question

That code works just fine. Attached is a sample model showing it working correctly.

update-calculated-table.fsm

Run the model, then execute the script whenever you want to update the calculated table.

Note that you pass function_s() a reference to the CalculatedTable object, not a reference to its Table data.

This works:

treenode table = model().find("Tools/CalculatedTables/CalculatedTable1");
function_s(table, "update", 1);

This does not work (although it should; this is a bug which I've added to the dev list):

Table table = Table("CalculatedTable1");
function_s(table, "update", 1);

You can read the information from the table either way.

With a reference to the object, casted into a Table:

Table table = model().find("Tools/CalculatedTables/CalculatedTable1");
return table[1][2];

Or with a reference directly to the data:

Table table = Table("CalculatedTable1");
return table[1][2];
