If you have a state namedMyState, and a variable namedvMyVar:
$(vMyVar)expands the variable in the default state.
$({MyState} vMyVar)expands the variable in theMyStatestate.
I have a Calendar where each date (field Date) has its Year (column Year); I then have a variable vMaxDate = max(Date) and 2 selectors (List Boxes of the field Year) - one in default state and another in a state PY
when I write in a text box ='$(vMaxDate)' it returns 31.12.2025 ; if 2025 is selected from the first selector.
when I write in a text box ='$({PY}vMaxDate)' and select 2024 from the second selector, nothing is displayed (blank), but if I write =max({PY}Date) in the text box, then 31.12.2024 is shown.
Do you know why variable expansion in alternate state is not working as explained?
I think the linked documentation with it's examples isn't clear enough to the general logic and behaviour of a variable. Better is the description on this place:
which makes rather clear that a variable could have always only a single value at the same time. A field could belong to n states which means that parallel to the system-table a state-table is placed but such logic isn't simply applicable to variables because there is only one value whereby the fields have n ones.
This means you need to apply the state within the expression or by using outer sets before the expression and this expression might be within a variable.
