoutHeaderCell(label: "Field Label"),
 a!gridLayoutHeaderCell(label: "Field Type"),
 a!gridLayoutHeaderCell(label: "")
 },
 columnConfigs: {
 a!gridLayoutColumnConfig(width: "MEDIUM"),
 a!gridLayoutColumnConfig(width: "MEDIUM"),
 a!gridLayoutColumnConfig(width: "ICON")
 },
 rows: a!forEach(
 local!manualDynamicField,
 {
 a!gridRowLayout(
 contents: {
 a!textField(
 label: "",
 labelPosition: "ABOVE",
 value: index(fv!item,"manualdynamicFieldLabel",{}),
 saveInto: {
 a!save(
 index(fv!item,"manualdynamicFieldLabel",{}),
 concat("###", save!value, "###")
 ),
 a!save(
 local!manualDynamicFieldToAdd,
 difference(
 index(local!manualDynamicField,"manualdynamicFieldLabel",{}),
 local!manualDynamicFieldCopy
 )
 ),
 a!save(
 local!manualDynamicFieldToRemove,
 difference(
 local!manualDynamicFieldCopy,

The local!manualDynamicField which you are trying to append in the addRowLink(line 201) is not an array. Updating the locallocal!manualDynamicField to have "{}" surrounding the a!map() will be required as follows. 
 local!manualDynamicField:{
 a!map(
 manualdynamicFieldLabel:"",
 manualdynamicFieldType:""
 ) 
}, You will also cannot save data into an index(). e.g. index(fv!item,"manualdynamicFieldLabel",{}), 
 a!save(
 index(fv!item,"manualdynamicFieldLabel",{}),
 concat("###", save!value, "###")
), So you will have to update to reference the dot operator syntax fv!item.manualdynamicFieldLabel1
