Multi Value CDT

Question

I've defined a CDT as a Multi Value. At run time I will have 'n' instances of the object. During runtime I wish to update a specific field for one of the instances of the object but I'm not seeing how to address the field correctly. 
 I cant use array[1].field as that's only addressing the first instance. So for example I have at run time the multi Value CDT with the values : 
 Instance1 Instance2 Instance3 
 Field1(Text) A D G 
 Field2(Text) B E H 
 Field3(Boolean) true false false 
 I want to change Instance3 Field 3 from false to true, (and ideally instance 1/2 to false)

Hello, 
 You can either modify the particular object and property within your process model using a script task node or within a SAIL form. 
 1. 
 
 2. Based on user actions you can modify the property of an object using a!save() function. 
 
 find the documentation in the following link: a!save() function 
 
 you can play with the following code: 
 load(
 local!animal_cdts: {
 {id: 1,description: "snake",isActive: true},
 {id: 1,description: "dog",isActive: true},
 {id: 1,description: "cat",isActive: true} 
 },
 a!formLayout(
 contents: {
 a!gridLayout(
 headerCells: {
 a!gridLayoutHeaderCell(label: "Description"),
 a!gridLayoutHeaderCell(label: "Status"),
 a!gridLayoutHeaderCell(label: "")
 },
 columnConfigs: {
 a!gridLayoutColumnConfig(weight: 6),
 a!gridLayoutColumnConfig(weight: 3),
 a!gridLayoutColumnConfig(width: "ICON")
 },
 rows: {
 a!forEach(
 items: local!animal_cdts,
 expression: a!gridRowLayout(
 contents: {
 a!textField(
 value: property(fv!item,"description",null),
 readOnly: true
 ),
 a!textField(
 value: if(toboolean(property(fv!item,"isActive",false)),"Active","Inactive"),
 readOnly: true
 ),
 a!imageField(
 images: a!documentImage(
 document: a!iconIndicator(
 icon: "REMOVE"
 ),
 link: a!dynamicLink(
 value: fv!index,
 saveInto: {
 a!save(
 target: fv!item.isActive,
 value: false
 )
 }
 ),
 showWhen: toboolean(property(fv!item,"isActive",false))
 )
 )
 }
 )
 )
 }
 )
 }
 )
) 
 Hope it helps. 
 Regards.
