Exceptions when using default State Gantt chart template with BasicTE

The built-in state gantt chart does not work with the BasicTE library object. State is not updated correctly and exceptions are thrown when the update should happen. Exception is only happening with BasicTE, not with other TaskExecuter objects.

Project below demonstrates the problem.

BasicTE_StateGanttChart.fsm

Image below shows the exceptions during simulation run and that the state gantt is not updated.

Software Version:

FlexSim 22.2.4

@Tdmasure ,a Basic Taskexecuter is an object stripped of almost every typical automated features of a standard object. You have to build most features yourself. If you experience some errors, then it is because there are missing data values a standard object automatically creates.

This is a bug, thank you for reporting it.

Until the bug is fixed, here is a workaround:

Install the chart (on the Advanced panel in Properties)
Open the properties for the Statistics Collector that appears in the Toolbox

Edit the code for the BasicFR State Change Finish and Start events:

/**Custom Code*/
StatisticsCollector collector = ownerobject(c);
treenode listenTo = param(1);
Array objects = collector.Objects.as(Group).toFlatArray();
Array result;
for (int i = 1; i <= objects.length; i++)
    if (isclasstype(objects[i],"BasicFR") || isclasstype(objects[i], "BasicTE"))
        result.push(objects[i]);
result.push(-1);
return result;

Edit the code for the Non BasicFR State Change Finish and Start events:

/**Custom Code*/
StatisticsCollector collector = ownerobject(c);
treenode listenTo = param(1);
Array objects = collector.Objects.as(Group).toFlatArray();
Array result;
for (int i = 1; i <= objects.length; i++)
    if (!isclasstype(objects[i],"BasicFR") && !isclasstype(objects[i], "BasicTE"))
        result.push(objects[i]);

result.push(-1);
return result;

Here is your model with these changes applied:
