question

Hi Julio. The code in your comment looked a bit un-FlexSim 17.2-y so I took the liberty of refactoring it and then found some room for optimization (no pun intended). I cannot guarantee that it does exactly the same as your code, but two problems with what you posted seem to be:

* The variable name and value are set to the same string (gettablestr(tabla, i, 1)) - I assume you have different columns for the name and value?

* The updateOptQuestVars method at the end just gets looked up in the tree but it never gets called

Here's my version:

string nombreTabla = "GlobalTable1";

// Let's get the table by name once and re-use it
Table tabla = Table(nombreTabla);

// We'll use this a lot, so let's do the "expensive" find() operation once.
treenode experimentVariables = model().find("Tools/Experimenter/ExperimentVariables");

// Only destroy the variables we don't need...
int numExisting = experimentVariables.subnodes.length;
int numNew = tabla.numRows;
for(int i = numExisting + 1; i <= numNew; i++)
{
	destroyobject(experimentVariables.subnodes.last;
}

// !! Note: this whole thing breaks if you start with no variables because then
// there will be nothing to copy when you need a new one!!
for(int i = 1; i <= numNew; i++)
{
	// If we can reuse a variable, do that; otherwise copy the first one.
	treenode variable = (i <= numExisting) 
		? experimentVariables.subnodes[i] 
		: createcopy(experimentVariables.first, experimentVariables);

	variable.name = tabla[i][1];
	variable.first.value = table[i][2]; // Assume you meant column 2 here?
}

// Added a nodefunction call here to make sure the update gets done
treenode updateOptQuestVars = maintree().find("project/exec/optquest/definitionLogic/updateOptQuestVars");
nodefunction(updateOptQuestVars);
