Whether or not this is a bug, I don't think using an a!forEach is even necessary in the code you provided.

There's no reason to be executing

a!save(
    ri!titoliSelezionati.vendita,
    "Parziale"
)

for each item in the list of selections, since you're just saving the same value over and over.

The forEach also looks like you're rebuilding an entire list (ri!titoliSelezionati) from scratch each time someone selects a new item in the grid. Although this might be easier, an arguably better approach is to figure out which item was added/removed and then do the processing on that item alone. You can do this by comparing your existing list (ri!titoliSelezionati), with the new list (save!value). This would improve the scalability of your solution, if that is a concern.

Are you looking for a way around this to save your values? I also have never use a!save inside a forEach loop.

Yes multiple values(array) are accepted in savaInto as you said but is not accepted an array of a!save inside an a!forEach

es:

saveInto: {a!save(ri!input,1),(ri!input2,2)} is ok

saveInto: {a!foreach(items: ri!array/*{1,2}*/, expression: {a!save(ri!input1,fv!item), a!save(ri!input2, fv!item)})} is not accepted

I have never used a!save in foreach as I feel the best practice is to format the data array first and then use a!save to save into any variable.

Hi,

I didn't understand the above context completely.
But we can save multiple values(array) in SaveInto from selection.

value:ri!gridselection,
saveInto:
{
ri!gridselection,
a!save(ri!selectedID,ri!gridselection.selected)
}
If you select multiple data from grid, those ID's will get saved in array

Thanks,
