Yes exactly, I've tested it yesterday and this works well for a single value.

but I was not sure to use it correctly.

Thank you Stefan

Then passing {a!save(target: local!formAVar: value: null)} to your saveActions will store null to the local variable in form A.

I need to trigger an event when the user select a grid row (or select a inline checkbox).
I do not need the Grid context, but just to call some "save actions" from Form A (not from the interface B).

I could do these actions in Grid B, but I preferer to call them from Form A, because the variables I'm using belongs to Form A.

Example :
When I select a grid row in sub interface B, I need to reinitialize some objects in Form A.

I'm sorry if I am not very clear.

In a saveInto, there is context. This is defined by the component. In a TextField, this is the entered text. In your case, this is the grid selection. To store something else, you define the list of a!save like {a!save(target: local!someVar, value: "someValue"}.

Does this help? Please elaborate about what your goal is.

but how do you do get back these values in form A?
Do you just get an array of value proceeding like this?

In form A :

rule!My_SubGrid_B(
saveActions: {local!var1, local!var2}
)

In sub interface B (grid) :

selectionSaveInto {
a!save(local!test1, "value1"),
a!save(local!test2, "value2"),
ri!saveActions
}

Your selectionSaveInto should look like

{
    a!save(
        target: local!somethingLocal,
        value: "someValue"
    ),
    ri!saveActions
}

Then you can pass a list of a!save() to ri!saveAction

Stefan, it works with a single value, but I may forgot something with an array.
With 2 rule inputs passed in the Save rule input (saveActions), Appian takes only the first value.

In grid B, I set the 2 values like this :

selectionsaveInto: {

a!save(ri!saveActions, {12, 15}),

}

Am I missing something?

That is great, I did not know there were a "Save" type for Rule input.

Thanks a lot Stefan.

Sure. Add a rule input to interface B of type save and make it an array. Then add this to the saveInto. Then you can pass any saving action from interface A into interface B using the new rule input. Give it a try.
